If your dryer doesn’t start on command it doesn’t always call for a replacement or even a repair. Why is my LG dryer not starting? If the Child Lock setting is enabled, all control panel functions will be locked. Use these LG dryer troubleshooting tips to determine the source of the problem when it won’t start on command.
Why Is My LG Dryer Not Starting?
While an LG dryer not starting usually has a quick fix, it’s also important to specify if a part failure is responsible. Here’s how to identify the problem and determine if professional assistance is needed.
#1- Check the Power Source
Checking power sources should be the first step in troubleshooting starting issues. Without adequate and consistent power, an LG dryer doesn’t turn on and the display panel and interior light don’t illuminate. In some cases, the dryer takes forever to dry due to reduced or restricted voltage.
Use these tips to assess power issues:
- Check the power cord: Make sure it’s plugged into a working outlet and is free of damage. A frayed or ripped cord must be replaced.
- Look for tripped breakers: Reset tripped breakers, if necessary. If none of the breakers are tripped, turn off the dryer’s breaker. Wait 5 seconds and turn it back on to see if power is restored.
- Avoid extension cords: These cords can’t reliably transmit the voltage needed, leading to surges that interrupt power.
#2- Child Lock is On
If your LG dryer won’t start but has power, check to see if the Child Lock setting is engaged. This feature locks all control panel settings to prevent an accidental start. When engaged, the letters “CL” illuminate on the control panel, and no other functions will respond.

To disengage this setting, press and hold the Child Lock button for 3 seconds. “CL” should disappear from the control panel and other settings should respond to commands.
#3- LG Dryer Door Not Latching Correctly
As a safety precaution, an LG dryer won’t start a drying cycle if the door isn’t closed and latched. Always close the door firmly to ensure that the latch clicks, signifying that it’s engaged. Is your LG dryer not starting even if the door is closed properly? The latch may be faulty. If it appears damaged or fails multimeter testing with no continuity, the latch must be replaced.
Pro Tip: Avoid slamming the dryer door shut. Doing this can cause damage to the door latch over time. Instead, be sure to close it gently to prolong the life of the latch.
#4- LG Dryer Start Switch Not Working
What does it mean if my LG dryer won’t start when I push the start button? If the above issues aren’t to blame, the start switch could be broken. This switch is typically located behind the POWER/PAUSE button, under the display panel. When the start button is pushed, the switch signals the dryer’s control board to start a drying cycle.
If the switch is broken, the dryer won’t start or make any noise. To confirm failure, test the switch for continuity with a multimeter. If there’s no continuity, it requires replacement.
#5- Defective Thermal Fuse
Lastly, if you find your LG dryer not turning on, the thermal fuse may be defective. When working properly, the thermal fuse blows when the dryer is in danger of overheating, safeguarding against additional part failures. However, the fuse can also blow if it’s faulty. In either case, the dryer won’t resume any function until the fuse is replaced.
Before assuming that the fuse is defective, check the lint trap and dryer vent for clogs that restrict airflow, potentially causing overheating. If there are no blockages, a defective fuse is likely responsible for your LG dryer not starting and must be professionally replaced.
