Carrier 50EZ Ignition Control Board
An ignition control board regulates the main gas intake valve, the ignition ignitor as well as other safety devices. It is an important circuit board that is now usually a piece of the main circuit board instead of having two separate boards.
What warnings are present when my major ignition board really needs to be replaced?
- Every other problem in the heating and cooling system checked out to be swell
- Signal from remote thermostat does not make it to the main control board
- Ignition cycle does not fire up at all
