Hello

Have a ring doorbell which is powered from the mains using the ring branded transformer that came with the unit.

Its been working well for about 2 months since it was installed by an electrician and then just failed last week and appears as though no power is reaching it.

I used a multi meter to check the transformer and found no power coming out but the input from the consumer unit is reading at 430 volts.


I'm no expert with a multi meter but I expected this to be 240 and I'm now worried its been wired-in incorrectly could anyone advise?

That may be your basic problem. I assume you are actually measuring AC voltage? There are lots of opportunities to select the wrong range on a multimeter.
And this "input from the CU". Is this the voltage measured at the input to the RING transformer, or the output?
 
230v is the nominal standard voltage for single phase domestic supplies so doubt it was 430v.
If you WERE reading 430v between L and N then you would have problems with other equipment and not just a door bell.
Multimeter error!
12-24v is typical for a ring doorbell.
 
430V cannot appear from nowhere without generally destroying most of the electrical equipment in your house. It's likely that your meter is malfunctioning or you are using it incorrectly. Please post pics of the meter set as it was when you were investigating.
