FAN MOTOR TEST PROCEDURE
A simple test can be used to test the fan motor operation. A fully charged 9V battery will be required for this procedure.
FAN MOTOR TEST
This is a test that will verify that the motor does operate.
1. Verify main (240 volt) power if OFF to unit.
2. Remove both wires (brown and black) from the J2 terminal on the fan motor control.
3. Room thermostat should be in OFF position (Unit in idle mode − no heating or cooling demands)
4. Turn main power (240 volt) ON to unit.
5. Connect 9 Volt batter to outdoor fan motor plugs as noted in pic- ture below..
6. Outdoor fan motor should run at a reduced fan speed.
7. If Outdoor fan motor does not run, then replace fan motor assem- bly.
