Why Your Maglock Is Failing: 9 Issues and Practical Fixes

Electromagnetic locks (maglocks) operate based on the principle of electromagnetism. When powered, even a small electrical current can generate a strong magnetic force. Once the access control system verifies an authorized user, the maglock loses its magnetic force, allowing the door to open.

After extended use, electromagnetic locks may experience various issues. Here are some common problems and their recommended solutions:

1. Loud Noise When Door Closes

• a. Check if rubber pads are installed.

• b. Inspect whether the screws on the armature plate are too loose.

• c. Ensure the distance between the lock body and the armature plate is appropriate.

2. Armature Plate Not Holding Firmly

• a. Verify if the power supply is providing sufficient power (1A at 12V/24V).

• b. Check for foreign objects (dust, rust, debris, etc.) on the magnet surface.

3. Armature Plate Frequently Needs Adjustment

• a. Ensure that the armature plate is equipped with a fixing pin.

• b. Confirm if rubber pads are installed.

• c. It’s recommended to apply threadlocker to the screws.

4. Slight Vibration After Locking

• a. Check if the lock body and the armature plate are fully aligned and free of debris. Try loosening and readjusting the plate.

• b. Ensure that the voltage and current are sufficient.

5. Delay Function Not Working

• a. The delay timer starts once the lock is powered, not after the door is closed.

• b. Check if the delay time is set properly (options usually include 0, 3, 6, or 9 seconds).

6. Weak LED Light and Lock Not Holding After Power-On

• Confirm if the power supply is adequate to meet the electromagnetic lock’s requirement (should be at least 1A/12V).

7. Red LED Stays On After Power-On, But Green LED Does Not Light Up

• This may indicate a damaged sensing component in the lock. Replacement is likely needed.

8. Double-Door Maglock Fails to Hold After a While

• Double-door maglocks consume more power. Check if the power supply can handle the required current and voltage, and inspect for any wiring loss.

9. No Response When Used with Controller

• Check if the controller’s output connections are correct.

These are the nine most common issues and corresponding solutions for electromagnetic locks used in access control systems. In real-world applications, specific problems should be analyzed on a case-by-case basis.
