How to Repair an Automatic Door That Won't Open

Automatic doors are convenient and provide ease of access to buildings and facilities. However, if the automatic door won't open, it can be a frustrating and even dangerous situation. In this article, we will provide step-by-step instructions on how to troubleshoot and repair an automatic door that won't open.

Step 1: Check the Power Source

The first thing to check when an automatic door won't open is the power source. Make sure the door is properly plugged in or that the circuit breaker hasn't tripped. If the power source is working properly, move on to the next step.

Step 2: Check the Door's Safety Features

Automatic doors are designed with safety features that prevent them from opening. For sliding doors, if a door panel is broken out (swung out) even in the slightest, a safety switch or sensor will prevent the automatic door from running. The door would act as if it were in the off position. On swinging doors, a similar breakout switch prevents the automatic door from running if the door is pushed in the incorrect direction. Likewise, swing side sensors are mounted overhead to prevent the door from swinging open if somebody is on the other side of the door. Check the door's safety features and make sure they are functioning properly. Remove any obstructions from the doorway and clear the sensors of any debris.

Step 3: Check the Door's Sensors

If the door's safety features are functioning properly, the issue may be with the door's sensors. Check the sensors and make sure they are properly aligned and functioning. If the sensors are misaligned or not functioning properly, the door may not open.

Step 4: Check the Door's Control Panel

The control panel is the brain of the automatic door system. It controls the sensors, motor, and other components of the door. If there is an issue with the control panel, it can prevent the door from opening. Inspect the control panel for any signs of damage or malfunction. Make sure all sensors are properly wired to the control board. If not properly wire the sensors will not be able to communicate with the door controller.

Step 5: Check the Door's Motor

If the power source, safety features, sensors, and control panel are all functioning properly, the issue may be with the door's motor. Check the motor and make sure it is properly connected and functioning. If the motor is not functioning properly, it may need to be replaced.

Step 6: Call a Professional

If you have gone through all of the troubleshooting steps and the door still won't open, it's time to call a professional. A qualified technician can diagnose the problem and recommend the best course of action to repair the automatic door.

Conclusion

An automatic door that won't open can be a frustrating and even dangerous situation. However, by following these step-by-step instructions, you can troubleshoot and repair the issue. Start by checking the power source and the door's safety features, sensors, control panel, and motor. If you are unable to diagnose and fix the issue on your own, it's best to call a professional to ensure that the door is repaired properly and safely.
