What do you do that makes you available to replace 6 boards? I work at a medium size RV dealership(39 years) and I cannot remember the last time I replaced a Suburban control board. Are you positive the area WHERE the board is mounted is not the cause of your numerous problems you have found? Possible wet area or area where water intrusion can get on the board? Doug
I do repairs on an extremely part time basis, more or less as a hobby more than anything. Probably not as part time as I would like because I get a lot of calls. Even though I turn most down I find myself letting my stuff go because I am working on other peoples rigs. It can pay pretty good.
Mine and two others were mounted to the sidewall next to the water heater in the dead space, not anywhere near the tank or floor. Two were mounted to a 1X wood brace they had below the heater tank, and one on a Heartland 5er was just laying loose on the vinyl floor in the dead space of the compartment. Every single one burnt the PCB in the exact same location. Inside the plastic suburban box beneath the foam spacer they stick to it on the back side of the board. I find it hard to believe it's just coincidence. No evidence of water on any of them.
And as far as China, Fenwal Controls is a division of Kidde. Chances are you have a Fenwal board in your sticks and brick furnace or other HVAC equipment.
