Not long ago, I had a ceiling fan stop spinning and start making an ever so slight buzzing noise. I thought maybe it was as a result of switching the rotation direction of the fan. Switching it back didn’t change anything either. I just shut off the fan motor to end the buzzing and pondered about how much I dread changing ceiling fans especially since the fan in the living room match this failed dining room fan. I really wanted to repair this Hampton Bay Ceiling fan rather than replace it.
After doing a little Internet research, searching “repair ceiling fan”, I got a lot of cruft and useless information. Next I tried to narrow it down to “ceiling fan not spinning” and “replace ceiling fan motor” to only find more non-solutions. Then I stumbled upon this site that identified the capacitor as a possible cause of failure.
Then I did nothing about it until I was gifted a broken fan.
I had no idea if this donor fan had a compatible capacitor not but it was worth a try. I started out by pulling apart the ceiling fan.
I removed the bulbs, shades then the three screws that hold the light kit in place. Upon removing the capacitor and it was very obvious that the capacitor had failed as it had very prominent bulging on two sides of it.
I took note that this is a 280V 4.5µF x 6µF x 5µF capacitor and decided to do some searching on the web for prices, because, I wasn’t sure how much such a thing would cost. I’m sure you can imagine my happy surprise when I discovered that the donor fan had the exact same capacitor my ceiling fan.
This was enough for me to commit fully the project. I removed the old capacitor, marked the switch side gray wire striped the wire ends to ready it for the donor capacitor. The rest of the wires were in the exact same configuration as the original so wiring this in was trivial.
I used 16-14 AWG Vinyl Insulated Butt Splice and prepared the capacitor to be installed in the ceiling fan. I tagged the gray leg that went to the switch on the donor and checked to see it was the same leg on the crippled unit.
I realized that I wasn’t sure if the motor was damaged or not by the failed capacitor but there was no appreciable risk in trying. After crimping the capacitor into the fan, I flipped the switch and pulled the chain to have the desired result of spinning blades.
I stopped, looked at my success and had a moment of smiling from ear to ear. As much as I liked this look of the light kit hanging down from the fan. I didn’t have any interest in bumping my head into it.
Since the shades were off, I took this as an opportunity to hand wash the light shades, dust the blades and body to shine the thing up before completing its reassembly.
Final Thoughts
I get a lot of satisfaction out of fixing things. I call this project a great success. No money out of pocket and only just over an hour of time invested. How much money did I save? A 52-Inch, 5-blade fan of similar design is about $80 but to have matching fans, I would have had to buy two fans and spend the time removing and installing the new fans. Now, I get to keep my 6 year old fans going just a bit longer and I saved quite a bit of time too. Now, I just have to dispose of the remains of the donor fan in an ecologically sound manner.
