I just finished repairing my Fantastic Fan. The fan reversing switch was acting
strange, switch it and it might take several seconds to respond? Finally quit
altogether. Dropped the inner housing down, made a picture of the connections
and removed the wires and switch. Opened the switch up, just a spring mount holds it together. They have two rods on springs that move two copper plates to three positions. This is WELL greased. Removed these and copper plates rock on a center spindle, contact on either end. Well the grease melted and ran on to the
back of the plates and contacts, a good cleaning reassemble and all was fine.
(well almost, I put the top piece on in reverse, so now out is in, and in is out)
