LG: Not Heating
If the oven stays cold or preheat stalls, we first confirm whether bake, broil, or both are missing heat. That split points to elements/igniters, sensing faults, thermal limits, or relay output problems.

Learn more →Most gas ovens that fail to ignite have an igniter that glows but cannot pull enough amperage to open the gas valve under load.
Learn more →Slow preheat or low bake temperature usually comes from weak heat output, sensor drift, or control calibration faults rather than one generic bad part.
Learn more →Uneven baking and hot spots usually point to convection airflow problems, weak heating zones, or temperature sensing drift.

Typical fix: Replace temperature sensor or repair harness.
Meaning: Heating Error (not reaching temp)
Typical fix: Test elements/igniter; inspect control output.
Most jobs fall into the $129-$219 labor range. The technician confirms the exact failure during the $39 diagnostic.
Some symptoms are safety-related. If you’re unsure, stop using the unit until a technician confirms the cause.
