3. Remove rear, left and right side meat
saver ducts and disconnect wiring. Lower
fan is now accessible.
Fan measures approximately 3.2 Ω.
4. Reverse procedure to reinstall.
Float Switch
The unit uses a float switch to activate the
pan heater which in turn dissipates water
from the defrost cycle. When the switch is in
the down position, the switch reads open and
when the switch is in the up position it reads
continuity.
To access the float switch, remove the lower
access panel and the switch is accessible
on the left hand side. Loosen the securing
nut, disconnect wiring, and repair/replace as
necessary.
Drain Pan Heater
The unit uses a drain pan heater to vaporize
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.
