LG DLEX3570V Dryer Not Heating: Safe Checks and Compatible Parts

Is your LG DLEX3570V dryer running but not heating? Start with the simplest checks: confirm that the selected cycle and heat setting call for heat, clean the lint filter, inspect the exhaust hose and exterior vent for restricted airflow, and verify that the dryer has its required electrical supply. An electric dryer can sometimes tumble while still lacking the complete power supply needed for heat.

If those checks do not resolve the problem, do not assume that one component is automatically responsible. A no-heat, low-heat, intermittent-heat, or slow-drying symptom can involve several parts and conditions, including the heater assembly, thermal cutoff or fuse, thermostat, thermistor, wiring, control components, restricted airflow, or incoming power. The verified fitment information for the LG DLEX3570V Dryer identifies two relevant replacement parts: Heater Assembly part 5301EL1001H and Blower housing exhaust thermostat (high-limit thermostat) part 6931EL3002M.

What should you check first when the LG DLEX3570V dryer has no heat?

Begin with external checks that do not require opening the appliance:

• Check the cycle and heat setting. Confirm that the selected program is intended to use heat rather than an air-only or otherwise non-heating setting.
• Clean the lint filter. A dirty filter can reduce airflow and contribute to poor drying performance.
• Inspect the exhaust hose. Look for crushing, sharp bends, or visible lint accumulation.
• Check the exterior vent outlet. Make sure the outlet is not visibly blocked and that airflow is not obviously restricted.
• Consider the symptom carefully. A dryer with completely cold air has a different symptom from one that produces weak or intermittent heat. A long drying time may point to airflow or heating problems rather than a totally failed heater.

Do not continue using the dryer if you notice burning smells, unusual sounds, visible damage, or signs of overheating. Disconnect the appliance from power and arrange qualified service.

Could the electrical supply allow the drum to spin but prevent heating?

Yes, the symptom can occur when an electric dryer tumbles but does not receive the complete electrical supply required for its heating circuit. Check the appliance connection and household electrical supply only in ways that are safe for you. Do not remove electrical covers or perform energized-voltage testing unless you are qualified to do so.

If the LG DLEX3570V turns on and tumbles normally but produces no heat, electrical supply should remain part of the diagnosis rather than assuming the heater is defective. A qualified technician can verify the supply and the dryer’s internal circuit safely.

Could restricted airflow cause the LG DLEX3570V to dry slowly?

Yes. A blocked lint filter, crushed exhaust hose, or restricted exterior vent can reduce drying performance and may contribute to overheating of heating and safety components. Slow drying does not prove that the heater assembly has failed. Clean and inspect the accessible airflow path first, while following the appliance’s safety instructions.

If airflow is poor even after cleaning, stop relying on part replacement as the first step. The vent system may need inspection or cleaning by a qualified person. Correct airflow is important whether the eventual failed component is a heater, thermostat, thermal cutoff, fuse, or another part.

Which components can create a no-heat symptom?

More than one component can produce similar symptoms on an LG DLEX3570V Dryer. Possible areas for qualified diagnosis include:

• Heating element or heater assembly: A failed heating assembly can result in no heat or reduced heating.
• Thermal cutoff or fuse: A safety device that has opened can interrupt the heating circuit. The cause of the opening should also be considered before installing a replacement.
• Thermostat: A thermostat helps regulate or protect the heating system. The verified model hub lists the blower housing exhaust thermostat, also described as a high-limit thermostat, for this model.
• Thermistor: A sensing problem can affect temperature control and may require testing rather than visual inspection alone.
• Wiring or controls: Loose, damaged, or failed circuit components can interrupt heating even when the dryer still powers on.
• Airflow and power supply: These are not replacement parts in every case, but they can create symptoms that resemble a failed heating component.

Because these causes overlap, replace a part only after its fitment and failure have been appropriately checked. Unplug the dryer before internal inspection. Avoid energized testing unless it is performed by a qualified technician.

Which heater assembly fits the LG DLEX3570V Dryer?

The verified model hub lists Heater Assembly part 5301EL1001H for the LG DLEX3570V Dryer. This is the model-specific heater assembly identified in the supplied fitment data. Review the product information here: LG Dryer Heater Assembly 5301EL1001H.

Before ordering, compare the part number with the label on the existing component when accessible and confirm the full appliance model label. Do not rely on appearance alone; similar dryer components may look alike while having different applications.

Which high-limit thermostat fits the LG DLEX3570V Dryer?

The verified model hub also lists Blower housing exhaust thermostat (high-limit thermostat) part 6931EL3002M for the LG DLEX3570V Dryer. Review the product information here: LG Dryer Blower Housing Exhaust Thermostat 6931EL3002M.

A thermostat-related symptom does not by itself prove that this part has failed. Airflow, overheating conditions, wiring, and other safety components may also need attention. Have the circuit diagnosed before replacement when possible.

Frequently asked questions about an LG DLEX3570V dryer with no heat

Why does the drum spin if the dryer has no heat?

Tumbling and heating involve different portions of the appliance’s systems. The dryer may run while the heating circuit, electrical supply, airflow, or a safety component has a problem.

Should you replace the heater first?

Not automatically. Check the cycle, airflow, and electrical supply first, then have the heating circuit and related safety components tested. A similar symptom can come from several causes.

Can a blocked vent cause intermittent heat?

Restricted airflow can affect drying performance and contribute to overheating conditions. Inspect the lint filter, exhaust hose, and exterior vent before replacing a component.

What should you confirm before ordering?

Confirm the full LG appliance model label, the exact part number, and the product’s listed fitment. For this hub, the verified part numbers are 5301EL1001H and 6931EL3002M.
