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.

    “It doesn’t take a lot of skill to replace a control board”!? Lets say you need to fight an insurance company to receive your proper dues. Are you going to fight them? NO, YOU ARE CALLING A LAWYER! Why? He or she has SKILL and KNOWLEDGE OF THE LAWS! If you have gone to school, obtaining expensive tools, working long hours, additional training due to new efficiency standards, troubleshooting accurately and properly, taking the proper readings as per manufacturers specifications, making sure there are no other reasons for said breakdown, and making sure the system is safe to use afterward, you would not have made that statement. DO NOT FEED THAT NONSENSE TO THE PUBLIC! This is the reason we trained and certified service technicians across the industry have a difficult time with clients.

    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?
