How to Upgrade Doorbell Transformer

Check out our HOW TO video and DEMO of installing and upgrading a video doorbell transformer! If you are having any issues with your ring doorbell transformer, nest doorbell transformer, eufy doorbell transformer, then it may need to be replaced. You may also experience issues such as doorbell not working, short chimes, or the video doorbell is indicating that it is under powered. These can all be reasons for needing to upgrade your doorbell transformer. Do it yourself and watch this video of how to upgrade easily. Most newer video doorbells require 16-24v transformers and older homes can have much smaller transformers. You can purchase a replacement doorbell transformer at The Home Depot and Walmart, but we purchased on Amazon.

This video is great! I am a 67 year old woman who lives alone and I wanted to install a video doorbell, but my current transformer did not have enough voltage. Your instructions made it so easy to upgrade the transformer by myself. Thank you for making such a detailed video.

[@TwoNerdEFamilies]

@Laura Marchesani, thank you for sharing your feedback and so glad that you found this video helpful!

[@Review1NFO]

You have no idea how helpful your video was. I was getting frustrated why my new doorbell camra wasn't working.

[@TwoNerdEFamilies]

So glad to hear this helped you. Thank you for the comment and for checking out our video!

[@jonbrown6316]

We ended up exchanging this model for the slimmer version kzbin.infoUgkx0jZ_lGlDVJhDnmagEU8gn47cmfPNlLQU because it was too wide for the only door trim area that made sense to mount it on. However, we should have just noted the dimensions prior to purchasing. Otherwise, we love the doorbell. It works perfectly, and the video is very clear, even at night.

[@Anythingwheels]

I had an issue when I first installed my Eufy doorbell as it wouldn't even power up. After finding your video and ordering the transformer via amazon and switching out the old one, my Eufy doorbell is now working and it was all because of this video!!!! I am so grateful for you taking the time to create such an easy to follow instructional video. My friend paid someone $300 just have their video doorbell install so you also saved me some money too!

[@TwoNerdEFamilies]

@Chase Morgan thank you so much for checking out our video and leaving these kind comments. We're very happy to hear that this video not only helped accomplish the task, but also saved you money as well!

[@waheedkhan3505]

Chase Morgan did your existing chime start to work as well or was it just needed to power the bell

[@BLJTheGeneral]

I am in no shape or form an electrician but this video made it easy for me to swap out my transformer for my video doorbell. I had a 12V transformer before and this allowed me to upgrade to 16-24V transformer. ADT was very happy with the upgrade to install my new security system.

[@jewdd1989]

Super helpful!!! I’ve had the nest doorbell and when purchasing it at Home Depot I was informed my transformer was probably old and I’d need to update it. Long story short I went the battery route and one day when charging the battery someone stole a large, pink rock my grandmother had given me out front during broad day light but I didn’t have the damn footage so I want it hardwired. This was super helpful, I haven’t done it yet but simple, clear and useful instructions so thank you

[@canyavotsaba]

Excellent video! I searched many websites that provided insufficient or confusing information about this issue and none even remotely compared to the clarity and straightforward instruction that you have. Thank you very much!!!

[@TwoNerdEFamilies]

Thank you so much for the kind words and glad it helped!

[@Samlol23_drrich]

Very interesting to me because around here in NY the transformer is almost always located on the breaker box, or within a foot or two of it, and then low voltage wire is run to the bell. Thanks for showing me this. Learned where to look if I can’t find it!

[@TwoNerdEFamilies]

Yes, lots of different locations depending on regional trends and also ever building and contractor will do it a little differently, so sometimes you just have to look around if not finding it at first.

[@leeferenc]

Appreciate the straight forward video. Was able to locate the transformer and swap it it out with a larger voltage transformer to power the new doorbell.

[@grantgoodman1533]

No one else doing doorbell videos spoke about where the transformers were or could be, so we can't fix it if we don't know where they are. Thanks for answering that very important question!

