I have a GE GSS25JFMAWW side by side with the freezer not getting cold enough. Unlike many of the other posts, the fridge seems fine, the freezer gets cold but not enough to freeze items. I have replaced the Heater and Bracket Assembly as well as the Defrost Thermostat. I thaw the coils, dry the freezer out, plug it back in and the bottom 1/3 or so of the coils are frosted again. The top do not appear to even be cold. The frost on the bottom coils look more like snow, not a frozen block of ice like some of the pics I've seen on here. The fan in the freezer runs fine when I hold the door closed switch and circulates air. I also can make ice cubes. I have not seen if the defrost heater comes on, can I cross the wires that lead to the defrost thermostat to see if it does come on? What does the Sensor Temp Part #AP3185407 do?

I bought the new parts and now think the old parts were fine. I checked the continuity of the older heater and it measured 22, the same as the new one.

Thanks for any help, this site is great.

You have an uneven frost pattern which is a sign of the system being low on freon which requires a tech to find the leak and fix it and recharge the system.

I paid for a service call today after the repairman told me it was probably low on freon. The freon checked out at the right level so know he says it must be a bad compressor valve. He said it's not worth replacing the compressor. Does this sound right or should I get another opinion?
