I have a three speed ceiling fan that came with my house. It's about 14 years old now. It's never given me problems but right now it won't turn off. The four position wall switch (Off-low-medium-high) still regulates the speed of the fan except for the off position which seems to leave the fan running in low speed.
I'm therefore thinking the fan is probably ok but the switch may need replacement. How long do these wall switches usually last, or is there no known life expectancy on these items?
Also, could I be wrong about the issue and could it be the ceiling fan itself that has a problem?
