I am troubleshooting some electrical issues on three different ceiling fans in my upstairs bedrooms. All three are wireless Harbor Breeze ceiling fans. They all have the same issues but at varying levels. issues include:
fan run slower than it should
I measured the house power and I get 118-120v on all three boxes. So I then measured the voltage from the light output(blue wire) on each unit. the readings are as follows:
1st light: 90v - dimness, flickering
2nd light: 103v - slight dimness, flickering
3rd light: 50v - This guy just barely works
All of the wire nuts are tight and they are wired correctly. I have the same ceiling fan in my living room and it doesnt have any issues. I measure the light output on it and it reads 110v which I would expect to be normal.
What would cause this issue with three or four different voltage readings? I cant imagine that I would have three defective ceiling fans. With the house voltage reading normal could there still be an issue else where in the circuit? The last two fans are on the same breaker, but the first one is on its own.
Here is an example of the ceiling fan wiring:
