Look for "over temperature," "PFC thermal overload," or "fan failure" messages.
The Galaxy 5000 uses high-speed fans to pull hot air from the PCB and inverter components. If a fan bearing begins to fail, it creates a erratic, rhythmic crackling or grinding sound rather than a smooth hum.

utilizes powerful insulated-gate bipolar transistor (IGBT) components and complex busbar structures [1.19] to process up to 480V/600V of electrical current [1.20]. Over years of thermal cycling, internal copper or aluminum connections can loosen. When a loose gap forms, current can jump across it, producing an audible crackle. This creates immense localized heat and can rapidly destroy nearby printed circuit boards (PCBs). Electrostatic Discharge (ESD) and Dust Accumulation
