It steps down line voltage to the low-voltage control circuit that powers the thermostat, control board, and gas valve in a forced-air gas furnace. Rated at 40 VA, it provides adequate capacity for standard residential control circuit loads. Licensed HVAC technicians install this part during routine maintenance or when diagnosing control circuit failures such as blown fuses, failed heating sequences, or a thermostat that fails to trigger the burner.\u003c\/p\u003e\n\u003cp\u003eThe 622341R is specified for use in WESTINGHOUSE G7SA-1, G7SC-1, and G7SD-1 upflow and horizontal configuration gas furnaces. These are residential forced-air furnace platforms where the transformer is mounted inside the furnace cabinet and wired into the primary electrical supply and the 24-volt secondary control circuit. The dual primary wiring accommodates both 120-volt and 240-volt supply configurations, making the part suitable across different electrical service arrangements without requiring a different transformer for each voltage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40 VA rating supports standard residential furnace control circuit loads\u003c\/li\u003e\n  \u003cli\u003eDual primary voltage input: 120 volts AC or 240 volts AC at 60 Hz\u003c\/li\u003e\n  \u003cli\u003eDesigned for upflow and horizontal furnace cabinet orientations\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part for specified WESTINGHOUSE furnace models\u003c\/li\u003e\n  \u003cli\u003eSteps line voltage down to low-voltage control circuit level for thermostat and gas valve operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use with WESTINGHOUSE G7SA-1, G7SC-1, and G7SD-1 upflow and horizontal gas furnaces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the furnace manufacturer service documentation. Disconnect and lock out all electrical power to the furnace before removing the existing transformer or handling any wiring. Verify the primary voltage tap matches the supply voltage before energizing the unit. Confirm the secondary output voltage with a multimeter after installation to ensure the control circuit is receiving the correct voltage before restoring thermostat operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Transformer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Voltage\u003c\/strong\u003e: 120\/240 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVA Rating\u003c\/strong\u003e: 40 VA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Upflow and Horizontal Gas Furnace\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: 622341R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284029014322,"sku":"622341R","price":34.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277869.png?v=1781066557","url":"https:\/\/voomisupply.com\/products\/westinghouse-622341r-furnace-transformer-40-va-120-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
