F2 / F20
- What the machine is reporting
- The oven exceeded its safe temperature and shut down.
- What puts it there
- The temperature sensor reading low so the control keeps heating, or a relay on the control board that has welded closed. Those two are very different bills and a sensor test separates them in minutes.
- What it usually costs
- Most oven & range jobs land between $150 and $400, parts included, and the $150 minimum service call is part of that rather than on top of it. This one lands anywhere in it — the same code covers a rinse-out and a part.
- True for
- GE ranges and wall ovens with an electronic control.
