How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the control board.
- Power reset: Turn off the breaker for 10 minutes, then restore power to see if the fan behavior changes.
- Inspect control board: Remove the top/front panel and examine the board. Look for a relay labeled for the fan output. Check for burn marks or signs of overheating.
- Check wiring: Ensure the fan is wired to the correct terminals and has not been misconnected to a permanent live feed.
If the relay is welded closed or the triac is shorted, the main control board must be replaced. This repair is best performed by a professional.
