Safety: Repeated tripping indicates a serious electrical fault. Do not keep resetting the breaker.

1. Visual inspection: With power off, remove the cover and look for signs of water leaks onto the PCB, fan, or wiring.
2. Dry and fix leaks: If moisture is present, identify and repair the leak source before drying components.
