GE refrigerator defrost problem

[brooksjp]

Problem with GE side by side refrigerator, model GSS22WGPACC. 6 months ago it stopped defrosting (coil freezing over). Removed heating element & it was fried, coil/spring in tube was in multiple pieces and burned looking. Replaced it with exact factory part & it worked great for 6 mths. Now its freezing over again, removed the replacement element & it looks great, checked continuity from end to end and is good. What should I look at next?

Thanks, Jimbo

That is one of GE's newer electronically controlled fridge models. The other parts in the defrost system are the 'mother board' (which controls the whole refrigerator) and the thermistor sensors. If the mother board shows physical signs of damage, you've found the problem otherwise such a model can be tricky to diagnose properly if you're unfamiliar working on them.

BTW. GE did have a failure problem with the original thermistors used during production and has since redesigned them. If the one(s) on your model are bullet shaped (have a rounded tip instead of flat like the current ones), they are suspect and should be changed even if not the immediate problem.

Thanks Dan O, will look at board (if I can find it), replaced thermistor already. Board should show obvious sign of damage, right?

No, it might... if you're lucky, making diagnosis easy.
