MOTOR CHECK

Continuous Flow Icemaker Service Manual

MOTOR CHECK

The resistance readings on the winding will be between 5 to 25 ohms. A meter capable of these low readings must be used. The start relay cover must be removed.

If no continuity on start or run winding test, replace gearmotor. If continuity on grounded motor test, replace gearmotor.

START RELAY

1.Check between “2” and “4” on relay (with relay unplugged). If there is continuity replace the relay, as the relay contacts should be open.

2.Check between “3” and “4” on relay, if no continuity replace the relay.