[@jasonmconnors]

After searching all over with no luck, I found mine attached to a floor joist in the crawlspace underneath my 70 year-old house.

[@TwoNerdEFamilies]

Glad it helped! Thanks for checking out our video and for leaving us a comment!

[@TwoNerdEFamilies]

They can be just about anywhere depending on the age of the home. We've heard of them being above in the attic and in utility rooms on a different floor. Glad you were able to locate yours. Thanks for checking out our video and for leaving us a comment!

[@jessemcdonald9119]

Good video. The only thing I’d say is though some of the older houses have the transformers in the box, code is to have the transformer mounted on the outside of the junction box as they get hot and present a fire hazard. Just be careful and safe guys.

[@soldatheero]

even if the inside wall has insulation in it? is it okay to install it on outside of box as I want to in an exterior wall

[@TheeJoeyPage]

Bro I just asked my boss for help and he said KZbin it my transformer has three screws and the two low voltage wires look the same any advice

Excellent. Wish you talked more about the button and bell wire configuration too. Most transformers are found in the furnace room not behind the bell.

[@TwoNerdEFamilies]

All good points, thx. We've noticed many comments since posting the video that indicate the many locations people are finding their transformers, so hopefully that gives folks some other ideas if they're not finding it right away. Thanks for the feedback and for checking out our video!

[@howie4150]

On the west coast. Most transformers are located inside a closet of a bedroom or coat closet and is usually located closest to the chime or doorbell that goes ding dong.. On really older homes. They installed it inside the attic which is a terrible place to find and service it.

[@saadatsabur6748]

Hi many thanks for the easy to follow explanation. Would this method work for a house in the UK? Also I know you tweaked the voltage with the transformer. What about the current.

[@SmoothBassVO]

Great video! I measured the voltage at my current bell button as 18V. Should I be OK from an amperage standpoint? Also, there is an unused green wire at my current button. Does that get used by Ring?

[@danielgomes4754]

Very Good information. Thanks!

[@macristo33]

I think I need to do this. I had my Ring Doorbell Pro 2 professionally installed a year ago. About nine months later it stopped working. I called support twice which was a waste of time. My house is new and the current transformer is 16 volt. My Ring app indicated it was not getting power, so I came to the conclusion that I need the 24 volt transformer. This video should resolve my Ring doorbell issue. I hope!

[@MM-fe9mz]

Also should have mentioned there's a difference between a 16v 10va and a 16v 30va transformer. Many times need the 30va if you want both the video doorbell and the mechanical chime to work at the same time.

[@gomo63108]

Fantastic instruction!

Great video, bought a Eufy video doorbell with it's own chime,my house was left wired for doorbell if I choose. I have a no original chime can I wire straight into a new transformer to reduce from 230v and then connect all the wires.

[@tthoy7338]

Good clear presentation 👍

[@anthonykhow]

Thanks for the video, it was very informative. What do you do if your old transformer only has two wires not three?

[@arizonakaren]

I have the same issue.

[@rosarodriguez-wm3qj]

Hi & thanks for your video. I do have a question. I was advised by Ring customer service that the transformer should not be placed within the walls because it can cause a fire. I expressed that the old doorbell, like the one you showed is already inside the wall. All I'm doing is switching out the old transformer with new. Your thoughts?

[@henry.sanchez]

Thank you! You just saved me $100+

[@TwoNerdEFamilies]

[@romang8396]

Good job man thanks for the infor

[@yingzhu7978]

Very nice and concise video. Thank you! One question regarding your eufy doorbell, how did you mount it to your siding? Thank you!

[@TwoNerdEFamilies]

Thank you for your feedback and question. The doorbell comes with a bracket and screws, so I just tucked it under one of the strips below where the siding flares out so it was mounted closer to the wood behind the siding which allowed it to securely mount without pulling the siding in or cracking it. If your siding is like mine in shape and size, you don't want to go too tight on the lower screw when doing this as it starts to flare out again towards the bottom of the section you mount it too and you don't want to damage the siding. It still feels very secure, but you can also try notching out the siding with a multi-tool and mount the bracket directly to the OSB wood sheeting behind the siding if that's the type of home you have. Good luck and thanks again for checking out our video!

