Have you cycled the thermostat completly off and on multiple times? It will make only a limited number of attempts to fire up before timing out. You will then have to cycle the thermostat to get it to attempt to start again. This is sometimes necessary if there is air in the line. Might take several attempts to purge the air.

Doing the same fix I had done.
Thank you, I think that's the 1st place on the furnace I'll check. I appreciate the info.

I don't think that's the case. The furnace does nothing, like it has no 12V power, but it does have power.

Is the propane on?

Did you change the mode to "Furnace"?
(Good for you to remember to put it on auto)

Propane is on. Even lit the stove to make sure. My Dometic digital thermostat has four modes: Fan, cool, furnace, and heat pump. Each mode has a green LED next to its label indicating which one is selected. I select furnace, turn the thermostat temperature up above ambient, and nothing happens.

Has it ever worked?

If not, there may be a switch on the unit itself that's turned off. Seen a few reports of that.

I purchased April last year. When I got it home, I tested everything and it worked then.

And you checked at the furnace and there's power at the fuse, but none at the furnace?

Sounds like a wire loose somewhere.
