I have an Atwood furnace that has quit working. I had traced it down to a bad control board. Checked the sail switch, high limit switch, reset switch and all checked out good. Discovered no power to blower motor from the board. Ordered a new board and installed. It worked once after I installed the board and nothing since. Anyone out there have any ideas? I just tested all three switches again and all checked out. Same as before, no power from boars to fan motor. What could be causing this?
Thanks Sean
