delay light after flipping switch


Installed a ceiling fan/light. the fan comes on when I flip its switch. The light comes on after a short (1 sec) delay when the switch is turned on. the light that was there before did not delay at all.

Is it a CFL lamp? I have seen some brands that for some reason have a delay when turned on.

There's a loose wire up there. More than likely with the light fixture.

Shut off the power to that circuit.

Test with certified voltage tester for this purpose. Be sure all power is off on the circuit. Wear safety glasses. Rubber-palmed gloves.

Remove the entire unit. Very likely, whoever did the set up, has something loose in the wiring. Remove all the caps. Anything that's loose should be tightened....something is loose. Take your time about it.

Theory is that the fan is correctly hooked up, but there's something loose with the light fixture entity. So, the vibration of the rotation of the fan, is what momentarily moves the disconnected wire(s) of the light to contact.

More than likely your light fixture connection is loose [wires specifically]. Please, don't facilitate any electrical fire hazards, ok? Tighten the loose ends. Tighten everything ... since the wires to the light fixture may also be barely touching.http://hgrbservices.com

What are the rubber palmed gloves for?

No. I think there is a loose connection, just hated to take the thing all apart.

Be certain all the power in this circuit is off. Use a certified voltage tester to confirm. Wear rubber-palmed gloves and safety glasses (you may have to look higher). Check the light switch for loose ends. Is all the copper of each wire inserted snug around the terminal screws or in the switch?

See any broken, loose, or disconnected wires?

More than likely, if you don't see it, you've either got too many things using that circuit [especially if you've added a new appliance], or you need a new light switch.

If you've recently installed the switch, and nothing is broken or lose around it, very likely the light switch is defective. Replace it.

delay light after flipping switch


Is the time delay always the same length?

If you substitute a different lamp (if one fits), is the delay different (no delay for an incandescent)?

Does the light flicker?

I would not be surprised if there is a built in delay for the lights so the fan motor is allowed to get up to speed whereby its power draw drops, prior to switching on the light using internal circuitry. But this is added complexity and expense so I would not expect this.

Does one switch control both the light and the fan or are there two switches?

Did this fan kit come with it's own remote kit? Are they CFLs or incandescent? Do they come to full brightness instantly or gradually increase to full brightness?

The light on the fan I put in my bedroom came with it's own remote and incandescent bulbs. When the lights are turned on, they gradually increase up to full brightness, controlled by the receiver module.

If there is a capacitor associated with the fan circuit, this could be causing your problem,
disconnect the fan and see.
When first turned on, a capacitor is almost a short circuit,
until it charges up, this usually only takes a second or so.
So until the cap charges up, all the power is going into the charge
process, leaving not enough for the lamp.

Please be advised that many ceiling fans now incorporate a current-limiting device in them to prevent the use of too-large light bulbs in their light kits.

This can cause a slight delay in the light working once power is applied.

Normal operation, no testing or repairs are needed.

So, no need for rubber-palmed gloves?

I put in two Hunter fans last year.

They both do exactly the same thing (standard bulbs).

It's part of the light kit. Curiously, the fan will not operate without the light kit.
