Another safety feature is the ignition control board, which checks the main gas intake valve, the igniter and some other sensors. It has been a very important electronic circuit board that some manufacturers have decided to blend to be a vital part of the main control board for enhanced safety.
Major symptoms to watch for in a bad ignition board

- Any other potential problem within the heating and AC system is inspected and turns out to be just fine
- The electrical signal from the remote thermostat never does reach the control board
