Suburban Furnace
We have a suburban NT 24M furnace, the board is sporadic as it will ignite the burner the odd time and then nothing. We have been told this board is no longer available either as an OEM board or a din...

The standard Dinosaur UIB-L or -S would work- the L would be a direct replacement- no new holes, the S would work fine, drilling one new mounting hole.
You could use the fan control board, but that would require some rewiring, and your model uses the non time delay relay along with a fan switch, which really works pretty well.
Do be aware that furnace is OLD though- you really need to carefully examine the heat chamber, make sure the cast iron burner is clean (but don't enlarge the slots at all), and replace all the gaskets. Suburban offered parts for a while to change the burner to a new Stainless Steel burner, but they stopped.
That said- being old is not an automatic condemnation of a furnace. Old ones were often built heavier.
