Westinghouse 622341R Furnace Transformer 40 Va 120/240V

Product Description

The WESTINGHOUSE 622341R is a furnace control transformer rated at 40 VA with dual primary voltage capability of 120/240 volts AC at 60 Hz. 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.

The 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.

Key Features

• 40 VA rating supports standard residential furnace control circuit loads
• Dual primary voltage input: 120 volts AC or 240 volts AC at 60 Hz
• Designed for upflow and horizontal furnace cabinet orientations
• OEM replacement part for specified WESTINGHOUSE furnace models
• Steps line voltage down to low-voltage control circuit level for thermostat and gas valve operation

Compatibility

Specified for use with WESTINGHOUSE G7SA-1, G7SC-1, and G7SD-1 upflow and horizontal gas furnaces.

Installation Notes

Installation 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.
