W11549931 Washer Electronic Control Board (Main Control Board, Machine Control, Control Board Assembly)
W11549931 Washer Electronic Control Board
The W11549931 is a genuine OEM Whirlpool-family main electronic control board that manages the washer’s core functions: water valve actuation, motor control commands, drain pump operation, lid/door lock logic, cycle timing, and sensor inputs (water level/pressure, temperature where applicable, speed feedback, etc.). When the board fails, symptoms can range from “dead washer” to intermittent resets, no fill/no drain/no spin, stuck cycles, random beeping, or error codes tied to communication/actuation faults. Common failure modes include relay/triac failure (won’t power a load like pump/valve), power supply issues (no display/dead), corrosion from moisture, overheated solder joints, or damage from surges. IMPORTANT: Many “board” complaints are actually harness/connector, lid lock, drain pump, or pressure hose issues—confirm inputs/outputs before replacement. CRITICAL: Unplug washer before servicing; discharge static and avoid touching board traces.
