About a month ago there was some noise coming from our Ref/Freezer side by side. I pulled it out and vacuumed from behind and now the Ref has quite cooling. We turned down the thermostat but still no luck. The freezer seams to be working fine but not the ref. What do you think I need?

Hello, Our GE refrigerator was not getting cool. The freezer was working. The evaporator coils were frosted over. I happened to have a new defrost heater on hand so I used my multimeter and checked for continuity. I replaced the heater and that seemed to be one of only a few issues. I'm not sure if I should now check the defrost thermostat or defrost limiter or what to do as a next step. Any help is appreciated. Thank you, Bryan

I purchased defrost thermostat part # wr50x10068. This came up under the parts diagram for my model refrigerator. When I took apart the fridge however, the thermostat is different looking. The defrost heater is also different as well. Are the parts numbers wrong for this model? The defrost heater in the actual fridge has one wire connector on each side. The heater I purchased, again from the parts diagram for this model #, has two wire connectors for each side and has two heat conductor tubes as opposed to one in the original part I have pulled out. Please advise ASAP!

I have a GE side-by-side refrigerator. The heater was good but still froze up. I replace the thermostat and the freezer worked fine a day or two. Now the freezer is not freezing but is still putting out cold air.

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!
