Understanding the Problem
If your LG LEQ9858LG tumbles but doesn't produce heat (or takes very long to dry), the cause is usually either a failed heating component, a safety cutoff (thermal fuse/thermostat), or airflow restriction. Electric dryers rely on the heating element and several thermostats/thermal fuses to generate and regulate heat; when any one of these fails the unit will tumble but not heat. Poor venting or a clogged lint screen can also prevent hot air from circulating and cause long dry times. To fix the issue you want to systematically rule out airflow problems first, then check the safety cutoffs (thermal fuse and high-limit thermostat) and the heating element assembly. Finally, if those components test good, verify the control/timer and incoming power. Working methodically reduces parts swaps and gets the dryer back to normal faster.
Common Symptoms
Drum tumbles but no heat; very long drying cycles; clothes warm only near the exterior vent; dryer trips breaker when on heat cycle.
Common Causes
- Blown thermal fuse or failed high-limit thermostat (safety cutoffs)
- Open or shorted heating element assembly
- Restricted airflow (clogged lint screen, vent hose, or external vent) or faulty blower

Helpful Repair Tip
Start by confirming airflow — run the dryer on air-only (no heat) and place your hand at the exterior vent; weak airflow points to a clogged vent or blower. Then test the thermal fuse for continuity with a multimeter (no continuity = replace).
Frequently Asked Questions
How do I test the thermal fuse and heating element?
Unplug the dryer first. Locate the thermal fuse (usually on the blower housing or exhaust path) and the heating element (inside the rear panel or front lower service panel). Remove the part, then use a multimeter set to continuity or resistance. A thermal fuse should show continuity; if it’s open (OL), it’s blown and must be replaced. The heating element should show continuity between its terminals (and no short to the element housing). If the element is open or has shorts, replace it. Always confirm the exact part location from your model’s service manual.
Can I replace these parts myself and how much will it cost?
Yes — many homeowners can replace thermal fuses, thermostats, and heating elements with basic tools. Always disconnect power first. Cost: thermal fuses and thermostats are inexpensive ($10–$40); heating element assemblies commonly run $30–$120 depending on supplier; control boards and motors are pricier ($100–$300+). If you’re unsure about high-voltage diagnostics or the replacement procedure, hire a qualified appliance technician.
