Whitfield PSC120A-3926 Stove Controller

The Whitfield PSC120A‑3926 is the digital control board for the Advantage II pellet stove series, handling temperature regulation, fan and burner sequencing, and safety interlocks. Common failures on this board include burned or cracked ICs from over‑temperature operation, tripped or corroded relay contacts that prevent ignition cycles, and degraded thermocouple or pressure sensor inputs that trigger error codes. First‑check steps: verify 24 V AC/DC supply to the board, inspect for visible component damage or burn marks, test relay coil continuity and contact resistance, then review any displayed fault codes against the stove’s diagnostic chart.[oss-gpt-20b]
