Carrier 50JZ036310 Ignition Control Board
The purpose of the ignition control board is that it controls the natural gas, the ignition ignitor as well as other safety devices. It has always been a vital safety device that, over the years, has merged to become a part of the main control board for the sake of being more efficient.
Subtle cues of a barely functioning major ignition board
- The main ignition cycle refuses to commence even when the thermostat kicks it on
- Any other device within the furnace checks out good
- The on-signal from the thermostat does not get to the Carrier control board
