Carrier 38TKB048 Ignition Control Board
The purpose of the ignition control board is that it has control over gas flow, the igniter and some other sensors. It is an important safety device that some manufacturers have decided to blend to be a part of the main control board for safety reasons.
How can I tell if my main ignition board is about to stop working?
- HVAC ignition cycle is unwilling to initiate when called upon
- Everything else in the system is researched and comes to be all right
- The on-signal from the home thermostat does not get to the main board
