Furnace issues.

[Madcapper]

I have a 2019 25RES half ton towable fifth wheel and the furnace won't start. Not even the blower motor comes on. Fuse is okay. I accidentally jumped the positive and negative on the fuse box leads and the furnace immediately starts! I put a ground wire from the furnace body itself to the chassis. No difference! Anyone have a similar issue?

No clue. What brand is it and have you checked out YouTube for a search to see if anyone has a fix?

Take an multimeter and ohm the fuse. Sometimes, rarely, a fuse will blow and let voltage thru but not current. I had one the other day that allowed enough thru that the led light that indicates a blown fuse did not light up, but the motor would not run. Or just try another fuse.

And if this is the case, please send me that fuse.....don't throw it away.
