When someone rings my doorbell they can't hear me and I can't hear them. It worked at one time.

it is possible that the doorbell button is sticking down and keeping contact - so the doorbell keeps chiming.

We had a similar problem with a wired doorbell. There is a diode in the doorbell itself that causes the chime to ring fully. If the diode is backwards, you get just a small tone and can only hear the full chime if you hold the button down. If this sounds like your problem, open up the doorbell at the button end (or have an electrician do it) and reverse the diode.

Hi

To fix the issue you need to remove the batterys from both the bell push and the bell unit for 10 mins, then replace the batterys and then push the bell push so it can switch channels and be different from the house down the road

need more info. Doorbells do not need 2 xfrms. The red off 24 volt xfmr foes to door switch and returns on white. If you have 2 door switch one switch to front door label on doorbell and the 2nd goes to back door label. What is the brand and model number/ I'll try and walk you thru it.

99% of the time, you need a new doorbell button
Also check if any circuit breakers are tripped
Check GFI breakers in baths and kitchen

Real-estate lady answer: buy a new doorbell button and connect 2 wires on back of new button.
Doorbells are low voltage and not dangerous.
If screws are loose in the holes, break off toothpicks in hole so screws have something to bite.
You need small screwdriver:


Repairman answer
Doorbell problems have 3 parts
1) The button
2) The chime or bell located in house
3) The 12V or 24V transformer located in attic or basement
4) rarely the wiring because it's low voltage and does not get hot

1) start at the button.
Remove button from wall
There are two LOW-voltage wires on back of button
Remove 1 wire and touch other wire, copper to copper
Does doorbell ring? Do you see a spark?
If bell rings, then button is bad

2) Chime or bell doesn't ring when button wires are crossed
Take cover off chime
The button works, so have helper push button while you're looking at chime
Can you hear any noise? Have helper push button on-and-off
Chimes have 2 or 3 wires >>> 2 wires if only front door has button, 3 wires if back door also has button
Take one wire loose and scratch it across each of the other wires
Remember front button is held down (or front button wires are twisted together)
Can you see a spark when wires are scratched together?
Try this with more than one wire ... but don't mix up location of each wire
If you are getting a spark, then chime is getting power, but it's not working
Replace chime

3) Transformer in attic or basement looks similar to this:

Use a wire and scratch across both screws to see if you get a spark
If you get a spark ... and the crossed wires dont ring the chime... and there is no spark at chime, then there is a bad wire
If no spark at transformer, then check circuit breaker
At last resort, but new transformer at Home depot in the doorbell section near light department

Start here

Locate and check the doorbell system transformer for power. There should be about 24 volts A/C on the secondary side (the side with the smaller exposed wires that go to your doorbell).

The doorbells at the doors are just switches and it sounds like you have already tested them correctly by touching the wires together.

It sounds like a power issue - your electrician may have just disonnected the power wiring after installing the wireless system which would have been the right thing to do.

Batteries are located in the doorbell push button case in the back. Slide open a compartment to reveal the batteries.

Yes, there is a way to change the security code. See FAQ here:

click on "how can I change the security code."

The cadence is different, but you can change all the other rings to a different tone. On a 76xx phone, press PROG and the CO button twice. Press your navigator button up (or down) until you hear the tone you like, then press enter to save.

Tones 01,04 and 05 tend to be reasonable.
