Oven Not Heating? Common Electric Oven Causes and Checks

An oven that stays cold, or heats only a little, is frustrating, especially when the cooktop still works. The cause is often one part, and a few quick checks can tell you whether the problem is the oven or the power feeding it.

This guide covers electric ovens and ranges. Most causes come down to a handful of things: the elements, the temperature sensor, the control board and relays, the breaker, and settings such as a self-clean lock or a delay or Sabbath mode. Gas ovens are different: they need a licensed gas technician, and we repair electric models only.

What you can safely check first

• Confirm it is an electric model. If it uses a gas supply, it needs a licensed gas technician, not us.
• Check the breaker panel. Electric ranges are often on a double breaker, two linked switches. If one half has tripped, the cooktop may work while the oven does not. Switch it fully off and back on once.
• Look at the display and settings. Make sure the oven is in Bake, with a temperature set, and not in a timer-only or delay start mode.
• Check for a Sabbath or Shabbat mode, a control lock or a delay start. Follow the manual to cancel them.
• If the door seems stuck, the self-clean lock may be engaged. Wait for it to finish and cool, then try again.
• Look inside, with the oven cold, at the bake element at the bottom and broil element at the top. Visible blisters, breaks or a burn mark mean the element has likely failed.

Common causes

A failed bake or broil element

The elements are the heating coils. The bake element heats the oven from below and the broil element from above. If an element is broken, the oven may stay cold or heat unevenly. A technician tests it and replaces it if needed.

A faulty temperature sensor

The sensor tells the oven how hot it is. If it reads wrongly, the oven may refuse to heat, shut off early or run too hot or cold. It looks like a thin probe near the back of the cavity, and is tested by a technician.

A control board or relay problem

The control board decides when the elements get power, and relays act as switches. If a relay fails, the oven can appear fine on screen but never heat. Pressing buttons with no response, or odd display behaviour, can also point here.

A tripped or weak breaker

A half-tripped double breaker or a worn breaker can cut power to the oven while the cooktop continues. If the breaker keeps tripping, do not keep resetting it. Call for help.

Self-clean lock and special modes

The self-clean lock, a delay start or Sabbath mode can stop normal baking. These are not faults, but they look like one. Cancelling the mode usually restores heating.

When to call a technician

Call a technician if the breaker is on, the settings are correct and the oven still does not heat. Call at once if a breaker keeps tripping, you see sparks or scorch marks, or you smell burning.

Tell us the model number and what the oven does. We give a price before work starts, and same-day visits are often available.

Still not working? Book a range or oven repair and tell us the model number and what you have checked.
