The complete fix for an Electrolux refrigerator with defrost problems, ice buildup on evaporator coils, or a freezer that won't maintain proper temperature.
The defrost heater is a critical component that melts frost and ice buildup on the evaporator coils during the automatic defrost cycle. When this heater fails, ice accumulates on the coils, blocking airflow and preventing proper cooling. This leads to frozen food in the fresh food section, temperature fluctuations, and excessive frost in the freezer compartment.
The defrost heater fails from repeated thermal cycling over years of use. Each defrost cycle heats the element to melt ice, then cools down when the cycle ends. Eventually, the heating element burns out, develops breaks in the wire, or loses electrical continuity. When it fails, the automatic defrost system can't melt ice from the evaporator coils, causing progressive ice buildup that blocks airflow and prevents proper cooling.
Difficulty: Moderate | Time: 1-2 hours | Tools: Screwdriver, nut driver, multimeter
Steps:
Safety Note: Always unplug refrigerator before working on electrical components. Test new heater with multimeter before installation to verify continuity. Allow evaporator coils to fully defrost before reassembly.

Verify your model number and compare with your existing part to ensure proper fit.
Q: How do I know if my defrost heater is bad?
A: Test it with a multimeter. With the refrigerator unplugged, disconnect the heater and test for continuity. A working heater should show continuity (typically 10-50 ohms resistance). If it shows no continuity or infinite resistance, the heater is burned out and needs replacement.
Q: Will replacing the defrost heater fix my ice buildup problem?
A: Yes, if the heater is the failed component. A bad defrost heater is the most common cause of ice buildup on evaporator coils. However, also check the defrost timer, defrost thermostat, and defrost control board to ensure the entire defrost system is working properly.
Q: How often should I replace the defrost heater?
A: Defrost heaters typically last 8-15 years. Replace it only when it fails or shows symptoms of malfunction. It's not a regular maintenance item.
Q: Can I run my refrigerator with a bad defrost heater?
A: Not recommended. Without a working defrost heater, ice will continue to build up on the evaporator coils, eventually blocking all airflow and causing complete cooling failure. Replace the heater as soon as possible to prevent further damage.
Q: Is this a genuine Electrolux part?
A: Yes, this is a genuine OEM Electrolux part (5304522325), manufactured to factory specifications. It's the exact same part a service technician would install, ensuring perfect fit and reliable performance.
