To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and discharge
capacitor through a resistor before attempting to service, unless test procedures require power to be connected.
Ensure all earthing wires are connected before certifying unit as repaired and/or operational.
Compressor
1. See Machine Compartment, Condenser,
Condenser Fan Access.
Note: Always replace drier when repairing refrigeration
system. Wear eye protection.
2. See Overload and Relay
3. Remove two screws securing condenser fan
shroud to outer case back, if necessary.
4. Unclip machine compartment wire harness from
condenser fan shroud and drier/filter from its metal
clip.
5. Capture refrigerant charge.
6. Remove four 7/16" hex head shoulder bolts
mounting compressor to machine compartment
floor.
7. Unbraze suction and discharge tubing from
compressor.
8. Remove earthing wire screw to compressor.
9. Disconnect electrical leads at overload and relay.
Low Voltage Board
1. See Low and High Voltage Board and Showroom
Switch Access.
2. Remove 4 Phillips screws.
3. Disconnect edge connector from right edge of
board.
4. Take readings at low voltage board.
High Voltage Board
1. Remove toe grille.
NOTE: The high voltage board is in the high voltage
board box mounting on the side of condenser on
20 cubic foot models and on front of condenser
on 27 cubic foot models.
2. Remove the mounting screw holding high voltage
board cover to chassis. Mounting screw on 20
cubic foot models is at front of mounting box.
Mounting screw on 27 cubic foot models is on right
of mounting box.
WARNING
To avoid electrical shock which can cause severe
personal injury or death, discharge capacitor before
handling.
3. Slide box foward (20 cubic foot) or to right until box
rear clip disengages from condenser.
4. Pull box out front of unit.

WARNING
5. Carefully, remove wiring and harness from board.
6. Transfer wiring from old board to replacement
board.
7. Remove mounting screws securing high voltage
board to box.
Power Switch (Electronic Models Only)
Power switch at front of high voltage box interrupts
circuit to high voltage board.
1. See High Voltage Box .
2. Remove two screws mounting protective flap and
switch to high voltage box.
3. Disconnect leads from switch.
Compressor Run Capacitor (Fan Shroud Mounted)
1. Remove compressor compartment rear cover and
heat exchanger cover.
NOTE: On some models special driver (part
#92113P01) will be necessary to remove screws
securing heat exchanger cover.
2. Remove two screws securing condenser fan
shroud to out case back.
3. Unclip machines compartment wire harness from
condenser fan shroud and unclip drier.
4. Remove one bolt from left and one bolt from right
of compressor base pan.
5. Pull compressor base pan slowly towards rear
reforming tubing carefully as necessary to avoid
kinking and pinching.
6. Pull pan out a maximum of approximately 20 cm
(8") from rear. This will allow compressor to be
removed, leak checking of all condenser joints,
and/or replacement or cleaning of condensate
pan. Pulling pan out more than 20 cm (8") will drop
base pan off front glide rail.
7. Disconnect wiring to capacitor.
To avoid electrical shock which can cause severe
personal injury or death, discharge capacitor before
handling.
8. Remove nut securing capacitor to shroud and
remove capacitor.
