Best replacement for Nt-22

[68 TWind]

Having spent most of the afternoon trying to get the heater in my 68 Trade Wind working, I need some advise. The sail switch is bad, relay hangs every 2nd or 3rd try. Also pilot will stay lit a couple of cycles and then go out. I cleaned the unit, and the crossover tube has been replaced and was in good shape (had it outside on a bench). My question is whether to try for new parts and "maybe" it will work, or replace the unit. If I replace, is there a direct replacement for the NT-22, or if not exact, the easiest to install. We don't need the heat a lot here in Mississippi, but when at a full service campground it would be nice to have forced air. I don't have a wall to hang a catalytic, so will use a portable cat. when boondocking.

Thanks for any advice or suggestions on getting the NT22 going.

New parts for an NT22 are very hard to come by if not non existant. Someone in Elkhart has some parts.

Most people who at replacing opt for a NT30. The NT30 needs a little modification, but it's no big deal.

There are other options such as catalytic, which needs crack a window or 2 open, but has a low 12v draw, and a hot water heating system. There are also marine heaters and a marine fireplace people have used.

68,

I just spent a couple of days getting my nt22a to run. What eventually did it for me was taking apart the solennoid???? that has the spring valve in it, pilot outlet, burner outlet and thermocoupler hooked into it. I also did the same with the valve that had the sail switch wires into it. When I took mine apart, I noticed that the spring held valve was kind of stuck as if something got lodged into it. I pulled it apart and wiped the it off, put the whole getup back together and it started to run. While I had it all apart, I used compressed air to clean out the lines also, I don't know if it helped, but it worked afterwards.

Good luck!!
