The Cooked Suburban Water Heater Control Board.

These are pictures of the PCB removed from the Suburban SW6DE water heater I removed from our 2017 Rockwood. It started only firing on LPG when it felt like doing so earlier in the season, and eventually stopped firing at all. I knew what the culprit was. Between last fall and this year I have now changed out 5 of these boards for other people so this makes 6. All fried in the same spot and all were the same Suburban catalog number and revision number 35-525900-113. But according to Suburban, there are no widespread problems with these boards. They seem to make it past Suburbans 2 year warranty fine as all the ones I have changed have been in rigs owned for around 3 years or so. Our 17 Rockwood was built and purchased in April 2016.

If you have the SW6DE and it has this board, you may want to get a spare to have on hand, Like a Dinosaur UIB-S.
