First be sure the board is bad. This often requires a HVAC tech to look at the furnace since there are so many variables.
The control board should have a LED that flashes error codes. The codes often are listed on the panel door or somewhere in the unit.
If you have already gotten this diagnosis from a HVAC company more than likely that is the problem.
Buying the correct board online is the next step.
I personally usually use Amazon but this is simply a personal choice as they have a large selection eBay also has a good selection.
If you order a board be sure to match the part number from the old board or the name and model of the furnace.

Every furnace will be slightly different and the manufacture directions should always be followed.
1…Unplug the furnace.
2…Take picture with your phone of the wiring and possibly a video. Simply be sure you have a reference to fall back to for what wires went were.
3..Before handling the new board ground your hand on a metal surface since static electricity can damage control boards.
4…Remove the screws holding it in place. Try to leave the wires attached if possible, if this is not possible than transfer the wires one at a time to the new board.

    Our control board actually burned up. HVAC guys think we should replace the whole furnace because we don’t know what caused the fire. Could the fire have been just the control board itself?
