Possible Causes
Vibrating transformer or inductor on PCB, Loose mounting of line filter, Resonance in metal housing, Failing relay coil
How to Fix / Troubleshooting
Safety first: Unplug before opening the housing.
- Identify source: With the cover removed (and using extreme caution if testing live, only if qualified), localize the buzzing to a specific component such as the line filter or transformer.
- Tighten mounts: Ensure the noisy component is firmly screwed to the chassis. Add insulating washers if necessary to reduce vibration.
- Component replacement: If the noise comes from a failing relay or transformer on the main control board, replace the board.
- Housing damping: Check that metal panels are not loose and resonating; tighten screws.
