Ceiling fan & lights turn on automatically


I couldn't find someone with the same problem so here goes:

I've replaced a ceiling fan (the old one had some parts missing), but as soon as I put the power back, the light and fan turn themselves on even when the light switch on the wall is off. Playing with the light switch (on and off and on and off) does nothing either. They respond when I pull their chains, though.

The new fan is a canarm Neptune 42" with no remote (product page: http://www.canarm.com/Residential/Ceiling_Fans/CeilingFans/42/CF42NEP4BN)

I have two wires coming out of the ceiling outlet: a black and a white I have four wires from the fan: green, white, black and blue

I shut off the power (breaker off) and then, as per instructions in the manual, I left the green (ground) by itself, connected the two white wires, connected the two black wires together then added the blue to the connection. As soon as I restored the power (aka put the breaker on), the light and fan were on and not...

Do you hate coming home to a dark house, or a house with no outside lights on? Sure you do. Wouldn’t it be nice to have the lights turn on right before you pull up? You bet it would. This would make it easier and safer to walk from your car to your house, and also less frustrating to unlock your front door. You can install different fixtures that have built in timers, motion sensors, or darkness sensors, but this can be an expensive task that is beyond the technical ability of most folks. You could also replace light switches in your home with fancy timers and digital switches, but once again, this can be very expensive, and quite possibly, more suited for a professional electrician. Beyond that, many homes are not able to be retrofitted with these devices, so they would require a much more expensive rewire and replacement. There is an easier and less expensive way to have lights turn on automatically, and it is a device that anyone can install in just seconds. Of course,...

Sounds like you're getting interferrence with the wireless control module. You can remove the shroud at the fan and try another setting on the remote control module. Just be sure to set the wireless hand-held control to the same settings in order for it to operate properly.

Please refer to your owners manual for the fan and the wireless controller for any questions on how to set them to work together. You may have to try a couple of different settings until you get one that isn't
affected by the interferrence it is presently receiving from another ireless source.

Those sources could be a garage door opener, wireless doorbell, TV or other remote control. Cell phones, walkie talkies, and so on. Almost anything that produces a radio signal, could be the cause of the problem.

Hope you found this very helpful and best regards!

This thermostat ceiling fan and light remote control automatically turns your fan on and off and sets the fan speed based on room temperature, conserving energy. Three fan speeds (high/medium/low) and a full-range light dimmer offer customization and increased savings on your utility bill. The convenient timers allow you to separately set the fan and light to run anywhere from 30 minutes to 24 hours each, so you don't have to worry about forgetting to turn them off and wasting energy. For additional assurance, a room-exit feature turns the light off three minutes after you leave the room. Once you wire the receiver to the fan in the ceiling, the remote control communicates wirelessly with the fan up to a distance of 40-feet. The receiver (fits most fans) and the remote uses four AAA batteries (included). CUL US-listed, and compatible with most ceiling fan brands, this remote can handle a fan maximum of 1-1/4 amps and a light maximum of 300...

Now when I walk into my room (or my cat :) my lights automatically pop on for me! In this project I'm going to show you how to for under $5 hook up a motion sensor to you ceiling fixture! This is what happens. When the motion sensor senses motion it sends a HIGH signal to microcontroller. The microcontroller then turns on the light and starts a 5 minute countdown. Everytime the motion sensor senses motion it resets the 5 minute timer. So say I walk in my room at 5:30 and immediately walk out. At 5:35 the light will turn off. Later in the day my cat walks in at 6:00, then walks out. Three minutes later, she sees a mouse in my room, so she runs back in at 6:03, but realizing that the mouse if just a play mouse, runs back out. At 6:03 The timer is reset and the light won't go off for another 5 minutes (6:08).
The second mode of this project just keeps the light on as long as the circuit has power. So if you sleeping at night and want the fan to stay on all night you can switch it...

If this happened to me, I'd just rip out the remote receiver and hard-wire the fan. I'd assume that the receiver was just stupid and indiscriminate, and would trigger on nearly any RF on or near its frequency.

Ever read the user or installation manual for wireless gadgets? You'll always find something like this: "This device may not cause interference, and must accept interference, including interference that may cause undesired operation of the device."

It used to be that if you were generating radio transmissions, you had to have an FCC license unless the power was tiny and the frequency was within certain specific bands. Then the Commission started granting license-free waivers to all kinds of products in the name of consumer convenience. The conditions for such a waiver include printing the disclaimer above in the manual and/or on the gadget.

In other words, you have the right to use your remote control, but no right to any kind of protection if someone...

Hey there Lisapisa7, I’m Blake from Home Depot out here in California. I ran into the same problem when moving into a new place out here. There are basically two reasons you may be having problems with your lights. The first (and easiest to fix) is simple RF interference. It is possible that some other device that uses radio frequency is talking to your fan on accident.

The fix for this is to change the frequency that your fan listens to.

-Open up your remote control battery compartment and locate the set of dip-switches

-Change the switches around (it doesn’t matter what you set them to, only that your receiver matches)

-The next step is to turn off your circuit breaker that powers the fan (just in case. You will not need to do any wiring for this fix)

- Test that the power to the fan is dead using a voltage detector

-Drop the canopy by removing the screw cover and unscrewing it from the mounting bracket

-Pull out...

Is your Hampton Bay ceiling fan turning on and off by itself? Or, you might have another brand of ceiling fan that is doing this. This can be happening because of the frequency on your fan is set to the same frequency as someone else’s close to your home. For instance, your neighbour could have a different ceiling fan than yours, but the frequency may be the same on the remote. Your remote has to be set to the same frequency as your fan.

Fan and remote frequencies are set to one another using dip switches. The first thing you should change when you start to have problems with your fan doing things on its own, is change the batteries in the remote. The batteries could be low and the fan might not be functioning properly.

If you have some batteries in the home, check for them and try switching the batteries first.

The next thing you should check is the dip switches on the remote as well as the fan. Try changing the dip switches. You can find the dip switches on...

Ceiling light turns off 2 seconds after being turned on

I just purchased a brand new house, closed on it today and went to take a look at the place again this evening before we move in. Upon leaving I discovered that the ceiling light/fan in the living room will turn off by itself right after I turn it on. It's just the light part, not the fan. It has 3 of those flame-shaped bulbs, they all do the same thing. The light has two switches on different sides of the room, and the same thing happens with either switch and in any combination of the two switches being on or off. I haven't messed with changing the bulbs out yet because I didn't have the tools with me to take the fixture apart to get to them at the time. Anyone know what could cause something like this? I'm hoping it's just me being stupid or something simple I can fix myself, although the place comes with a home warranty so if it comes to it I could call the builder.

brand new house, call the builder. could...

Just for kicks, what happens if you unscrew one (or unscrew two) of the bulbs.

The way modern dimmers operate (by altering the waveform of alternating current to be different from a smooth sine wave), bulb filaments can buzz at certain brightnesses corresponding to certain waveforms.

What is the wattage rating for the dimmer switch?

House destroyed by fire? Flood? Windstorm? Seriously consider selling the property and moving. Fixing, er, rebuilding, the house will become a money pit, er, time pit having to find, line up, and watchdog contractors (and also stays a money pit).
