The 4 Most Common Electric Oven Faults

Posted on: 6 October 2014

Electric ovens can be a great addition to your kitchen. They come with a wide range of benefits, including being less expensive and less maintenance. However, as with any electrical appliance they can be prone to faults. Below are four of the most common oven faults you might experience with your electric appliance:

Oven Doesn't Heat Up

Firstly, you have to distinguish between an oven that doesn't heat up and an oven that is completely dead. If your oven is completely dead, then it's likely time to replace. However, if your oven seems to be working but just isn't generating heat, then there are some things you can do to fix it.

If the oven's fan is running properly and the thermostat light is on, then you probably have a faulty heating element. Thankfully, this isn't a major issue and these components can easily be tested and replaced.

Another cause of this problem can be the oven's changeover switch. Typically, oven's are equipped with a changeover switch (commutator) that is used to select the different oven functions. The thermostat is situated behind this on entry level ovens, whereas the thermostat is a separate entity on more expensive models. If these thermostats are in any way damaged, then your oven will not be able to achieve the required temperature.

Oven Heats Up But Cuts Out After Some Time

Any electrical appliance from a place like Arizona Discount Appliance that heats up and then cuts out after some time is usually caused by overheating. There are safety features installed in all appliances that cause the power supply to cut out if the temperature exceeds a certain limit. Typically, overheating itself is caused by a faulty thermostat or safety thermostat. It may also be caused by a damaged cooling fan, however these are typically noticed due to excessive noise prior to failure.

Safety thermostats often go unnoticed, as they are usually buried within the insulation around the oven cavity and their wires are hidden from view. However, these are the critical components that stop any overheating from spiralling out of control. If your oven cuts out, this should be the first component you check. Oftentimes, they simply need replaced which can be carried out by any professional technician.

The Oven is Generating Excessive Noise

Any noise generated by the oven is due to its mechanical parts. Therefore, the first place to start looking is the cooling fan and the motor. Over time, these parts can become damaged and fail to work at their intended speeds. Additionally, the cooling fan motor may become misaligned over time which allows the blades to 'catch' on to the casing as the fan rotates. This can give off an audible rattling sound that will highlight the problem.

Older ovens may be prone to bearing failures in the fan motor. If this isn't addressed reasonably quickly, the fan element may fail as the motor isn't turning quickly enough to keep the oven cool. In some situations, the fan blades may strike the element, causing it to become damaged over time.

Units Either Side of the Oven Are Burning

This problem is typically seen in older ovens where there is a faulty door seal, allowing heat to escape which burns the units either side.

However, this problem can also be seen in newer appliances that have recently been installed. Usually, this is due to a poor installation method that doesn't have adequate ventilation. It may also be caused by an oven that has been installed without allowing additional space between the oven front and cupboard doors. If the units either side of the oven aren't excessively damaged, then the oven simply needs to be taken out and reinstalled in order to remove this issue from occurring.

If you suspect any of the above with your oven, you should contact an electrical technician who will be able to offer professional advice on how to proceed. Many of the issues associated with electric ovens are easy fixes, so your appliance should be back to normal in no time.
