What to do
- Note the code and stop
There's no home fix. Don't use the machine until it's repaired.
When to call an engineer
Now. There's no reset or home fix for a failed temperature sensor.
A repair visit will usually check the sensor's reading with a meter, then its wiring.
Before you book
- Note the model and serial number. They're on a label inside the door, around the door frame or on the back.
- Write down the exact code, and what the appliance was doing when it appeared.
- Check whether it's still under warranty. If it is, the repair may cost you nothing.
