Westinghouse 626548R Inducer Limit Switch 145F Upflow Furnace

Product Description

The WESTINGHOUSE 626548R is an inducer limit switch rated at 145 degrees F, designed to protect the heat exchanger and venting system in gas furnaces. This limit switch monitors exhaust gas temperatures at the inducer assembly and opens the control circuit when temperatures exceed the rated set point, shutting down the burner to prevent overheating. It is a 1/2D form-factor device, a standard configuration for residential inducer-side limit applications. Licensed HVAC technicians install and replace this component as part of routine furnace diagnostics and safety-device servicing.

This inducer limit switch is specified for use on L1RC/G6TC-B Upflow/Horizontal furnace configurations. It is suited to residential gas furnace installations where inducer draft monitoring and high-temperature cutout protection are required. The 1/2D disc size corresponds to the mounting footprint used on the inducer housing in these upflow and horizontal furnace orientations.

Key Features

• 145 degrees F set-point temperature rating for inducer-side overheat protection
• 1/2D disc form factor for direct OEM-style fitment on compatible furnace inducer housings
• Opens control circuit on temperature exceedance to shut down burner operation
• Designed for upflow and horizontal furnace orientations
• Serves as a safety-critical limit device in the furnace control sequence

Compatibility

Specified for use on L1RC/G6TC-B Upflow/Horizontal Furnace models.

Installation Notes

Installation and replacement of inducer limit switches should be performed by a licensed HVAC technician. Shut off power to the furnace at the disconnect and allow the heat exchanger and inducer assembly to cool completely before servicing. Verify the replacement part matches the original set-point temperature and disc diameter before installation. Refer to the furnace manufacturer service manual and applicable local mechanical codes for proper limit switch location and wiring procedures.
