fantastic fan just stopped

Right next to the speed control is a screw in fuse holder. Over time, my fuse holder springs started to lose tension and create an intermittent connection. To fix this you need to stretch out those springs a little and reinstall the fuse.

The fuse panel in one of my old DC power converters used glass cartridge fuses - and the clips that held the ends of each fuse were attached to the panel with rivets.

These rivets were prone to loosening over time, resulting in intermittent connections.

Well, the problem has rectified itself. My wife turned on the bathroom fan and lo and behold, everything now works again. We believe there is a spirit trying to get our attention!!

Remove the wall switch assbly from the wall and pull out the wires as far as you can without pulling anything loose. Check the scotch locks and various quick connects for loose or melted(brown) spots. Doug

This worked for mine. Maybe yours is the same.

One possibility is there’s a Scotchlok splice somewhere in the circuit causing the problem. The possibility that it’s in an area that you can even see to know that it’s there are slim. They are often hidden behind the wall and ceiling panels of RV’s during manufacture.

Here’s a link to a topic of mine where I was lucky enough to be able to find one a few inches away from a light fixture that had been giving me problems. I still had to cut a hole in the ceiling to fix it though.

Trust the spirit! Find the issue and fix it! Electrical issues cause fires and campers burn fast. You know what circuit it is on, start by checking the connections on the lights, fans and in the fuse box.

Your “spirit” needs to be found and tightened.

One thing you can check is the connections on the roof. There is a nut that tightens the connector onto the plungey switchy thingy. If you back it off, clean it up and tighten it down it may come back alive.

Hope you sort it out.

That is the same thing as the metal door light plunger on OLD cars. But, It ONLY affects the fan blade operation. Nothing else. It is a lid open switch and if the nut is loose you lose ground to the fan motor. This link shows what the plunger looks like on the Fantastic. Doug

Nope.

Has to be an intermittent connection somewhere between your DC fuse panel and those three particular devices.

Most likely culprit is a loose wire right at the DC fuse panel - i.e., where it connects to the fuse panel.
