Possible Causes
Failed inducer motor, Seized inducer wheel, Faulty inducer relay on Thermo Pride control board, Open pressure switch circuit preventing start
How to Fix / Troubleshooting
Safety First: Turn off power before touching the inducer assembly.
- Check for power to inducer (advanced): A technician can measure voltage at the inducer motor when a heat call is present.
- Spin test: With power off, try spinning the inducer wheel by hand. If stiff or seized, the motor assembly needs replacement.
- Inspect wiring: Ensure the inducer motor plug is fully seated and wires are intact.
- Replace inducer: If the motor is noisy, seized, or not receiving proper voltage, have a technician install a Thermo Pride-compatible inducer assembly.
