When the oven’s self-cleaning function is not working, instead of quickly and safely cleaning the inside surface from grease, food leftovers, and maybe other small debris, you have to spend more effort and time doing it by hand. Sounds familiar? Then you are in the right place. Below we will describe the main reasons why the self-cleaning function may not work, and also give recommendations for repair and diagnostics.

Reasons Why Oven Self-Cleaning Function Not Working

with Online Application
Door Lock Malfunction
For the self-cleaning function to start and work properly, the oven door must be securely closed and locked. If the lock is broken or not working correctly, the cleaning mode will not start because of the built-in safety system. This is made to prevent damage to electrical components and also possible burns.
Solution
- First check if the door is closing tightly.
- Then visually inspect the lock for mechanical damage.
- If the lock jams or is defective, it must be replaced.
- Remember that the new part should be original.
Temperature Sensor Failure
During self-cleaning, the function of the temperature sensor is to control the oven’s heating. If the sensor is not working correctly or fails, the cleaning process will not start, because the control board receives wrong data.
Solution
- If you have a multimeter and know how to use it, remove the sensor and measure its resistance with the device.
- Find the manual for your oven and compare the results with the numbers in the instructions.
- If you find a mismatch, replace the sensor with a new one.
- And remember, the part should be original for the proper operation of the whole appliance.
Pro Tip: Never start the self-cleaning mode with a faulty sensor — it is dangerous and can cause overheating.
Control Board Issues
The control board, or controller, is like the brain of the oven. It ensures the operation of all oven functions, including start and control. Self-cleaning is also included in this list. You can detect a board failure by signs like buttons not responding to certain commands, or the cleaning function simply not starting.
Solution
- Start inspection and repair only if you have professional experience.
- The first step is to check for visible damage.
- Look for traces of moisture, burned sections, or damaged components.
- If you suspect a fault, the board must be replaced.
Pro Tip: It is very important when working with such equipment as ovens to disconnect it from the power supply. Replacing the board is quite a complex and delicate procedure, better to contact an experienced technician.
Blown Thermal Fuse
The thermal fuse cuts off electricity to the heating elements when overheating occurs. If the fuse is blown, the self-cleaning function will not start, because the oven considers the system unsafe.
Solution
- Check the thermal fuse with a multimeter for circuit continuity.
- If it is blown, replace it with a new one.
Power Supply Problems
In working mode, the self-cleaning function of the oven must be supported by stable voltage. Problems like weak connection, grounding issues, or power surges can prevent self-cleaning from starting.
Solution
- t is important to check the outlet, cord, and plug for integrity.
- Next step, measure the voltage with a multimeter.
- If necessary, contact a qualified electrician to fix network issues.
Pro Tip: The oven consumes a lot of energy, so we recommend not to use extension cords or power strips when turning on the self-cleaning mode. This can be dangerous.
Repair Cost
| Door lock replacing | $160-$260 |
| Temperature sensor replacing | $180-$290 |

How often does the oven’s control board fail?
Hi David! Control boards rarely fail on their own. Issues usually come from power surges, moisture, or overheating. With proper use and stable power, a control board can last 8–12 years.
Can a control board be repaired, or is it always replaced completely?
Hi Lucas! It depends on the damage. In some cases, a technician can replace individual parts like capacitors or relays. But most of the time, repairs are more expensive or less reliable than installing a new board, so replacement is usually the better option.
How long does it usually take to repair the self-cleaning function?
Hi Joshua! The repair time depends on the exact issue. Simple problems like replacing a door lock or thermal fuse can often be fixed within 1–2 hours. More complex issues, such as diagnosing and replacing a control board, may take longer—sometimes half a day if parts need to be ordered. In many cases, if the necessary parts are in stock, a same-day repair is possible.
