How to Fix / Troubleshooting
Safety first: Turn off power at the disconnect before testing or replacing components.
- Step 1 – Test capacitor: Check the dual run capacitor value for the FAN section and replace if weak.
- Step 2 – Check motor temperature: After brief operation, carefully feel the motor housing (power off). If extremely hot, the motor is likely failing.
- Step 3 – Inspect wiring: Ensure all fan motor wires are secure at the capacitor and control board.
- Step 4 – Replace motor if needed: Install a Heil-compatible condenser fan motor if overheating or stalling persists.
