Door bell not functioning

Hello, I have a hard wired video pro door bell which was working perfectly fine for last 2+ years and unfortunately it stopped working - I suspect two things, either faulty transformer or faulty ring door bell. How can I measure the current on transformer using a multimeter and what reading should I expect? If someone can advise the settings on the MM, I’d appreciate it. Also, this is how my device looks like now. Is it possible it could be faulty?

Hi @todaymorning04. Try resetting the Doorbell by holding down the setup button for 20 seconds. If that doesn’t work, and the Doorbell is still unresponsive, it may be a power issue. You can consult a qualified electrician to check the transformer. If the transformer and wiring seem fine, then I’d recommend reaching out to our support team at one of the numbers available here.
