How to Repair Noisy, Squeaking & Humming Ceiling Fan | Replace Capacitor & Bearing | KDK KY14ES

Today, I want to show you how to troubleshoot and repair a noisy ceiling fan, KDK KY14ES. In addition, I will service and deep clean this fan. When you hear humming or squeaking from your ceiling fan, it's usually because some of its components are faulty.

Step 1: Removal
  1. Open the fan rod cover and remove the wiring supply from the terminal block. Please make sure the power supply is OFF and isolate it.
  2. Remove safety wire, cotter pin, nut, and bolt from the fan rod, then remove the fan.

  3. Remove another cotter pin, nut, and bolt, then remove the fan rod.
  4. Remove decoration cap and 4 fan blades (2 screws on each blade).

  5. Remove the top cover (3 screws).
  6. Remove PCB cover, base, safety wire, and secondary terminal block wiring.
  7. Remove PCB wiring using soldering iron.
  8. Unscrew 3 screws at the secondary top cover and remove the secondary decoration cover.



  9. Remove the IR cover (1 screw behind the main rod fan).
  10. Insert the wiring into the main fan rod, then remove the secondary top cover (3 screws). Wiggle a little bit to loosen it, and then you can easily remove the inner top cover.
  11. Remove bearing accessories.


  12. Pry the plastic bottom cover to remove it.


  13. Remove the IR PCB cover (3 screws), then remove IR PCB (2 screws).



  14. Remove earthing wire from the fan rod.


  15. Remove top bearing using 2 jaws puller.



  16. Remove the metal inner bottom cover using 3 jaws puller, then remove a bearing.



Step 2: Installation
  1. Replace or lubricate both bearings if your fan has a squeaking noise problem. Recommend replacing the bearing for good practice. Install new bearing 6203ZZ type as a replacement for both sides.




  2. Install the fan parts and components in reverse order of removal.

  3. Remove the 3 brown capacitors and one safety capacitor. A defective capacitor or improperly installing the rod cover can cause a humming noise.



  4. Check the capacitance for these 4 capacitors using a multimeter or ESR meter. Make sure the capacitance is within the range.

    Within the limit range of capacitance value

    Within the limit range of capacitance value

    Within the limit range of capacitance value

    Within the limit range of capacitance value

    I need to replace 0.1 uF because the tolerance capacitance value is out of range

Step 3: Test
  1. Switch on the fan. No more noise coming from a fan.
