We have a Hampton bay ceiling fan, it's about 5 years old. Since we had it installed in our new house we have had issues. The first year it would be on low when we went to bed, during the night it would turn up to high and sometimes the light would turn on. We were going to replace it and then all the issues stopped so we didn't. Here lately the fan will be on and the light will turn on by itself or the fan will go to high. It also only works part of the time, sometimes the switch is on for an hour or more before the fan actually turns on. Today, the fan won't even come on now. I had the switch on all day and the fan never turned on, put new batteries in the remote, still nothing.
