Possible Causes

Restricted airflow causing overheating, Shorted heater coil touching housing, Failed cycling thermostat, Faulty thermistor reading low temperature

Safety first: Disconnect power.

Steps:

Clean airflow path: Thoroughly clean lint filter, internal ducts, blower housing, and exhaust vent. Ensure strong airflow at the outside vent.
Inspect heater coil: Remove heater housing and visually inspect the coil. If any part of the coil is touching the metal housing, replace the heater assembly.
Check cycling thermostat: Test the cycling thermostat for proper operation (continuity changes with temperature). Replace if stuck closed.
Verify thermistor: Test the exhaust thermistor and replace if out of spec.
