Is Your Doorbird Offline or Not Getting Power?
A Doorbird video doorbell that will not power on or charge is completely non-functional, leaving a significant gap in your home security. Since Doorbird devices are hardwired, power issues almost always point to a problem with the wiring, the transformer, or the power source itself.
Diagnosing a power issue can seem daunting, but it often comes down to a few common points of failure. This guide will help you systematically troubleshoot why your Doorbird is not charging and what steps you can take to resolve it.
Safety First: Before you begin, please be aware that this process involves working with electrical wiring. If you are not comfortable or experienced in this area, please hire a qualified electrician. Always turn off the power at the circuit breaker before touching any wires.
## Step 1: Check the Power Source (Circuit Breaker)
The simplest explanation is often the right one. Before checking any wiring, locate your home's consumer unit (fuse box) and check if the circuit breaker that powers your doorbell has been tripped. If it has, switch it back on and check if your Doorbird powers up. If it trips again, there is a short circuit somewhere that needs to be investigated by a professional.
## Step 2: Verify the Transformer
Your Doorbird is powered by a low-voltage transformer that steps down your home's mains electricity. These transformers can fail over time.
- Correct Specifications: Ensure the transformer meets the power requirements specified in your Doorbird's installation manual (typically 15V AC and at least 15 VA). An underpowered transformer may not provide enough electricity to charge the device properly.
- Test with a Multimeter: The most reliable way to check the transformer is with a multimeter. Disconnect the wires leading to the Doorbird and test the voltage directly at the transformer's output terminals. If the reading is significantly lower than specified or is zero, the transformer needs to be replaced.
## Step 3: Inspect All Wiring and Connections
A loose or corroded wire is a very common cause of power failure. You need to inspect every connection point between the transformer and the Doorbird unit.
- Check Transformer Wires: Ensure the wires are securely fastened to the terminals on the transformer.
- Inspect Splices: If the wires have been extended, check any splices or junction boxes for loose connections.
- Examine Wires at the Doorbird: Remove the Doorbird from its mounting bracket and check that the wires are securely connected to the terminals on the backplate. Look for any signs of corrosion or breakage.
## Step 4: Bypass the Internal Chime (If Applicable)
If your Doorbird is wired through your home's existing mechanical chime, the chime itself could be the point of failure. To test this, you can temporarily bypass it.
- Turn off the power at the breaker.
- Locate your internal chime box.
- Disconnect the two wires that run through the chime mechanism and connect them directly to each other using a wire nut or connector block.
- Turn the power back on. If the Doorbird now powers up, you have identified an issue with your chime.
If you have gone through all these steps and cannot find the source of the problem, it is highly recommended to contact a professional electrician for assistance.
