Drain Pan Heater
The unit uses a drain pan heater to evaporate
condensate created by the refrigerator cooling
process. The pan heater is energized once the float
switch closes supplying 120VAC.
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
120VAC 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.
WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power to unit using power
switch before servicing. Wires removed during disassembly must be replaced on proper terminals to insure
correct earth ground and polarization. After servicing, reconnect power using power switch.
