Understanding the Problem
If an LG DVE45B6300C dryer produces no heat or only very low heat, the heating element (the coil assembly that generates the dryer’s heat) is a common culprit. The element can burn out, short to ground, or break where the coil connects to its terminals. Damage may occur gradually (reduced heat) or suddenly (no heat). Before assuming the element is bad, basic checks like ensuring proper electrical supply and a clear exhaust vent are important because restricted airflow or a missing 240V supply can mimic heating-element failure. Diagnosing the heating element requires a visual inspection and simple electrical tests with a multimeter. Disconnect power first. Look for broken coil(s), burned insulation, or visible shorting in the element housing. Use your meter to check continuity across the element terminals and for continuity from the element to ground. An open element (no continuity between terminals) or a short to ground indicates the heating element should be replaced. Also test related safety parts (thermal fuse and high-limit thermostat) because these commonly fail when the element shorts or the dryer has been overheating.
Common Symptoms
No heat or very low heat during cycles; dryer tumbles normally; longer drying times; tripped thermal fuse or dryer stops mid-cycle; visible break or burn marks on the heating coil.
Common Causes
- Broken or open heating coil inside the heating element assembly
- Heating element shorted to the metal housing (ground), causing thermal fuses or thermostats to blow
- Related safety parts (thermal fuse, high-limit thermostat) have failed due to overheating or an element fault

Helpful Repair Tip
Always unplug the dryer (or turn off the breaker for 240V models) before testing. To confirm the element is bad, remove access to the heating assembly and check continuity across the element terminals with a multimeter — a reading of infinite/OL means the element is open and needs replacing. Also check continuity from element terminals to the metal housing to rule out a short to ground.
Frequently Asked Questions
Can I replace the heating element on my DVE45B6300C myself?
Yes — replacing the heating element is a do-it-yourself job for someone comfortable with basic appliance repair and electrical safety. Always disconnect power (turn off the 240V breaker) before starting. Typical steps: remove the dryer’s rear panel or front panel to access the heating assembly, disconnect wiring and mounting screws, remove the old element, install the new assembly, reconnect wiring, and reassemble. If you’re unsure or you don’t have the right tools, hire a qualified technician.
Could something other than the heating element cause no heat?
Yes. Other common causes of no heat include a blown thermal fuse, failed high-limit thermostat, bad cycling thermostat, tripped breaker or missing 240V supply, or a broken wiring connection. Restricted venting or a clogged lint screen can also cause overheating and secondary failures. When diagnosing, check power, venting, and these safety parts in addition to testing the heating element.
