Nordyne M3RL Series Ignition Control Board
The purpose of the ignition control board is that it checks out the main gas intake valve, the igniter and a few other devices. It has always been a vital circuit board that is usually a major component of the main board for safety reasons.
Signs your ignition control board will die soon
- HVAC ignition cycle declines to kick in when it is supposed to
- The on-signal from the remote thermostat does not turn up at the main control board
- Every other thing connected to the system is inspected and seems to be a-OK
