Electrolux Refrigerator: hissing and popping
What is this symptom?
Experiencing intermittent hissing and popping noises from your Electrolux refrigerator? This often occurs during normal operation, particularly near the rear coils or during temperature changes. While some sounds are typical, understanding their source can help you maintain your appliance's performance.
Important Tips for Electrolux Models
- Electrolux documentation explicitly lists hissing/sizzling during defrost and popping after defrost as normal operating sounds
Possible Causes
Normal defrost cycle and refrigerant flow sounds
How to Identify: Occurs several times daily, often during or after defrost cycle or when cooling cycles change; not accompanied by performance issues
Part: Defrost heater / evaporator and refrigerant lines
Refrigerant circulation noise
How to Identify: Steady or intermittent hissing especially when compressor is active; no temperature drop or error codes
Part: Refrigerant tubing / evaporator coils
Thermal expansion and contraction
How to Identify: Popping/clicking when temperature changes occur (e.g., compressor cycling on/off without other faults
Part: Metal interior walls and components
DIY Solutions
Verify normal operation timing
- Listen and note when hissing/popping occur (e.g., shortly after door closure or during cooling cycles)
- Compare with Electrolux user guide description to confirm these align with normal defrost or refrigerant sounds
Ensure proper airflow and installation
- Check that refrigerator is level and stable
- Ensure adequate clearance around the unit for airflow
- Clean rear coils of dust/debris to help heat exchange and reduce unnecessary noise

Can I Fix This Myself?
Common Issues Reported by Users
- Normal operation during defrost cycle
- Ice buildup in the evaporator
- Faulty defrost heater
User Suggested Solutions
-
Monitor the sounds during the defrost cycle; they are typically normal. If they persist or worsen, check for ice buildup. Ensure the refrigerator is level and the vents are not blocked.
-
Inspect the evaporator for ice buildup. If ice is present, manually defrost it and check the drain for clogs. Ensure proper airflow by cleaning the vents.
-
Test the defrost heater for continuity using a multimeter. If it is faulty, replace it. This may require disassembling parts of the refrigerator.

hissing and popping sounds from freezer vent
The sounds are normal and occur when the evaporator is defrosting, as water from melting frost hits the defrost heater.
