Electrolux Dryer: burned circuit board

Professional Repair Guide

What is this symptom?

If your Electrolux dryer has a burned circuit board, you may notice burn marks, melted components, or a burning smell. This issue can cause the dryer to become unresponsive or shut off mid-cycle, indicating a serious electrical failure that requires immediate attention.

Urgency: High

Important Tips for Electrolux Models

  • Electrolux dryers can develop burning smells and shorted control boards; board itself can short and produce odor and malfunction.

Possible Causes

Control board relay or component failure

How to Identify: Visible burn marks or melted connectors on the board, dryer shutdown, no response when starting, or burnt smell originating from control panel area.

Part: Main control board relay or associated circuitry

Power surge or electrical fluctuation

How to Identify: Board failure shortly after a known surge event, no other failed internal components but visible char on board power supply side.

Part: Control board power supply and circuits

Moisture or overheating due to poor ventilation

How to Identify: Corrosion, moisture traces near electronics, or persistent high internal temperatures due to blocked vents.

Part: Control board and surrounding electronics

DIY Solutions

Visual Inspection and Multimeter Testing Before Replacement

Moderate 30–60 minutes
Tools Needed: Screwdriver set, Multimeter, Camera (for wiring reference)
  1. Unplug the dryer from power and ensure it's fully powered down.
  2. Remove the top or control panel to access the main control board.
  3. Inspect the board for burn marks, melted connectors, or damaged components.
  4. Photograph the existing wiring layout for reference.
  5. Use a multimeter to check for continuity and shorts on heater element and motor circuits.
  6. Check for continuity to ground on heating element and motor to rule out external causes.
⚠️ Safety First: Always disconnect power before accessing internal components.

Control Board Replacement

Advanced 1–2 hours
Tools Needed: Screwdriver, Nut driver, Multimeter (optional)
  1. Disconnect power and remove dryer panels to access the control board.
  2. Document all wiring connections with photos.
  3. Disconnect and remove the burned control board.
  4. Install a matching OEM replacement board and reconnect all harnesses.
  5. Reassemble the dryer panels and restore power for a test cycle.
⚠️ Safety First: Ensure exact part match to model number.

Thorough Electrical Diagnostic and Control Board Replacement

Estimated Cost: $200 - $600

When to Call a Professional

Visible severe burn damage on control board with melted wiring/connectors.
Uncertain root cause after basic testing (possible shorts in heater or motor circuits).
No power to dryer and unresponsive after board replacement.

Preventive Maintenance

  • Clean lint filter after each use: Overheating and reduced airflow that could stress electronics
    Frequency: After every drying cycle
  • Annual vent and exhaust cleaning: Internal heat buildup and moisture near control board
    Frequency: Annually
  • Use heavy‑duty surge protection: Damage from electrical surges
    Frequency: Always when installed
