Oven Won’t Turn On
When you’re ready to cook a delicious meal or bake your favourite dessert, the last thing you want is to find that your electric oven won’t turn on. This can be a frustrating experience, but don’t worry – there are several common causes for this issue, and many of them can be resolved with a bit of troubleshooting. In this blog post, we’ll guide you through the steps to diagnose and fix the problem.
Understanding How Electric Ovens Work
Before we dive into the potential issues, it’s important to understand how electric ovens work. Unlike gas ovens, which primarily operate using 120 volts of alternating current, most electric ovens require 240 volts of alternating current running through two legs of voltage (each carrying 120 volts).
The first leg of voltage is usually regulated by the oven control. The second leg of voltage may also be regulated by the control or it may be continuously present at one side of the bake element and broil elements. When you select the bake or broil function, the oven control allows either the first leg of voltage or both legs to travel to the bake or broil element, closing the circuit and causing the element to heat up.
A sensing bulb on the oven thermostat, or an oven sensor, monitors the temperature in the oven, and when the selected temperature is reached, the oven control will shut off the voltage to the element. This cycle is repeated throughout the baking or broiling process to maintain the proper temperature. If this process fails, then the electric oven won’t heat up.
If you need to test an electrical component when making your repairs, more often than not, you will need a multimeter. You can pick one up over on Amazon https://amzn.to/46GUUzp
Common Causes of an Electric Oven Not Turning On
Power Supply Issues: The first thing to check when your electric oven won’t turn on is the power supply. Make sure the oven is properly plugged in and that there’s no issue with your home’s electrical supply. If your home recently experienced a power outage or if you’ve been having issues with your circuit breaker, these could be the cause of the problem.
Faulty Oven Control Board: The oven control board regulates the oven’s heating elements. If it’s not functioning correctly, it could prevent the oven from turning on. While the board cannot be easily tested, you can always inspect it for signs of burning or a shorted-out component.
Broken Heating Elements: The heating elements in your oven are responsible for cooking your food. If they’re broken or burnt out, your oven won’t heat up. You can often determine that an element has burned out by simply inspecting it for visible breaks or blistering. You can also use a multimeter to test the element for continuity – a continuous electrical path present in the part. If the element tests negative for continuity then it is defective and will need to be replaced.
Faulty Oven Sensor: The oven sensor plays a crucial role in regulating the oven’s temperature. If it’s not working correctly, it could prevent the oven from turning on. When testing the sensor at room temperature, the meter should display approximately 1,100 Ohms of resistance. If the resistance is significantly off, the component should be replaced with a new one.
Damaged or Loose Wiring: Over time, the wiring in your oven can become damaged or loose, which can prevent the oven from turning on. You should confirm the wires are free of damage and that the wire connection is secure.
Blown Thermal Fuse: On some electric oven models, a thermal fuse will blow if the oven gets too hot, shutting off the power to the oven. As with the elements, you can use a multimeter to test the fuse for continuity to determine if the component needs to be replaced.
