| Symptom | Part to check |
|---|---|
| Won't light | Gen 3 quartz igniter |
| Pellets not feeding | auger motor or vacuum switch |
| Low temperature alarm / shuts down | proof of fire switch |
| Smoke or air leaking at the door | front door gasket |
| Room blower noisy or not running | HP22i room blower assembly |
| Screen blank or unresponsive | control panel or PCM control board |
Older insert? If the cable between your control panel and PCM is a wide 20-pin ribbon (most units built before about 2020), you need the legacy PCM board and legacy HP21/HP22i control panel instead.
