The Intel AS‑3345 is a CPU control board used in all‑electric injection molding machines (e.g., Sumitomo models). Common failures on this class of boards include burnt or cracked power‑management ICs, degraded MOSFET gate drivers, and capacitor leakage that cause intermittent shutdowns or loss of servo drive signals. Begin troubleshooting by verifying the 24 V/48 V supply rails to the board, inspecting for visible burn marks or swollen electrolytics, and checking the status LEDs or diagnostic outputs on the machine’s HMI for error codes related to power‑management or motor control.[oss-gpt-20b] |
