Whirlpool 2183400 defrost timer
Recently repaired my fridge by replacing timer, bimetal, & heater coil - ordered from you.
Successful BUT don't understand something.......
When bench testing the timers (old and new) - I applied 110vac to terminals #1 & #3. Advancing the timer by hand, #1 switched between #2 for defrost or #4 for cooling as expected. BUT, the timer would not advance on its own over a period of several hours (based on a pencil mark) when it was on the bench but advanced properly when installed in the fridge.
I understand there is a capacitor in series with the motor but not sure what impact this would have. Can't sleep for wondering what is happening - thought I had a reasonable understanding of electricity.
PLEASE explain why the timer did not advance when on the bench.
ANSWER Hello David. The timer motor is power through the compressor run of the unit. Ont the bench, you were not supplying power to the timer motor. On the unit, there is power to the timer motor. Thus, the motor advances.
