LG Dryer: not running
What is this symptom?
Is your LG dryer not running? If the dryer remains silent when you press the start button, it could be due to various issues such as a power supply problem, door switch failure, or a blown thermal fuse. Understanding these common causes can help you troubleshoot effectively and restore functionality to your appliance.
Important Tips for LG Models
- LG dryers may have a child lock/control lock that prevents start if enabled; check and disable per model instructions.

DIY Solutions
Check Power Supply and Reset Breaker
- Ensure dryer is plugged securely into outlet.
- Check and reset the circuit breaker for the dryer’s dedicated circuit.
- Test the outlet with another device to confirm power availability.
- If the outlet has a switched wall control (e.g., light switch), ensure it is ON.
Verify Door Latch and Door Switch
- Open and firmly close the dryer door listening for a definite click from latch.
- Test the door switch for continuity with a multimeter with door closed.
- If no continuity, replace the door switch.
- Reassemble and test dry cycle.
Replace Thermal Fuse
- Unplug dryer and access the back or blower housing to locate the thermal fuse.
- Use a multimeter to test continuity across the fuse.
- If fuse shows no continuity, remove and replace with exact model part.
- Reassemble dryer and test operation.
Test and Replace Start Switch
- Unplug dryer and open control panel to access start switch.
- Test switch for continuity when pressed.
- Replace switch if no continuity.
- Reassemble and test dryer start.
