An Alma Comfort Club (our maintenance plan) member called because the furnace was not heating and a light on the furnace was flashing red.
What Our Technician Found
That flashing light is on the control board (the furnace’s main circuit board). It blinks in a pattern that points the technician toward the problem. Our technician went through the furnace, checking the burners, the control board, the ignition and the safety controls.

What We Completed
- Checked the flashing light on the control board.
- Inspected the burners and ignition.
- Checked the safety controls and electrical connections.
- Completed a full furnace tune-up.
The Result
The furnace got a full check and tune-up. Learn more about our furnace repair.
What Homeowners Can Learn From This Job
- A flashing light on the furnace is a message. Note the color and pattern before you call.
- Do not keep cycling the power. Turning it off and on can clear the clue the technician needs.
- Check the filter and thermostat. Both are quick things to rule out.
