How to Fix / Troubleshooting
Safety: Do not touch live electrical parts. Turn off power before removing covers.
Steps:
- Identify source: With the cover removed (and power restored cautiously), listen from a safe distance to locate the buzzing component (contactor, transformer, or inverter board).
- Tighten mounting: Turn power off again and tighten mounting screws on the noisy component to reduce vibration.
- Check for resonance: Ensure wiring harnesses are not touching vibrating components.
If the noise is excessive or accompanied by overheating, the Poolex inverter PCB or contactor may need replacement by a technician.
