The Bosch 8733953172 Compressor Discharge Temperature Sensor monitors refrigerant temperature at the compressor discharge line in split-system heat pump outdoor condensing units, sending that reading to the control board so the unit can manage superheat, regulate compressor and defrost operation, and shut down before discharge temperatures rise high enough to break down oil or damage internal components. Its sensing element sits inside a solid copper probe tip sealed with heat shrink at the cable entry, matching the thermal behavior of the copper tubing it mounts against and picking up temperature changes quickly and accurately on the hot gas line where response speed matters most. A high temperature braided sleeve protects the lead along its full length, and the twin wire lead ends in a keyed green two pin connector that plugs directly into the factory harness, allowing a direct replacement without splicing or rewiring.
