Possible Causes
Open heating element, Tripped or failed high-limit thermostat, Blown thermal fuse, Failed heater relay on main control board
How to Fix / Troubleshooting
Safety first: Disconnect power before testing continuity or removing panels.
- Check thermal fuse: Access the blower housing (often behind the rear panel). Locate the thermal fuse and test for continuity. If open, replace the fuse and thoroughly clean the venting system to prevent recurrence.
- Test high-limit thermostat: On the heater housing, test the high-limit thermostat for continuity. Replace if open.
- Test heater element: Measure resistance across the heater terminals. An open circuit indicates a failed element that must be replaced.
- Inspect wiring and connectors: Look for burnt wires or loose terminals at the heater, thermostats, and control board.
If all heater components test good, the heater relay on the main control board may not be closing. Board replacement is typically required and should be done by a professional.
