There are a number of really simple but really confusing things that may be involved here!
When it appears an item suddenly starts working after we pull a fuse and look at it, that pulling the fuse may have actually been the cure!
We don't know the history so this may be a random guess, so keep that in mind!
RV are much more prone to having small points like connections get corroded an not make contact! We use them, store them and when we come back things may fail as we have not been using them which allows corrosion to build more than when we drive our cars every day or so.
Possible the fuse was just not making contact and pulling it and putting it back may have scraped corrosion of the contacts! Or some reset when we take the power off for a period and then restore the power!
Good deal when it works!
As a new user, keep that info in mind for any other times if things appear to not be getting power!
But a note on how RV are different than cars. They are not a single unit, but a collection of parts bought from different builders and put together by Winnebago.
More like your house? The builder built the house but the frig, furnace, air and all those little parts added are built by other people! So when we have a furnace problem , we have to go several different places to get the correct info!
Your furnace has a brand and model number, the thermostat also, and the air conditioner is yet another!
To get the best info on the furnace system, we need info from that builder, the thermostat builder as well as possibly the air cond. folks!
Then we may also need to know what wiring Winnebago does to tie them together!
So do you have a big bag of booklets that should have come with the RV? Maybe a bunch of small books for the furnace, thermostat and each of the other parts of the RV as well as one for the chassis?
Those booklets can be a gold mine of good info and should be protected and prized for the help they can give.
The alternate is finding the brand and model tags on each part and doing a search online for the info but it is much better to just get the books out of the bag!
Rather than go to the dealer for help, most of us learn to do a few simple things to avoid that trauma! A small multimeter to test voltage and continuity can pay for itself almost immediately as time goes on and I highly recommend getting one.
It can save a whole trip if we can chase down something as simple as a corroded fuse!
But knowing just a bit more about the furnace may help.
The fuse sends power to the furnace area, where a board is often involved, then power goes to the thermostat. That is just a complicated set of switches to tell things what you want done.
When you turn the thermostat switches on for blower alone or for heat, the power is then sent back to the furnace to start the blower as a first step.
Unlike at home, the fan comes on first! That is a first step to avoid filling the RV with gas if the blower doesn't work!
If we look at what you describe and the blower did not come on, it pretty well says there was no 12VDc getting from fuse to furnace to stat and back to furnace!
One reason this might happen is the wires were corroded at some point along the way but a second problem is a safety item called "lockout".
RV furnace may lock out starting if things are not done correctly and each thermostat builder may have a different method to reset that lockout!
One way this can happen is if folks are not used to what to expect, turn the thermostat on and then off too soon when looking at what it does!
Check for a book on your stat for some form of lockout and reset process but avoid "playing" with the furnace controls too much until you have more in mind what should happen.
No way I'm saying this is your fault, etc. but then if it is a new RV to you, somebody at the sales lot may have been playing with things and it can happen that way!
Kind of like locking your keys in a car? It's not that hard to do but it can mess with our minds until we figure it out!
Best of luck to you on the new trek and just keep in mind that it gets easier if you do it a lot!!
The fuse is 12V and likely corroded from non-use.
