Chilly greetings to you all from the foothills of North West South Carolina.

My furnace started a new truck recently. It popped the 15amp blade fuse for the furnace blower. This is what happens....

The thermostat clicks and the blower works normally for anywhere from 5 to 10 cycles. Then without warning the thermostat clicks, the blower engages and within a second or two of the blower beginning to turn the fuse pops.

Seems to me to be a resistance problem in the blower motor, like it is struggling to start from a full stop causing the fuse to overload and pop.

I know some now have a self resetting blade fuse, I have seen people talk about them online, but mine is a simple 15amp fuse.

Camper is a 2002 Montana 285RKS

Anyone else have this issue?

Also where is the blower motor,I looked behind the grill ans found the burner box but see no fan and the burner box is only about 6" tall. Am I missing something?

Thanks in advance for any assistance.
