Part 279973 Thermal Cut-Off / High-Limit Kit
Purpose
Protects dryer heater from overheating
Details
This is the genuine OEM thermal cut-off fuse and high-limit thermostat kit used in many Whirlpool-family electric dryers. When internal temperatures exceed safe limits, this kit interrupts power to prevent damage or fire. A failed kit can result in no heat, intermittent heating, or the dryer shutting off prematurely. Replacing both parts restores safe heat regulation and reliable dryer operation.
Included Items
One thermal cut-off fuse and one high-limit thermostat.
Compatible Models
This kit fits many Whirlpool, Kenmore, Maytag, and related electric dryer models. Always confirm with your dryer’s parts diagram before ordering.
