  1. Locate the bumps on the top of your refrigerator door that correspond to the switches on the cabinet.
  2. With the doors open, take two decently powerful magnets and press them against the switch locations on each side of the door.
  3. Test the door switches by sliding one magnet left and right to trigger the switch, while ensuring the other magnet is directly on the switch.
  4. If the magnets fail to trigger the door switches, there may be a loose wire or component failure in the door switch system.

Step 3: Inspect the Plastic Top of the Refrigerator

  1. Use a Phillips head screwdriver to loosen and remove the three screws located in the plastic top.
  2. Open the plastic cover on the left side to access wire harness connectors and the water connection from the door.
  3. Check for any dislodged or damaged wire harness connectors, as these are common points of failure.
  4. In some models, the reed switch controlling the magnetic door shutoff is hidden behind the wires. Look for any physical issues or use a multimeter to test for continuity.
  5. If necessary, unplug the refrigerator before replacing or repairing any components, wires, or control boards to ensure safety.

Step 4: Evaluate Cooling Functionality

  1. If the beeping persists despite the door alarm and switch checks, consider the refrigerator’s cooling performance.
  2. Ensure the refrigerator feels cool and check the temperature controls on the door.
  3. If the displayed numbers do not match the actual temperature, it may indicate faulty sensors in the refrigerator or freezer cabinets.
  4. However, if the cabinet feels warm or hot, there may be a more significant issue with the unit’s cooling system that requires professional assistance.


By following these troubleshooting steps, you can effectively address the beeping issue in your freezer, even when the door is closed. Remember to check the door alarm, test the door switches, inspect the plastic top, and evaluate the cooling functionality. In most cases, these simple DIY steps can resolve the problem. However, if the issue persists or if you encounter more complex problems, it’s advisable to seek the help of a qualified technician. Enjoy a peaceful and quiet freezer once again!
