OVERLOAD

This listing centers on part 18-8772-21, a overload used in ice machine and refrigeration maintenance. It is commonly ordered when a machine still has power available but a specific circuit, movement, or cooling function is no longer working correctly. Always verify the brand family and machine series used on the service call so the replacement matches correctly. Model verification is important because close machine variants may use different revisions of the same component category. Protects and resets the compressor circuit when overheating or overload conditions cause shutdown and restart problems. Field complaints tied to this part type often include hot shutdowns, compressor trips, and restarts after cooling. An overload protector issue may appear as shutdown after heating and restart only after the system cools down. For this overload protector 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. With overload protectors, technicians typically verify compressor condition and current draw so the new protector is not exposed to the same fault. Service buyers often keep the removed part on hand during installation to compare terminals, orientation, and mounting points. Once the failed part is confirmed, replacing it with the correct item can restore normal function and prevent ongoing intermittent complaints. 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.
