International Comfort Products GPSM36L100F Ignition Control Board
An ignition control board may control the gas valve, the ignition timing as well as other safety devices. It is an important electronic circuit board that, in most cases, has become a vital part of the main control board for safety reasons.
Some clues of an inadequate main ignition board
- Initial ignition sequence can not kick in then the thermostat send a signal
- Initial communication from the remote thermostat never does reach the International Comfort Products control board
- Any other potential problem in the HVAC system is looked at and turns out to be just fine
