Description
Replace the electronic control board in a compatible manually operated MAXXFAN or MAXXFAN Plus roof vent with MaxxAir part 10B04301K. This is the printed circuit board inside the vent’s control assembly—not the exterior vent housing or the keypad.

- MAXXFAN / MAXXFAN Plus: 4201KW and 4251KW

The 4301KJ and 4401KJ versions use a different board, 10B04301KJ. Verify the complete fan model, original circuit-board marking, revision and wiring connectors before ordering.
