Furnace Blowing Fuse

Hi everyone, New to the RV world. Having trouble getting my furnace to turn on. I noticed the 12vdc fuse was blown, tried another and blew. Im guessing short on wire somewhere or locked up blower motor. Just bought this fifth wheel and don't know much about it. What would be next step to check?Where is the blower motor? Would appreciate all the help.

Thank you

Welcome to Forest River Forums!

The Fan is inside the furnace. It's all a self-contained unit. There are several documents for the furnace in the FRF library. Here's a link to the trouble-shooting guide to get you started. http://www.forestriverforums.com/for...do=file&id=119

I image the power to the furnace is connected thru a plug so the first thing to do is to unplug it at the furnace to see if the short is in the wires leading to the furnace or in the furnace itself. Good luck!

The furnace uses only 12v (and propane). Fuses in an RV are for 12v. Circuit breakers are for AC (120v).

The fuse block has a 15 amp 12vdc fuse and the wire that is protected by the fuse goes behind the wall somewhere. Don't know if I answered your question.

Ford Idaho, The Ac I was talking about is on the control module on the furnace. Now what the Ac does I don't know but it is AC Voltage.
