How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. Do not run a blower suspected of having water inside.
- Inspect blower housing: Check for signs of water in or around the blower. If water is present, the blower must be replaced.
- Check air intake: Ensure the blower air intake is not blocked by debris or insulation.
- Test blower separately: A qualified technician can bench-test the blower to confirm if it runs without tripping.
- Replace blower: If the blower is shorted or noisy, install a new Coast Spas-compatible air blower.
