What does LG Dryer Won't Stop - Causes & Fix mean?

Usually a faulty door switch or stuck control-board relay. Test the door-latch mechanism, then reset the control and check the switch circuit.

How do I fix LG Dryer Won't Stop - Causes & Fix?

Work through the step-by-step fix below. Start with the quick reset and the most common cause, then check the specific part this guide points to. Most fixes need only basic hand tools and the right replacement part.

Can I keep using my LG appliance with this error showing?

Usually not. LG appliances show this error when a part or safety circuit is out of range, so running it can stop the cycle or make the problem worse. Diagnose and clear the error before normal use.

Is LG Dryer Won't Stop - Causes & Fix a DIY repair or do I need a technician?

Many fixes are DIY-friendly with basic tools, such as door switches, drain pumps, water inlet valves, thermostats, heating elements, and filters. Sealed-system, refrigerant, gas, or high-voltage work should go to a licensed technician for safety.

LG Dryer Won't Stop - Causes & Fix

LG Dryer Won’t Stop — What’s Happening

When an LG dryer won’t stop running, the control board is either not sensing a valid end-of-cycle condition or it has a stuck output that keeps the motor and heating circuit energized. The most common root cause is a door-switch or door-latch problem that prevents the control from correctly reading the door state. LG assigns the code dE to door errors, which means the door is not being sensed as properly closed or the switch circuit is reporting incorrectly.

If the dryer continues to tumble or heat even after the timer expires or you press Stop, the issue often lies with a control-board relay that has welded shut or an input circuit that never registers the stop command. LG’s published troubleshooting procedures recommend a power reset for many control faults, and persistent problems after that reset typically point to wiring damage or a failed main control board.

Most Likely Causes

Faulty door switch or door-switch wiring The door switch fails to report a valid open or closed state, so the control board cannot interpret cycle commands correctly and keeps the dryer running.
Door not fully latched or broken latch mechanism A weak, worn, or misaligned latch prevents the door from closing securely enough to actuate the switch, causing intermittent door-sense failures.
Stuck relay or main control board fault A relay on the control board welds closed or the board logic fails, leaving the motor or heating circuit energized regardless of cycle state.
Loose or damaged wiring harness Broken conductors, loose connector pins, heat damage, or corrosion between the door switch and control board create erratic signals that confuse the control.
Control board reset needed after power interruption A brief power loss or voltage spike can leave the control in a stuck state that requires a full reset to clear.

How to Diagnose and Fix

Verify the complaint by confirming the dryer continues to tumble or heat after the cycle timer reaches zero or after you press the Stop button.
Close the door firmly and inspect the latch strike and mechanism for wear, breakage, or misalignment that would prevent full engagement.
Perform LG’s reset procedure by unplugging the dryer or switching off the breaker, holding the Start/Pause button for five seconds, restoring power, and testing a cycle.
Access the door-switch assembly and test the switch for continuity with the door open and closed, replacing the switch if it does not change state reliably.
Inspect all wiring and connectors in the door-switch circuit and at the control-board harness for loose pins, broken wires, heat damage, or corrosion.
If the switch and wiring test good but the dryer still will not stop on command, replace the main control board.
Reassemble the cabinet and run a complete normal cycle to verify that the dryer starts, stops on command, and responds correctly to door opening and cycle-end signals.

When to Call a Pro

Call a technician if the reset procedure and door-switch checks do not resolve the problem, or if you are uncomfortable working with the 240 V power supply that feeds most LG dryers. Control-board diagnosis and replacement require safe disassembly of live circuits, and a misdiagnosis can lead to expensive unnecessary parts. Professional service is also recommended if you find evidence of arcing, melted connectors, or repeated board failures, since those symptoms often indicate a larger electrical fault in the home circuit or dryer wiring harness.
