I have a 20-year-old ceiling fan that recently got watered (a leak from the even older roof; separate problem) and then dried out. I managed to get it working again, except it used to have six speeds and a working “winter” mode, and now has three speeds with a mostly-broken “winter” mode.
This links to a 20-second movie I took of what happens when using the wall remote to go from lowest speed setting to highest speed setting: https://meyerweb.com/eric/diy/IMG_7759.MOV (20MB; QuickTime format). Hopefully you can see it as well as hear, but the audio should be enough, I hope.
Either way, each “bee-BEEP” is the receiver acknowledging a command to go to the next-higher speed. So the bottom three speed settings cause a brief burst then stop, and the top three settings allow spinning. The “spin briefly then stop” behavior also happens when the fan is first turned on and already set to a lower speed. The top three speed settings appear to be the normal “slow, medium, fast” one would expect from a three-speed fan.
The way “winter” mode is supposed to work is the blades turn slowly for about ten minutes, and then there’s a short burst of speed before settling back down to the slow spin. What happens now is the blades don’t turn at all for about ten minutes, get a spin burst for a few seconds, then slow to a stop for the next ten-or-so minutes.
The pull chains for the fan motor appear to do nothing: neither reverse the direction nor change the fan speeds, even at higher settings when the fan is actually turning under power. I have WD-40ed both the pull chain switches and the fan motor itself, with no change of behavior other than the pull chain switches don’t stick quite as much.
The lights on the fan do work, responding to both the pull chain switch and remote commands, if that makes a difference.
Any ideas as to what would cause this particular set of behaviors, and how to fix it? My searches of the web turned up precious little that seemed to apply to this situation.
