Brandy I have a GE sxs model number: gss25qgsc bb. Several weeks ago the fridge side stopped cooling. I then discovered frost on the back panel of the freezer and determined that the coils were completely frozen. After some internet research I discovered that the defrost heaters can be a common problem so I ordered a new one and defrosted the coils with a hair dryer for the meantime. Once the new heater came in I removed the old heater and using a multi-meter tested it for continuity. The old heater tested fine but I went ahead and replaced it to be sure. I also removed the thermostat and tested it for continuity as well to ensure that it was good and it was. However, all of this has not fixed my problem. The fridge will cool for a couple of weeks until the coils freeze over again at which point I have to defrost with a hair dryer to keep things working. Your technician explained that if the heater and thermostat were both working then it would either be the thermistor or the main control board. I have not had been able to replace or check either of those as I was hoping to hire a technician to come out and check the entire unit. However, over the last couple of days the evaporator fan has started turning off and on intermittently every 3-5 seconds. Almost, as if it's not certain whether it should run or not. I've learned if I open the freezer door and leave it open for about 5 minutes the starting and stopping will cease and the fan will turn on and run as normal. I am thinking this may be a sign that the main control board is failing and is likely the culprit for both of the issues i.e. the fans intermittent cycling and the coils freezing over. If not, I assume the only thing left to check would be the thermistor for the coil issue and the fan motor for the fan issue. Is it likely, with the issues I'm describing, that the main control board is the problem for both issues or can you offer any other suggestions?
Answer Hello Brandy. You will need to replace the main board based on the information you provided. Read More... Answered by AppliancePartsPros.com | Monday, September 23, 2013
