Dryer Thermal Cut-Off / High-Limit Safety Kit

The 279973 Kit provides over-temperature protection in electric dryers by combining one or more thermal cut-off devices (fuses or thermostats) that open the heating circuit if internal air temperature exceeds safe limits. It helps prevent overheating that could lead to damage or fire.

Key Features:

• Includes a thermal fuse and high-limit thermostat (or equivalent safety devices) for redundant protection

• Non-resettable design: once open, the device must be replaced

• Low resistance in normal operation to avoid voltage drop to the heating element

• Compact mounting form compatible with factory heater housing or blower housing locations

• Replaces legacy safety parts such as 3977395, 3404151, 3404152, 8318314

• Compatible with many Whirlpool, Kenmore, Maytag, and affiliated dryer models that list 279973 (or its equivalents) as the thermal safety kit part number
