An oven that will not heat, heats slowly, or cannot reach the selected temperature may have an issue with its power supply, heating element, igniter, temperature sensor, thermostat, control, or gas ignition system.
The display, light, and controls can still work even when the oven's heating system has failed. Gas and electric ovens use different components to produce heat, so the likely causes depend on the appliance type.
Electric ovens commonly rely on bake and broil elements, temperature sensors, relays, wiring, and electronic controls. A failed heating element may show visible damage, but electrical testing is often required to confirm the cause.
Gas ovens commonly use an igniter and burner assembly. A weak or failed igniter can prevent the safety valve from opening properly, resulting in no heat or very slow preheating. Sensors, controls, and gas-valve components may also require diagnosis.
If the oven produces heat but cooks unevenly or stays below the selected temperature, the issue may involve a temperature sensor, calibration problem, heating element, igniter, airflow, or electronic control.
If the oven still does not heat after checking the cooking mode, temperature setting, breaker, and accessible gas supply, professional diagnosis is recommended. Cannon Appliance provides oven repair throughout Redwood City and the San Francisco Peninsula.
