GE refrigerator is not cooling

Recommended Posts

tony tan

Hi,

My GE refrigerator  (PFCS1RKZH SS)is not cooling. both fans are running. compressor is running for a long time because the freeze side is always 33F.  Fridge side is room temperature. I found some ice built up on evaporator coil, but not too much. I jumped J9 and J11 to direct let 110V ac to bypass relay to let heater on. the heater is very hot. so the heater and thermostat is OK. I have changed the new invertor board and main board. the compressor has noise and I can feel vibration. I check there is 110Vac to invertor board and there is 5vDC from main board to invertor board.

 

what will be the problem? thermistor or leaked Freon??

 

please help.

A photo of evaporator frost pattern would be helpful 

 

if you have infrared temperature gun shoot a temperature of the condenser coils and get an ambient room temperature reading as well and report back. 

 

Could be thermistor issue. But let’s try to rule out sealed system issue first.

It has a leak  or restriction in the sealed system, or weak compresor. 

 For futrure reverence. If the compressor runs, and you do not get a conplete frost pattern. Then you have a sealed system problem.( with exception of you may have extreamly  dirty coils.  

 If the compressor runs. Then stop you r diagnoiss unless  you are already willing to put 600 plus into the unit.  So  unless that is the case it does not matter what exactly is  the issue as you  will likely just buy a new fridge rather than put 600-1500 into unit.

Never replace a board ( for no cool) if the compressor runs.

and never replace a inverter  if compressor runs.

For future reference...

No need to view frost pattern if condenser temperature is not 30 plus ambient temperature. Saves a lot of removing items and tearing into unit.

That’s all good for a unit that has a visible condensor

checking the evap is a good idea of what’s happening
