When troubleshooting electric stoves there are a number of things that you will need to consider. There are lots of problems which can occur with a stove. If a single burner doesn't work on top of your stove, then it suggests that this is a problem related to the single burner rather than problems related to the entire device.
Removing the Element
There are two different types of elements which are commonly used on electric stoves. These are plug-in or direct-wired elements. Replacing plug-in elements will be much easier and these can also be removed for easier inspection. The element can be pulled out and the connections can be inspected. If there is any damage to the connections then the entire element will need replacing.
When removing a direct-wired element, you should first pull the element up and then use a screwdriver to open the white porcelain connector which is located towards the back of the element.
Re-seating the Element
The elements are the components which actually heat up the stove and make cooking possible. If these elements move or are lifted there could be problems. Try re-seating the elements back in the top of the cooker and check that they are connected properly. These elements need to be connected to the wires so that they will be able to turn on properly.
After re-seating the element, try turning on the element again to check whether or not this has fixed the problem. If not, you will need to do some further research. Sometimes simply pushing the burner back into position will be enough to fix the problem.
Testing the Element
If the element is damaged or broken, it could be the cause of the problem. To test it, disconnect the element from the oven and remove it. Then use a multimeter to check that the element is not broken. To do this easily, set the multi-meter to measure resistance. The resistance of the element should be 20 to 40 ohms. If the element is any higher, this suggests that there is some form of problem with the element itself which will need investigating.
Checking the Wiring
There could also be a number of problems which can affect the wiring of your cooker. As only one burner is affected this will not be the entire wiring of your electric stove but only the internal wiring. If you are experiencing problems with the single burner, then you will need to check the wiring. If you're not able to do this yourself, you should consider hiring a professional to help you.
The elements on all stoves can be replaced if needed. It is important to check that they are replaced with the correct type of element for your stove.
