About Froze to Death Last Night...Thoughts?

[Mosnowman]

Well not real happy with my brand new 2018 3721RL furnace in 30 degree weather last night. The furnace would kick on and blow cold air only. I checked stove to see if propane was out...it worked fine. Here were the symptoms and what I did with my very limitied knowledge.

Turned on furnace first and set thermostat to 75...kicked on ...cold air only. I could hear a strange noise underneath/outside after a few minutes..I’m guessing igniter was trying to fire?

Turned up thermostat to maximum..cold air only..strange noise continued every few minutes.

We used the furnace a week prior and it worked.

I checked the inside 15 amp fuse and it was fine. Not sure what to do at this point? I purchased it at Camping World in Columbia, Mo. It currently sits on my lake property 2 hours away. I really don’t trust Camping World service anymore so I am wondering about warranty work. There is a local new dealer a few miles from my lake place. Small town...totally trustworthy guy. I have several questions..

What do it yourself steps should I take next?

Do all Keystone Dealers do warranty work even if you didn’t buy the RV from them? This guy doesn’t carry Montana line, but I assume the furnaces are all the same?

Thanks for any help.
