Still have the wonderful GE fridge you guys helped me diagnose and repair years ago. In a nutshell, bottom drawer freezer appliance, the unit was not defrosting properly so ice would build up under the coils, block off the drain and eventually (takes about a month...) builds up to a point that the fan gets stuck in it and the top fridge warms up. The freezer stays ice cold. You gave me the diagnostic procedures and I determined it was the defrost timer. That was the first time. The timer lasts anywhere from 9 to 15 months or so and then fails again. Once it actually turned out to be the thermostat about 3 years ago.
So, I end up once a year taking this thing apart, melting the ice so it drains (never has had a blocked drain, just covered over with ice), replacing the timer and restarting the countdown. As I'm doing this again and shopping for a timer, I came across a few others that got me thinking. This unit calls for a WR9X483 10hr/35min timer, what are your thoughts on a different timer, like a WR9X480 which is a 6hr/30 min? I have no idea why the timers keep failing. I've tried genuine GE and aftermarket. My thoughts are, outside of crappy, under-rated design, that I have the fridge in a tight alcove with very little room to breath so maybe it's affected?? Or, now I'm thinking that it isn't melting all the way so maybe changing the timer timing might help?? The only other thing, which baffled a local tech when I needed a timer quickly and bought it locally, is that the thermostat isn't clipped to the coils, but onto a distinct mount on the pan under the coils. I always though that was odd, but it is definitely how it came from the factory (took photos when I first took it apart...).
So, any thoughts on why this is a recurring problem, and do you think that a different defrost cycle or changing the clip to the coils would help, or make any difference at all?? Or do I just keep repairing it until I can afford to take a sledge hammer to it and replace it??
I defer to your collective wisdom...
