  9 Basic test procedure 
  9.1 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. 
 
9.1.1 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.
