Carrier 38YCG048 Ignition Control Board
An ignition control board oversees gas intake, the igniter and all the flame sensing devices. It has been a very important board that some manufacturers have decided to blend to be a piece of the main circuit board for safety reasons.
What symptoms are present when the ignition board is dying?
- The initial signal from the primary thermostat does not reach the control board
- Any other problem within the heating and AC system is looked at and turns out to be fine
- Heating and cooling system is unwilling to initiate when it receives a proper signal
