Frequently Asked Questions

What is a furnace control board?
A furnace control board is an electronic component that manages all of the operations of a furnace—ignition, blower fan timing, safety checks, and communication with the thermostat.

How do I know if my HVAC control board is bad?
Common signs include no response from the system, flashing error lights, or short-cycling. If your thermostat is working but your system isn’t responding, the control board may be the issue.

Can I replace a furnace control board myself?
Many experienced homeowners and handymen choose to replace furnace control boards themselves. However, always disconnect power and confirm compatibility before installation.

How much does it cost to replace a furnace control board?
Furnace control board replacement cost can range from $100–$600 depending on the brand and model. Ordering the part yourself and installing it can save significantly on labor costs.
