Need Generic Freezer Wiring Diagram

After I commented on a freezer post last week, my ancient Sears Coldspot freezer has been acting up. Before I unload everything so that I can move it, and hopefully find a wiring diagram on the back, I would like a generic wiring diagram so I can see what possible connections might be. I can get to the defrost timer on the front lower panel, and plan on checking it out, but also curious what other connections might be.

It doesn't have to be a Sears freezer, any old wiring diagram that includes a defrost thermostat would be appreciated. It would help to confirm what I am expecting.

TIA,

H. R.(Bob) Hofmann

Not rocket science! This is for a fridge but should be similar:

Or, many of the large appliance Web sites probably have better diagrams.

Most have a basic wiring diagram on the back. These links might help you also.

Is it frost free? On a Whirlpool refrig., the defrost thermostat is a high temperature (70 degrees F) cutout. I assume only comes into effect when things are out of whack. It's in series with the defrost heater, clipped to one of the brackets that hold the evaporator coils.

You should be able to ohm out the heater+defrost circuit at the timer if the guts are buried down in a hard to get place.

Thanks to all commenters.

I finally got enough stuff out of the freezer to be abe to moce it, it was in an alcove and really miserable to move on a carpeted floor after 20 years in the same position.

Anyway, I was finally able to catch the unit at a temperature of 30 degrees with the timer in the run position, not the defrost position, and the compressor not running. A tap on the thermostat and the compressor started right up and took the temperature down to zero over several hours. So, the problem is surely the thermostat. Now I want to wait until I can move some more of the food out and then replace the thermostat if I can't get at the contacts to polish them. Them a lot of careful monitoring to make sure everything is really ok. I will also replace the timer on general principles, it is at least 25 years old and for $25.00 my local parts store has a replacement. Even if the new unit is mostly plastic, I feel better with a new timer.

Thanks again for suggestions, etc.
