Oven Tripping Electrics

In case your oven trips the Residual Current Device (RCD), fuse or electrics; then you can run several checks that will help you unravel exactly where the problem lies. However, it is important noting that there are more problems not outlined in this post. The issues covered here are the most common ones, which will help you eliminate various possibilities, taking you closer to the real issue(s).

Only trained and qualified technicians may be allowed to work on electrical equipment and we strongly advise you to call a professional electric oven repair engineer.

Before you begin the diagnosis process, ensure you disconnect the appliance from the mains. An earth leakage or dead short is the most common causes of RCD and fuse trips, which may occur each time you switch the appliance on. Working with some appliances, you realise that they trip conditionally; when using specific functions. This should tell you, in most instances, that certain components are faulty, although it might not be so at all times.

Tracking down causes of problems for cookers, hobs and ovens can be quite easy, mostly involving elimination processes and use of common sense. When you see the fuse break the moment you apply power to the connected appliance, you should start examining the wiring system. Ensure that it is sound and correct. Please do not take any action unless you are confident you can do it safely and legally, it’s always best to call a qualified electric oven repair engineer than go it alone.

Next, make sure that the supply is working appropriately, and the appliance is connected in the right manner. Incorrectly placed terminal blocks are a normal occurrence in new appliances. Hob installers also often make the mistake of interchangeably placing the terminals. As you see, most of these problems concern installation, which your manufacturer might charge you for, as they do not fall under their guarantee terms and conditions.

The clock is the next thing using power in cookers and ovens. Being a huge mains switch component, it can trip the cooker or oven at the moment of applying power to a new product. This is not to say that such incidences do not occur with older products, only that they are not very rampant.

If power blows immediately you select a given function in your appliance, it means one of the components is faulty. This depends on which appliance you are using, as various hobs, cookers, and ovens vary in their system setup and component composition. Such an occurrence in a fundamental oven indicates issues to do with parts supplied with energy at the moment of powering on.

Some of the parts of a non-fan (static) oven powered on switching to cooking mode include:

• Cooling thermostat control and fan motor
• Internal lamp
• Oven heating (lower and upper) element
• Thermostat
• Safety thermostats
• Selector switch

For most powering- related problems, the problem often lies in the selector switch, with damage seen in the form of switch poles arcing, burning or scorching. Another issue could be in the elements, which you should check using an earth leak or electrical meter.

When you are not sure of where the problem with your oven is, please be sure to contact an electric oven repair engineer, rather than trying to fix it by yourself. In case the product’s warranty is still applicable, do not hesitate to visit your supplier.
