What Would Make a New Light Bulb Keep Blowing out in a Kitchen Exhaust Fan?
Light bulbs may burn out too fast because they are screwed in too tightly. Each light bulb should be screwed in to a point at which its tip touches a tiny filament that conducts electricity, sending it into the bulb. When the bulb is screwed in too hard, this small piece of metal is bent back to a point where it does not return to its normal position. The impact is a small electrical arc that creates extreme heat and begins to melt the soldering.
