Circuit Control Board Replacement in Flagstaff, AZ
The control board is the brain of your furnace. It receives signals from your thermostat and runs the heating sequence step by step, starting the inducer motor, checking safety switches, lighting the igniter, opening the gas valve, and turning on the blower. When the board fails, your furnace may not start at all, may shut down mid-cycle, or may run the blower nonstop. Executive Heating & Air Conditioning diagnoses control board problems and installs replacement boards matched to your equipment, so your heat runs reliably again.

Why Choose Executive Heating & Air Conditioning
We are a family-owned company with roots in the heating and cooling trade going back to 1988. A control board often gets blamed for problems caused by other parts, because it is the component that displays the error code. Our technicians read those codes, then test the switches, sensors, and wiring behind them to confirm the board itself has failed. That careful approach saves you from paying for a costly board you don’t need.
Signs of a Failing Control Board
Call us if your furnace shows any of these symptoms:
- No response when the thermostat calls for heat
- Flashing error lights on the furnace
- A blower that won’t turn on or won’t shut off
- Clicking without the burners lighting
- Burn marks, a melted smell, or visible damage on the board
Control boards can fail from age, moisture, loose connections, or power surges. Electrical storms during the summer monsoon season can damage furnace and air conditioner electronics, so a surge protector on your HVAC system is a smart upgrade. Because the board coordinates other components, we also check parts like the hot surface igniter, pressure switch, and relays during every visit.
