Whirlpool ATR1555SPP0 Ignition Control Board
Another safety feature is the ignition control board, which may control the natural gas, the igniter and other important devices. It has been a very important electronic safety board that some companies have moved to be a vital part of the main control board instead of a separate board.
Symptoms to watch for in a bad chief ignition control board
- Ignition sequence declines to begin when it receives a proper signal
- Everything else in the HVAC system checks out okay
- Initial communication from the thermostat never makes contact with the Whirlpool control board
