Ceiling fan works on high for minutes then goes to slow
I have a ceiling fan that was installed professionally 4 years ago. Recently, I noticed that the fan was running on slow. I could switch to high and it would stay for a few minutes and then go back to slow speed. This was a remote Hampton Bay.
I decided to replace the fan thinking it could be a problem with the motor. I installed the new fan. It does the same thing. Runs on high for a few minutes before downgrading itself to slow.
Another strange part: I have it on two switches. One controls the fan and the other the light. When the first fan started slowing down, the switch that controlled the fan stopped functioning (ie would not cut the fan on or off). However, the second switch cut the fan and light both on and off.
I did replace the switches to make sure there was not a problem with them. No luck... same problem. Any help would be greatly appreciated!
