It's an inline fuse about 8 inches from the Propex. There is also a propane
detector on the circuit. When I put in a good fuse the status light on the
propane detector lights up so I know that's on and working OK. The fuse
blows when the Propex turns on so I think it's most likely the fan motor
that is causing the problem. I'm going to see if I can remove the cover
from the Propex without pulling it out of the van. I'm hoping that maybe
the shaft of the motor is stuck and rotating it by hand will fix the
problem. Unlikely I know but easy enough to try before pulling the Propex
out of the van.
