It is a \u003cstrong\u003ebrass-cased thermistor probe\u003c\/strong\u003e on a \u003cstrong\u003etwo-conductor black lead\u003c\/strong\u003e ending in a \u003cstrong\u003ewhite two-position plug-in connector\u003c\/strong\u003e, so it connects to the compressor's electronic \u003cstrong\u003econtrol module\u003c\/strong\u003e or system controller without splicing. Discharge-line temperature climbs fast when a compressor is in trouble, so this sensor gives the control an \u003cstrong\u003eearly warning of overheating\u003c\/strong\u003e and lets it alert or shut the compressor down before the oil breaks down and valves, scrolls or bearings are damaged. Copeland's \u003cstrong\u003eCoreSense Diagnostics\u003c\/strong\u003e literature describes discharge line temperature probes plugging into the module's \u003cstrong\u003ethermistor input\u003c\/strong\u003e to protect against \u003cstrong\u003ehigh discharge temperature\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eA thermistor is a temperature-sensitive resistor; most discharge-line types are \u003cstrong\u003enegative temperature coefficient (NTC)\u003c\/strong\u003e, meaning resistance drops as the line gets hotter. The control reads that resistance and converts it to a temperature. A \u003cstrong\u003efailed, open, shorted or poorly mounted sensor\u003c\/strong\u003e shows up as \u003cstrong\u003enuisance high-discharge-temperature lockouts\u003c\/strong\u003e, \u003cstrong\u003eerratic temperature readings\u003c\/strong\u003e, a \u003cstrong\u003esensor fault or open-circuit code\u003c\/strong\u003e, or no protection at all. When you install the replacement, mount it on the \u003cstrong\u003edischarge line\u003c\/strong\u003e close to the compressor outlet just as the original was, with firm contact against clean tubing, and \u003cstrong\u003einsulate\u003c\/strong\u003e it the way the original was so ambient air does not skew the reading. Match the \u003cstrong\u003eplug-in connector\u003c\/strong\u003e to your control before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEarly Overheat Warning:\u003c\/strong\u003e Reads \u003cstrong\u003edischarge line temperature\u003c\/strong\u003e continuously so the control can react before \u003cstrong\u003ecompressor damage\u003c\/strong\u003e occurs.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOEM Copeland Sensor:\u003c\/strong\u003e Specified by Copeland for use with its compressor controls, so the \u003cstrong\u003eresistance curve\u003c\/strong\u003e matches what the control expects.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePlug-In Connector:\u003c\/strong\u003e The \u003cstrong\u003ewhite two-position connector\u003c\/strong\u003e plugs straight into the control; no splicing or crimping.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQuick Diagnostic Fix:\u003c\/strong\u003e Eliminates \u003cstrong\u003efalse high-discharge trips\u003c\/strong\u003e and \u003cstrong\u003esensor fault codes\u003c\/strong\u003e caused by an aged or damaged probe.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHow do I test the thermistor?\u003c\/strong\u003e Unplug it and measure resistance across the two conductors, then compare that reading at the line temperature to the sensor chart for your control.
