Replaced my doorbell and lost the resistor/doide. Now must how the button until bell stops ringing. What type of and where can I purchase a replacement resistor?

If your Honeywell plug-in doorbell won't stop ringing, there are a few things you can try to troubleshoot the issue:
1. Check the batteries: If your doorbell has batteries, make sure they are properly installed and have enough power. Replace them with new ones if needed.
2. Check the ring options: Press the ring option button with the music sign and cycle through the different ring options until you find one that stops the ringing.
3. Reset the doorbell: To reset the doorbell, unplug it from the wall outlet and wait for a few minutes before plugging it back in. This will allow the doorbell to reset and may solve the issue.
4. Check the chime settings: If your doorbell has multiple chime options, make sure the one that's causing the issue is not selected. You can cycle through the chime options using the settings button.
5. Contact customer support: If none of the above steps work, contact Honeywell customer support for further assistance. They may be able to provide additional troubleshooting steps or offer a replacement if the doorbell is defective.

It is a guess, but wireless doorbells have adjustable frequencies so that your neighbors door bell button doesn't ring yours as well. My guess is that the bell push and the chime unit are mis-matched. Do you have a manual? I can't find one.

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

Open up the back of your bell and the back of your button. There should be switches you can move. Just move them the same on the button and the bell. This will make it so yours doesn't ring when theirs does.

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

Most times, doorbell problems are button, especially since indicator light shows you have power.
Take off front doorbell button and see two wires.
These wires are low voltage and safe to touch.
Use screwdriver and touch both screws together, or remove wires from button and then touch two wires together.
If doorbell rings, then replace button.

If bell still doesn't work then scratch two wires together and look for static-type spark that says wires have power.
If wires have power, and you crossed both wires and bell didn't work, then new door chime is suspect.

If wires do not have power, then transformer is suspect.
Open following link to see example transformer:

Transformers are located in basement or attic.
Scratch a wire across both screws on transformer and look for static-like spark.
If no power, then check circuit breaker.
Home centers sell transformers in the doorbell section. They are 12 and 24 volt. Check markings on old transformer.

If transformer has power, then new door chime is suspect.

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

replace the button switch

it sounds like you have a bad push button . if the wires where crossed you would most likely have this problem as soon as you turned on power . 

What exactly is the cycle? If its a standard doorbell, thats right when you push in it makes contact copleting the circuit. Hence you Get a traditional Ding dong for front door and a ding for a second or rear door. if you release early it breaks the path of low voltage current and does not dong.
With that said is your door bell a custom doorbell, that could change things
