Friedrich BR1224W3A Ignition Control Board
The ignition control board is a safety device that oversees the gas valve, the ignition sequence and other safety devices built into the system. The ignition control board was always an important electronic circuit board that, over the years, has merged to become a standard part of the main board instead of its own individual board.
Indications the major ignition board will need replacing
- Initial communication from the remote thermostat never makes it to the control board
- Ignition sequence will not launch then the thermostat send a signal
- Any other potential problem in the HVAC system is explored and ends up being in good health
