Hi,
I recently had an electrician install the Lutron Maestro Ceiling Fan and LED light dimmer wall switch with my new Hunter Duncan Ceiling Fan & Light Kit (model #59199).
The ceiling fan specs say that the two LED lights should not exceed 14W each.
Upon turning on the fan, there is a noticeable humming sound that's centered on the fan housing. I contacted Hunter fan support and they mentioned that it was probably due to the Lutron dimmer switch I installed. They are placing all the blame on Lutron. Of course, they advised me to switch to a Hunter brand fan/light dimmer switch instead.
However, I would prefer to use the Lutron Maestro switch since it has more options and just looks better. I realized that there is a list of approved LED bulbs since I was using the stock LEDs that came with the fan.
I have since tried the Ecosmart brand of LED bulbs (60W) from Home Depot and the humming sound persists. It's very difficult to find the approved LEDs at lutron's website..many of them are out of stock or no longer manufactured. I managed to track down a batch of the approved Philips 60W bulbs on Amazon and am expecting delivery of it tonight.
My question is...how can I be certain that the humming sound is definitely a result of LED bulb incompatibility with Lutron's Maestro switch? Could it be the actual fan is defective? What causes the humming sound?
My plan, if the approved Philips LED bulbs do not get rid of the humming, is to return the entire fan and get a new one of the same model. It's annoying basically I will have to pay the electrician to come back and re-wire then install another fan. Are there any other ways to fix this issue?
