The light bulb used to illuminate the chamber cooler, works in specific mode - in the cold. And as you know, the bulb always burns in the moment of inclusion, as its filament is cold has small resistance. When you turn through this thread flows increased current and destroys the filament bulbs.
In the chamber of the refrigerator light bulb lighting is at a lower temperature than the room. Therefore, the probability of failure of bulbs even more.
I propose to supply power to the light bulb through the diode. And although the light bulb when it blinks with a frequency of 50 Hz, this does not prevent. I put this diode CD 2 more years ago, and none of the light bulb is not out of order. And previously had to change the bulb often. Insert the diode CD very simple.
In the refrigerator the light bulb stands in a socket of type "minion", inside of which quite fits diode CD, as it has small. Do as follows. Remove the cartridge Mignon, first disable it from the network, to put the diode. The diode pre-accusive conclusions, leaving small tips for what you have! wires to them. Solder wire, turn on the diode in the gap of one lead wire in series with the light bulb.
Connect lead wires. Further, the cartridge is put back in place and screwed the light bulb is. Everything is ready.
Diode CD quite resistant strain, as the light bulb in the fridge capacity of only 15 watts.
