Topic tags/keywords: doorbell door bell chime diode transformer

Hello,

Recently while my wife and I were out, somebody rang our doorbell and the push button got stuck. This caused our doorbell to overload and stop working, and caused a burning electrical smell.

I replaced the push button (and installed the diode) and also bought a whole new chime unit and installed that.

I cannot get the new unit to work whatsoever. Both units say that a transformer is required, however I could not see one anywhere in the wall.

No breakers are tripped.

- Is it possible that the old unit was installed and worked without a transformer

- Is it possible that the transformer itself fried instead of the chime and it’s just buried in a really stupid place in the wall, would the electrician that built the house have hidden it somewhere weird?

- Should I hook up a new transformer in-line before I cut open the drywall in my foyer looking for the old transformer

- It is a fairly new house (10 yrs) and the wiring has a brown coating (instead of white) does this mean it’s most likely coming from a transformer buried in the wall?

Thanks in advance

Also, could someone tell me how to correctly use a voltage tester? Thanks again

Aw Heck Dave – That stinks!

I wish I could help out but I’m just not an electrician. Sometimes the guys advise me to find a youtube video. They actually help! Maybe you can figure out the voltage meter with a little youtube help.

There’s a big reason I’m not an electrician. I’m terrified of electricity. I’d like to hear that you are safe and sound after the project is completed. Good luck.

More than likely there is a 12v transformer hiding somewhere. Look in the basement, crawl space, attic for a transformer fastened to the side of a light box, junction box, etc. In my area their usually on a metal box.
They are alsmost always on the outside of the box, so don’t bother opening boxes up.
If all else fails have an electrician or a real handy remodeling contractor…... ;^).....hook a circuit tracer to the doorbell button wires and trace it out to find the transformer. I’ve had to do this before.

Yep, our doorbell transformer was hooked directly in to the fuse box. When we replaced the fuse box with breakers, I was too scared to hook it back up (not ‘cause I’m scared of doing wiring, but because: ancient inefficient transformer in the age of switching power supplies) so I got a wireless one.

In my area the transformer is supposed to be within sight of the breaker panel, but sometimes it is on the wall in the room adjacent to where the chime is mounted to the wall (directly on the opposite side) or it can also be found in an entry hall closet, or the garage. Since there are only 3 parts to a hardwired doorbell you can usually find the transformer within a triangle between the button, the breaker panel and where the chime is mounted to the wall.
I think it is important to know what you are looking for—here is a picture, it could be mounted anywhere.

THANK YOU GUYS VERY MUCH!!!!!!!!

After some searching I found the transformer in my cold cellar attached to a box with a light bulb on it. I NEVER would have found it without your help. I will now turn off the breaker and replace the transformer.

Wish me luck! AND THANKS AGAIN!!! YOU GUYS RULE!!

Glad you found it! The guys here at HRF are indeed amazing. So how is the new bell working now? Hope it has kind of a lifting mechanism that lifts its button up after each push to prevent itself from getting stuck when another bell-monster comes visit your house. As for me I use a wireless bell which is idiot-proof and easy to replace.

The problem may lie with the button and not the doorbell itself. Doorbell buttons can easily be damaged by weather conditions and a buildup of dirt. Remove the cover and clean the contacts using either fine grit sandpaper or an emery board. Then, use a screwdriver to pry up the contacts to make the doorbell ring. If the doorbell still does not ring, remove the button, disconnect the wires and touch the ends together. If the doorbell chimes, the problem lies with the button. If the bell does not sound, or sounds very faintly, the bell unit is the problem.
