Carrier 50TFQ008 Ignition Control Board
The main ignition control board may control the main gas intake valve, the ignition sequence and some more sensing equipment. It has been a very important electronic safety board that is now usually a piece of the main circuit board instead of having two separate boards.
Hints your ignition control board is dead
- The on-signal from the main thermostat does not turn up at the control board
- Ignition cycle refuses to fire up when it is supposed to
- Any other device connected to the system is inspected and seems to be okay
