START CAPACITOR

The component sold under part number 18-1901-65 is the start capacitor, commonly ordered for repair jobs. Technicians often source this part after verifying the installed component is cracked, out of tolerance, heat-damaged, seized, or otherwise unreliable. Always verify the brand family and machine series used on the service call so the replacement matches correctly. If your machine has multiple production revisions, confirm the exact model and serial details before finalizing the order. Supports motor or compressor starting/running when the machine has hard starts, humming, or intermittent startup. Depending on the machine setup, failures in this part category can show up as slow starts, intermittent startup, and humming and not starting. A weak or failed capacitor can leave a motor or compressor humming, starting slowly, or failing to start under load. For this capacitor category, the typical repair goal is to restore the function that the failed component was affecting. A good service approach is to verify the exact part number and inspect the surrounding assembly before replacing the component. Capacitor diagnosis typically includes measuring capacitance, looking for bulging or leakage, and checking the connected motor/compressor current draw. Verifying the complaint under operating conditions before and after replacement is a practical way to confirm the issue is resolved. Using the exact replacement part number after diagnosis helps correct the issue at the source instead of masking the symptom temporarily. Before checkout, verify the part number on the old component and the machine identification tag. Many service calls involve symptoms like not turning on, no power, not cooling, not starting, intermittent operation, error code faults, or ice not dropping, but those complaints can come from multiple causes. Accurate diagnosis plus correct part-number matching is the best way to avoid delays and repeat service visits.
