Troubleshooting Outdoor Components
Outdoor Fan Motor
Outdoor Motor Winding Resistance Check:
Disconnect power to the unit, all reading are made with no power and fan motor wires disconnected from
circuit board.
Remove the white and orange wire from the reactor and then disconnect the plug from the circuit board. The
chart below will indicate the approximate resistance values in ohms. Readings may vary slightly for different
models. This is a DC brush-less motor, resistance readings may vary with meters. Plugging a know good motor
in the board would provide a quick troubleshooting technique.
