When your Blink Doorbell starts blinking red and blue, it can be confusing and worrying. Most people expect their smart doorbell to work smoothly, but these lights mean something important is happening. If you are seeing these blinking colors, you’re not alone. Thousands of Blink users face similar issues every year. Understanding what these lights mean, how to fix them, and how to prevent future problems will help you feel more confident with your device. This guide explains everything you need to know, using simple English, practical advice, and real-world examples.
What Do The Red And Blue Lights Mean?
Smart devices like the Blink Doorbell use lights to show their status. The red light and blue light are not just random—they have clear meanings. Let’s break down what each color means and why your doorbell shows them.
Red Light
A blinking red light usually means a problem. Some common reasons are:
- Low battery
- Wi-Fi connection lost
- Device setup not finished
- Firmware update needed
The red light tells you the doorbell needs your attention. If ignored, your device may stop working, miss alerts, or not record video.
Blue Light
A blinking blue light is less serious. It usually means:
- Device is recording
- Motion detected
- Doorbell button pressed
Sometimes, the blue light blinks when the device is updating or restarting. It’s often normal but can signal setup or connection activity.
Red And Blue Together
If your Blink Doorbell blinks both red and blue, it usually means:
- Device is trying to connect to Wi-Fi
- Setup mode is active
- Firmware update in progress
This combination is common during installation or troubleshooting. If it continues for more than a few minutes, something may be wrong.
Common Causes For Blink Doorbell Blinking Red And Blue
Understanding why your doorbell blinks these colors helps you fix the issue faster. Here are the most frequent causes:
1. Wi-fi Problems
If your Wi-Fi is weak or disconnected, the doorbell struggles to connect. It blinks red and blue while searching for a signal.
2. Setup Incomplete
When you first install the doorbell, or reset it, it enters setup mode. It blinks red and blue until setup finishes.
3. Firmware Update
Blink devices update their software automatically. During updates, the doorbell blinks red and blue.
4. Low Battery Or Power Issues
If the battery is low, the red light appears. Sometimes, power problems cause both lights to blink.
5. Hardware Error
Rarely, a hardware failure causes blinking lights. This can mean the device needs repair.
6. App Sync Issues
If the Blink app loses sync with the doorbell, the lights blink to show a communication problem.

Step-by-step Troubleshooting Guide
If your Blink Doorbell is blinking red and blue, follow these steps to fix the problem. Most issues can be solved at home, without expert help.

Your device needs a strong Wi-Fi signal to work. Here’s how to check:
- Open the Blink app and see if your device is online.
- Move your router closer or remove obstacles between router and doorbell.
- Restart your router. Wait two minutes and check again.

If you are installing the doorbell for the first time, or after a reset:
- Open the Blink app.
- Follow the instructions for setup.
- Make sure the device connects to Wi-Fi and is added to your account.

During updates, the doorbell may blink for several minutes.
- Do not remove batteries or unplug the device.
- Wait up to 10 minutes.
- If the blinking does not stop, restart the device.
4. Replace Batteries
If the red light keeps blinking:
- Open the doorbell’s back panel.
- Remove the old batteries.
- Insert new, high-quality AA lithium batteries.
- Close the panel and check the lights.
5. Restart Or Reset The Device
If none of the above steps work:
- Press and hold the reset button (usually inside the battery compartment).
- Wait for the lights to blink.

How To Prevent Blink Doorbell Blinking Issues
Preventing problems is easier than fixing them. Here are practical ways to keep your doorbell working smoothly:
1. Keep Wi-fi Strong
Place your router in a central location. Avoid thick walls or metal objects between router and doorbell.
2. Update Firmware Regularly
Allow the Blink app to update devices. Do not block updates or disconnect during the process.
3. Use Quality Batteries
Choose AA lithium batteries. Cheap batteries drain fast and cause errors.
4. Check Device Monthly
Open the Blink app once a month to check device status and battery level.
5. Avoid Extreme Weather
Blink doorbells work best between -4°F and 113°F (-20°C to 45°C). Extreme cold or heat causes battery and hardware problems.
6. Keep App Updated
Install the latest Blink app version. Updates fix bugs and improve stability.
Non-obvious Insights
- Most people forget to check their Wi-Fi network name. After changing your Wi-Fi, you must reconnect the doorbell or it will blink red and blue.
- Firmware updates sometimes pause if battery is low. Replace batteries before updating to avoid interruptions.
