GE TFX22ZPBEWW - Trouble manually engaging defrost
Posted 19 January 2012 - 08:43 PM
Had a defective defrost heater...
Bad heater (nothing on my meter on any of the resistance ranges)
Anyway.. I put the new one in today (it's the dual tube model, http://www.repaircli...1X10101/1399613 ) and hooked it up. Get some resistance on the meter, so good sign. It's installed.
I'm trying to advance the defrost timer (which I see under the controls in the fridge, near the light bulb). It makes incremental small clicking noises until the compressor/fans shut off. I then watched and hit the heater several times with a temperature probe (infrared) and did not see it go on. After about 10 minutes (to give the compressor time to cool down), I clicked it two more clicks, in which case everything came back on. It appears that the compressor/fans only shut off at the 3:45PM (or 9:15) across position and the click shortly afterward. In all other positions, everything appears to be working (fans, compressor, etc.)
So, what position do I need to click this in so that the defrost heater comes on?

the position where the Compressor goes OFF
... what position do I need to click this in so that the defrost heater comes on?
Imagine an 8 hour Timer with a number of "clicks"
The Defrost portion is about 1/2 hour.
The Defrost Thermostat (Switch) on the Evaporator may also be bad.

Maybe I read it wrong but it sounds like acadiel advanced the timer into defrost before the thermostat was cold enough to be a closed switch.
I had just defrosted the coils and it was rather warm in there when I tried it. I'll try it again tomorrow morning after it's been sitting all night...
If it still is having issues, I'll get my meter out per the RepairClinic youtube video and test for continuity in ice water...
