If your cooker oven is not heating up properly, it may be time to change the element. The element is responsible for heating the oven, so if it's not working properly, your oven won't be able to reach the desired temperature. Changing the element is a relatively simple repair that you can do yourself, as long as you have the right tools and a replacement element.

Before you start, it's important to turn off the power to the oven and let it cool down. You'll also want to gather the following tools:

• Screwdriver
• Wire stripper
• Pliers
• Replacement element

Once you have all your tools and the replacement element, you can begin the repair process:

1. Remove the oven door and the back panel. This will give you access to the element.
2. Disconnect the wires from the element. Use the wire stripper to remove the insulation from the ends of the wires.
3. Remove the element from the oven. Depending on your oven, you may need to remove screws or clips to do this.
4. Install the new element. Attach the wires to the new element, then attach the element to the oven.
5. Reassemble the oven. Replace the back panel and the oven door, and turn the power back on.
6. Test the oven. Turn the oven on and set it to a high temperature to make sure the element is working properly.

Changing a cooker oven element is a simple repair that can save you money by avoiding the need for professional service. Just be sure to follow these steps carefully and use caution when working with electricity. If you're not comfortable with this repair, it's best to call a professional for help.
