If your DELONGHI oven keeps switching off while cooking, it can make it very difficult to rely on.
It may start heating normally, then suddenly cut out without any clear reason.
This type of issue is quite common and usually indicates a problem with the internal electrical control of the oven.
What could be causing this issue?
1. Worn selector switch
The selector switch controls the oven’s different cooking modes. Over time, the internal contacts can wear down, causing the power to cut in and out.
👉 Common signs:
- The oven stops working during cooking
- It comes back on after turning the knob
- The issue becomes more frequent over time
On DeLonghi ovens, contact burnout on the selector switch is a well-documented fault. Models in the DEF905 series are reported with internal contacts that degrade over time and lose connection intermittently — causing the oven to switch off unexpectedly during cooking before sometimes coming back when the function knob is turned.
2. Internal wiring fault
Damaged or loose wiring can interrupt the electrical supply, leading to sudden shut-offs while the oven is in use.
3. Control system issue
A problem with the thermostat or control components can also result in unstable performance and unexpected shutdowns.
If your DELONGHI oven behaves like this, it’s very likely that one of these components needs replacing.
