HOW TO FIND A RESTRICTION IN A GE MONOGRAM REFRIGERATION SYSTEM. GE is known for their custom built in refrigerators with a 230v compressor with inverter. After a while through natural wear and tear you will have Poe oil that will slug through the lines and eventually block the capillary tubes causing a restriction.
​Wear to find the restriction? is it in the evaporator coil, the condensing coil or somewhere along the lines located in the walls of the refrigerator. Following the steps below will help aid you in finding the restriction and if possible to clean that restriction out. The steps listed here can be used in refrigeration, HVAC and appliances using the same basic concept.

  1. Power
  2. Recovery
  3. Access
  4. Isolate
  5. Find
  6. Flush
  7. Clean
  8. Weld
  9. Pressure test
  10. Vacuum pump
  11. Weigh in charge

Las Vegas Electrical Panel Repair, Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Electrical Panel
Power. If you reach the electrical plug then pull it, if not find the breaker and switch off the one labeled refrigerator or the appliance name you are working on.

Refrigerant Recovery Tank Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Refrigerant Recovery Tank
Recovery. The Freon inside this refrigerator is 134a. You must use a certified recovery tank with a yellow top and gray bottom to store the refrigerant in. These tanks can range in size from 30, 50 125+ lbs and more. Make sure the out refrigerant line from the recovery machine is hooked to the liquid side (blue) of the recovery tank.

Recovery Machine Las Vegas Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Recovery Machine
You need a recovery machine to take the refrigerant from the refrigerator and transfer it to the recovery tank via refrigerant gauges. Make sure the yellow refrigerant hose located in the middle of the gauges is hooked up to the "in" port of the recovery machine.

Refrigerant Gauges Las Vegas Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Refrigerant Gauges
Refrigerant gauges hook to the high side (Red) & low side (Blue) service port valves and aid in the transfer of refrigerant via the recovery machine to the recovery tank. When both gauges read negative pressure you have successfully recovered the refrigerant.

Refrigerator Compressor repair Las Vegas Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Refrigerator Compressor
Refrigerant gauges are hooked up (Red) High Side, (Blue) Suction low side to the compressor.

refrigerant Recovery Process Las Vegas Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Refrigerant Recovery Process
Here is the refrigerant recovery process using the tools mentioned above.

Access. This GE Monogram refrigerator has a bottom freezer. Unscrew the bottom door panel from the arms extending out. Remove the door and all baskets contained within.
  • Remove the inside arm brackets
  • Unplug fan motor harness
  • Remove fan motor cover
  • Remove ice maker
  • Remove ice-maker wall plate
  • ​remove ice-maker harness
  • isolate the freezer evaporator coil
  • Locate Evaporator coil
  • Remove defrost terminator connection
  • Remove defrost heater connection
  • ​Un-weld capillary tube from high side
  • connect nitrogen tank to gauges, shut off low side (Blue) open high side (red) and push nitrogen through high side. video below.
In the video above as you can see the nitrogen passes through the evaporator coil with no restriction. this tells us the resriction is not located inb the freezer evaporator coil.
TIP: When un-welding the process small tube, use a wire cutter to score the process tube, bend and break loose the copper to open up the hole to the process tube. Use a small guitar string  and push up to see if restriction is in tube. If there is a restriction in process tube, cut tube back or use string to clear blockage.
​After you clear blockage, weld process tube back into evaporator coil.
Move to the process tube on-top of the refrigerator and un-weld the filter dryer and use the guitar string on the process tubes to find the restriction. in this case we found the restriction in the small process tube. We cut back the tube to past the point of the restriction, we weld on a new filter dryer, pressure test and check for leaks to 300 psi with soap bubbles.
Connect Vacuum pump to yellow hose of gauge, open high side (red) and low side (blue) of gauges and vacuum pump to 500 microns or less on the micron meter.
Weighing in Refrigerant Charge on Wireless Scale Las Vegas Quality Service Tech 3349 Casey Dr. Las Vegas NV 89120Refrigerant Scale
Next step is to weigh in the refrigerant charge to manufacturer specifications with a refrigerant scale. You can find the correct ounces or lbs on the nomenclature inside the refrigerator or on the unit you are working on. After you weigh in the charge, plug the unit back in and turn on the power.

These are basic steps to help you in finding a restriction. There are a few more steps in between, if you are a refrigeration technician then you should know all the steps. The important thing is to take no shortcuts. if you need a quality service tech, give us a call.

