Harbor Breeze Fan lights (3) go out after 20 minutes or so but fan keeps working on a single wall switch. I have same fan in another room works fine. I just installed this one yesterday. I can turn the wall switch off and back on lights come on for 2 seconds and then back out but fan keeps working. Seems to be the same candelera bulbs on this fan as the other ... they came with the fan. Any help appreciated.
In modern fans there is a current limiter, these devices limit the wattage of the lamps and they do go bad, I have had to bypass them in my personal fans but when on the job they have to be replaced in this case it is cheaper to replace the fan. Some are electronic 3 wire and some are simple 2 wire from what I have found. If changing to a lower wattage lamp won't fix it the current limiter is bad.
