Safety first: Disconnect power. Overheating issues can present a fire risk.

Step-by-step checks:

Verify external venting: As with airflow errors, ensure the external vent and ducting are clear and properly sized.
Inspect blower wheel: Remove the front or rear panel to access the blower housing. Check that the blower wheel is firmly attached to the motor shaft and not clogged with lint or debris. Replace if cracked or loose.
Check cycling thermostat: Locate the cycling thermostat on the blower housing or exhaust duct. Test for continuity and compare temperature ratings to actual operation (requires heating and monitoring with a thermometer). Replace if it fails to open/close at the correct temperatures.
High-limit thermostat: If the high-limit thermostat is repeatedly tripping, replace it and correct any airflow or cycling thermostat issues that caused the overheat.

When to call a technician: If you cannot identify the cause of repeated overheat trips, professional diagnosis is recommended.
