The Blower Motor On My RV's Furnace Does Not Come On

by Richard
(Timmins, Canada)

The furnace goes on, but the heat coming out from the vents is minimal, could it be the fuses for the Fan or blower? (I noticed the fuses was reversed could this cause the lack hot air coming out)

ANSWER: Greetings Richard thanks for submitting your question on our Ask An RV Question Page.

There could be several causes to the problem you are experiencing, yes it could be a blown fuse. I am not quite sure what you meant by a reversed fuse, but as long as power is flowing through the fuse it should be OK.

It could be a bad blower motor, it could also be due to a low voltage problem in your RV's 12 volt DC system. The Control Board for your furnace could also be bad. I am afraid that there are just too many things that could be causing the problem you are having with your RV Furnace for me to even make and educated guess on what the problem is based on the information you have given me.
