OVERLOAD CHECK

Using a volt–ohmmeter check the continuity across the overload, contact #1 and #3. If none, wait for unit to cool down and try again. If still no continuity, the overload protector is defective and should be replaced.

COMPRESSOR CHECK

The resistance readings on the windings will be between 0.25 to 10.00 ohms, a meter capable of these low readings must be used.

1.Check between “C” and “R.” Replace the compressor if there is no continuity as the run windings are open.

2.Check between “C” and “S.” Replace the

compressor if there is no continuity as the start windings are open.

3.Check between “C” and “R” or “S” and the shell of the compressor. If there is continuity, replace the compressor as the motor is grounded.

4.Check between screw terminal on the overload and “C” on the compressor. Check and repair the lead or connections if there is no continuity.

CAPACITOR CHECK

1.Check or replace start capacitor, disconnect bleed resistor before checking for shorted capacitor.

2. Check or replace run capacitor (if supplied) check for shorted capacitor or either terminal grounded to case.
