LG Dryer Not Heating in the Twin Cities

Same-Day LG Repair

An LG dryer that tumbles but won't get hot is usually one of five parts, and we carry common ones on the truck. Electric (DLE / DLEX) failures cluster on the heating element and thermal cutoff; gas (DLG / DLGX) failures cluster on the gas valve coils and igniter.

Quick answer

LG Dryer Not Heating: the short answer

LG electric dryers (DLE, DLEX) lose heat from a failed heating element, a tripped thermal cutoff (which protects against a clogged vent), a failed thermistor, a control board relay, or a tripped half-leg of the 240V supply. Gas LG dryers (DLG, DLGX) lose heat from failed gas valve coils, a worn igniter, a tripped thermal cutoff, or a faulty flame sensor. We diagnose in order and never just swap the element, because a clogged vent that tripped the cutoff is the most common cause we find, and replacing the element without clearing the vent can burn out the new one. Most repairs land $215–$385 all-in. The flat $149 trip fee is credited toward the repair when you approve it, and repairs carry a 1-year warranty.

Common causes

Common failures

1. Clogged dryer vent tripped the thermal cutoff (most common root cause)

What it is: On both electric and gas LG dryers, restricted airflow makes the high-limit thermostat or thermal cutoff (one-time fuse) open to protect the cabinet from fire. The dryer still tumbles but never heats. A clogged vent plus a tripped cutoff is the most common cause of an LG no-heat call.

Fix: Clear the full vent run (lint, bird nest, kinked transition), replace the OEM thermal cutoff and high-limit, verify temp rise. Skipping the vent clear means the new cutoff trips again in 2–4 weeks.

Typical all-in: $215–$345 all-in

2. Failed heating element (electric DLE / DLEX)

What it is: The 240V heating coil burns out — usually at the coil-end where it touches the insulator. Tests open on a multimeter. Common at year 6–10 on hard-running LG electric units.

Fix: Replace the OEM heating element, and replace the thermal cutoff and high-limit with it because a failed element often follows a tripped cutoff. Inspect the blower wheel for lint blockage and verify temp rise.

Typical all-in: $245–$385 all-in

3. Failed gas valve coils (gas DLG / DLGX)

What it is: Igniter glows but the gas valve never opens (or opens then drops out) — the coils on top of the gas valve have failed. Symptom: igniter glows orange for 60 seconds then shuts off, dryer runs cool. Common at year 5–8.

Fix: Replace OEM gas valve coil kit, verify gas valve opens and flame sustains, test temp rise.

Typical all-in: $245–$365 all-in

4. Worn or open igniter (gas DLG / DLGX)

What it is: Silicon-carbide igniter has fractured or aged open. Symptom: no glow at all, no burner ignition, dryer tumbles cool.

Fix: Replace OEM igniter, verify glow and flame establishment.

Typical all-in: $215–$315 all-in

5. Failed thermistor or control-board heat relay

What it is: The thermistor reads drum temperature; if it shorts or opens the control board cuts heat to protect the load. Less commonly, the heat-circuit relay on the main board has failed welded-open or open.

Fix: Check thermistor resistance with the power off, then replace the OEM thermistor or main control board as confirmed.

Typical all-in: $245–$425 all-in

Diagnostic order

How to diagnose an LG dryer that won't heat

  1. 1. Safety first

    Unplug the dryer or switch off its breaker (and close the gas shutoff valve on a gas dryer) before removing any panel. If you ever smell gas, leave the house, do not touch switches or flames, and call your gas utility or 911 from outside, then call us. Resistance tests and panel work are for a technician.

  2. 2. Check the breaker (electric)

    A half-tripped 30A double-pole breaker gives you a dryer that tumbles (120V) but won't heat (240V). Switch the breaker fully off, then back on. That is a free fix if it is the cause.

  3. 3. Check the vent for restriction

    Disconnect the vent at the wall and run a Timed Dry on High for 5 minutes. Strong, hot airflow at the wall = vent is OK. Weak / cool airflow = vent is the failure.

  4. 4. Test the thermal cutoff and high-limit

    With the dryer unplugged, a technician pulls the back panel and tests the thermal cutoff (one-time fuse) on the heater housing. Open = blown by vent restriction. Replace it and clear the vent.

  5. 5. Test the heating element (electric)

    With power off and the leads disconnected, a technician reads resistance across the element: a reading means it is intact, open means it is burned out. Replace the element.

  6. 6. Test gas valve coils (gas)

    A technician watches the igniter: glows then no flame points to bad coils, no glow points to a bad igniter. Coil kits and igniters are OEM parts we stock.

FAQs

LG Dryer Not Heating: FAQs

Why won't my LG dryer heat but it still tumbles?

Most often a clogged vent that tripped the thermal cutoff, or a burned-out heating element (electric) / failed gas valve coils (gas). Tumble runs on 120V; heat needs 240V (electric) or working gas valve + igniter (gas). Repair lands $215–$385 all-in.

How do I know if it's the heating element or a vent problem?

Disconnect the vent at the wall and run High heat for 5 minutes — if airflow comes out hot, the element is fine and the vent was the problem. If still no heat, the element or thermal cutoff has failed. We always do a vent test before replacing a heating element because a clogged vent burns out a new element in weeks.

How much does LG dryer no-heat repair cost in Minneapolis?

Most LG no-heat repairs are $215–$425 all-in. Vent / thermal-cutoff $215–$345, heating element kit $245–$385, gas valve coils $245–$365, igniter $215–$315, thermistor / control board $245–$425. The $149 trip fee is credited toward the repair when you approve it.

Why does my LG dryer heat for a few minutes then stop?

On gas units, that's a classic gas-valve-coil failure — igniter glows, valve opens briefly, then drops out. On electric units it's usually a marginal thermal cutoff cycling on a partly restricted vent. Both are single-visit fixes.

Do you service LG WashTower and stacked units?

Yes. LG WashTower units (WKEX / WKGX series) use the same heating system as the standalone dryers. We carry the door panel removal tools and the OEM parts. Stacked installations may need extra time to access the unit.

Do you carry OEM LG dryer parts on the truck?

Yes — heating elements, thermal cutoff kits, gas valve coils, igniters, thermistors, blower wheels, drum belts, and the most-failed LG main control boards are stocked across DLE, DLG, DLEX, DLGX, and WashTower.
