To troubleshoot your LG dryer, follow a systematic process to identify airflow, heating, mechanical, or electronic issues. First, check for error codes on the display: d80, d90, d95 means 80 to 95 percent vent blockage, clean the vent; tE means temperature sensor error; LE means motor overload. Second, verify power: for electric dryers, ensure the 240-volt double breaker is not half-tripped and the outlet provides 240 volts; for gas, ensure gas supply is on and 120-volt outlet works. Third, check airflow: clean lint filter before every load, vacuum lint housing below filter, pull dryer out and check flexible duct for kinks, go outside and ensure exterior flap opens fully when dryer runs, and clean wall duct annually. Fourth, test heat: run Time Dry on high heat for 2 minutes, open door and feel if drum is warm; if not, likely thermal fuse, heating element, igniter, or gas valve issue requiring service. Fifth, check load size: do not overload beyond 75 percent and ensure clothes are tumbling, not balled up. Sixth, clean moisture sensors: wipe two metal bars inside drum with rubbing alcohol to remove fabric softener residue that causes early shutoff. Seventh, reset: unplug dryer for 10 minutes, press Start for 5 seconds, plug back in. If problems persist, call LG support with model number.
