LG oven not heating F9 code repair in Atlanta GA

When your LG oven not heating and displaying F9, it’s warning that it didn’t reach 150°F or more within the preset time. In short — the oven isn’t heating up fast enough. You may notice that the oven feels warm but never gets hot enough to cook, or it takes far longer than usual to preheat.

This fault is common in Atlanta homes with LG gas ranges that use an electronic igniter, as well as in electric models that rely on dual heating elements.

🔧 Top Causes of LG Ovens Not Heating (F9 Error)

If your LG oven won’t heat, one of these components is likely at fault:

  1. Weak or faulty igniter (gas ovens) – The igniter glows but isn’t hot enough to ignite gas.
  2. Burned-out heating element (electric ovens) – The bake or broil element may be open or shorted.
  3. Defective temperature sensor – The oven’s thermistor may be misreading the internal temperature.
  4. Relay or control board failure – Power isn’t being sent to the heating circuit.
  5. Loose or damaged wiring – Voltage drops or burnt connectors can interrupt heating.

A professional technician can quickly test these parts using a multimeter and pinpoint which one failed.

🏠 Quick Tips for Homeowners Before Calling for Service

Before you schedule a repair:
