5 Ways To Fix Doorbell Transformer Voltage Too High

The power input is one of the main things that you have to worry about while trying to install a hard-wired doorbell.

Ideally, the recommended capacity would be mentioned on the box, as well as in the owner’s manual.

You can just look up the specifics for your doorbell and install a transformer to match the power requirements.

If the power flow is not managed, then it can damage your doorbell permanently.

So, you will have to put a bit of focus on the power flow if you wish to avoid extensive errors with the system. 

Recently, many customers have mentioned that they are getting a “Transformer Voltage Too High” warning for their smart doorbell.

This issue can be a bit serious, and you will surely struggle with these errors when the wiring is not managed properly. 

If your mobile application is also showing you a “voltage too high” warning, then here is what you should do to manage your smart device.

How to Fix Doorbell Transformer Voltage Too High?

1. Use Multimeter

Most of the time, users have mentioned that the app may take a bit of time to calibrate with the new transformer.

So, if you are sure that you’ve bought the correct transformer and are still getting the voltage too high warning, then we suggest that you use a multimeter to check the voltage.

According to many users, there will be a variance in the reading recorded by the multimeter and the warning showing up on the application.

If you’re in the same situation and the multimeter is showing you that the voltage is within limits, then you should wait a bit and allow the doorbell to calibrate.

If nothing else is wrong with your transformer, then the error message will disappear after a few hours.

So, if the reading is fine on the multimeter, then we suggest that you leave the doorbell alone for a while and then check the application again after a few hours.

Ideally, the warning won’t be there after the doorbell has been calibrated to the new transformer. However, there have been cases where the reading shown on the multimeter was inaccurate.

Meaning that if you’re using a cheap and off-brand multimeter, then it can show you a false reading.

2. Change Transformer

If you’re not getting an optimal reading with the multimeter and the voltage is actually above the recommended limits, then you need to disconnect the wiring and change the transformer.

It may be that your transformer was faulty, or you bought the wrong kind of transformer for your doorbell.

In any case, if the reading is above the voltage limit mentioned in the manual, then you need to replace your transformer as soon as possible.

Otherwise, the faulty transformer can permanently damage your smart doorbell, and you won’t be able to get it fixed.

Users have also mentioned that a pump in primary voltage can create issues like these for your smart doorbell.

So, if you occasionally experience issues in the primary voltage, then that is likely why you’re getting the high voltage warning in your mobile application.

Even if your transformer is working properly, a bump in primary voltage can increase the voltage output from your transformer. 

So, it would be best if you could use a power stabilizer with your mainline to avoid issues like these.

That way, your smart devices will have a longer life span, and you won’t have to worry about changing them for a few years.

3. Check Wiring Connections

The next thing that you will have to do here is to check up on the wiring. It is a good idea to have your wiring connections serviced at least once every six months.

This basic change will help you avoid a lot of errors down the road, and fixing the unit will come easily to you.

So, when you’re stuck in these errors or can’t seem to figure out a fix, we suggest that you get to the basic adjustment.

That will help you avoid more errors down the road, and fixing the unit will be pretty simple.

So, if you’re still stuck, just call the local experts. They will charge you a bit, but the issue will be addressed in no time with the high voltage.

From there, you can go about using the doorbell accordingly without having to worry about more errors. 

There is simply no gain in trying to save a few bucks and spending hours fixing the doorbell transformer; just be unsuccessful.

Instead, you should focus more on leaving this job to the experts that know how to help you out exactly.

Hopefully, you will not have to go through much hassle when dealing with these points, and fixing the unit will come rather easily to you.

Just engage the experts, explain your situation, and have them check out the system.

You can also ask for a quote first to check if their services are suitable enough for your budget. Hopefully, you will be able to avoid some hassle down the road when it comes to adjusting the system. 

4. Let The Doorbell Adjust

Sometimes, this issue will only present itself for a few minutes, and the voltage will stabilize the system.

If you’ve just installed the doorbell, try power cycling the system and then check up on the response one more time.

In some cases, you will not even have to go through a power cycling routine, and the doorbell will start responding in no time after it has been a few seconds.

After about an hour, you should be able to see that the voltage has stabilized. 

So, it is not that bad of an idea to just wait or power cycle the system.

To power cycle the doorbell, you need to remove all power from the wiring connections or the circuit breaker directly. From there, just keep the doorbell dead for a few moments. 

Once the wiring connections are re-established, you can check up on the voltage error.

Nine times out of ten, the issue will be fixed right here. So, if you can’t seem to address the situation by following through with the basic methods, just wait for the voltage to stabilize. 

However, if the system is not stabilizing even after it has been a couple of hours, then your doorbell might be damaged.

There are no other solutions, and you need to put your focus on getting a new doorbell. So, we suggest that you reach out to an expert and have him guide you through the issue.

Hopefully, that will improve your situation, and you will not have to hassle as much with the system. 

5. Damaged Doorbell

There is also one possibility that your doorbell is damaged, which is why it keeps showing you high-voltage warnings.

So, if the error is still there after changing the transformer and using the multimeter to check the voltage output, then you should reach out to the product support team.

Inform them about the high voltage warning that you keep getting in the mobile application. Depending upon the model of your smart devices, the support will help you with solutions for your specific model.

However, if even the support members can’t help you fix the voltage issue, then you’ll be sure that your doorbell is faulty and you need a new one for your smart home. 

You could claim the warranty on your current doorbell if the purchase was recent. But let’s hope you won’t have to go through with the hassle of replacing your doorbell, and the voltage warning will be a minor bug.

So, if the reading on the multimeter is within the recommended limits, then you don’t have to worry about a thing, and the warning should disappear within a few hours.