No water from refrigerator dispenser

2/17/2020

Las Vegas Refrigerator repairWater dispenser not working
NO WATER FROM REFRIGERATOR DISPENSER
You go to get a glass of nice cold water from the dispenser on your refrigerator and come to find out there is no water coming out. Here are some simple troubleshooting tips to find out why and what may need to be repaired.
  • Check Water Filter
  • Check Water Valve
  • Check Dispenser Controls
  • Check Frozen Water Line

Picture
Check Water Filter
​Clogged water filters can restrict the flow of water or completely stopping it.
Depending on the water filter placement on top, below or inside of fridge it is a good idea to replace every few months. After you replace it do not forget to hit the water filter reset button on the control panel and run about 3 gallons of water through it to flush the system and fill the cartridge.

Refrigerator Water valveRefrigerator water & Ice Dispenser Valve
Check Water Valve
A non-working or clogged water valve will not push water through the filter and into the dispenser. Can you hear the valve come on inside or on the bottom back of the refrigerator. These water valves can become clogged with calcium. You can replace them by shutting off the water valve in back of the refrigerator and disconnecting the power wires and hoses.
​Notice most water valves come in a pair, the other one is for the ice maker. If you hear it humming and test it to see if water is pumping through it then you have a good water valve. Proceed to the next step.

Check Dispenser Controls
Are the lights on the dispenser indicating power? if so press in the water dispenser , you should hear the water valve click on. If you don't have power then you have a control problem and need to call a quality Service Tech to properly diagnose the problem. If you have power and no water then proceed to the next step.
Check Frozen Water Line
​If all the above are working and no water is coming out of the dispenser you may have a frozen water line. The reason is because the water dispenser and ice dispenser is located on the freezer side and is susceptible to freezing temperatures while sitting in the line for a while or exposed to lower temp. For this you will need a frozen water line tool to melt the ice. You will need to heat up some water, fill plunger tube, insert line up water dispenser hole and slowly force water into frozen water line till you feel no more pressure on plunger. Test to dispenser to see water flow, repeat as necessary.

How can you tell if your refrigerator is not working?

1/29/2020

How can you tell if your refrigerator is not working?How can you tell if your refrigerator is not working?
Is your refrigerator is not working?
Easy Checklist of things to look for and test.
  • Check Power
  • ​Check Temperature
  • Check for Frost Build up
  • Check Fan Motors
  • Check Condenser Coil
  • Check Compressor
Tools Needed
  • Electrical Pen Tester
  • Screwdriver or Drill Gun
  • Wire Brush
  • Heat Gun
  • Vacuum Cleaner

Check Power
Checking the power is the easiest thing to see first why your refrigerator is not working. Test these components visually and with a electrical pen tester.
  • Do the lights come on when opening the door?
  • Do the water or Ice dispensers work?
  • Does the power cord have a good connection?
  • Is the Breaker tripped?
If the first 2 do not have power or work then pull your refrigerator out from the wall and use your electrical pen tester to test power cord and run it along the length of the cord and if it stops you know you have a short along the way or a break in the line. If no power in the outlet go outside to where the electrical panel and look for the breaker label refrigerator to see if it is tripped. Try to rest it, if it does not reset it could be a weak or bad breaker. if it trips again than you have a short in the electrical line or possibly a bad compressor. In either case you should call a qualified service repair man to asses and diagnose the components.

Check The Temperature
Reading the temperature of the refrigerator is an easy way to tell if a refrigerator is not working.
  • Check the temperature
  • Does the refrigerator have a digital display
  • Does it feel warm?
On the digital display does it show the refrigerator temperature? try lowering the temperature if it does not let you then unplug the refrigerator for 1 minute to reset the control board and display controls. If that does not work you may need a new display control board. Next if you have a Analog thermometer place it in the refrigerator for a while to see if temperature rises or drops. A faster way is to use a digital laser thermometer and point it at the back wall or where the cold air comes out and take a temperature reading. Temperature in a refrigerator is supposed to be 38 to 42 degrees.

Check for Frost Build Up
Ice or frost in a refrigerator can affect the operating temperature. 
  • Is there frost ice build up in freezer/refrigerator?
  • Is the freezer cold but refrigerator warm?
  • Why is there ice build up?
Open up the freezer and see if there is extensive ice/frost build up. If so this can cut down on the air flow through the evaporator coil into the air channel that cools the refrigerator. There are 2 ways you can defrost it. Shut refrigerator off for 24 hours or unscrew the panel that covers the evaporator coil and use a heat gun to defrost it. Be careful to not let the heat gun stay in one place to long as it will melt parts of the refrigerator. Ice build up can be caused by a few things, bad frost terminator, shorted defrost heater and a bad or slow fan motor. You can test these components with a Multi-Meter to check for continuity.

