For GE Defrost Limiter Thermostat (Part Number: AP3884317)

Hello, we’re having a problem with our nine year old GE Profile refrigerator. We recently noticed the digital temperature readings were warmer than they should be for both the refrigerator and the freezer. We vacuumed behind the fridge removing quite a bit of accumulated dust and the problem appeared to be solved. About a week later the temperatures were too high again, so we emptied everything out and unplugged it overnight. We plugged it back in the next morning and left it empty. After 24 hours the freezer was down to 12 and the fridge down to 39 but would not go any lower even after 6 more hours. The temps should drop to 0 and 37. We kept the door shut almost continually during our testing period. Internet research lead us to testing the continuity of the defrost thermostat. Our meter showed it had continuity when it was warm, which apparently it should only have continuity when it is cold. We ordered a new one and the new one ended up giving us the same continuity reading. We now don’t know if the old defrost thermostat is actually defective or if we have misdiagnosed our issue. Also, we think the defrost heater is working okay because it has continuity. Please advise, thank you!

ANSWER Hello Cynthia. You need to look and see if the frost pattern on the coils is even from top to bottom. If not, and only half or a small section is frosted, you have an HVAC issue and will need an HVAC tech to repair the unit. If the frost pattern is even, you need to check the fan motor in the freezer and make sure it is running good.
