Understanding the Problem
If your LG DLGX7601WE dryer is tumbling but not producing heat, the problem is usually in the dryer’s heating path rather than the motor or drum. Common culprits include a failed heating element, a blown thermal fuse or thermal cutoff, faulty thermostats or thermistors, or an incomplete power supply (missing one 120V leg on a 240V electric dryer). Restricted venting can also cause poor heating even when the element is working. Diagnosing the issue requires basic electrical checks (voltage at the terminal block) and continuity tests on the heating element, thermal fuse, and thermostats. Start with the thermal fuse and heating element — they’re the most common failed parts. If those test good, check the cycling and high-limit thermostats, the thermistor, and the control board or power supply. Always disconnect power before opening the dryer and use a multimeter for continuity and voltage checks.
Common Symptoms
Drum turns but no heat or very little heat; very long dry times; clothes come out damp; no burn smell or clicking; dryer may trip breaker or fuse if element is shorted.
Common Causes
- Blown thermal fuse or thermal cutoff — opens if the dryer overheats
- Open or shorted heating element assembly
- Faulty cycling thermostat, high-limit thermostat, or thermistor
- Missing one hot leg (incomplete 240V supply) or bad power cord/terminal connection
- Restricted venting or lint-clogged exhaust causing overheating and tripping of safety devices

Helpful Repair Tip
First check that the dryer has full 240V power at the terminal block (two 120V legs). Then unplug the dryer and test continuity of the thermal fuse and heating element with a multimeter — a blown thermal fuse or an open heating element is the most common cause.
Frequently Asked Questions
How do I test the thermal fuse and heating element?
Unplug the dryer. Locate the thermal fuse (usually on the blower housing or near the heating assembly) and the heating element. Use a multimeter set to continuity/ohms. A good thermal fuse will show near zero ohms (continuity); a blown fuse shows open (OL). For the heating element, check continuity across the element terminals — an open reading means the element is failed. Also inspect the element for visible breaks or burn spots.
Can a clogged vent cause no heat or long dry times?
Yes. A severely restricted vent can cause the dryer to overheat and trip safety devices (like the thermal fuse) or reduce heating efficiency, resulting in long dry times or no heat. Always check and clean the lint screen, interior lint trap, and the exhaust vent to the outside before replacing parts.
