Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
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.

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.

Compressor Check
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 com-
pressor 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.
