Hello, I have a GE GSS25KSWASS. A couple of weeks ago the fridge wasn't cooling down anymore. I quickly found out that the freezer was...all frozen! I defrosted it manually and checked the heater to find that it was an open circuit! I replaced the heater but after a few hours I started smelling burnt plastic.

It was the heater burning. I, therefore, replaced both the heater and the thermostat thinking that might be the problem... but the heater smells again and I can see the ends of the heater being burnt. I also noticed that during defrost, not only there is quite some bright red glowing, but also the panel covering the heater, coils, etc, gets pretty hot, to the point that it cannot be touched.

After defrosting I can see the temperature of the freezer spiking from -2F to 9F and taking quite a long time to go back (more than 3 hours). I should mention that I replaced the heater with a cheap one found on amazon and not the genuine EOM. Do you think that using a genuine heater would solve the problem? Thank you in advance!

Wouldn't hurt!

With nothing in the freezer?
With the freezer 1/2 full or more the defrost is not as noticeable as the mass of the food helps to hold the temp colder.

Parts breakdown says either could have been used on your model #.

When the heater is bad or shows definite signs of over heating we replace the sensor and thermostat with the heater.

Thank you Jeff for your help!

Yes, the freezer is completely empty, I can probably load it with something.

Ok. I changed the thermostat but not the termistor. I was assuming that because I am able to see a temperature reading on the display the temp sensor was good, but clearly, I am wrong. I will change that too!

Thank you!!

Hi Jeff,

With the freezer half full the situation is now better, I see less temperature swing and faster recovery. I do still notice that the food/bottles etc are covered with ice after a defrost cycle. The smell is still there, but I am waiting for the genuine heater to arrive. One more observation: the pink wire of the heater is connected to the ground. I checked with a multimeter and I can see that there is a short between the pink wire and the ground wire/chassis...is it supposed to be like that?

Great!

The pink on a GE often goes through the defrost thermostat to the neutral....while neutral and ground are really the same thing, they should be separate.
A real "short" would trip the breaker or blow a fuse.
