Professional Repair Guide

What is this symptom?

Is your oven not heating to the desired temperature? This common issue can disrupt your cooking experience, causing food to be undercooked. The actual temperature inside may be significantly lower than what is displayed, affecting your meals. Identifying the cause early can help you take the right steps to resolve it.

Urgency: Medium

Possible Causes

Faulty heating element (electric)

How to Identify: Element does not glow red when heating or shows visible damage/breaks when inspected.

Part: Bake or broil heating element

Malfunctioning igniter (gas oven)

How to Identify: Gas oven igniter fails to glow or draw enough current to ignite gas, long flame ignition or no flame.

Part: Oven igniter

Faulty temperature sensor or thermostat

How to Identify: Oven cycles heating irregularly or shows temperature readings inconsistent with an external thermometer.

Part: Temperature sensor/thermostat

Door seal/leakage

How to Identify: Heat visibly escapes around the door; gasket appears worn, compressed, or cracked.

Part: Oven door gasket

Control board or electronic control failure

How to Identify: Displayed temperature settings don’t correspond with actual heating behavior and other components test fine.

Part: Oven control board
