Refrigerator does not cool.? I have a GE model GSS25QFMB Refrigerator/Freezer. The fridge portion...

I have a GE model GSS25QFMB Refrigerator/Freezer. The fridge portion is holding steady at 65F. The Freezer is still working pretty very well (food on top shelf was starting to defrost).

The hanger-on and condensor is running (I cleaned all that out). The hole between the fridge and freezer toward the bottom be not iced over. I removed the back freezer panel and found the coils be iced over terribly.

It looks close to something is wrong with the defrost circuitry. I'm sure I could replace most of the components; however, I know nought about appliance repair. When an issue similar to this happens, what is the most adjectives component(s) to fail?
Has anyone here or know someone who deal...
Answers:    With that component that has a single defrost stove it is most likely the boiler is bad.

GE is using a radiator in a chalice tube these days. If, after defrost, you look at it carefully (you may enjoy to remove the two sheet metal screws that mount it on to see below the cover), you will likely see that the cup tube is black in one place or the unbroken tube. That means it is adjectives out.

The heater is the element that hangs a short time ago under the bottom of the evaporator.

There is a bimetal, defrost terminator, at the top stuck on the coils, to prevent overheating, that can stir bad too. It is wired contained by series. Those fail sometimes.

But near the single heater it is the oven more times than not. The bimetal has to be terribly cold to close if you ohm it to check.

GE sells the space heater, wiring, and bimetal as one assembly. It have a rubber plug on the end where on earth it connects. Once in in that, it is an easy replacement. Two screw, route the wiring and plug it within.

On rare point I have have a motherboard that controls the defrost fail to defrost but that, as said, is undercooked.

And with that model you can not trigger a defrost. The merely way to testing is to jumper it but I won't try to relate you to do that. Most common, you will see that the oven is burnt.

Good Luck.