Check Fan Motors
There are evaporator fan motors that pull the cold air flow up and through the coils to keep the freezer and the refrigerator cold. There is also a condenser fan motor that cools the condensing coil either on top or bottom of the fridge next to the compressor. 
  • Is the Evaporator Fan motor running or moving slow?
  • Is the Condenser Fan motor running or moving slow?
You can visually check to see if these components are running. If not or running slow then replace them. If the ice has built up to the evaporator fan motor then thaw it out and see if it starts moving. It is also a good idea to see if there is power running to the motors by checking the wires.

Check Condenser Coil
The condenser coil is a heat exchanger that does just that, expels the warm air from the refrigerator to the outside air.
  • Is the condenser coil dirty?
  • Is the shroud in tact?
  • Is the condenser coil damaged?
The condenser coil is located next to the compressor usually located in the back bottom of the refrigerator outside the cabinet or on top of the refrigerator. A dirty condenser coil will cut down or block the air flow thus not allowing the refrigerator to cool properly. Use a brush to with the grooves of the coil fins, do not go against or you will bend the fins reducing air flow. Take a vacuum cleaner or shop-vac and clean the dust and dirt out.
Next check the black covering over the coil, make sure it is not ripped or torn and in the proper place over the coil. If the shroud is not repairable you need to replace it. When looking at the coils can you see extensive bending of the fins or damage? You can use a fin straightener to bend them back into place. If coil is to damaged you may need to replace the coil. 

Check Compressor
The compressor condenses the Freon or refrigerant and is the heart of the unit that pumps the super-heated gas to the evaporator in turn cooling the refrigerator.
  • Is compressor Running?
  • Is the compressor warm/hot to the touch?
Can you hear the compressor running or feel the vibration? if not use a electrical pen tester and check the wires to the compressor for power. No power then check the run capacitor for any bulging, leaking and the micro-farads with a multi-meter. The Micro-farads should have a reading of 12 on most refrigerators. if more than 2 micro-farads off then replace it.
Is the compressor not running but hot? this could be from a bad run capacitor, low on Freon/improper charge causing it to short cycle or a problem internally with the valves, in that case you need to call a qualified appliance service technician to further diagnose and evaluate the refrigerator as there are many more reasons the compressor can fail. Need further assistance? give us a call so we can answer your questions. Check out our refrigerator repair service if you are located in the Las Vegas area.

Gas Furnace making a Noise? Or not working?

1/21/2020

0 Comments

 
Las Vegas Goodman / Carrier Inducer Motor
Sputnik Inducer Motor
Noisy Gas Furnace or is it just not working at all?
  • Check Inducer Motor
  • Check Amperage
  • Check Flue Gas Pipe for Blockage
  • ​Check Pressure Switch
  • Check Blower Motor
​
How to Check Furnace Inducer Motor
Apart from the bower motor it is a good idea to check the Inducer Motor. The one to the left is a Goodman / Carrier replacement (Sputnik) motor as it gets it's name from the Soviet Satellite design, It is attached to a metal wheel that takes the exhaust from the heat exchanger and blows it out a flue gas pipe. This motor operates in a high heat area in is susceptible to corrosion, loss of lubrication, dirt, dust, grime which can seize the motor or slow it down to natural wear and tear from the elements.
​
​Tools Needed for check: Flashlight,  Amp Meter Power Screwdriver / Drill .
Check Amperage
On the data plate of the furnace find where it says draft motor and read the amperage draw. Using your clamp meter clamp on the wires to the Inducer motor. This is the RLA or Running Load Amps. If the amperage is too high then you have a motor that is struggling or overheating. If amperage is to low then you have a voltage problem to the motor. If the motor is overheating then check the Flue Gas Pipe and Air Pressure Switch in the next steps.

