Why Won't My Oven Turn O

Jul 25, 2023, 22:15pm

If your oven does not turn on, that is to say that no indicator lights up, you will need to check several elements.

To determine the part causing the problem, you must first check if your device is responsible for the failure.

  • First of all, it will therefore be necessary to see if the fault comes from your electrical panel or from the socket before checking the oven. If all the fuses are functional and the power outlet is live, then the following items should be checked:
  • Check the oven power supply terminal block
  • Check the oven noise filter
  • Test the thermal safeties of the oven
  • Test the electronic power board supply.

If you’ve encountered a situation where your oven won’t turn on, it’s understandably a cause for concern. However, this issue can stem from various sources, some more serious than others. This article aims to address the common causes behind an oven that won’t turn on and possible solutions.

Disclaimer: Always ensure your safety before attempting any troubleshooting or repair by disconnecting the oven from the power source. If your oven is under warranty or you are uncomfortable performing any of these tasks, contact a professional technician.

Why Won't My Oven Turn On

1. Power Supply Issues

An oven requires a steady power supply to function. Check if the plug is securely connected to the wall socket and the circuit breaker hasn’t tripped. If your oven uses gas, make sure the gas supply valve is fully open.

2. Faulty Igniter (Gas Ovens)

For gas ovens, the igniter is a crucial component that helps light the gas burner. A failing or broken igniter may be unable to ignite the gas, resulting in the oven not turning on. The igniter may require a replacement if it’s faulty.

3. Defective Heating Elements (Electric Ovens)

In electric ovens, the heating elements are responsible for generating the heat required for cooking. If these components are faulty, your oven may not turn on. Inspect the elements for any visible signs of damage. If you find signs of blistering or breakage, it’s time for a replacement.

4. Faulty Thermostat

The thermostat controls the temperature inside the oven. A faulty thermostat may prevent the oven from turning on. If the thermostat isn’t functioning correctly, it may need to be replaced or recalibrated.

5. Broken Timer

Many modern ovens feature built-in timers. If the timer is set or malfunctioning, it could prevent the oven from turning on. Make sure that the timer is off or reset it to see if that resolves the problem.

6. Problems with the Control Board

The control board is the oven’s ‘brain,’ coordinating various functions like temperature regulation and cooking time. If the control board is malfunctioning, it may not send the necessary signals for the oven to operate, preventing it from turning on. In this case, the control board might need a replacement, which is usually a task for professionals due to its complexity.


  • Some models of ovens may be equipped with a thermal protection device, which is activated in case of abnormal overheating. These fasteners, as a rule, are located on top and are attached to the body of the furnace, they can have a different shape.
  • Unplug the oven, remove the back and top panels, and disconnect the thermal protection connectors.
  • Set the multimeter to the continuity function or lower resistance range.

Connect the multimeter leads to the two thermal protection pins: you should read a non-zero numerical value close to zero. If your multimeter does not beep or displays 1 or OL, it means the thermal has sheared and therefore needs to be replaced.

In conclusion, there are numerous reasons why your oven might not turn on, ranging from simple fixes like ensuring the power supply to more complex issues like replacing a faulty control board. If you’ve tried the solutions suggested and your oven still won’t turn on, it’s time to call in a professional. Always remember, safety comes first when dealing with electrical appliances.
