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.
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.
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.
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 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.
Refrigerant gauges are hooked up (Red) High Side, (Blue) Suction low side to the compressor.
Here is the refrigerant recovery process using the tools mentioned above.
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.
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.
How to replace a refrigerator evaporator fan motor in a top-freezer refrigerator. This is for a typical refrigerator.
Tools & parts needed:
The evaporator fan blows air across the evaporator coils and through the refrigerator for cooling. The refrigerator will not cool properly if the evaporator fan motor is not working. If the fan isn't spinning, and you notice warmer
temperatures, then replace the evaporator fan motor.
Unplug the refrigerator power cord before servicing.
Remove the freezer shelf to gain access to the evaporator cover.
Remove the screws to the evaporator cover with your nut driver.
Pull the top down to unplug the evaporator fan motors wire harness.
Disconnect the ground wire (Green) and the ice maker wire harness.
After removing the cover, disengage the locking rings from the tabs.
Lift the fan motor out of the mounting bracket
Place the new evaporator fan motor in the mounting bracket
Reinstall the fan blade onto the evaporator fan motor shaft.
Reinstall the locking rings, plug ice maker harness in and ground wire. Reconnect the evaporator fan motor wire harness then put the cover in position and reinstall the mounting screws then the freezer shelf and plug in the power cord.
This is a basic evaporator fan motor replacement. This method varies for different refrigerators. If you need a qualified service repairman you can book online or give us a call.
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
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.
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.
If you need further help in diagnosing your refrigerator, give us a call or schedule online.

Is your refrigerator is not working?
Easy Checklist of things to look for and test.
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.
Check The Temperature
Reading the temperature of the refrigerator is an easy way to tell if a refrigerator is not working.
Check for Frost Build Up
Ice or frost in a refrigerator can affect the operating temperature.
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.
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.
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.
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 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.
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. If you need a HVAC Repair Service in Las Vegas give us a call or book online.
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.

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:
Diagnosing Washing Machine Pressure Switch Problems
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 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.
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.
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.

The most common types of capacitors for HVAC, Refrigeration & Home Appliances are Dual & Single. There are 2 kinds, A Run Capacitor and Start Capacitor. To test these we will need a Volt Meter. *Warning, good capacitors hold an electrical charge. To prevent shock unplug the appliance and use a screwdriver to touch across the the terminals together to discharge
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.

Gas dryer not heating?
If your dryer displays an error code, that is the easiest way to determine the failed component, if not then lets get right to it, take off the access panels and look at the gas valve, is the igniter lighting? if not take a electrical pen tester or Multi meter and check the ends of the wire leads going to the igniter to check for power, if you have power then you have a bad igniter, if not then start testing the sensors. These sensors usually consist of a high limit thermostat, thermal cut out, radiant sensor, Thermal fuse, thermistor and damp sensor. to check each one of these you need to check the continuity of each sensor with your meter. Some of them you need to check the ohms ( Thermistor and Coils see chart below for values). Also do not forget to clean out the dryer venting system of any lint which can cause the thermal fuse to malfunction.
When you have continuity you usually have a good sensor, if a sensor has no continuity when there is no heat then the sensor is generally bad or stuck in the open position therefor breaking the closed circuit and shutting down operation of heating the dryer. If you do not have a multi-meter, you can also use jumper wires to bypass the sensors, just clip each end where the wires connect to the sensor tabs each individually 1 by 1 with the power cord unplugged, then turn dryer on to see if igniter lights, thus eliminating which sensor it is
Flame come on only for a few seconds?
If you do not have a bad or weak sensor then we recommend replacing the coils on top of the gas valve or the thermistor, this is a common problem usually from natural wear and tear or lint build up in the exhaust vent. Watch the videos below on how to test these components.
