How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. Do not operate a blower that has taken on water.
- 1. Identify the device:
- Press the blower/aux button on the topside panel to confirm which output triggers F6.
- 2. Inspect blower assembly:
- Locate the air blower in the equipment bay or nearby compartment.
- Check for signs of water inside the blower housing or tubing.
- If water is present, the blower must be dried or replaced; do not power it up.
- 3. Check wiring and connections:
- Ensure the blower plug is fully seated in the correct socket on the control pack.
- Look for burned or melted connectors.
- 4. Test with blower disconnected (qualified person):
- With power OFF, unplug the blower from the control pack.
- Restore power and see if F6 clears. If it does, the blower is likely defective and should be replaced.
- If F6 persists, the control board’s blower circuit may be damaged.
- 5. Replace components:
- Install a Wellis‑compatible blower with the correct voltage and amperage.
- If the board is faulty, have a technician replace the control pack.
