Carrier 48GX030040300 Ignition Control Board
The main ignition control board keeps an eye on the gas valve, the ignition sequence and some more sensing equipment. It has been a very important electronic circuit board that has now become a standard part of the main board instead of its own individual board.
What signals that my major ignition board is almost going bad?
- The initial signal from the primary thermostat never makes contact with the main control board
- Heating and cooling system can not activate even when called upon
- Everything else in the heating and cooling system is explored and ends up being OK

Before buying or ordering do your best and cross-check the correct model as well as make a visual inspection so that you are positive that the correct replacement ignition control board is the one being purchased. You do not need to install the part by yourself. Locate a pro in your community to do it for you.
Feel free to download your manual for help.
