Automatic Trash Can Keeps Opening and Closing - What to Do

Automatic Trash Can Keeps Opening and Closing - What to Do

Automatic trash cans are a modern convenience designed to make waste disposal more hygienic and hands-free.

There’s a range in the market and amongst these, you would want one that is reliable like this Hygio Smart Bin.

Using motion sensors, these bins detect when someone is nearby and open automatically. However, when an automatic trash can begins to open and close repeatedly without prompt, it can be frustrating and puzzling. Let’s explore why this might be happening and how to fix it.


Common Causes of Malfunction

Sensor Obstruction or Malfunction
The most common reason for an automatic trash can to repeatedly open and close is a problem with the infrared motion sensor. This could be caused by:

Dirt, dust, or fingerprints on the sensor window

Strong light sources interfering with the sensor

Pets or moving objects triggering the motion detection

Solution: Clean the sensor with a soft cloth and make sure nothing is in the sensor’s line of sight. Avoid placing the can near reflective surfaces or strong sunlight. 

Low or Dying Batteries
A weak power supply can cause the lid motor to behave erratically. If the batteries are low, the lid may not open or close properly, or may continuously cycle.

Solution: Replace the batteries with a fresh set and make sure they’re inserted correctly. Rechargeable batteries may not always provide consistent voltage, so consider using standard alkaline batteries if possible. 

Internal Circuitry Issues
If the sensor or the internal control board is damaged, it can send false signals to the motor.

Solution: This issue often requires professional repair or replacement of the unit. Check your product warranty or contact the manufacturer’s customer service for support.

Moisture or Water Damage
Exposure to moisture (such as from cleaning or humidity in kitchens and bathrooms) can damage electronic components, leading to sensor misfires.

Solution: Ensure the unit is dry and located in a moisture-free area. If it’s already been exposed to water, you may need to dry it out thoroughly or replace it. 

Software Glitch (for Smart Models)
Some higher-end automatic trash cans include microprocessors or even app connectivity. A software error can cause them to behave unpredictably.

Solution: Reset the unit by turning it off and removing the batteries for a few minutes. Then, restart the trash can and observe its behavior.


Preventative Tips

Regularly clean the lid and sensor with a dry cloth.

Avoid direct sunlight or reflections near the sensor.

Keep the trash can away from high-traffic areas where motion might frequently trigger the sensor.

Change batteries proactively, before they run low.


When to Replace It

If the problem persists despite troubleshooting, and the can is out of warranty, it might be more cost-effective to replace it. Modern automatic trash cans are increasingly affordable and come with improved sensor technology.

Final Thoughts

An automatic trash can that constantly opens and closes can be annoying, but in most cases, it’s a fixable problem. Regular maintenance and a clean environment can extend the life of your device and ensure it functions as intended. If you’ve tried everything and it still won’t behave, it may be time to consider an upgrade or a manual alternative.
