Component Access / Removal
Liquid Line Thermistor Removal
The liquid line thermistor plugs directly into the control
board, with its leads running to the right, then toward
the rear of the unit under the top flange of the right side
panel, down the back of the unit to the condenser dis-
charge/liquid line where it is held to the tubing with a
tube clamp. Foam insulation is then wrapped around
the thermistor and tubing, secured with cable ties.
To remove the liquid line thermistor, first remove the top
cover, control box cover, upper back panel and lower
back utility panel (if a pump model, also remove the
drain pump at this time), then (See Figure 5-30):
1. At top of unit, unplug thermistor from control board.
2. At condenser discharge tube, cut cable ties secur-
ing insulation over thermistor and remove insula-
tion.
3. Loosen tube clamp and pull thermistor from clamp,
then work it up toward top of unit, and out from
under top flange of right side panel toward front of
unit.
NOTE: When reinstalling thermistor, it must be attached
to the condenser outlet with the tube clamp, and the
insulation must be reapplied around the thermistor with
cable ties.

pass through the fan motor mounting bracket and into
the condenser side brackets.
To remove the condenser fan motor assembly, first
remove the kickplate, door, lower hinge assembly, trim
plate, slide cover bracket, water filter panel, back panel
and lower back utility panel (if a pump model, also
remove the drain pump at this time), then (See Figure
