I have a Hampton Bay 3 speed fan. Replaced the switch that was broken but cannot get the speeds to switch correctly. fan will not turn off. and the speeds does not change. I have switched the wires around and the black wire is connected to the L. Not sure what to do next.

SOURCE: Just replaced broken pull 3-speed switch. Fan now

I ran into this when replacing the 3 spd switch. The replacement switch has a pair of connections at each position; you would assume the two connections are electrically tied together, they are not. The switch assembly actually has two seperate 4-position rotary switches. If your "L" wire is on the 'inner' connection, then your motor speed wires will have to be as well.

SOURCE: 3-speed switch replaced with hampton bay switch. Only low speed works.

The cause to the problem was replacing a HUNTER fan switch with a Hampton Bay switch. Before removing the old switch, I noted and marked the color and position of the 4 wires. I then duplicated the connections to the new switch.

But the wire positions of Hampton Bay vs Hunter are not identical, therefore 2 wires
were crossed.

The correct way is to note the color of the wires with the corresponding NUMBER
marked on the switches, then duplicate this on the new one.

Du-uh!