How to check flue gas pipe and air pressure switch
How to check flue gas pipe and air pressure switch
Check Flue Gas Pipe for Blockage.
The flue gas pipe takes burnt gasses and air out of the heat exchanger and vents them outside the house. you can disconnect the pipe from the motor or go ontop of the roof and using a flashlight see if there is any leaves, branches, animals or earth materials built up blocking or partially blocking the exit path causing the motor to over heat and shut down causing your furnace not to run. Some furnaces have control boards that will blink a code helping you diagnose the failed component in the furnace.
Check Pressure Switch
​The air pressure switch pictured above checks the negative pressure created by the inducer motor and tells the furnace if it is performing correctly, if not it will shut the furnace down preventing damage and unwanted carbon monoxide gasses into the house. First check the rubber hoses to make sure they are not kinked, torn or have a blockage. If so clean them out or replace them. Next it could be an electrical failure with the switch being stuck open. For an in depth guide check here on how to test a Pressure switch.
Check Blower Motor
Can you hear the blower motor running? is the air blowing out hard or slow? If it is not running then you have another problem and need to call a qualified HVAC technician out to diagnose as these motors have multiple wires, a run capacitor and limit switches that need to be checked for proper operation.  To find an in depth blower check/test post follow the link.

Washing machine not running / working?
 Most common problems with a washing machine that is not running / working. Most likely you will need a replacement part to get it working again. Here are some common parts that fail in a washing machine.
  • Lid Switch Assembly
  • Water Level Pressure Switch
  • Water Inlet valve
​
Lid Switch Assembly
The lid switch assembly is a safety feature that tells the washer that the lid is closed and it is safe to continue to wash clothes.  Lid switches are generally made out of plastic and tend to wear, bend and break easily do to natural wear and tear or the lid closing hard resulting in the washer not advancing to the next cycle.  People always ask How do you replace a washer lid switch? or How do I fix the lid lock on my washing machine? Kenmore, LG, Maytag, Whirlpool, Samsung, Fisher-Paykel & Speed Queen

Water Level Pressure Switch
The water level pressure switch sits higher than the water towards the top of the machine and tells the control board what level the water is in the drum and when to turn off the machine or water inlet valve. The pressure switches can fail by:
  • Having a hole in the hose attached from the drum to the switch
  • Clogged chamber in the bottom of the drum
  • ​Break in the wire from pressure switch to the control board

Water Inlet Valve
The water inlet valve, pumps fresh water into the clothes washer to wash clothes. Sometimes this valve becomes clogged with calcium and debris then your washer won’t fill with water. These valves have small filter screens that can become damaged, rusted or clogged. If these are not the problems then it could be an issue with the solenoids, or coils, on the valve.

Custom Panel Refrigerator Las VegasCustom Panel Refrigerator
Custom panel refrigerators have 230v compressors that run from a 115v household plug. How is that possible to step up in voltage? A inverter is used to increase the voltage from 125v to 230v. The first thing you check besides power coming in is the inverter. How can you test the inverter? There are 2 things to look for . The common inverter has  2 components to test. 


Common refrigerator InverterCommon refrigerator Inverter
​First thing is to check the voltage on the thermostat wire coming into the inverter shown in yellow to the right. This voltage is DC; if you have an A/C digital voltage tester your reading should be above 50v to ensure the thermostat is working.

Next is the compressor wires voltage coming out of the inverter into the compressor should read at lest 80v to 230v,  if both are within those readings then the next step is to check the compressor ohms.

230v Refrigerator Compressor230v Refrigerator Compressor
How to ohm out a 230v refrigerator compressor.
With these compressors the readings are different than a regular compressor. On a multi-meter from common to run, common to start and start to run all resistant readings should read the same. If more than 1 ohm off then the compressor will not run. You can flip the diagram upside down and it will match.

If compressor is running but the refrigerator is not cooling its a good idea to check the amperage on each leg and refer to the data plate on the refrigerator to make sure it is operating in the LRA range to manufacturer specs. If not then you can have a low refrigerant problem. Then you need to call for a refrigerant leak test or you can test the compressor  yourself with a inexpensive 134a refrigerant leak tester. This refrigerant leak detector can detect R22 R410A R134A CFCs HCFCs HFCs refrigerants. Read our other post on how to do a refrigerant leak test.

Next on the multi-meter turn the dial to the microfarads symbol as you can see in the picture to the left. On a dual capacitor take the black probe lead and touch the terminal on the left and the red probe to the terminal to the right. In the middle pictures above you can see the capacitance next to the uF. the digital reading should measure the same microfarads, if it does not with in 2 microfarads range then change the capacitor out. If you see a capacitor is swollen or damaged in any way, has holes or rusted, leaking oil change it out with a new one.
