Electrolux Dryer: intermittent fan operation

Professional Repair Guide

What is this symptom?

Experiencing intermittent fan operation in your Electrolux dryer? This issue manifests as fluctuating airflow, with the fan sometimes blowing strongly and at other times weakly or not at all. Such irregular performance can lead to inefficient drying cycles and frustration during use.

Urgency: Medium

Important Tips for Electrolux Models

  • Official Electrolux troubleshooting documentation covers general dryer performance issues but does not explicitly document intermittent fan operation; community and general dryer repair resources must be referenced instead

Possible Causes

Airflow restriction due to lint buildup or vent blockage

How to Identify: Drying is slow and airflow feels weak; lint visible in filter or vent; intermittent airflow coincides with filter/vent state.

Part: Lint filter, internal ducts, external vent

Blower wheel or fan obstruction/damage

How to Identify: Audible changes in airflow, unusual sound; intermittent airflow even with clean lint path. Fan blades may be obstructed.

Part: Blower wheel / fan assembly

Control or relay issue affecting fan power

How to Identify: Fan cuts in/out with cycle stage; dryer may display control errors; other functions may also operate erratically.

Part: Control board / relay / wiring

Fan motor wear or overheating protection triggering

How to Identify: Fan starts then stops; may restart after cool‑down; unusual noise from motor.

Part: Blower fan motor
