Overview
Get your stove feeding pellets again when the hopper lid is closed.
The hopper lid switch is a safety interlock: when the lid opens, it cuts power to the auger so pellets stop feeding. If the stove won't feed with the lid shut, stops feeding at random, or shows a hopper-open error, the switch has likely failed or come out of adjustment. Each variant includes one switch.
Which style do you have? ComfortBilt makes this switch in two styles, so match the one already in your stove. Open the hopper lid and look at the switch where the lid closes on it:
- Roller Style: a thin metal lever arm with a small wheel on the end that the lid rolls down against.
- Plunger Style: a short push-button pin that the lid presses straight in, with no lever arm.
Not sure? Send us a photo of your switch or call 1-888-914-0022 and we'll confirm the right one.

Fitment notes: ComfortBilt sells this as a replacement for its pellet stoves and offers no model-by-model split between the roller and plunger styles, so the style already in your stove decides which variant you need. Unplug the stove before replacing the switch.
