LG Dryer Heating Element Replacement — Diagnosing No-Heat Problems

The heating element in an LG electric dryer is a coiled resistance wire inside a metal housing that heats air as the blower pulls it through the drum. When the element burns out, the dryer tumbles normally but produces no heat — clothes come out damp after a full cycle. This is the most common repair on LG electric dryers and one of the more straightforward fixes.

Gas LG dryers do not have a heating element — they use a gas valve and igniter instead (covered in the igniter replacement guide).

How the LG Dryer Heating Element Fails

The resistance wire inside the element housing is under constant thermal stress — it heats to red-hot during operation and cools between cycles. Over years, the wire develops thin spots, sags, and eventually breaks. When the wire breaks, the circuit opens and no current flows. The dryer tumbles but produces cold air.

A less common failure mode is the wire sagging until it contacts the metal housing, creating a ground fault that trips the breaker or blows the thermal fuse.

Restricted exhaust vents accelerate element failure by causing the element to run at higher temperatures for longer periods. LG dryers with d80 or d90 vent codes are telling you the exhaust is restricted — fix the vent before the element burns out prematurely.

Confirming It Is the Element

Before buying the element, check the complete heating circuit in order. Each component is cheaper and faster to test than the element:

1. Thermal fuse — one-shot device, $8-$20. Test continuity. No continuity = blown. Most common cause of no-heat. But find out what blew it (usually a clogged vent).
2. High-limit thermostat — safety cutoff, $12-$35. Test continuity. If open, reset or replace.
3. Cycling thermostat — regulates temperature, $10-$30. Test continuity when cold — should be closed.
4. Heating element — $25-$80. Test continuity across the two terminals. Expected reading: 10-20 ohms. Infinite = open (burned out). Also test from each terminal to the housing (ground test) — any reading means a grounded element.
5. Control board relay — if the relay that switches the element is burned, the element gets no power even though it tests good.

Part Numbers and Pricing

Tools Required

• Phillips #2 — for rear panel access
• 1/4 inch nut driver — for element housing mounting screws
• Multimeter — essential for testing the element and the entire thermal circuit chain
• Needle-nose pliers — for disconnecting the wire terminals on the element

Replacement Steps

Disconnect power (240V — both breaker poles). Remove the rear panel (typically 8-12 Phillips screws). The heating element housing is a metal can mounted vertically on the rear bulkhead.

Disconnect the 2-3 wire terminals from the element housing. Remove the mounting screws (2-4 screws, 1/4 inch or Phillips). Pull the housing out. The old element may be removable from the housing (held by ceramic insulators and clips), or the entire housing assembly may need replacement depending on the part format.

Install the new element/housing, reconnect wires, and reassemble the rear panel. Run a timed dry cycle for 10 minutes — you should feel hot air at the exhaust vent and inside the drum.

The Vent Restriction Connection

A clogged or kinked exhaust vent is the primary cause of premature element failure and blown thermal fuses. When exhaust airflow is restricted, the heating element runs hotter and longer because the drum temperature takes longer to reach the thermostat setpoint. This accelerates wire fatigue.

LG dryers display d80, d90, or d95 codes when the vent flow sensor detects restriction. These are warnings, not errors — the dryer continues to operate. But ignoring them leads to element burnout, thermal fuse failure, and increased fire risk.

After replacing the element, always check and clean the exhaust vent. A $30 vent cleaning prevents a repeat element replacement in 1-2 years.

Frequently Asked Questions

My LG dryer has no heat but tumbles fine. Is the heating element bad?

Possibly, but test the thermal fuse first — it is the most common no-heat cause and costs $8-$20. If the fuse is good, test the element continuity. Infinite resistance = burned out element.

Can a clogged vent cause the LG dryer heating element to fail?

Yes. Restricted exhaust forces the element to run hotter and longer, accelerating wire fatigue. If your LG dryer shows d80/d90 vent codes, clean the vent immediately to prevent premature element burnout.

Is the LG dryer heating element covered by the 10-year warranty?

No. The 10-year warranty covers only the Direct Drive motor. The heating element is covered under the standard 1-year parts and labor warranty.
