Carrier 38ARS008 Ignition Control Board
An ignition control board checks the gas valve, the ignition ignitor as well as other safety devices. It is an important device that, in most cases, has become a major component of the main board instead of having two separate boards.
Major indications of a weak ignition board
- Every other device attached to the system checked out to be flawless
- Heating and cooling system is unable to begin even though it is supposed to
- The electrical signal from the main thermostat never moves to the main control board
