CAPACITOR

The capacitor identified as part 18-8741-29 is a replacement component used during equipment repairs. A replacement like this is typically used when the installed component shows age, damage, or performance drift that affects normal operation. Brand compatibility should be matched to the exact machine nameplate and part number before ordering. 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. When this component fails, technicians may see issues such as intermittent startup, slow starts, 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. During diagnosis, the part number should be matched first, then the circuit or assembly should be tested to confirm the failure path. For capacitor-related repairs, technicians commonly test capacitance value, inspect terminals for heat discoloration, and check for swelling or leakage. After installation, technicians typically monitor startup or cycle operation to confirm the machine returns to normal behavior. 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.
