The GEC Industrial Controls S.33.15.001.B is a PCB board used in the Gemdrive Axis MK 2S servo drive controller, typically mounted on 110‑V industrial motor control panels. Common failures on this model include burnt‐out MOSFETs or IGBT modules from overcurrent spikes, capacitor degradation in the power supply section, and solder joint fatigue at high‑temperature points; similar drives also suffer from overheating of the heat sink fan or failure of the main transformer windings. First‑check diagnostics should verify that the 110 V input is stable and within spec, inspect the board for burn marks, cracked capacitors, or loose connections, and confirm that the drive’s status LEDs/diagnostic outputs are reporting normal operation before proceeding to component testing or replacement.[oss-gpt-20b]
