The DLEX3370W heating element fails more often than most homeowners expect — usually around the 5-7 year mark when lint buildup restricts airflow and overworks the element. Our technicians see this model weekly across LA and know exactly what signs to look for before the element burns out completely.

LG DLEX3370W Heating Element Replacement & Repair Service

LG DLEX3370W Heating Element Cost Breakdown

The OEM heating element for your DLEX3370W runs $180-220 depending on current LG pricing. Labor typically takes our techs 45-60 minutes at $95/hour, bringing total repair cost to $320-370. We only use genuine LG parts — never aftermarket knockoffs that fail within months. Nine times out of ten, we find the thermal fuse has also blown when the heating element goes bad, adding another $25 for the part. Most repair shops in Pasadena quote higher because they mark up parts 40-50%, but we keep markup minimal since volume purchasing gives us better LG wholesale pricing.

What's Included in Our Heating Element Service

Our techs always test the thermal cutoff, high limit thermostat, and cycling thermostat when replacing the element. The first thing we check is lint buildup in the exhaust vent — a clogged vent causes 70% of heating element failures. We clean the entire lint pathway and test airflow before installing the new element.

Signs Your DLEX3370W Heating Element Needs Replacement

Clothes taking 2-3 cycles to dry completely is the classic first symptom — the element is weakening but hasn't failed entirely. Our technicians know the DLEX3370W produces very little heat when the element starts going bad, unlike older models that either work perfectly or not at all. You might notice the drum getting warm but clothes staying damp, especially heavier items like jeans or towels. The dryer will run its full cycle but everything comes out slightly damp or room temperature. Most homeowners don't realize the heating element can partially fail — they assume it's either working or completely broken.

Advanced Diagnostic Signs Our Techs Look For

We test continuity across the heating element coils with a multimeter. A reading of infinity means the element has an open circuit and needs replacement. Sometimes the element housing cracks from repeated heating cycles, causing intermittent failures that are harder to diagnose without proper testing equipment.

Compatible Models for DLEX3370W Heating Element

The same heating element works across multiple LG DLEX series models from 2016-2019, including DLEX3370V, DLEX3370R, and DLEX3700V. However, never assume compatibility without checking the exact part number — LG changed suppliers twice during production and element specifications vary slightly. Our techs carry the most common versions but always verify against your model's serial number plate. The DLEX3370W uses either part number 5301EL1001J or AEX73110002 depending on manufacturing date. Most online retailers sell aftermarket elements that look identical but use cheaper alloy wire that overheats quickly.

Why OEM Elements Last 3x Longer Than Aftermarket

LG engineers the element coil thickness and resistance specifically for the DLEX3370W's airflow patterns and temperature sensors. Aftermarket elements often run too hot or too cool, confusing the dryer's computer and causing premature failure of other components like thermostats and fuses.

DIY Installation vs Professional Service Comparison

Replacing the heating element requires removing the entire front panel and disconnecting multiple wire harnesses — definitely not a 20-minute YouTube project. Our techs see plenty of DIY disasters where homeowners damaged the door seal, broke plastic clips, or wired the element incorrectly. The element assembly sits behind the lint filter housing and requires removing 8-12 screws plus plastic clips that break easily if forced. Most homeowners underestimate the disassembly required and end up calling us anyway after getting halfway through. Don't try to save $150 in labor if you're not completely comfortable with appliance wiring — one crossed wire can fry the control board.

Tools and Time Requirements for DIY Approach

You'll need a multimeter, socket set, plastic pry tools, and at least 2-3 hours even if everything goes perfectly. The heating element housing bolts are often seized from heat cycles, requiring penetrating oil and patience. We've rescued several DIY attempts where homeowners stripped screws or cracked the plastic drum housing trying to force stuck components.

Preventive Maintenance to Extend Heating Element Life

Clean your lint trap after every single load — seems obvious but most families skip it occasionally, and that's enough to shorten element life by 2-3 years. Our technicians find that dryers in Thousand Oaks with hard water develop mineral buildup in the moisture sensor, causing over-drying that burns out elements faster. Check your external vent monthly for lint blockage, especially if it exits through the roof. A partially blocked vent makes the heating element work 40% harder to maintain temperature. Replace plastic transition hoses with rigid metal ducting — plastic hoses sag over time, creating lint traps that restrict airflow and overheat the element.

Warning Signs of Vent Problems Before They Kill Your Element

If your laundry room feels humid or hot during dryer operation, the external vent is probably blocked. We find bird nests, lint buildup, or damaged vent flaps cause 60% of premature heating element failures. A simple vent cleaning every 18 months prevents most element replacements.

Frequently Asked Questions

How much does it cost to replace an LG DLEX3370W heating element?

Total cost runs $320-370 including the OEM LG element and labor. We charge $95/hour for labor and the job typically takes 45-60 minutes. The genuine LG heating element costs $180-220 depending on current pricing. Most shops charge more because they mark up parts heavily, but our volume purchasing keeps costs reasonable.

Can I replace the heating element in my DLEX3370W myself?

It's technically possible but requires complete front panel removal and careful wire harness disconnection. Our techs see plenty of DIY attempts that end up costing more when homeowners break plastic clips or damage the door seal. If you're not completely comfortable with appliance wiring and have 3+ hours available, we'd recommend professional installation.

How do I know if my LG dryer heating element is broken?

Clothes taking 2-3 cycles to dry completely is the classic sign. The dryer runs its full cycle but everything comes out damp or barely warm. Sometimes the element partially fails, producing some heat but not enough to properly dry loads. Our techs test continuity with a multimeter — infinite resistance means the element has an open circuit and needs replacement.

How long does an LG DLEX3370W heating element typically last?

With proper maintenance, expect 7-10 years from the original element. However, lint buildup and vent blockages can cut that to 4-5 years by making the element work harder. We see elements fail as early as 3 years in homes with poor vent maintenance or frequent overloading of the dryer.

What tools do I need to replace an LG dryer heating element?

You'll need a multimeter, socket set, plastic pry tools, and penetrating oil for seized bolts. Plan on 2-3 hours minimum even with experience. The heating element sits behind the lint filter housing and requires removing the entire front panel plus multiple wire harnesses. Many bolts are heat-seized and require patience to remove without stripping.
