A slow heating oven wastes energy and delays cooking. The most frequent cause is a failing heating element or temperature sensor. When elements age, they lose conductivity and cannot reach proper temperatures.
Before calling for repair, ensure the oven is correctly calibrated. Set it to 350°F and use an oven thermometer to check accuracy. If there’s more than a 25°F difference, calibration or sensor replacement may be required.
Gas ovens can heat slowly if the igniter is weak. A faint orange glow without ignition means the igniter needs replacement.
nother reason could be poor ventilation behind the oven. Dust and grease buildup restrict airflow and affect heating efficiency.
