This article outlines the procedure for conducting a continuity test with the compressor.

1. Turn off the power leading to your unit.

2. Look for damage to the wires and compressor itself.

3. Look for burnt or damaged terminals on the compressor.

4. On your multimeter, set the dial to continuity.

5. Find the terminals marked C, R, and S. The terminals should be marked C, R, and S. These letters stand for common, run, and start.

6. Place the pins on the black and red wire from your multimeter onto the terminals. Once you place the pins on the terminals, your multimeter should have an ohm reading of less than 30. Anything significantly above this reading indicates that your compressor may be broken.

7. Place the red pin on C and the black pin on S. Repeat the process, this time checking the continuity between the common and run terminals. Again, the continuity should read under 30.

8. Purchase a new compressor motor if your ohm readings are high or Compressor terminal ohms to ground 0.
