Whitfield PSC120A-3926 12055902 Stove Control Module Repair Service

Professional diagnostic and board-level repair service for this Whitfield PSC120A-3926 12055902 Stove Control Module.

The Whitfield PSC120A‑3926 (part 12055902) is the digital control board for pre‑1999 Advantage II‑T, III and Plus pellet stoves, providing temperature regulation, fan control, and ignition sequencing. Common failures include a dead or blown main power relay, missing igniter connector on newer models, and burned trace damage from over‑voltage or shorted sensors; the board often shows no output to the furnace or erratic fan operation. First‑check diagnostics: verify 120 V AC input at the board terminals, inspect for visible burn marks or cracked solder joints, confirm that the igniter connector is present (or replace with a compatible 12155912 board if absent), and review any error codes displayed on the stove’s panel.
