What fault code do you get from the light on the circuit board?
If the ignitor has a strong, consistent, steady spark (weak may sound ok, but there is a difference). Had that problem on my smaller RV. The ignitor tips may appear fine, but the resistance is within.
On the PM, the 8940's blower wheel tossed blades twice. Apparently struck the limit switch one time. Sometimes the furnace would run, sometimes not requiring a reset. Replaced the limit switch (relatively inexpensive) and no more problems.
