Carrier 50TFQ012 Ignition Control Board
Another safety feature is the ignition control board, which checks out gas flow, the ignition ignitor and other important devices. It is an important device that some companies have moved to be a piece of the main circuit board for the sake of being more efficient.
Indications your main ignition board will eventually need to be replaced
- Any other potential problem throughout the system is inspected and turns out to be good
- Ignition system fails to kick in even when the thermostat kicks it on
- The initial signal from the thermostat never makes contact with the Carrier control board
