Whitfield Pyro Industries Stove Control Module

The Whitfield Pyro Industries PSC120A‑3766 is a pellet stove control board that manages ignition, fan drive, and safety interlocks. Common failure modes include burned or cracked voltage regulator ICs, failed MOSFET drivers for the burner motor, and corroded relay contacts that prevent fan start; these often manifest as intermittent operation or no heat output. First‑check diagnostics: verify 24 VAC input to the board and confirm proper DC rail voltages with a multimeter; inspect all solder joints and component leads for cracking or burn marks; review any error codes displayed on the stove’s panel (e.g., “E01” for fan failure) before proceeding with component replacement.[oss-gpt-20b]
