How to Repair a dimmer in the home ?

review probable causes

So, first of all let's talk about what was the "culprit" malfunction of the dimmer.

Most often, the dimmer stops working after a blown bulb in the chandelier or lamp.The burnout time may be short-circuited, causing burns one of the most important elements in the dimmer circuit - triac.If not running triac, it breaks down the whole scheme.

The second reason why the device can not be activated or vice versa - do not turn off the light is that svetoreglyator works with energy-saving lamp.We have been told that you need to buy special dimmers for LED and fluorescent lamps, just designed to work with the "housekeeper."At the same time it is necessary to select special dimmable LED bulbs, rather than the usual.If you have not considered this requirement, the problem is precisely this reason that clearly shown in the video example.

Another likely cause of the problem - wrongly selected power dimmer as a result it does not work as it should.We have repeatedly said that the dimmer capacity should be 30-50% more than the power of all the bulbs, which it regulates.If you missed this point and inserted into a luminaire too powerful light sources, not strange that the dimmer does not switch off the light or do not adjust the brightness of the lamps.Well, the last thing to say - perhaps a problem in the wiring at the site: a chandelier-breaker.

How to fix the damage?

Now proceed as follows: - look at the main fault dimmers and immediately give advice on repair their own hands.

If the device does not turn on the light, first check the fuse mounted under the decorative cover.When voltage drops it can burn, protecting the rest of the circuit elements from failure.Replace the fuse will not be difficult, especially since the leading manufacturers of dimmers (Schneider, Legrand) complete investing spare fuse, as shown in the photo below.

When the dimmer does not regulate the brightness of the lighting is not switched off and not switched on after a blown light bulb in the lamp, it is necessary to switch to a more serious repair, becausemost likely, it does not work triac - fired a short-circuit.This circuit element can try to replace their own, it requires a soldering iron and thus skills with these tools.You may also need a drill with a thin drill (hereinafter explain why).To be able to unsolder punched triac and solder a new one, you need to remove the aluminum radiator with the board, which soon mounted rivet.You need to carefully drill out the rivet, then unsolder himself triac and install exactly the same, but a whole.For all of these cases we recommend to use a homemade mini drill and homemade soldering.

If you use a dimmer switch to conventional energy-saving lamps, we recommend how to change the lamp as soon as possible to special becauseYou can not use inappropriate housekeeper.

And finally - if not only the dimmer does not work, but a normal push button does not turn on the light, then the problem is in the wiring itself.Perhaps somewhere whiling away the wire, and perhaps the problem is the fault itself chandeliers.There is already a need to take a multimeter and prozvanivat all regions of the chain.

Here, in fact, all of the major causes of failure.We hope that now you know why the dimmer does not work and, most importantly - how to repair their own hands dimmer!Finally I would like to note that these devices are very sensitive and because of the existing problems with voltage drops their use is not recommended without stabilizers!
