Suburban NT-16-S furnace problem,

[Blue~Go]

...and at least in my model, the air intake is behind the front passenger seat, and can be covered by the bottom of the curtain. (At least, I assume that's the fan intake.)

Just a minor difference, but I believe that is the cold air return. Not that the fan won't use that air, but just to put it in "furnace terms" in case that helps anyone. On my '99 club chair layout it's a metal grille on the forward edge of the seat base, so sounds like the same location.

You're exactly right Blue, cold air return is indeed the correct terminology.

Hey Alan, or anyone else...

My dinette furnace won't light. I do have a spare new Dinosaur control / igniter board that came with the rig.

I know that you actually pulled your furnace to fix it, and I know that's SOP.

My question is, do you think there's any way to replace the board with the furnace still in place? Perhaps loosened at its front?

Thanks! Looking for an easier way out here

I had the same issue, fan cycle, ignition, burner lighting, then going out after 3 seconds to as long as a couple minutes.

Trouble shooting guide states first check board and second gas valve. In my case it's the LP tank regulator.With all my research and reading online about RV life, somehow I missed the RV regulator maintenance item.

Two things come to mind:
1. Change your tank regulator every few years as the rubber diaphram does go bad and they only cost $30. Many carry a spare.
2. When you have a gas appliance issue, you can make sure you have adequate lp flow by lighting all the stove burners and seeing if they will run on high for a period of time.

Now, back to trying to remove the stuck nut holding my reguator to the tank valve.

Cheers,
Bill

That's a good point on the regulator.

You can also check the system with a manometer (obviously your method is a good one too because you don't need a tool).

A note for buying a spare regulator: They come with the relief port oriented either horizontally or vertically (it's kind of like a little horn). Ours are horizontal since the regulator is installed lying on its side.

Now where did I store that manometer...?

[Blue~Go]

I know, I know, who carries one? I have to laugh because I have this friend who is a sucker for every new tool. But then he often "hands down" the old one to me. Hence, I have a manometer (and he has a better manometer ).

I never use a man-o-meter since I got married. It probably will read zero nowadays.