[@jefe8118]

Thanks for the video! Is there a scenario where you may have to replace the chimebox in addition to the transformer to prevent any burnouts/ fire issues? TIA...

[@adrenaline112]

Good stuff 👏

[@MyTabooLyfe]

It’s crazy because my home was built this year and it’s buzzing after I just installed the ring video doorbell pro 2 yesterday.

[@williamwells1015]

Great video step by step explained. I have a question: my transformer is in a different room from the chime. I changed it out in accordance with the video and my experience. It is not charging the ring. Any thoughts?

[@TwoNerdEFamilies]

Thanks for watching our video and for posting your question. I would take a volt meter and just test that you're getting the proper voltage to the wires connecting to the doorbell. If no voltage reading then there may be a problem with the wiring and low voltage is sometimes caused when the wire is too long of a run for the voltage to carry strong enough to the other end. You may want to install the transformer closer in that case. If voltage is fine then it might be an issue with the doorbell itself and I would contact Ring about next steps to replace the unit. Best of luck!

[@Ironboost007]

thanks for the vid! question: by changing the transformer, would I also need to ensure I have a chime compatible with the 16-24v transformer? or does any one work

[@warweaponx6629]

Great video. Unfortunately my transformer isn’t behind my chime. If you connect the Ring and it powers up can you assume your transformer is sufficient?

[@reshamvinayak]

Very well explained. Thanks. Just a quick question - the video doorbell is infact a replacement for the ringer ? The old ringer is to be replaced with it ? And then it is set up to connect with wifi.... right ? I couldn't find any video that guides well into the connecting a video doorbell as a replacement to the old fashioned bells. Thanks.

[@TwoNerdEFamilies]

@Tony Hwang seems like that one meets all of the requirements so don't think you'll run into any power issues. Thanks for checking out our video!

[@NunyaBusinessEither]

Great video. My problem is, my current doorbell chime doesn't have a transformer like yours does. Would you know if there's a way to hardwire a Ring Chime? I'm not a fan of having it plugged into an outlet.

[@brianburns1483]

Great informative video. Can you do video on why the will randomly chime continuously without no touch the door bell and how to fix that issue?

[@sandywjo5]

If you ever decided to get rid of the doorbell camera and go back to old regular doorbell button, would that old button also work with the newer higher voltage transformer you just put in?

[@GoldenBabbler]

Thank you for a great video! I am having an issue because my existing doorbell transformer is next to the circuit breaker and it's an older model with only 2 wires (no ground) while the new transformer sent by Ring has 3 wires (with a ground). How do you recommend I install this?

[@sfnative3200]

Thanks so much! Very helpful -I have an Arlo and it wasn’t working because the transformer in our 1961 home is only 10 v 16 V. Question: I Purchased a stronger transformer this week that is 16 V to 30 v And advertised but it’s compatible with Ring Cetera. There are other things attached to the 10 v to 16 v older transformer. Do I just replace it with a new transformer or should I tone the door bell wires out and give it its own 16 v to 30 v transformer?

[@TwoNerdEFamilies]

Sorry for the delayed response. It depends on what else is connected and if that will be enough total voltage to supply to everything. Some homes have multiple chimes or doorbells for different entrances. One transformer would be enough if running a video doorbell and an older analog doorbell for example, but running two or three video doorbells may require a more powerful or separate transformers in order to supply enough voltage to everything. Hope that helps!

[@MustahB]

Nice "nuts and bolts" video! Have an identical chime. Initially by-passed the chime to power a Ring wired doorbell 2021, but wondering if upgrading to a 24V transformer would power both? Being limited to the ring app or having to buy their dedicated chime is not preferred. Would very much appreciate your thoughts. Thx!

[@chris23384]

great video thank you for sharing

[@TwoNerdEFamilies]

Thanks for watching!

