I have a simple question about checking (validating) an analog defrost timer. In may ways, this question is not unique to Maytag; it could be for any number of refrigerators.
I don't think I have upload or paste a picture. The kind of defrost timer is the classic one w/ 4 male prongs as follows:
2 1 4 (space) 3
| | | (space) |
In virtually everyone I've seen, the assignment of the leads is s follows:
3 is the line to run the timer motor (connects to blue wire on the Maytag).
4 is the line to run the compressor/condenser fan (connects to orange wire on the Maytag).
1 is the common (neutral) - connects to white wire on the Maytag.
2 is the lead to run the defrost heater (connects to yellow wire on the Maytag).
3 + 1 make the timer motor run, and that is all.
In the main part of the timer cycle (often 8 or 10 hours), 4 would be energized to run the compressor/condenser fan and so 4 + 1 should run a test lamp.
In the 20-30 minutes of defrost cycle, 2 would be energized and 2 + 1 should run a test lamp.
At any given time (position in the timer cycle), either of the above 2 bullets should be happening. It seems to me that one can force the timer into any of the 2 modes by simply turning the manual spindle clockwise to advance the timer.
In practice, I have not had the results I describe above. Can anyone (Jeff?) please confirm that the procedure I outline is correct? If it is, I may well have a defective timer. If not, what is wrong in my thinking?
