No Heat
LG Oven
Severity:What Does This Error Mean?
An LG oven that won't heat usually has a burned-out bake element, a blown thermal fuse, or a faulty temperature sensor preventing the heating cycle from starting. Check the circuit breaker first, then inspect the bake element for visible damage.
Affected Models
- LG Electric Range
- LG Gas Range
- LG LRE Series
- LG LRG Series
- LG Studio Range
Common Causes
- Failed bake element (most common on electric models)
- Blown oven thermal fuse
- Faulty temperature sensor preventing heating cycle from starting
- Tripped circuit breaker on 240V supply
- Failed igniter (gas models)
How to Fix It
-
Check the circuit breaker.
Electric ovens run on 240V — a single tripped breaker leg can power the display and fan but leave the heating element without power. Locate the oven's breaker and reset it fully.
-
Inspect the bake element visually.
Look at the coil at the bottom of the oven cavity (with the oven off and unplugged). A cracked, blistered, or burned element with a visible hole must be replaced — these signs confirm failure.
-
Test the bake element with a multimeter.
Disconnect the element wires and test for continuity. No continuity means the element has burned out internally even if there is no visible damage. LG bake elements cost $20–$60.
-
Test the oven temperature sensor.
A faulty sensor (open circuit) tells the control board the oven is already hot, so no heat is requested. Test at room temperature — should read ~1,000 ohms. Replace if the reading is open circuit.
When to Call a Professional
If the element, thermal fuse, and sensor all test correctly, the control board is likely not sending power to the heating circuit. A technician can confirm this with a wiring diagram and multimeter.
