Lg Dryer: not running consistently

Professional Repair Guide

What is this symptom?

Is your LG Dryer not running consistently? This issue often manifests as the dryer starting a cycle but stopping mid-way, regardless of load size. Common causes include overheating due to restricted airflow and issues with the thermal fuse, moisture sensors, or electrical components. Understanding these problems can help you troubleshoot effectively.

Urgency: Medium

Important Tips for Lg Models

  • Small loads may cause early cycle ends because moisture sensors don’t detect enough tumbling contact, potentially interpreted as dryness

Possible Causes

Overheating due to restricted airflow

How to Identify: Dryer stops mid‑cycle with prolonged running times, feels unusually hot, airflow weak at external vent

Part: Venting/airflow system (lint filter, vent ducts)

Thermal fuse blown due to overheating

How to Identify: Dryer stops and won’t restart even with correct settings; continuity test shows open circuit

Part: Thermal fuse

Moisture sensor issues causing premature cycle end

How to Identify: Dryer ends early particularly with mixed‑thickness loads; sensor residues visible

Part: Moisture sensor assembly

Electrical/control board or timer malfunction

How to Identify: Stops inconsistently without signs of overheating; other parts tested good

Part: Control board / timer

Power interruption / supply issues

How to Identify: Dryer turns off mid‑cycle and won’t restart unless breaker reset or power restored

Part: Electrical supply/circuit

Common Issues Reported by Users

  • Faulty door switch preventing the dryer from running when the door is not securely closed.
  • Overheating due to clogged vents or lint filter, causing the thermal fuse to blow and stop the dryer.
  • Malfunctioning control board that fails to send power to the motor intermittently.

User Suggested Solutions

  1. Check and test the door switch for continuity using a multimeter. If faulty, replace it.

  2. Inspect and clean the lint filter and venting system to ensure proper airflow. Replace the thermal fuse if it has blown.

  3. Test the control board for any visible damage or burnt components. If necessary, replace the control board.
