WARNING!
Drain Pan Heater
The unit uses a drain pan heater to
evaporate condensate moisture created by
the refrigerator cooling process. The pan
heater is energized once the float switch
closes supplying 120 VAC.
To access the drain pan heater, remove
the lower access panel and the drain pan
heater is accessible. Verify the resistance is
approximately 790 Ω.
Verify 120 VAC to the heater and the float
switch is closed. If the switch is closed and
no voltage is supplied, verify wiring, power
disconnect switch has not been turned “ON”,
and supply voltage. If voltage is supplied, the
float switch is closed, and the heater does
not energize, replace the heater.
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless
test procedures require power to be connected. Ensure all ground wires are connected before certifying unit as
repaired and/or operational.
