Compressor Motor

The compressor motor drives a piston to compress

refrigerant gas. As the piston travels downward

it creates a vacuum to the suction line drawing

in the refrigerant until the piston is to its lowest

point. On the up stroke of the piston it creates a

positive pressure, pushing the reed open and forcing

refrigerant out to the discharge line; thus providing

the means for refrigeration. The motor rests on

springs that are mounted to the compressor shell.

This motor has two windings. One is a start winding

and the other a run winding. The windings are

connected together internally, forming a common

connection. A lead is connected to one end of each

winding and to the common connection.

These three leads are then connected to glass-

sealed terminals that extend through the

compressor case. The terminals are clustered in a

triangle (pyramid) pattern and, reading from left to

right, are identified: Start, Common and Run.

Replacing the Compressor

1. Disconnect power to the refrigerator.

2. Remove the four 1/4 in. hex head screws from

the rear access cover.

3. Recover the refrigerant.

4. Remove the combo device retainer (see Combo

Device section in this Guide).

5. Unbraze the suction tube.

6. Unbraze the discharge tube.

7. Remove the four compressor retaining clips.

8. Remove the compressor.
