Indoor Fan Motor Troubleshooting
To check the condition of the indoor fan motor voltage measurements
and resistance measurements can be compared to the following charts.
Care must be taken when checking voltage measurements, all wires and
terminals must be isolated for safety. Resistance measurements must be
taken with power o and “PG” connector removed from the circuit board.
PG Wire Connector Low Medium High Turbo
Brown - White 130 vac 147 vac 161 vac 225 vac
Brown - Red 148 vac 184 vac 210 vac 340 vac
White - Red 123 vac 150 vac 180 vac 205 vac
e following chart indicates approximate voltage measurements, readings may vary slightly depending on
models and should be used as a reference only. Voltages should be taken with unit running.
PG Wire Connector Resistance (ohms)
Brown - White 97 Ω
Brown - Red 174 Ω
White - Red 78 Ω
e following chart indicates approximate resistance measurements, readings may vary slightly depending on
models and should be used as a reference only. Turn power o and remove connector from circuit board before
reading measurements.
