Unhappy Furnace went Boom

Been working on my 77 Sovereign since picking it up last spring. One little soft spot in the floor led to pulling the floor from the door forward- which led to refinishing the frame (POR 15) which led to - you get the picture..
Any way- this weekend had the furnace running, turned it off- a while later turned it back on and BAM..... Blew the register off the front side of the kitchen cabinet, and blew the bug screen cover off the exhaust about 20 feet against the garage door (scratched door).
I'm guessing- given that the heat vent blew out that the explosion probably ruptured the heat exchanger and realistically the furnace is toast.. I'm just thankful it didn't blow up the trailer.. Any thoughts on what I can do other than a new furnace??

Old furnaces burn about 7 amps an hour. New ones about 3. There's a 'win' in this. It's inside the shell? Make it as safe as possible.

Okay, now that you've established you had a propane leak, are you going to get an LP detector and connect it up so this doesn't happen again? There are several things that run on propane, and we don't like our forums members becoming astronauts.

Thanks folks..Sounds like we will be better off in the long run in terms of power consumption and safety. I'll be putting off the investment in a new furnace as long as I can given the $$$$. Just more blankets for now!

Cowlaws sold me a NT30SP for about $330 (Feb2010). Was well worth it when the unexpected cold fronts hit us in Texas. The night before I got it working the circuit tripped from running the table top "space" heater.

Hi, Greg.

Here is the link you are looking for.

http://www.airforums.com/forums/f427...ers-59777.html in "long form"

Member hshovic actually bought one of the new variable-speed units, and had a bad time with it. I am still waiting and hoping that someone else will buy one, install it, and tell us that it's the best thing since sliced bread.

Might that be you?

Thumbs up Thanks

Thanks for pointing me to the thread.. I started reading but probably don't have time tonite. Moved the AS for the first time in a year this weekend as we finally have pretty much everything -except the furnace back in order. I'm sure I'll get back to this sometime before cold weather sets in. Hoping that we can get by with blankets until then.

hang in there folks

aage and greg-hang in there; as I said in the other thread, as soon as my wallet recovers from buying tires I will buy a furnace. Hank has had and is still having the humming problem with his installation. Based on Hank's experience, I am planning on lots of insulating material around the furnace cubby hole. Gotta balance sound deadening against flammability. I WILL bench test the new unit once I get it and will give noise measurements as close to those I took with the old unit. So, no promises on exactly when, but it will be before Sept. in the meantime, keep looking around.....there may be a better unit out there...

Last I heard you could get a new one from Palomino for about the same price.

I would replace the furnace, but if you want to fix it you probably blew the asbestos gasket off where the burner is bolted into the front of the furnace. It probably had a leak which caused the explosion which finished the job. Did I say I would replace it!

Actually Lumatic is right I did get the furnace from Palamino RV. As it's been said many times on these threads, don't waste your time on an old furnace, too many risks.

yes, aage, that is the unit I plan to buy. 2 burner; 2 speed-I'll see if I can get it quiet.
and in reality, I agree with the idea of replacement, not fixing altho I did research parts for my old unit-mine btw is only 25 years old. but I only want to fix it once. see the other thread on high eff furnaces-it is referenced on this thread above.

Yay! That technology is too interesting to just let it go. Surely the company making it intends to de-bug it!

Sure will, bill, since it was me that referenced it! LOL!

Can't wait till you get one and install it.
