Carrier 50ZP Ignition Control Board
An ignition control board checks out the gas valve, the ignition timing and other important devices. It has always been a vital electronic safety board that some companies have moved to be a piece of the main circuit board for enhanced safety.
Key signs of a poorly performing main ignition board
- Every other thing in the heating and cooling system is inspected and seems to be just fine
- The ignition cycle declines to activate when called upon
- The initial signal from the main thermostat does not turn up at the main control board
