Nordyne MS3BC042KA Ignition Control Board
The main ignition control board may control the main gas intake valve, the ignition ignitor and other important devices. It has always been a vital device that is now usually a standard part of the main board instead of having two separate boards.
Indications your Nordyne ignition control board is in dire need of a replacement
- Heating and cooling system declines to initiate then the thermostat send a signal
- The electrical signal from the remote thermostat does not make it to the control board
- Every other device in the HVAC system is inspected and turns out to be just fine
