Using a volt-ohm meter check the continuity across the overload, contacts #1 & #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 and 10.00 ohms, a meter capable of these low read-
ings must be used.
1. Check between “C” & “R”. Replace compressor if there is no continuity as the run windings are open.
2. Check between “C” & “S”. Replace the compressor if there is no continuity as the start windings are open.
3. Check between “C” & “R”, or “S” and 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 con-
nections if there is no continuity.

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.

Basically, gear motor problems can be narrowed down to three areas of checkout.
The Gear motor will not run
1. No voltage to the transmission terminals - check external circuit.
2. Low voltage - check supply.
3. Problems in the gear motor electrical circuit. See Figure 21 on page 26.
The Gear motor Starts but Trips Repeatedly on the Overload Protector
1. Voltage - high or low voltage can cause the overload to trip.
2. High gear motor amperage draw, see Specification Chart for ratings and Troubleshooting Guide.
The Motor Runs but Output Shaft does not Rotate
Replace defective gear motor.
CAUTION:
!
Be sure unit is disconnected from the power source. Disconnect the transmission cable.

1. Allow motor to cool and reset overload if necessary.
2. Remove motor end bell and stator, if necessary.
3. Check terminals 1 and 3 on overload. No continuity replace overload. Use a volt-ohm meter. See Figure 19 and
Figure 20 on page 24.
NOTE: Gear motor and related components can be checked from Pin Connector. See Figure 21 on
page 26.
