Diagnostic Steps
| If... | Check | Expected |
|---|---|---|
| The indoor fan motor is not spinning when the system is on | Measure the resistance of the motor using a multimeter. Disconnect the motor from its power source first. | Resistance should be within the manufacturer's specified range (usually between 5-15 ohms). |
