Electrolux Dryer: moisture sensor broken

Professional Repair Guide

What is this symptom?

Is your Electrolux dryer failing to detect moisture in clothes? This can lead to overdrying or underdrying, random cycle ends, and error messages. The issue may stem from a contaminated moisture sensor, wiring connection problems, or sensor hardware failure. Identifying the cause is crucial for restoring optimal performance.

Urgency: Medium

Important Tips for Electrolux Models

  • Electrolux dryers place moisture sensor bars inside drum; buildup from fabric softener or lint can impair detection; wiring should connect each bar correctly.

Possible Causes

Moisture sensor contamination (residue buildup)

How to Identify: Sensor bars inside drum show visible residue or fabric softener film; incorrect dryness detection

Part: Moisture sensor bars

Wiring connection issue at sensor

How to Identify: Dryer shows inconsistent moisture detection without visible contamination; wiring misconnection noted in community expert case

Part: Moisture sensor wiring harness

Sensor hardware failure (open/failed element)

How to Identify: Dryer repeatedly misreads moisture and cleaning doesn’t help; testing with multimeter shows no expected resistance change (diy.

Part: Moisture sensor assembly

DIY Solutions

Clean moisture sensor bars

Easy 10-20 minutes
Tools Needed: soft cloth, mild cleaner or rubbing alcohol
  1. Disconnect and unplug dryer.
  2. Locate moisture sensor bars inside the drum near the door opening.
  3. Wipe sensor bars with soft cloth and mild cleaner to remove residue.
  4. Allow to dry and run test cycle to check improvement.
⚠️ Safety First: Always unplug dryer before cleaning sensors.

Test moisture sensor electrical continuity

Advanced 20-40 minutes
Tools Needed: multimeter, screwdriver set
  1. Unplug dryer and access sensor wiring area.
  2. Disconnect sensor and measure resistance across sensor bars with multimeter.
  3. Compare readings to manufacturer‑spec values to determine if sensor is open/failed.
  4. If readings are abnormal, plan for replacement.
⚠️ Safety First: Unplug unit before internal access; electrical measurements require care.

Professional Repairs

Replace moisture sensor assembly

Estimated Cost: $30 - $100 (part)

When to Call a Professional

Sensor cleaning/testing doesn’t correct moisture detection issues
Wiring or board accessibility problems
Sensor assembly replacement unfamiliarity

Preventive Maintenance

  • Regularly clean moisture sensor bars: Moisture sensor misreads due to residue buildup
    Frequency: monthly
  • Clean lint filter after each use: General drying issues that can mimic sensor problems
    Frequency: after every cycle
