Furnace won't light - simple fix - updated

[Oneilkeys]

The door on my 2016 Axis leaked because they did not install a seal all around th3 door and the way the furnace was installed water leaked directl6 on th3 circuit board - shorting it out - and down the exhaust pipe rusting out the interior so I had to replace the whole furnace. I would check the board as well as blowing it out.

I've owned 4 different RVs over 20+ years and never had to do anything to the furnaces: they just worked when called upon.

Like I said previously...
Take apart, inspect, blow out with compressed air, make any obvious adjustments.

Based on what you’re saying, it sounds like it’s a critter or dirt.

Your control board is probably not the problem.
