Overview
The main control board (power control module) for ComfortBilt and Alpine pellet stoves — current fully yellow transformer version.
The PCM runs the igniter, auger, blowers and safety switches on instructions from the control panel. ComfortBilt uses it across its ComfortBilt and Alpine models, and every replacement board now ships with the fully yellow transformer; the older half-yellow / half-red board is discontinued.

| Brand | Models |

| Alpine | HP40, HP41, HP42 |
Check your transformer before ordering. Look through the square window in the lid of the black PCM enclosure on your stove.
- Fully yellow transformer: this board is a direct replacement and works with your existing fully-yellow-version control panel.
- Half yellow / half red transformer: you must replace both the PCM and the control panel with the fully yellow versions. The older control panel will not work with the new board — do not connect them together.
The PCM and control panel are electronically matched, so they always need to be compatible versions.