[@garymarkarian7838]

My current chime in my house is being operated with a 5 volt transformer. I need to change it out for a 16 volt transformer to operate a Ring Pro that I want to install. I'm concerned that a 16 volt transformer will burn out the 5 volt chime that I currently have in my house. So my question is, if my current chime is operating on a 5 volt transformer, won't a 16volt or 24 volt transformer burn out that 5 volt chime ? Or do i need to upgrade the chime also ?

[@helsan74]

Did you got an answer to your question? What voltage transformer did you use? Thanks

[@StevenDanielZigila]

Bump

[@Thebooniefrog1985]

Chime can remain, it just completes the low voltage circuit. The transformer needs to be upgraded to the 16v. If not it will definitely burn out the 5v transformer & your ring receiver.

[@Italiandogs]

Do i need to replace the low voltage wiring to the doorbell if I get a bigger transformer? Rn my transformer is 10v and I'm seeing 13v on the voltmeter

[@superkidgamer4551]

you are so lucky that your transformer is in a box behind the doorbell. That makes sense. Mine is somewhere else in the house and I have been looking for it for weeks now. The low voltage wires run down the wall and through a stud. I feel like I have looked every logical place this transformer could have been put. It is a good video, though

[@TwoNerdEFamilies]

Sorry to hear about the trouble locating the transformer. Reviewing the comments on this video, seems others have found the transformer in a myriad of places. I'm sure you've checked in the utility room near or in the breaker box? Some have found it in the attic above the wall where the chime is installed, but sounds like your low voltage wires are running downward. Definitely sounds like a tricky one. I've had similar trouble tracking down other wires in the past and purchased a cheap $30 snake scope / inspection camera to help track things down so I didn't have to open up walls or ceilings to explore further. Best of luck to you and thanks for checking out our video.

[@stevebailey997]

I’m having a problem with the voltage same as described in the video, can you buy a complete chime box with an integrated 24v transformer. I’m living in the U.K. any suggestions would certainly be appreciated, Excellent video 👍🇺🇸🇬🇧

[@TwoNerdEFamilies]

Not sure what's available in the UK, but there are a lot of chime/transformer 'kits' available on Amazon and at local home improvement stores here in the US. Here's an example (link below) of one that I couldn't see the va (volt-ampre) rating for, but comments indicate that it works with Ring video doorbells. Try to find a kit with a transformer rated within the range specified by the manufacturer of whichever doorbell you're installing. Most of them these days require a 16-24v / 30va transformer. amz.run/3yBd

My Eufy wired 2K camera works fine except for 2 way audio. I measured a transformer in the garage and it's 17.9V but I also have a chime which I haven't the measurement of that transformer yet. I've been having issues of 2 way audio. The doorbell broadcasts audio out fine but I can't hear from the other end (delivery person). Did you encounter similar problems?

[@TwoNerdEFamilies]

Haven't run into that issue here. How is the WiFi signal strength from the doorbell? I believe you can see the status in the app. I'd also try contacting Eufy support to see what they suggest on that one.

[@pearlperlitavenegas2023]

Can you keep your existing chime? With the Eufy? Which model is it? I guess not. I don't have a chime just a transformer. Do I need a chime on the wall for this to work?

[@archaedia]

Hi there, I have two doorbell chimes attached to regular doorbell buttons (not camera or anything like that), they are attached to one transformer which is attached to the breaker box. The old transformer was 16v 10va, would I be okay to replace it with a 16v 30va?

[@OutofDarkness_jik]

Thanks for this video! If you are a renter and you install the 16V transformer to be able to use a video doorbell, but then you want to take your video doorbell with you when you end the lease, will the 16V transformer be too much for the existing doorbell that was on the older transformer? or would it be safe enough? Thank you.

[@olioli7652]

I love it

[@thesonofdarwin2717]

Any issue installing this transformer on a 20A circuit vs 15A? We have easy access to a 20A near our existing doorbell wiring.
