This board runs the ignition sequence, auger feed and blower functions that keep a pellet stove operating on schedule. The Enviro Circuit Board (part 50-178) replaces the worn control board in compatible Enviro pellet stoves built before July 2006, and does not include a thermostat switch.

Purpose

The circuit board controls the core operating functions of the pellet stove. As an electronic component, it can fail over time, particularly without surge protection on the circuit.

Key Benefits

• Direct-fit replacement for the original pre-July 2006 board — no modifications needed
• Genuine Enviro part, not an aftermarket copy
• Restores normal ignition, feed and blower control
• Matches the exact no-thermostat configuration of the original board

Other Notes

Unplug the stove before removing the old board, and handle it with care during removal since these boards can break if forced.

Fits 4 compatible models on record. Customers replacing this board often also inspect the corresponding board decal, wiring harness connections, and the thermocouple or snap disc feeding it, since these commonly show wear at the same time.
