Electrolux Dryer: clogged heat exchanger

Professional Repair Guide

What is this symptom?

Is your Electrolux dryer struggling to dry clothes efficiently? A clogged heat exchanger may be the culprit. This common issue, caused by lint and dust buildup in the condenser assembly, restricts airflow and heat transfer, leading to longer drying times. Regular maintenance can help prevent this problem and keep your dryer running smoothly.
