OVERLOAD

For technicians ordering by number, part F620058-66 corresponds to the overload. In commercial equipment, small differences in revisions can change fitment, so it’s worth verifying the exact part number and placement. As a overload protector, this part is used to restore compressor protection and thermal trip behavior. Service calls involving this part type often mention compressor trips, not cooling consistently, and overcurrent trip. Technicians often replace this component after confirming hot shutdowns, repeated trips, or restart-after-cool-down behavior. A practical diagnostic path is to confirm the symptom, then test the related circuit or assembly and inspect nearby components for secondary damage. Overload protectors are typically replaced after verifying compressor amperage and checking for conditions that cause overheating or repeated thermal trips. Once the failed part is confirmed and replaced, cycle behavior should normalize and performance should return to expected operation. Disconnect power before service, document the original layout with a photo, and reinstall so nothing pinches, rubs, or binds. After installation, run a short test cycle and check for stable operation, leaks, vibration noise, and any recurring fault symptoms. 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.
