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

Easy 5-10 minutes
  1. Listen and note when hissing/popping occur (e.g., shortly after door closure or during cooling cycles)
  2. Compare with Electrolux user guide description to confirm these align with normal defrost or refrigerant sounds
⚠️ Safety First: Do not attempt internal disassembly while powered

Ensure proper airflow and installation

Moderate 10-30 minutes
Tools Needed: screwdriver (to adjust leveling feet), level tool (optional)
  1. Check that refrigerator is level and stable
  2. Ensure adequate clearance around the unit for airflow
  3. Clean rear coils of dust/debris to help heat exchange and reduce unnecessary noise
⚠️ Safety First: Unplug before cleaning coils

Common Issues Reported by Users

  • Normal operation during defrost cycle
  • Ice buildup in the evaporator
  • Faulty defrost heater

User Suggested Solutions

  1. 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.

  2. 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.

  3. 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.
