Dryer Thermistor & Dual Thermal Fuse Replacement Kit (8577274, 3392519, 3390719)
Product description
What you receive: one 8577274 dryer thermistor and two thermal fuses — one 3392519 and one 3390719 — supplied as a matched repair kit for top-load dryer applications.
Compatibility: The components are designed to fit a broad range of Whirlpool-family machines including Whirlpool, Kenmore, Maytag, Amana, KitchenAid and Inglis top dryers. Verify the replacement by checking your model’s part numbers against 8577274, 3392519 and 3390719 to confirm fit.
Construction and sizing: Parts are built from OEM-grade materials — metal contacts, high-temperature plastics and reliable sensing elements — and are produced to match original component dimensions so they mount into existing brackets and connectors without modification.
How it’s used: The thermistor monitors drum air temperature for the control board, while the two thermal fuses provide one-time overheat protection. Typical installation involves disconnecting power, removing the dryer access panel, unplugging the old parts’ connectors, and installing the new components in the same positions. If your dryer shows heating faults, replacing these items often restores correct temperature regulation.
Performance and support: The thermistor and fuses are calibrated to factory tolerances to help maintain efficient heating cycles and safe operation. A 30-day return period is provided, and customer service is available to assist with compatibility questions or basic installation guidance.

Exactly what was needed — great value
Exact components and far cheaper than local options. My husband, a retired appliance tech, confirmed the fit and we installed them on our Whirlpool. Note: replace both thermostat and thermistor together.

Worth the purchase
I picked this after checking a specialist parts site where the same kit was much more expensive. I bought it expecting a trial, but it fixed my heating problem and the dryer has been hotter than it was from day one.

Worked when my husband installed them — avoided a technician visit and the sensors did their job. Thanks!
