64 Coldspot fridge frosting up

[63kenmore]

Our '64 Coldspot started frosting up on us. The seals all appear to be in good shape. I thought it might be a bad defrost timer, but looking at the parts diagrams on SearsPartsDirect (which does show the proper alliance), found that this unit does not have a defrost timer, but a defrost thermostat. The thermostat is available, but the heater is not.

My question is; does anyone know how to access the thermostat? The drawings don't show how to get to it, and I'd much rather not disassemble anything that need not be disturbed!

Model no.: 106W16EL5
Serial no: 4D110277

Thanks for any support in making this as easy as possible!

Self correction: I found the defrost timer on another diagram. Fortunately, it IS available (and is 30% cheaper than the defrost thermostat). I know how to get to that area in the bottom rear of the unit.

The questions now are; which is the more likely culprit? How might I test the timer for correct function?

Thanks for sharing your knowledge!

My first step would be to locate the timer which you have done, then there should be a slot that a screwdriver fits into. Turn this till you hear it click, this should engage the heater.Let it sit for 30 minutes to let them start defrosting,you should hear or see water going into drain pan. When defrosted the turn screw till it clicks off and compressor starts. This will let you know if one the heater still works and two that the timer motor has stopped. If number 2 happens then you know the timer is bad and the heater is still good. Just replace the defrost timer. If number 1 then you have a heater problem. Hope this helps.
