The electric oven switches itself off

Your electric oven just switches itself off? We will explain why your device is malfunctioning. There are various potential causes behind the problem you're experiencing. In this diagnosis, we invite you to check the components in the order in which they are listed.

POTENTIAL CAUSES OF THIS FAULT:

• The timer is incorrectly configured

• The power supply is faulty

• The terminal block is damaged

• Safety klixon (safety thermostat) in safe mode

• A switch contact is faulty

• The cable, Terminals or Internal wiring are defective

• The electronics module is faulty

WARNING
Before carrying out any work on your appliance, be absolutely sure to first completely disconnect it from the mains electricity supply.
Risk of electric shock.
Wear protective gloves if you need to disassemble the appliance.
Risk of cuts and abrasions.

The timer is incorrectly configured

The problem operating your oven may simply originate from an operating fault in the timer: timer set to too short a time? You can easily remedy this situation by setting a sufficient cooking time.

The power supply is faulty

If your oven switches off by itself, it is possible that the power supply is responsible. If the appliance switches off while in operation, first check that the fusible fuse has not been tripped and that the circuit breaker for your electrical system has not been triggered. Also check that the current is reaching the oven's plug socket. To do this, simply connect another appliance to the plug socket. If you have a multimeter, you can also use it to test the status of your socket. If you observe that your electrical socket has signs of burning or that the plastic appears to be melted, it is highly probably that the socket has suffered a false contact, which may explain the fault with your oven. You will then have to replace the wall socket and the oven plug. If you do not know how to change the wall outlet, we advise that you to call an electrician. Does your oven have connection terminals rather than a plug? It is necessary to check both the condition of the wires and the tightness of their connection to the component. Insufficient tightening or a broken wire can cause your oven to stop unexpectedly.

The terminal block is damaged

The oven's terminal block brings together all the electrical wiring necessary for the proper function of the appliance. It is usually located at the back, at the bottom of the oven, and has a cover. If this component is faulty, your oven will malfunction, for example by switching off by itself. Generally speaking, you can easily inspect the condition of this part by sight. If one of the wires is damaged or burned, you will have to repair it by cutting the wire, then stripping it back and finally connecting this stripped section to the correct terminal on the block. If this is not possible, you will have to replace the terminal block.

Safety klixon (safety thermostat) in safe mode

The safety thermostat is the component that is triggered when your oven experiences overheating (caused by a fault with the ventilation or even the regulation of the adjustable thermostat). If the safety thermostat is activated, then the oven will no longer be able to start a heating programme. This is usually located on the top or rear panel of the appliance (the top or rear panel must be removed). To check the safety thermostat, use a multimeter or tester set to Ohmmeter (Ω) mode: place the two probes of the tester onto the terminals of the thermostat (be sure to disconnect all connectors before doing so). There must be continuity (there must be a value). If not, it will have to be replaced.

A switch contact is faulty

On oven models referred to as mechanical, the switch, also known as the programme selector, may prove to be the part responsible for the oven switching off involuntarily. The purpose of the switch is to supply power to the various oven components (i.e. resistors and fans) according to the selected cooking mode. If one of the connectors on the switch is disconnected, damaged or has been cut, this may stop proper voltage flow and thus prevent the oven from firing. Access the programme selector by removing the top panel of the oven, and perform a visual inspection of the condition of the component. If the switch is faulty, it will have to be replaced.

The cable, Terminals or Internal wiring are defective

If not due to a part, it is generally possible that an oven may function unreliably on account bad of a bad contact: one or more wires within your appliance may be broken, burned or even cut. Similarly, a terminal or connector may have become oxidized or damaged. You must therefore check their condition. To do this, you can remove the top and back panels on your oven and manipulate the visible wires and connectors. If you find a damaged wire or connector, repair it immediately. However, if repair is not possible, it will have to be replaced.

The electronics module is faulty

You have verified all of the above and everything is in order? Unfortunately, the circuit board may be faulty and can cause the oven to shut down. It will then have to be replaced. However, you must remain attentive, as if the problem is related to another defective component in your appliance (sensor, fan motor or the like), the new circuit board may react in the same way!
