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.
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.

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.
