I have a Ruud Oil Furnace with a NCM300 Panel and 2 zones.
This was installed 5 years ago and never had an issue until lately.
Not always but often the zones stop calling for heat yet the furnace itself, fan too, does not shut down.
This has required a power-off of the whole system, on re-energizing the system seems to work correctly, but then within a couple of days it does it again.
The oil service company doesn't have a clue, I would like to know if the panel is going goofy and needs to be replaced.
