Whitfield PSC120A-3605 12025902 Control Unit Repair Service

Professional diagnostic and board-level repair service for this Whitfield PSC120A-3605 12025902 Control Unit.

The PSC120A‑3605 (cust #12025902) is a solid‑state control board used in Whitfield Advantage II/II‑T/III Plus pellet stoves to regulate fuel feed, ignition, and safety interlocks. Common failures include burned or tripped MOSFETs due to voltage spikes (often above 144 V), failed time‑delay relays, and code 07978 indicating a control board fault; visual inspection frequently reveals burnt solder joints or cracked PCB traces. First‑check diagnostics: verify the input supply is within 98–144 V and stable, inspect for obvious burn marks or loose connections on the board, and review the stove’s error log for any recurring codes before proceeding with component replacement.
