1970 sovereign furnace

Would anyone recommend repairing one of these or is it just wiser to update? I think it just needs tuning up

A 46 year old RV furnace isn't worth the risk of anything other than a very minor repair in my way of thinking. Safety is my primary concern and even if this is a "looks like brand new", or hardly been used" appliance I would sleep better knowing that a new unit is installed.

Just my view.

I have a 1978 Sovereign and I had some problems with my furnace lighting (NT-30MP). I ended up taking it to a specialist on Suburban furnaces and here's what he found:-Gaskets worn-Burner cracked-Expanded and cracked combustion chamberAlthough he said it COULD be fixed, it ended up being cheaper to buy a new furnace. I'm going to set some cash aside to buy a brand new NT-30SP. In the spring. When the trailer isn't covered in snow.

I'm currently working on my 1976 Suburban NT24SP. It hasn't worked since I bought the trailer 3 years ago. Some mice got into it in storage and chewed through some wires. They seem to be pretty straightforward and easily removed for service. I just enjoy learning how my trailer is all put together and will understand more about my furnace for fun.

If it's original to the trailer, and is a typical fan-forced RV furnace, I would recommend replacement. There are a number of problems common to older furnaces. One is that the fan bearings fail. Another is that the heat exchangers burn through with use. Finally there are some older furnaces that had recalls due to failures of rubber components over time. Replacing the furnace is costly and time consuming but unless you're sure that what you have is good, it's the way to go.

I think that's true as far as the typical fan forced furnaces are concerned.

The older gravity furnaces, such as the panel ray, are another matter. They are less prone to failures, and equivalent replacements aren't readily available.

Check for recalls on your model and serial number. I had a 69 and a 71 both had recalls. I would not take a chance. Replace it. By the way I think that Airstream Supply has 30% off everything in stock until January 31st ( I have no affiliation with them). Now would be a good time to buy one and get it for a low price.

I just emailed them because the code isn't working for anything. I get a message that the code has expired and it's still January. Might not hurt to drop them an email about it and see what they say wen back in the shop tomorrow.
