Hanging light dead

marysbobJanuary 26, 2010

Have a hanging light in the kitchen which has 8 25W bulbs. It is controlled from two switches at either end of the kitchen. A bulb blew out today which sometimes happens. The problem is that the entire fixture will not turn on from either switch. (one switch is a dimmer and the other is a normal mercury switch.). If one of the switches is blown will this cause the other not to operate?

Yes, with 3 way switches, both need to function to complete the circuit. If your dimmer is as old as the mercury switch, this sounds like a great chance to replace both of them.

Thanks loads for the info. Replaced dimmer switch. Hanging kitchen light now working! (from both switches).

Dimmers are especially sensitive to the current surges that can accompany a 'blowing' light bulb.

The most common dimmer size is 600 watts, or 5 amps at 120 volts.

Exceeding this number for even a fraction of a 60 Hz cycle can destroy the semiconductor (a Triac) in the dimmer.
