Carrier 40QAC060 Ignition Control Board
The ignition control board is a safety device that regulates gas intake, the igniter and the flame sensing circuits. It has been a very important electronic circuit board that, in most cases, has become a standard part of the main board for safety reasons.
How do you know if your ignition control board is on its last leg?
- Initial ignition sequence is unwilling to start when it is supposed to
- Every other device within the furnace checks out swell
- The initial signal from the home thermostat does not reach the main control board
