Level of Difficulty: A Bit Difficult
Time to do repair: 30 - 60 mins
Tools: Nutdriver, Wrench set
Customer: Anthony from Stevensville, MD
Controller board fried
Disconnected power and removed electrical cover
Disconnected wires from old controller one a time and connected to new controller as to not mismatch wire connections. Left new controller hanging off wires.
Raised vent and held using wood blocks to expose gap to use 1/4 inch wrench to undo screws from the inside (poor design for replacing the controller - this was the bulk of my time.) if this didn't work, I would have had to disassemble more of the downdraft.
Installed new controller.
Removed chocks, enabled power and tested...after verified, re-installed electrical cover.
