Start Capacitor

If you’re sourcing the correct replacement, match part F620167-41 to the start capacitor. A correct part-number match matters because similar-looking parts can have different connectors, ratings, or mounting details. As a capacitor, this part is used to restore starting and running performance for motors/compressors. Failures in this area often show up as weak startup, intermittent start, and startup trip. In repairs, replacement is considered when inspection and testing confirm the fault is tied to this component. Disconnect power before service, document the original layout with a photo, and reinstall so nothing pinches, rubs, or binds. Disconnect power before service, document the original layout with a photo, and reinstall so nothing pinches, rubs, or binds. Once the failed part is confirmed and replaced, cycle behavior should normalize and performance should return to expected operation. If the issue is intermittent, look for heat marks, vibration wear, loose connections, or binding movement that changes under load. Capacitor service often includes checking capacitance value, inspecting terminals for heat damage, and confirming the connected motor/compressor is not locked. Once the failed part is confirmed and replaced, cycle behavior should normalize and performance should return to expected operation. If multiple symptoms overlap, complete the diagnosis before ordering so the replacement targets the true root cause. Inspect surrounding wiring, tubing, and mounting points so the new part is not exposed to the same stress that damaged the old one. After a successful repair, technicians often note the symptom and test result to make future troubleshooting easier. Cleaning the area around the repair helps improve fitment and makes leak or vibration checks more reliable.
