These kits are for over/under refrigerators in locations where the
ambient temp can drop below 55 degrees, causing the refrig thermostat
not to cycle and subsequently thawing the freezer portion. Kit
consists of a small electric heater blanket to be wired in parallel
with the thermostat. It lowers the "inoperative" temp from 55 degrees
to 34 degrees.
Now the question: The heater goes in the small compartment with the
defrost timer and the thermostat, but it goes under the defrost timer
which is several inches from the thermostat. So I'm a little
confused. How will heating the defrost timer affect the on/off of the
thermostat? And since it parallels the thermostat wires, how can it
heat when the thermostat is off due to a cold room?
