I had the same problem with water getting under the circuit board and shorting out a couple of pins. Symptom was that we would come back to camp after a rain storm and find the that blower was running (no burner lit) even with the thermostat off. Sometimes we would see a short cycle with the blower running for a few seconds, shutting off and running again.

Opening up the cover (no lovers), removing the board and drying it (and the puddle under it) would cure the problem until the next rainstorm. I fixed the problem with a strip of butyl tape over the cover flanges and jamming it back in. Hope I don’t have to pull the cover again as I know its going to need some persuading to come off. There was a little bit of foam in the slot that the cover went into, but is was not what I would consider effective weatherproofing.
