Technical Overview
Overview & Function
The Dometic 91367 control board governs operation in the listed Dometic systems, a family that includes designs originating under the Atwood name before Dometic manufacture. Control boards in this role sequence heating or cooling calls, enforce safety limits, and drive status indication. A failed board usually presents as an unresponsive or erratic system despite correct supply power.
Fitment & Compatibility
This board fits systems documenting part 91367 in the wiring diagram or old-board tag, regardless of whether the paperwork says Atwood or Dometic. Read the tag before ordering. It mounts in the factory position with original harness plugs.
Technical Construction & Specifications
The board follows the OEM control layout with specification-matched switching, sensing, and protection circuitry. Terminal positions mirror the original so each plug seats once, correctly. Boards are inspected for clean contacts and secure mounting before dispatch.
Installation & Maintenance Guidelines
Disconnect all power sources first. Photograph connections, transfer plugs one at a time to the new 91367, and verify seating and grounds. Restore power and run the full operating sequence from the manual to confirm normal control.
