Shop Furnace & HVAC Control Boards

If your heating or cooling system is acting up, a faulty control board may be the culprit. Furnace Part Source carries a wide selection of replacement control boards for furnaces, air conditioners, and other HVAC systems. Whether you need a furnace control board, AC control board, or general HVAC circuit board, we offer OEM replacements for major brands like Carrier, Trane, Nordyne, Goodman, and York.

Our catalog is designed for homeowners, HVAC professionals, electricians, and handymen looking to make fast, affordable repairs. Every control board we stock is brand-new, guaranteed genuine, and ready to ship—no minimum order required.

Reliable Control Board Replacements at Your Fingertips

Control boards are the “brains” of your heating and cooling equipment. When they fail, your entire system may stop responding, misfire, or behave erratically. That’s why we carry a variety of furnace control boards with different input/output configurations, ignition types, and diagnostic capabilities to match both older and newer systems.

With over 500,000 HVAC parts in stock and same-day shipping available, Furnace Part Source makes it easy to get your furnace circuit board or HVAC control board delivered quickly and reliably. Not sure which model you need? Our support team is available 24/7 to help match part numbers or recommend replacements.

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.
