For Legacy ComfortBilt Pellet Stoves (Pre-2020 Models)
Restore full system functionality with a direct-fit replacement PCM (control board) designed for legacy ComfortBilt pellet stoves using 20-pin ribbon cable systems.
✅ Compatibility (Read Before Ordering)
This PCM board is designed ONLY for older ComfortBilt stoves that use:
20-pin serial ribbon (flat) data cable connection
Typically manufactured before 2020
❌ Not Compatible
This motherboard WILL NOT WORK with:
❌ Newer ComfortBilt systems using 4-pin (USB-style) cables
❌ Updated PCB/control board configurations (post-2020 revisions)
⚠️ If your stove uses a small 4-wire connector instead of a wide ribbon cable, this is not the correct board.
