Run Capacitor

If you’re sourcing the correct replacement, match part F620167-16 to the run capacitor. If the machine has multiple production revisions, confirm the unit tag and the original part markings before purchase. As a capacitor, this part is used to restore starting and running performance for motors/compressors. Common complaints tied to this category include startup trip, weak startup, and intermittent start. Technicians often replace this component after confirming humming and not starting, weak startups, or intermittent starts. Before replacement, technicians typically verify inputs/outputs (or fitment/movement for mechanical parts) so the root cause is confirmed. Capacitor service often includes checking capacitance value, inspecting terminals for heat damage, and confirming the connected motor/compressor is not locked. Replacing the correct component helps restore predictable operation and reduces repeat service calls when the diagnosis is accurate. If the part is in a water path, do a leak check during the first run and again after the unit has operated for a short period. Recheck fasteners and connectors after the first cycle to confirm everything remains tight under vibration and normal operation. 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. If multiple symptoms overlap, complete the diagnosis before ordering so the replacement targets the true root cause.
