7. Servicing the condenser fan.

Inspect the condenser fan motor by removing the mechanical housing cover to gain access.

Unplug the unit. Clean the fan blade, and turn it to see if the blade rotates freely. If

the motor binds, replace it. If the blade is damaged, unscrew the nut that holds it to

the motor shaft and pull it off. Install a new fan blade, replacing any washers, and

tighten the nut.

To test the condenser fan motor disconnect

the wires to the fan motor. Set a multimeter at

RX10 and touch one probe to each terminal. The

multimeter needle should show approximately 45 to

50 ohms resistance; a lower reading means the

motor is faulty. Next set the meter at RX1000 and

touch one probe to the motor terminals and the

other one to any unpainted metal part of the unit.

If the meter needle moves, the motor is grounded

and should be replaced. To remove the motor

unscrew the bracket that holds the fan motor to

its housing, slide the motor out of the housing.

Remove the fan blade from the old motor and attach

it to the new motor, replacing any washers.

Install the new motor in its housing by screwing

the bracket in place. Reattach the wires to the

motor terminals.

8. Servicing the compressor.

The compressor is part of the sealed

refrigeration system and should be replaced by a

professional service technician. You can,

however, test the compressor and certain

components. Unplug the unit and remove the access

cover to the mechanical housing. A small box

mounted on the side of the compressor protects

the relay, overload protector and capacitor.

Release the wire retaining clip that holds the

cover in place and slip off the cover and the

clip.
