(SOLVED) Why does my Oven keep Turning OFF?

Why does my oven keep turning OFF by itself?

Your oven keeps turning OFF by itself due to a faulty temperature sensor, a malfunctioning door switch, a defective control board, or a blocked ventilation system.

  • Faulty temperature sensor 
  • Malfunctioning door switch
  • Defective control board
  • Blocked ventilation system


Faulty temperature sensor

If the temperature of the oven isn’t as high as required, the temperature sensor permits the passage of power through the heating elements into the oven. This increases the internal temperature of the oven. A faulty sensor can shut the oven OFF. You can resolve this issue by replacing it yourself with the help of the manual or getting a certified oven repair service personnel to assist with the same.


Malfunctioning door switch

A malfunctioning door switch can cause electrical issues and damage your oven. If the door switch has developed a minor defect, you can easily replace this yourself. If it is damaged beyond repair, you can get it replaced by placing an order with the authorized dealer.


Defective control board

A defective control board can result in your oven shutting OFF intermittently. A simple reboot of the control board helps overcome this problem. You have to turn OFF the circuit breaker of the oven for about 3-4 minutes and then switch it ON.


Blocked ventilation system

Constant usage tends to block the various vents which enable the passage of airflow to cool the oven. When they accumulate debris, the passage of air gets blocked causing your oven to overheat and switch OFF randomly. You should clean these vents regularly to ensure your oven works flawlessly at all times. 


Repairing an oven that keeps turning off


How do I stop my oven from turning OFF?

You can stop your oven from turning OFF by ensuring the vents are kept clean at all times, the heating elements are consistently well-maintained or the oven switches and dials are protected from damage.

These types of problems need constant attention and can be easily resolved by following a few instructions given below.


Keep the vents clean at all times

  1. Unplug your oven from the electric power supply outlet.
  2. Use a hand vacuum to remove the debris from the vents or a soft cloth to wipe the layers of accumulated dust. You can also dip a soft cloth in lukewarm soap solution to clean the vents.
