Dometic furnace lights and shuts off in about a minute several times and then quits.

I have a new Miramar motor home and the furnace blower comes on and then lights but shuts off after about 15 seconds. It does this about four times and then stops all together. There is the three light code which indicates an ignition lockout fault. Is this user fixable or do I need to go home tonight so I don't freeze?

Thanks,
Don

Sounds like the control board may be wet.

Going thru similar problem with my 2015 ACE. Is the circuit board laying horizontal or vertical? If horizontal, there is a replacement kit to have it vertical at about a 45 degree angle to prevent getting wet.
