My VDB770 doorbell has a solid yellow light and is warm.
This indicates the VDB770 is in Cool Down Mode This means the components are getting too warm.
- The ADC-VDB770 is designed to channel heat away from key components to the backplate. As a result, the backplate may reach higher temperatures than other exterior surfaces.
- The ADC-VDB770 is rated to operate in temperatures between -22°F (-30°C) and 104°F (40°C). In regions where temperatures are expected be near or above 104°F, avoid installing in direct sunlight.
If the device has entered a high temperature cool-down state (indicated by solid yellow LED), the device will only be able to enter button modes either via USB in a lower ambient temperature environment or by disconnecting power to the doorbell, allowing the device to cool, and moving it to a cooler for 30 minutes or so location before restoring power.
Be sure to let the device cool and take precaution as the device may be hot to the touch.
How long will it take to cool down?
There is no specific amount of time. This may be dependent on ambient temperature or if the doorbell is installed in direct sunlight.
Why is the chime not working for me?
If the device is above the maximum rated ambient temperature (104°F), the internal component temperatures may rise to a level where video doorbell functionality is no longer able to operate. The Chime may not work in this state. You will want to resolve the heating issue first before moving to the chime.
You will also want to check wiring to ensure the device is wired correctly and using the correct transformer.
