Carrier 38YZA036 Ignition Control Board
The purpose of the ignition control board is that it controls the natural gas, the igniter as well as other safety devices. It has always been a vital safety feature that has now become a major component of the main board for enhanced safety.
How do you know when your main ignition board is in need of a replacement?
- Any other device attached to the system is inspected and seems to be in fine condition
- The primary ignition sequence fails to launch even when the thermostat kicks it on
- Initial communication from the remote thermostat never moves to the main board
