 8 Basic test procedure

 8.1 Defective compressor

Compressors are single phase, depending on the model unit. All compressor motors are permanent split

capacitor type using only a running capacitor across the start and run terminal.

All compressors are internally spring mounted and externally mounted on rubber isolators.

8.1.1 Compressor wiring test

Remove compressor terminal box cover and disconnect wires from terminals. Using an

ohmmeter, check continuity across the following:

Terminal "C" and "S" - no continuity

- Open winding - replace compressor.

Terminal "C" and "R" - no continuity

- Open winding - replace compressor.

Terminal "R" and "S" - no continuity

- Open winding - replace compressor.

8.1.2 Ground test

Use an ohmmeter to set on its highest scale. Touch one lead to the compressor body (clean point of

contact as a good connection is a must) and the other probe in turn to each compressor terminal

(see Figure 2.) If a reading is obtained, the compressor is grounded and must be replaced.
