Understanding the Problem
The LG LEQ9858LG dryer can present several common failures: it may not heat, fail to tumble, make unusual noises, or take much longer to dry than normal. Many of these issues are caused by a few repeat culprits — clogged vents/filters, failed heating components, worn drive components (belt, rollers, motor), or electrical/control failures. Proper diagnosis saves time and money because multiple symptoms can look similar but have very different fixes. Start with the simplest checks: verify power/gas supply, clean the lint filter and exhaust vent, and confirm the dryer settings and load size. If basic checks don’t fix it, use a multimeter and a few safe mechanical inspections to isolate failed parts (thermal fuse, heating element/igniter/thermal cutouts, motor, belt, drum rollers, door switch, control board/relay). For gas models, check the igniter and gas valve coils; for electric models, check the heating element and high-limit thermostats. Always disconnect power (and gas for gas dryers) before working on the unit.
Common Symptoms
Dryer doesn't heat; runs but won't tumble; drum turns intermittently; unusually long dry times; loud squealing or thumping noises; dryer trips breaker or blows thermal fuse.
Common Causes
- Clogged or restricted exhaust vent or lint filter restricting airflow and causing long dry times or thermal cutouts
- Failed heating component (electric heating element or gas igniter/valve) or blown thermal fuse/thermal cutoff
- Worn drive components (belt, idler pulley, motor) or bad drum rollers causing no tumble or excessive noise

Helpful Repair Tip
Before replacing parts, confirm failure with a multimeter: check continuity of the thermal fuse, heating element/igniter, thermostats and motor windings. Also measure line voltage at the dryer terminal block for electric dryers (240V) or verify the gas valve receives proper signals on gas models.
Frequently Asked Questions
How can I tell if my LG LEQ9858LG dryer heating element (or igniter) is bad?
For an electric dryer: unplug the dryer, access the heating element assembly and test for continuity with a multimeter. A broken element or open thermal fuse will show no continuity. Also inspect visually for a broken coil. For a gas dryer: check the igniter for continuity and observe whether it glows briefly when starting (with gas on and venting safe). If the igniter fails or the gas valve coils do not receive voltage, the burner won't open. Also confirm proper voltage at the terminal block (electric) or that the gas supply and gas valve are functioning (gas).
Can I replace parts myself or should I call a technician?
Many replacements (lint filters, belts, drum rollers, thermal fuses, heating elements, igniters, door switches) are user-serviceable with basic tools and following safety steps: unplug the dryer (and shut off gas for gas models), consult the service manual/parts diagram for your LEQ9858LG, and follow step-by-step instructions. However, if you’re uncomfortable with electrical measurements, gas components, or control board diagnostics, or if the repair requires extensive disassembly, call a qualified appliance technician. Always confirm the correct OEM part number for your exact model tag before ordering.
