The sensor monitors outdoor coil temperature and signals the control board to initiate or terminate defrost cycles, preventing ice buildup that reduces system efficiency. At 34 inches in length, it reaches the coil mounting positions found in standard split system configurations. Licensed HVAC technicians install this sensor as a direct replacement during defrost system troubleshooting or scheduled maintenance on heat pump equipment.\u003c\/p\u003e\n\u003cp\u003eThe 626491R is specified for use on the T5BX split system heat pump. It is suited to residential split system heat pump applications where a failed or degraded defrost sensor is causing improper defrost cycle operation, such as short cycling, failure to defrost, or continuous defrost lockout. Technicians typically identify the need for this sensor during off-season startup checks or in response to ice accumulation on the outdoor coil during heating operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e34-inch lead length provides reach to coil mounting locations in split system outdoor units\u003c\/li\u003e\n  \u003cli\u003eDesigned to monitor outdoor coil temperature for accurate defrost cycle initiation and termination\u003c\/li\u003e\n  \u003cli\u003eOEM-specified replacement for T5BX split system heat pump applications\u003c\/li\u003e\n  \u003cli\u003eDirect replacement fit reduces diagnostic and installation time in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use on the WESTINGHOUSE T5BX split system heat pump.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDefrost sensor replacement is performed by a licensed HVAC technician. Disconnect and lock out power to the outdoor unit at the disconnect box before beginning any service work. Secure the sensor to the coil per the original mounting method and route the lead wire away from sharp edges or moving components. Verify defrost cycle operation after installation by confirming the system enters and exits defrost mode within normal parameters for the equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Defrost Sensor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Length\u003c\/strong\u003e: 34 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Split System Heat Pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Model\u003c\/strong\u003e: T5BX\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTINGHOUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 626491R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284071645490,"sku":"626491R","price":27.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277917.jpg?v=1781067809","url":"https:\/\/voomisupply.com\/products\/westinghouse-626491r-defrost-sensor-34-inches-heat-pump","provider":"Voomi Supply","version":"1.0","type":"link"}
