Eight or ten years ago, the refrigerator wasn't cooling, so I called a repairman. He said the defrost timer wasn't working and replaced it. It ran fine for months, then quit cooling again, same reason. Having watched him and using your great resource, I knew what to do. Turning the timer every hour or two to keep it cool, I ordered the part and installed it with no problem. You guessed it, same thing happened in about a year. After turning it, it would work okay for a day to a year, then days of turning it manually. Went through the whole process again about a year ago. Installed a new timer.
It works fine on the defrost cycle, but it appears to stop turning at the beginning of the cooling cycle, because it requires a long rotation to get it to enter the defrost cycle. How bad is my luck to have four timers go bad? There must be another answer. What is it?

Here are your parts

See the attachment for the tech sheet.

I am not sure what it is so can only guess.
My guess is that in cooling mode the defrost timer motor is not getting enough voltage/current.

Check the voltage across the timer motor when in defrost and then when in cooling modes.

If it is lower in a cooling mode then I would unplug the unit and check the resistance across the temperature control thermostat when it is closed, should be 0 ohms.
Use your most sensitive meter scale and also short the meter leads together before starting so you know if there is a zero offset in the meter.

If it is 0 ohms then I would say that going through timers is just the nature of this beast.

With luck someone else will chime in who has experience with this particular model.

Thanks for the quick reply and the suggestion. If it is other than 0 ohms, should i replace the temperature control thermostat?
