This resistive heating element cycles on during the defrost period to melt frost accumulation from the evaporator coil, maintaining proper airflow and heat-transfer efficiency across the refrigeration circuit. It is installed by commercial refrigeration technicians as part of routine defrost system maintenance or in response to defrost failure diagnostics. The heater measures 33.5 inches in length, making it a dimensional match for the evaporator assembly it serves.\u003c\/p\u003e\n\u003cp\u003eThis defrost heater is intended for use in commercial refrigeration applications consistent with MASTER-BILT equipment, specifically referenced under model designator CL-5-75. It is suited for walk-in coolers, reach-in units, or similar commercial refrigerated enclosures that use a timed or demand-initiated electric defrost system. Installation is performed during a scheduled defrost cycle service or when frost buildup, elevated case temperatures, or defrost board fault codes indicate heater failure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e550-watt output provides sufficient heat for evaporator coil defrost in commercial refrigeration applications\u003c\/li\u003e\n  \u003cli\u003e115-volt rating compatible with standard commercial single-phase power circuits\u003c\/li\u003e\n  \u003cli\u003e33.5-inch element length for dimensional fit within the evaporator coil assembly\u003c\/li\u003e\n  \u003cli\u003eOEM MASTER-BILT replacement part, sourced to match original equipment specifications\u003c\/li\u003e\n  \u003cli\u003eReferenced under model designation CL-5-75 for accurate cross-reference identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement defrost heater for MASTER-BILT commercial refrigeration equipment referenced under model designation CL-5-75.

Before servicing, disconnect all electrical power to the unit and allow the evaporator coil to fully defrost and drain. Handle the heater element carefully to avoid cracking the sheath, and confirm all terminal connections are secure and rated for the circuit before restoring power. Work should comply with applicable local electrical codes and NEC requirements for commercial refrigeration equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e: 550 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElement Length\u003c\/strong\u003e: 33.5 inches\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: MASTER-BILT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17-09230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER-BILT","offers":[{"title":"Default Title","offer_id":51199983518002,"sku":"17-09230","price":88.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307158800.jpg?v=1779687366","url":"https:\/\/voomisupply.com\/products\/master-bilt-17-09230-defrost-heater-550w-115v","provider":"Voomi Supply","version":"1.0","type":"link"}
