I have a GE cafe model, top fridge and bottom freezer. Recently, it stopped working and I asked a pro to come out to look at it. I have all the fan replaced and everything started working again. I happily pay up. After the pro left and several hours later, I noticed the freezer temperature is not going down. After loosing so much money in one day, I decided to do a little bit google and diy. I used a multimeter to check the continuity of the defrost unit. Saw some resistance. I physically checked the defrost module, and indeed there was ice build up over the defrost thermostat. I used an hair dryer and got rid of the ice and put everything back together and hope for the best. Next day, I checked, the temperature for the fridge is at exactly what I set (37F) and the freezer was not (I set it to 0F, actual reading 47F). Now I am confused, how can my fridge be colder than my freezer? No frost build up both in the fridge and freezer, because I cleared them. All fans are working. Anyone have any idea how to go about next step? Only thing I can think of is maybe replace the main control board, but I don’t want to spend another hundred something nothing knowing if it will actually fix the problem. Thanks.
First, put some independent thermometers in both your fridge and freezer. I suspect your fridge may be reading the wrong temps to you. https://www.amazon.com/CDN-FG80-Refriger… Second, check the door gasket to your freezer to make sure it is properly sealing. A good test is to shut a dollar bill in the door and slowly pull the dollar loose. You should feel resistance when pulling. Repeat this test at different sections of the gasket. The problem could lie in the thermostat and/or the defrost timer. If you provide the model number of your refridgerator, I can provide more specific help.
