Why Is the Electromagnetic Lock Making a Loud Noise When Closing? Three Solutions to Try

Common Faults and Solutions for Electromagnetic Locks

1. Loud Noise When the Magnetic Lock Closes

• a. Check if rubber gaskets are installed.
• b. Inspect whether the screws on the iron plate end are too loose.
• c. Verify that the distance between the magnetic lock body and the suction plate is appropriate.

2. Iron Plate Fails to Hold Firmly

• a. Check if the power supply's output (1A/12V/24V) has decreased.
• b. Examine the surface of the magnet for foreign objects (such as dust, rust, debris, etc.).

3. Iron Plate Requires Frequent Adjustment

• a. Check if the iron plate is equipped with dowel pins.
• b. Check if a rubber pad is installed on the iron plate.
• c. It is recommended to apply thread locker to the screws.

4. Slight Vibration When the Iron Plate Is Held

• a. Ensure the main surface of the magnetic lock and the iron plate are fully engaged with no foreign objects, or try loosening the iron plate slightly.
• b. Check if the voltage and current are sufficient.

5. Delay Function Not Working

• a. The "delay adjustment" of the magnetic lock starts timing after power-on, not after closing.
• b. The magnetic lock has delay settings of 0, 3, 6, and 9 seconds. Check if the setting is mistakenly set to 9 seconds.

6. LED Light Dim and Fails to Hold After Power-On

• Check if the voltage is sufficient to meet the electromagnetic lock's requirements (should supply 1A current/12V voltage).

7. Red LED Light Stays On, but Green Light Does Not Turn On After Power-On

• The induction component of the magnetic lock may be damaged and needs to be replaced.

8. Double-Door Magnetic Lock Fails to Hold After Period of Use

• Double-door magnetic locks have higher power consumption. Check if the power supply is adequate (whether it meets the current and voltage requirements of the double-door electromagnetic lock, or if there is line loss).

9. No Action When Paired with a Controller

• Check if the "output" contacts of the controller are correctly connected.
