It converts 115-volt primary power to a 24-volt secondary output at 20 volt-amperes (VA), providing the low-voltage power required to operate thermostats, control boards, and other 24-volt components in a forced-air heating system. This transformer is a direct OEM-style replacement part intended for installation by licensed HVAC technicians servicing Nordyne and Intertherm brand furnace equipment. The 20 VA capacity is sized to handle standard residential low-voltage control loads without overheating under normal operating conditions.\u003c\/p\u003e\n\u003cp\u003eThis transformer is suited for residential forced-air gas furnace applications where a reliable 24-volt control circuit is required. It is a replacement for legacy part number 104379000 as noted in supplier sourcing data. Installation is typical in the control section of the furnace cabinet, where low-voltage wiring connects the transformer secondary to the thermostat circuit and control board. Current replacement cross-reference 620825R supersedes this part number.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e115-volt primary to 24-volt secondary step-down design for standard residential furnace control circuits\u003c\/li\u003e\n  \u003cli\u003e20 VA output capacity handles typical low-voltage thermostat and control board loads\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part — supersedes legacy part number 104379000\u003c\/li\u003e\n  \u003cli\u003eMatched to Nordyne and Intertherm furnace platform specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eIdentified as a replacement for legacy Nordyne part number 104379000.

Disconnect and lock out all power to the furnace at the disconnect switch or breaker before removing or installing any transformer. Verify primary voltage at the furnace matches the transformer rating before energizing. Low-voltage wiring connections should comply with NEC Class 2 circuit requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Voltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Capacity\u003c\/strong\u003e: 20 VA\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: NORDYNE INTERTHERM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 620825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Nordyne Intertherm","offers":[{"title":"Default Title","offer_id":51138557968690,"sku":"620825","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531287.jpg?v=1778259118","url":"https:\/\/voomisupply.com\/products\/nordyne-intertherm-620825-furnace-transformer-20va-115v-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
