Carrier 38TXA048 Ignition Control Board
An ignition control board checks gas flow, the ignition sequence and some other sensors. The ignition control board was always an important device that some companies have moved to be a vital part of the main control board instead of its own individual board.
Clues of a failing ignition control board
- The primary ignition sequence refuses to launch no matter what
- Any other device connected to the system checks out swell
- Signal from remote thermostat never turns up at the Carrier control board
