Fantastic Fan Quit

You say you have 12V going to the "fan". Does that mean to the motor itself or to the FF assembly?
If someone reverses the direction while the blades are turning, it can/will blow the fuse. I would check that first.

If you have the black motor, keep it as long as you can. It is infinitely better than it's new pancake motor replacement.

Yep but neither is what I'd call a quality motor.

Lippert (who owns the not so fantastic fan company now) believes in buying cheap. The zinc irridite motors are lowest bidder Chinese junk, but the black case one's are only marginally better.

Neither is superlative because of the construction and the fact that neither can be disassembled to lube the bearings or replace the brushes.

The problem is internal. The motors use a flat faced commutator with vertical brushes so brush wear is accelerated and you cannot separate the end bells from the case because they are spot welded, making the only option, replacement. When they start making noise it's time to order a new one because the brushes are shot. Sometimes, whacking the case with a small hammer will dislodge the brushes from the holders and allow some more use, but noise equals it's new motor time in reality.

Great design. The alternative Henigs or whatever they are called is, in reality, a much better setup and cheaper. Fantastic fan is all about maximum profit with minimal quality and they know you'll be buying a replacement motor so they can sock it to you.

Expensive junk, but then a lot of 'stuff' in an RV is expensive junk to replace like the wonderful Jensen sound systems or Furrion TV's. Sub standard junk.
