LG Range HE Error Code - Oven Heating Checks

⚡ Quick Answer

LG range HE error guide for ovens that will not heat, including reset, bake element, igniter, temperature sensor, wiring, and control-board checks.

⚡ AT A GLANCEScroll down for full repair guide
What it meansLG range HE should be treated as an oven heating fault until the model service sheet confirms the exact code wording.
Most likely causeCommon no-heat causes are a weak gas bake igniter, burned electric bake element, failed oven temperature sensor, damaged harness, poor supply voltage, or control relay fault.
First checkReset the breaker once, test a normal bake cycle, separate gas from electric symptoms, inspect the igniter or bake element, then test the sensor and wiring before pricing the board.
⏱Repair time10-20 minutes for reset and visual checks; 45-90 minutes for igniter, element, sensor, wiring, or control diagnosis.
🔧Part neededLG gas oven igniter, bake element, oven temperature sensor probe, range control board, and model-specific wiring.

Parts to price first

Check the part before you book service.

LG gas oven igniter

Common for gas LG ranges when the igniter glows weakly or never opens the gas valve.

LG oven bake element

Relevant for electric LG ranges with visible element damage or no bake heat.

LG oven temperature sensor probe

Use when temperature readings are out of range or the oven overheats/underheats.

LG range oven control board

Price only after the element, igniter, sensor, wiring, and supply voltage check good.

$120-$350 Check price

An LG range HE message should be handled as a heating-fault warning until the model manual confirms the exact code wording. On most no-heat complaints, the fault path is the same: reset once, confirm the oven is getting power, then test the igniter or bake element before blaming the control board.

Quick Triage

Range typeFirst likely partWhat you will notice
Gas rangeBake igniterIgniter glows weakly, burner stays off
ElectricBake elementElement is blistered, cracked, or cold
EitherTemperature sensor probeOven temperature is far off target
EitherControl board or relayLoads test good, but no output power

Step-by-Step Fix

  1. Turn the range off at the breaker for five minutes.
  2. Restore power and start a normal bake cycle at 350°F.
  3. If the display clears and the oven heats normally, watch the next few cycles.
  4. If the code returns, turn power off again before opening any panels.
  5. On a gas range, watch the bake igniter. A weak glow with no flame usually means the igniter is failing.
  6. On an electric range, inspect the bake element for blisters, cracks, or open spots.
  7. Test the oven temperature sensor at room temperature. Many oven sensors read near 1080 to 1100 ohms, but confirm the model service sheet.
  8. Check harness plugs for heat damage, loose terminals, or pinched wires.
  9. Price the control board only after the heating load and sensor circuit test correctly.

When to Call Service

Call an appliance technician if the range is hardwired, the breaker trips, the oven has burn marks behind the panel, the gas burner does not light safely, or live voltage testing is needed. Ranges use high voltage and gas connections, so stop if the checks move beyond visual inspection and plug-in part replacement.

Quick FAQ

What does HE mean on an LG range?

Treat HE as a heating-related warning until you confirm the exact model manual. Start with a breaker reset, then check whether the bake element, gas igniter, temperature sensor, or control relay is stopping the oven from heating.

Can I reset an LG range HE code?

Yes. Turn the range off at the breaker for five minutes, restore power, and test a normal bake cycle. If HE returns or the oven will not heat, stop resetting and diagnose the heating circuit.

What part usually fixes an LG range that will not heat?

Gas LG ranges often need a weak bake igniter. Electric LG ranges often need a bake element, temperature sensor, wiring repair, or control board after the power supply checks good.
