WPW10316428 Whirlpool Refrigerator Defrost Heater – Fix Frost Buildup, No-Cool Failures, and a Freezer That Won’t Defrost

When your Whirlpool, Maytag, or Amana refrigerator stops cooling, develops heavy frost on the evaporator coils, or runs constantly without reaching temperature, the defrost heater assembly WPW10316428 is the most common cause. This heater melts frost off the evaporator coils during each defrost cycle — when it fails, ice builds up and blocks airflow entirely. Replaces W10316428. OEM and used options available.

Is This the Part You Need?

This heater is located behind the freezer back panel, wrapped around or mounted near the evaporator coil. If your fridge is warm but the freezer has a solid block of ice on the back wall, this is the part to check first. Confirm your model number on the label inside the fridge door or on the side wall before ordering.

Symptoms of a Failed Defrost Heater

  • Refrigerator not cooling — freezer may still be cold
  • Heavy frost or ice buildup on the back wall of the freezer
  • Fridge runs constantly but never reaches set temperature
  • Food spoiling faster than normal
  • Loud fan noise caused by ice blocking the evaporator fan
  • Freezer fan running but no cold air reaching the fridge section
  • Defrost cycle not completing — ice never melts
  • Visible burn marks or broken element on existing heater

Part Details

  • OEM Part Number: WPW10316428
  • Replaces: W10316428
  • Item #: In diagram (confirm position on your model’s parts diagram)
  • Compatible Brands: Whirlpool, Maytag, Amana, KitchenAid, Kenmore (verify by model)
  • Options: New OEM or Used (tested, functional)
  • Barcode: 883049241443

Installation Notes

Skill level: Intermediate (2/5). Disconnect power and empty the freezer before beginning. Remove the freezer back panel to access the evaporator coil and heater assembly. Allow any existing ice to thaw fully before removing the old heater — forcing it risks damaging the coil fins. Estimated time: 30–45 min. Reconnect all wire harness terminals securely before reassembly.

Compatible Models

Fits a wide range of Whirlpool, Maytag, Amana, and KitchenAid refrigerator models. Not sure if this fits your unit? Contact us with your model number before ordering.

💡 Pro Tip — Test the Defrost Thermostat and Timer at the Same Time:
The defrost heater rarely fails in isolation. If the defrost thermostat or defrost timer is also faulty, a new heater will burn out again quickly. While you have the freezer panel off, test both components with a multimeter before reassembly — it saves a second service call and protects your new part.
