7. Safety Features
Your MASTERFUN Automatic Chicken Coop Door is equipped with advanced safety features to protect your flock.
7.1 Anti-Pinch Protection
If the door detects an obstruction (e.g., a chicken) during closing, it will automatically rebound and wait 10 seconds before attempting to close again. This process repeats up to 4 times. If the obstruction remains, a loud alarm will sound on both the door and the remote control, and the obstacle status icon will be displayed.

The anti-pinch feature ensures the safety of your chickens by reversing if an obstruction is detected.
7.2 Predator Alert System
A built-in 120° motion sensor detects approaching predators. Upon detection, the door triggers a deterrent alarm at the coop. Simultaneously, your indoor remote controller will sound an alert, providing instant notification of potential threats.

The motion sensor detects predators and activates an alarm, alerting both the coop and the remote control.

The door is built to endure various weather conditions, ensuring durability and reliability.
9. Maintenance
To ensure optimal performance and longevity of your automatic chicken coop door, regular maintenance is recommended:
- Cleaning: Periodically clean the door tracks and sensor areas to prevent debris buildup that could obstruct movement or sensor function. Use a soft, damp cloth.
- Battery Check: Monitor the battery levels on your remote display. Recharge the door unit and remote as needed, especially during prolonged cloudy periods if relying on solar power.
- Screw Tightness: Occasionally check the mounting screws to ensure they remain secure, but avoid overtightening.
10. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Solution |
|---|---|
| The remote control and timer do not work. | Ensure the remote control is properly connected to the door. The blue light on the door should be off, and the signal icon should be visible on the remote screen. |
| The door is stuck and cannot open or close properly. | Check if the screws were tightened too much during installation. Over-tightening can affect the rolling movement. Slightly loosen the screws and test the door again. |
| The door does not open or close at the scheduled time. | Verify that the real-time clock on the remote control matches your local time. Also, check if the alarm icon on the screen is flashing, which usually indicates a low battery interruption. |
| The remote beeps for about 20 seconds at night. | Check the remote screen. If the obstacle status or alarm icon is active, it means a predator or another object may have triggered the sensors. |
