Carrier 50CR Ignition Control Board
An ignition control board controls gas flow, the ignition sequence and a few other devices. It is an important circuit board that is usually a vital part of the main control board instead of a separate board.
Major symptoms your Carrier ignition control board will eventually need to be replaced
- Heating and cooling system refuses to start no matter what
- The electrical signal from the thermostat never makes contact with the main control board
- Any other problem within the system is looked at and turns out to be in good condition
