Question about GE Monogram ZISx420DR 42-inch Side by Side Panel Ready Built-In Refrigerator with Dispenser
Our unit is a GE Monogram side by side which is about 19 years old. About 3 weeks ago, the freezer stopped freezing and the refrigerator stopped cooling but the light inside still functioned. Cleaning the condenser and turning the electricity on and off had no effect. After a few days the freezer and refrigerator started working again and they have seemed to operate fine since then. Trying to figure out:
whether to call a repair person or just replace the unit
what type of repair to even suggestI also have the same problem. GE ZISW42EM Upon return of a 3 week vacation I found the front panel displaying defrost alarm, the fridge was about 48 degrees but the freezer still was below zero. A few days later a new alarm came in indicating freezer was in high temp and it was about 25 degrees. I have had the compressor changed out my a serviceman 5 years ago, they reused the R-12 but put a small amount of hot shot in. Today, the GE service guy came and said since the compressor was not OEM he couldn't help! Not a very good answer. I am a busy person and was hoping to get service to fix. I am mechanically inclined and have my universal refrigerant license, but I am trained in large water chillers not small appliances. I cannot locate the wiring diagram inside the unit, it's gone. I do suspect the defrost circuit, but also want to validate the refrigerant circuit. What temp\pressures should I be looking for with gauge set to see if system is healthy, does anyone have a wiring diagram? I have R420a, which I understand is a direct drop in replacement for R12, just weigh in 90% of factory charge to start. Can anyone give me some DIY assistance. Thanks!
This is rather like an advice to you:-
Please just call a repair person. It would not cost you much like the pain you already giving yourself cracking your brains.
It will be well fitted if an expert handles the situation.

Check the condenser fan motor and make sure it is running. Sounds like the compressor is not running long enough. Check also the freon. Make sure that the fridge has freon.
This is just a suggestion. I hope it would help. Thanks.

Two possible problems with the fridge/freezer. #1 The freon or compressor is going out or #2 The thermometer sensor or temp control is going out. I will look on www.retrevo.com for a free repair manual for you system. Do you know the model number of your system? It may be located on the compressor or a stick on inside door or in back bear coil rack

From description sounds like a possible fault on defrost system, you should test the DEFROST THERMOSTAT (THERMO PKG) and the DEFROST CONTROL (Defrost Timer).
Here all parts and diagrams for your appliance , call them to get a wiring diagram, and operating temp for specific model.
Parts also here.
