Amcor UCHW-H18AF2 Ignition Control Board
The purpose of the ignition control board is that it oversees gas intake, the ignition ignitor and a few other devices. It has been a very important electronic safety board that some manufacturers have decided to blend to be a standard part of the main board instead of having two separate boards.
What to see if the major ignition board is about to stop working?
- The electrical signal from the home thermostat never gets to the control board
- Any other potential problem within the heating and AC system is inspected and seems to be in good condition
- The primary ignition sequence does not start then the thermostat send a signal
