In the next five minutes
Safe first steps, before the call. Nothing here needs a tool.
If you smell gas: don’t touch any switch or plug, leave, then call the gas company or 911 from outside.
No gas smell? Stop the dryer and switch off its breaker, or unplug it if the plug is dry and you can reach it without moving the dryer.
Take a photo of the dryer and any code on the display, without opening anything.
Everything else about this problem
Is it an emergency?
Is an LG dryer that won't start an emergency?
Rarely an emergency. Check the plug, the breaker and any GFCI outlet, and that the door is fully closed and the control lock is off. Stop and call a pro if it keeps tripping the breaker, smells like burning, or runs on gas and you smell gas.
Symptoms & causes
If your LG dryer shows no signs of life, meaning no lights, display, or sounds when attempting to start, the issue likely stems from a lack of power or a critical safety component failure. Common root causes include a tripped circuit breaker, a faulty door switch preventing operation, or a blown thermal fuse designed to protect against overheating. Less common but possible culprits include a defective start button or a main control board malfunction.
Tools & parts
You will need a multimeter for testing electrical continuity and voltage, along with a basic screwdriver set (Phillips and flathead) for accessing internal components. Specific replacement parts might include an LG thermal fuse, an LG door switch or an LG start switch. Always ensure you purchase genuine LG compatible parts for optimal performance and safety.
Safety first
Before performing any inspection or repair, always unplug the LG dryer from its electrical outlet to eliminate the risk of electric shock. Additionally, turn off the corresponding circuit breaker in your home's electrical panel to ensure no residual power is present. Be mindful of sharp edges inside the dryer and wear gloves if necessary to prevent cuts.
When to call a pro
If after checking basic power and safety components, your LG dryer still refuses to start, a professional technician is likely required for checking a control board failure. Complex motor issues, such as a seized motor or a faulty motor relay, often necessitate specialized tools and expertise beyond typical DIY repairs. Extensive wiring harness damage or a short circuit within the main power supply system are also critical issues best handled by a certified LG appliance repair specialist.
Questions people ask
Why won't my LG dryer start but has power to the display?
If the display lights up but the dryer won't start, the most common culprits are a faulty door switch or a defective start button. The door switch must register as closed for the dryer to begin a cycle, and the start button itself might not be making proper contact.
How do I reset my LG dryer if it won't turn on?
To perform a basic reset, unplug the dryer from the wall outlet for at least five minutes, then plug it back in. Also, check your home's electrical panel and reset the circuit breaker dedicated to the dryer, as it may have tripped.
What if my LG dryer makes a humming noise but doesn't spin?
A humming noise without spinning often indicates a problem with the motor or the drive belt. The motor might be trying to start but cannot due to a seized bearing, or the drive belt could be broken, preventing the drum from turning.
