About 12 years ago, I bought remotes for two of my fans. They died about 6 months ago, about a month apart. A couple of days ago, I bought a Hampton Bay 191-691 remote control system. My original remotes are no longer manufactured. It is simple. Black and white going into the remote and black (motor), white (common) and blue (light) coming out. I wired the thing in, set the DIP switches, put a brand new battery in the remote, turned on the fan and - nothing. I pulled all of the chains fruitlessly. So I hooked the remote up to my multitester. I expected to see a voltage drop when I keyed the remote. Nada. It was a steady 110, which seemed strange since the fan didn't appear to be getting juice. So I bought an identical remote and tried again. Nothing. I called the company, but they were clueless (can't blame them). I thought that maybe my house wiring was wrong, so I checked it. Black is positive and white is ground. I checked the fan wiring. It is correct. So I hard wired the fan in. It is running like a charm right now. Funny thing. When I was playing with the remote, I got a mild shock. This is funny because the power to the whole house was off at the time. Oh, another funny thing. When I installed the second remote, the light worked fine. It dimmed and shut off on command. Then I switched the battery to the other remote to check it, the light wouldn't light. When I put the battery back into the original remote, the light wouldn't light. I now have remote #3, but I'm reluctant to wire it in until I get some other thoughts. Thanks.
