  • Kit includes (1) 3977393 cut-off thermal fuse replacement and (1) 'old-style' 3977767 hi-limit thermostat replacement.
  • Thermal fuse is rated at 309 degrees F. Hi-limit thermostat is rated at 250 degrees F.
  • The 'old-style' 3977767 replacement thermostat, slides onto the heating element terminal. This not only connects it to the heating element, but also secures it to heater assembly without any additional hardware, such as screws. (Check out the additional product photos for a visual of how it attaches.).
  • For the 'new-style' 3390291 thermostat and 3977393 fuse replacement kit, (without the press-on attachment), order APN279816.

    This kit was an easy 5 - 10 minute install, and my dryer works like new again. Fair price and fast shipping.
