I have an SW6DE gas water heater in my new Escape
and it failed after the second time we camped with it. Suburban refused to send a new board to me and the only route to service was to wait two weeks and take the camper to a dealer for diagnosis, then return again with the trailer once Suburban sent the part. I found this unacceptable and talked to Escape
They sent a new board and that fixed the problem. There was bad batch of these boards and many of them are probably still sitting in new water heater kits. The bad boards are marked FENWAL. Escape
sent me a different board.
