How to Fix / Troubleshooting
Safety First: Turn off power and gas before removing the blower assembly.
- Inspect blower wheel: Remove the blower cover and check for leaves, insects, or debris lodged in the wheel. Clean carefully.
- Check for play: Gently spin the blower wheel by hand. Excessive wobble or roughness indicates bearing wear.
- Listen on restart: After reassembly, briefly power the unit and listen. If noise persists, the blower motor assembly likely needs replacement.
- Replace as assembly: Hayward typically supplies the blower as a complete assembly; replace with the correct model-specific part.
