Error codes
| Code | What it means |
|---|---|
| F9 | Oven not reaching temperature within the expected time |
| F1 | Oven temperature sensor fault |
| F19 | Control board fault |
| F3 | Key stuck on the control panel |
Tech notes
F9 means the oven failed to reach temperature in time, that is an element, a relay or a sensor, and it is worth measuring all three before ordering. On a range this age the element is the most likely of the three, and by far the cheapest to prove.
