Common Causes & Diagnosis
Burnt Bake Element (Electric)
The bake element at the bottom of electric ovens can burn out. Look for visible breaks, blisters, or burn marks on the element.
Faulty Igniter (Gas)
Gas ovens use an igniter to open the safety valve and light the burner. A weak or failed igniter prevents the oven from heating.
Faulty Temperature Sensor / Probe
The temperature sensor regulates oven temperature. If it fails, the oven may not heat at all or heat to the wrong temperature.
Faulty Control Board
The electronic control board controls all oven functions. A failed board can prevent the heating elements from receiving power.
Thermal Fuse (Electric)
Like dryers, some electric ovens have a thermal fuse that blows if the oven overheats, cutting power to the heating elements.
