Sears Kenmore Coldspot fridge won't turn off, model M106.86087761
I tried to drink some apple cider and noticed it was frozen. :)
20 degrees in the fridge, 20 below zero in the freezer.
I turned off the breaker for 6 hours, and the temp rose a lot, 10
above in the freezer and 35 in the fridge.
Turned on the breaker again and temp going down again, to what it was
I assume this is the thermostat and there's nothing to do but replace
What I don't understand is why the webpages often refer to the
"defrost timer", even when the problem it is discussing is "Fridge
won't turn off". Is that another name for thermostat? That doesn't
The defrost timer is a separate unit from the thermostat.
It's function is to periodically )like once a day or so) turn off the
refrigeration compressor and turn on an electric heater which melts any
frost off the refrigeration coils.
A thermostat on that coil senses when it's no longer at freezing
temperatures (i.e. no more ice on it) and restores the normal
If the defrost timer fails, the refrigeration coils frost up so much
that the ice on them blocks the air flow and cold air can't be blown ny
the fan where it needs to go. Since that means the refrigerator doesn't
get cold enough the compressor just keeps running forever trying to make
it colder, but to no avail.
Yeah. Thanks. I also see why my problem and that problem get the
same description. Won't turn off. But in my case, the fridge is very
cold and in the other case, it's not.
I guess I need a new thermostat.
The case Jeff described where the defrost timer had failed. He said
"If the defrost timer fails, the refrigeration coils frost up so much
that the ice on them blocks the air flow and cold air can't be blown
by the fan where it needs to go. Since that means the refrigerator
doesn't get cold enough the compressor just keeps running forever
trying to make it colder, but to no avail."
Okay. Although I had the electricity off for 6 hours and there was no
water on the floor from melting ice that was on the coils.
It sounds like the thermostat is stuck with the contacts closed. Try
unplugging the unit for 1/2 hour every hour and see if the temps come
up but still have the temperature differential. Or, just take the
thermostat apart and see if the contacts open or close, or use a
multimeter to see if the contacts open or close without taking the
actual thermostat apart. Just be careful to remove power first.

Thanks. I'll do that. This is quite a weekend. The fridge broke on
Friday and I found a hole in the furnace on Sunday**. Also last
Friday a week ago the computer monitor broke (although in that case, I
already had a 2nd-hand replacement.)
