Ring Error Code 5 indicates that your Ring doorbell is not receiving enough voltage from the wired transformer it is connected to. This typically happens when the transformer supplying power to your doorbell is too old, undersized, or failing. Without sufficient voltage, your Ring device cannot operate reliably and may go offline, fail to record, or refuse to charge its internal battery.

How to Fix Error Code 5

  1. Check Your Ring App for Voltage Warnings

  2. Locate Your Existing Doorbell Transformer

    Do not touch any wires or the transformer itself until you have turned off the circuit breaker that powers the doorbell circuit. Use a non-contact voltage tester to confirm power is off before proceeding.

  3. Test the Transformer Output with a Multimeter

    Only test the low-voltage side (the two small screw terminals) of the transformer with your multimeter. Never probe the high-voltage input side unless you are a licensed electrician. Keep hands away from live wiring.

  4. Inspect and Tighten the Doorbell Wiring

    Always turn off the circuit breaker before removing your Ring doorbell or touching any wiring. Confirm power is off with a non-contact voltage tester.

  5. Replace the Doorbell Transformer

    Replacing a doorbell transformer involves working with 120V AC mains wiring on the input side. If you are not comfortable working with household electrical wiring, stop here and hire a licensed electrician. Always confirm the circuit is de-energized with a non-contact voltage tester before touching any wires.

  6. Install a Ring Pro Power Kit (If Applicable)

    Turn off the doorbell circuit breaker before opening the chime box or handling any wiring inside it.

  7. Reboot the Ring Device and Recheck Device Health

When to Call a Professional

If your transformer is located inside your main electrical panel, if the input wiring to the transformer appears damaged or corroded, if you are unfamiliar with 120V AC household wiring, or if you have replaced the transformer and Error Code 5 persists, contact a licensed electrician. Electrical work involving mains voltage carries a risk of shock or fire if done incorrectly. A standard electrician visit to replace a doorbell transformer typically takes under an hour.

Frequently Asked Questions

What voltage does a Ring doorbell require?
Most Ring wired doorbells require between 16 and 24 VAC from the transformer. Ring recommends a transformer rated at a minimum of 16V AC and 30VA. Older homes often have 8V or 10V transformers that are too weak to power a Ring device properly and will trigger Error Code 5.
Can I use my existing doorbell transformer with Ring?
Only if it meets Ring's minimum requirements of 16 VAC and 30VA. You can check the rating label on your existing transformer. If it is rated below 16V or below 30VA, it needs to be replaced with a compatible unit before your Ring doorbell will work reliably.
Why does my Ring doorbell keep going offline after I wired it?
Frequent offline events on a wired Ring doorbell are one of the most common symptoms of Error Code 5 — insufficient transformer voltage. When the doorbell does not receive enough power, it cannot maintain a stable Wi-Fi connection or charge its battery, causing it to drop offline repeatedly. Upgrading your transformer to a 16V AC 30VA or higher model usually resolves this.
Does Ring Error Code 5 mean my Ring doorbell is broken?
No. Error Code 5 is a power supply issue, not a fault with the Ring device itself. In the vast majority of cases, the Ring doorbell is perfectly fine and will work normally once connected to a properly rated transformer. The error simply means the doorbell is not receiving adequate voltage from its power source.
What is the Ring Pro Power Kit and do I need it?
The Ring Pro Power Kit is a small voltage regulator included with Ring Video Doorbell Pro and Pro 2 models. It installs inside your existing chime box and helps ensure steady power delivery to your Ring device. If you own one of these Pro models and never installed the Power Kit, or if it came loose, this can contribute to low-voltage errors. It is a required component for those specific models and should be installed as part of setup.
