Trying to light it after, it will light briefly, I will hear a noise from inside the furnace, and the flame is out when I check, I then smell rubber. I tried this several times, always the same result.
So after reading about other furnace tales here, I am taking your advice to replace and not repair.
I would want an automatic lighting model with a minimal amount of hassle. Would another Suburban be the answer or are there better options now and what should I expect to pay for a unit for a professional to install it?
Your describing the behavior of a Suburban furnace, that is loaded with dirt in the combustion chamber. When the combustion chamber has enough dirt in it, it will suck the pilot light out almost everytime it shuts down.
The fix is to remove the furnace from the trailer and disassemble it on a bench.
That's when you will see at least a couple of cups of dirt falling out of it.
After a thorough cleaning, replace all the gaskets.
Bench test the furnace if you can, or reinstall it and start from the beginning.
CAUTION: Attempting to blow the dirt out of the combustion chamber with an air hose, first, will not get enough dirt out, and second, you could damage the combustion chamber.
A good RV repair shop can help you if you wish.
Even though your furnace is over 30 years old, it's not likely that it needs to be replaced, unless the combustion chamber is damaged or has a hole in it.
Again, you must remove the furnace to properly examine or repair it.
