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.
1.
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.
Water Valve
The All Freezer uses a 120 VAC 35 watt valve
to supply water to the ice maker.
1. To access, remove the lower access
panel and the valve is accessible on
the left-hand side. To check the valve,
ensure water supply, verify coil resistance
approximately 192.2 Ω, and 120 VAC.
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.
1. 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.
