Possible Causes
Failed blower motor, Blocked air intake, Water intrusion into blower, Overheating due to restricted airflow
How to Fix / Troubleshooting
Safety first: Turn off power at the GFCI breaker before servicing the blower.
Blower issues are usually mechanical or thermal.
- Inspect intake: Locate the blower and ensure its air intake is not blocked by insulation or debris.
- Check for water: Look for signs of water inside the blower housing or tubing. If present, correct any check valve or plumbing issues and allow the blower to dry.
- Test blower: With power on, try to start the blower. If it hums or trips off quickly, the motor may be failing.
- Replace blower if needed: Install a compatible American Whirlpool air blower assembly, ensuring proper mounting and hose connections.
Do not bypass thermal protection devices; they are critical for safety.
