Key Features

  • Critical Safety Overheat Protection: Designed as a non-resettable safety device that permanently "blows" to break the electrical circuit if the dryer internal temperature exceeds a safe limit (typically 196°F).
  • High-Conductivity Terminals: Features two 1/4-inch male spade terminals for a secure, low-resistance connection to the dryer's wiring harness, ensuring consistent power delivery.
  • Durable Heat-Resistant Housing: The fuse body is constructed from high-grade, flame-retardant plastic designed to withstand the high-vibration environment of the blower housing.
  • Quick Restoration: Provides an affordable and straightforward solution to restore dryer functionality without the need for expensive professional repairs.

Compatibility & Fitment

This thermal fuse is one of the most widely used safety components in the appliance industry. It is compatible with most 29-inch wide dryers built by Whirlpool Corporation, including:

  • Whirlpool & Kenmore: Fits a vast majority of 70, 80, 90, and 110-series residential dryers.
  • Maytag: Compatible with Centennial and Bravos models produced after 2006.
  • Additional Brands: Fits KitchenAid, Estate, Roper, Inglis, Crosley, Admiral, and Amana dryers.
  • Note: This fuse is typically located on the blower wheel housing. If your dryer has two fuses on the heater box, this may be the one paired with the high-limit thermostat.

When to Replace

  • Dryer Won't Start: On most electric dryers, a blown thermal fuse will prevent the motor from turning over entirely to prevent fire hazards.
  • No Heat: On some gas dryers, the drum may still spin, but the igniter will not glow or release gas if the thermal fuse has failed.
  • Testing for Failure: Use a multimeter to test for "continuity." If the meter does not beep or shows "OL" (Open Line) when touching both terminals, the fuse is blown and must be replaced.

Installation Tips

  • Safety First (CRITICAL): Unplug the dryer from the wall outlet or turn off the circuit breaker before removing the back panel.
  • Identify the Cause (PRO TIP): Thermal fuses rarely blow without a reason. Before installing the new fuse, check your dryer vent hose for clogs. A blocked vent is the #1 cause of overheating and blown fuses.
  • Check the High-Limit Thermostat: Often, the high-limit thermostat (located near the fuse) fails at the same time. It is highly recommended to inspect or replace both as a pair to ensure a permanent repair.
  • Vacuum the Blower: While the back panel is off, take a moment to vacuum out the lint buildup around the blower wheel and motor area to improve airflow and prevent the new fuse from blowing.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
