LG Washing Machine Thermostat

The LG Washer/Dryer Combo Heater Safety Thermostat (Part Number: 6931FR3108A) is an authentic original equipment manufacturer (OEM) replacement thermal safety limit switch designed for LG washing machines and washer-dryer combination units. Installed directly on the heating element duct or blower housing, this surface-mount bi-metal disk thermostat monitors internal operating temperatures. If temperatures spike beyond safe factory thresholds, the internal contacts trip open to cut power to the heater, preventing thermal damage, fires, or scorched clothing.

Key Features

• Bi-Metal Thermal Limit Disc: Precision-calibrated snap-action bi-metal disc trips electrical contacts open automatically upon reaching critical temperature thresholds.

• Dual Male Spade Terminals: Outfitted with standard 1/4-inch male spade connectors for secure wire harness integration.

• Flanged Surface Mount Housing: Features a round metallic sensing face and a integrated mounting flange plate for flush seating against the heater duct.

Benefits

• Solves no-heat conditions, cold wash water, incomplete drying cycles, or appliance shutting down due to thermal tripping.

• Protects internal electrical components, wash tubs, and clothing from severe overheating damage.

• Direct OEM replacement guarantees exact temperature calibration, terminal layout, and physical mounting fitment.

Applications

Designed specifically for select LG washing machine and washer-dryer combination models requiring part number 6931FR3108A.
