Carrier 38YRA036 Ignition Control Board
An ignition control board oversees gas flow, the ignition ignitor and some more sensing equipment. The ignition control board was always an important circuit board that, in most cases, has become a standard part of the main board for safety reasons.
Simple indications of a poorly working Carrier ignition control board
- Signal from home thermostat never gets to the Carrier control board
- The ignition cycle declines to begin when it receives a proper signal
- Everything else connected to the system is inspected and seems to be in good condition
