There is a DC 10 amp breaker? Jim

If it is the 10 amp breaker in the furnace, your motor is failing.

I guess so. It's a breaker that's shaped like a cylinder inside of a square box. It's got the number 10 on it, and it pops out shutting down the whole module. It's located at the furnace next to the on/off switch at the furnace. Here's what else I know. I turned it on, waited until the burner lit up. Ran into the trailer and turned the furnace off at the thermostat. Then waited. The blower continued to run, but the burner kicked off. 20 seconds later the breaker popped again.

It's pretty hard to know what you're talking about without a furnace age/model number but from your description it sounds electric and not gas-related.Meanwhile, here are some RV furnace basics in case it's any help: Understand an RV furnace.

That is 12V DC circuit breaker for the blower motor.As suggested..your blower motor is the problem

Atwood RV Furnace keeps tripping 10amp breaker

My Atwood Furnace will turn on, I hear the spark and that ignites the burner. I immediately begin to feel heat come from the exhaust outlet. This runs for 30 seconds, and then the 10amp breaker trips.

I have tried several suggestions I have read on the board already.

Here's what I know:

It is not the propane mixture, I have a solid blue flame on my stovetop.
I have reset all the breakers, turned everything off and back on.
I have two new batteries. They were installed earlier this week and are holding 13.4 volts running in series.
I am plugged into 110V AC, but the same problem occurs if I disconnect and run only off battery.
All my other propane appliances work as they are supposed to.
I have used my air compressor to blow out the outlet. I have also disconnected the circuits on the board and checked them all. I cleaned them and reattached making sure everything was snug.

It doesn't appear to be a faulty connection, or ground as it is working fine, then tripping the breaker about a minute later.

The Furnace is:
Atwood Model# 8525-IV-DCLP

And although I won't rule out the blower motor, it doesn't feel like that is the problem. Everything is working fine for close to a minute. The blower is working and putting out cold air, followed by warm once the burner kicks on. It's about 30 seconds after the burner kicks on that the breaker trips.

It doesn't sound any different, (i.e. struggling).

Does the motor even try to spin? It is likely seized if it does not.
