2010 Cruiser Furnace

[snlogonz]

My 2010 Cruiser Furnace is not igniting; the fan comes on for a few seconds, then goes out. I read in another forum that the circuit board may be out. Where is the circuit board located? Is it with the furnace? If so, where is the furnace located? Thank you in advance for your help. The nearest dealer is 100 miles away, and I want to take the furnace to the dealer, better yet, the circuit board, instead of dragging the RV to the dealership. snlogonz

I know this sounds simple but have you cleared the gas lines of air by lighting the stove beforeyou try and light the furnace? Are the other gas appliances working? I have had our heater do the same thing if the lines are not cleared of all the air first.

Our furnace is located under the fridge. Look for a wood or metal vent/air intake maybe 2'X2' and the furnace should be behind it.

Thank you. I will look behind the 2"x2" vent under the cabinet; the stove lights without hesitation, but I will light it and leave it lit for a while and then try the furnace again. Thank you so much for your quick reply. snlogonz

Dirt daubbers will also build nest in the burner tube and this will cause it not to light. Also if the Ceramic around the ignitor tip is cracked it will not light.

Thanks for the suggestion, I give the intake and exhaust a cursory look, but I will get the flashlight out and give it a good look. The Furnace is under the sink, so it is hard to get to look at the ignitor tip. The next step to to take off the cover panel. Thanks, again. snlogonz
