Frigidaire Refrigerator PHS67EHSB7 Freezer not defrosting

Freezer icing up or fridge not cooling? This defrost thermostat kit fixes refrigerators that won't defrost properly. 10-minute DIY repair with video.

The Defrost Heater is an OEM part for Frigidaire refrigerators. It plays a crucial role in the refrigerator's defrost cycle, melting away any frost that accumulates on the evaporator coils.

Causes of a bad Defrost Heater can include a burnt-out heating element, electrical issues such as faulty wiring, or a malfunctioning thermostat that fails to activate the heater when needed.

Symptoms of a failing Defrost Heater include:

• Buildup of frost or ice on the evaporator coils despite regular defrost cycles
• Increasingly warmer temperatures in the refrigerator or freezer compartments
• The refrigerator cycling on and off more frequently than usual
• Unusual noises from ice buildup that affects the fan

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.
