Our GE refrigerator does not work properly. There is no cooling in the refrigerator, no air flow or very small (can not feel that even) comes into the refrigerator. There is no cold in the freezer, but I can see the ice in the back wall. I checked the back, the compressor is working, I can feel it is warm (to hot), there is no leaking. There is also a fan, which is working well. I have no idea what happened in our refrigerator!
You stated that there was ice on the rear wall of the freezer compartment. If this is the case then you will want to pull the rear cover and see if the coils are impacted with ice. If so then you have a defrost failure in which you will need to check the defrost limiter to see if it has continuity. If it does not have continuity then you would not need to change it out. You will also want to check the defrost thermistor for resistance. The resistance values should be as follows, 42.5K at 0 degrees, 14.4k at 37 degrees and 5K ohms at 77 degrees. If not within range then it would need to be replaced. If it checks good then also check the defrost heater for continuity. If no continuity then replace and if good with continuity and all other components check ok then you would need a new main control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
I have a Bad PTC MFG-Murata- Part# PTH7M6R8MD2-00 Out of a Holiday freezer with run Capacitor. Mod# LCH0701PW-C1- SER# 14949547DP – Question do you have a replacement or plug in substitute?
Answer Keith, the relay is part number 4356738, the overload is part number 8210241, and the capacitor is part number 8210239. These parts may appear different in appearance however, they are manufacturer suggested replacements and will work on your unit. Thanks.
