I have replaced my doorbell button five times in a year. It is a wired
one, but the light keeps going out. It has a diode in it. The
Westminster chimes sound great.

The third time the light went out, I hired an electrician, and it still
would not light two months later.

The electrician told me to get a doorbell without the little wire inside
the doorbell, called a diode.

Can someone please educate me. From what I am finding out, all wired
doorbells must have a diode or else the doorbell won't chime.

If I really don't need a diode, for a wired doorbell, can someone tell
me that brand and model number of the unit? I am not interested in a
battery operated unit, but surely, there must be a doorbell button out
there that just keeps on working.

This cannot be rocket science.
The electrician I had moved, so I need to start all over again.

Many thanks!

I think your doorbell transformer output voltage is too high. Measure
the output voltage. It should be near 24V AC typical. If it is
noticeably higher you need to replace it or take a measure to drop the
voltage using voltage drop resistor calculated per Ohm's law and
consider using LED. Was it working good and suddenly it is burning
bulbs? Or see if you can find higher voltage rated lamp like 32V.

If she has an electrician in to do a doorbell then I don't think she is
capable of measuring the voltage or other testing. This is not a slam
against her, it's not in her knowledge set.
