F02 in plain terms
F02 means there may be a problem with the oven temperature sensor, the control or the wiring between them. Ovens often bake unevenly for a while before this code appears, so treat F02 as the end of a slide in temperature accuracy and stop relying on the oven until the sensor circuit is checked.

What you see with F02
- F02 after weeks of uneven baking — Burnt edges, pale tops or longer cook times came first.
- An oven thermometer disagreeing with the display — The gap grows as the sensor drifts further.
- The code at higher settings only — A sensor that drifts most when hot can stay in range at low settings.
- Normal behaviour after a reset, for a while — The control accepts the reading again until it strays back out.
Causes of F02, ranked
- A drifting oven temperature sensor — First: slow drift before the code fits a sensor wearing out better than any other cause.
- The control misreading a good sensor — Second here: a failing input on the control can also drift, though less often.
- A connector with rising resistance — Third: corrosion on the terminals adds resistance slowly, which the control reads as temperature.
- Damaged wiring — Last in this pattern: wiring faults tend to be sudden rather than gradual.
What to check first for F02
- Compare an oven thermometer with the setpoint — Needs nothing but the thermometer, and shows whether the drift is real.
- Reset and see how quickly F02 returns — A quick return means a sensor well out of range; a slow one, a marginal sensor.
- Measure the sensor against the tech sheet chart — With the power off and the sensor unplugged, it confirms the drift.
- Test the control's input and the wiring — Only if the sensor reads true.
What an owner can safely do about F02
- Run a thermometer check — Place an oven thermometer on the centre rack, bake at a moderate setting, and compare once the oven has settled.

- Reset the control — Breaker off for a minute, then on.
Tools: breaker panel accessAbout 3 min
- Do not lean on the temperature offset — Many controls let you adjust the displayed temperature; it can mask a drifting sensor but cannot fix a failing one.
Tools: owner's manualAbout 5 min
- Measure or replace the sensor — Power off: unplug the sensor and compare its reading with the chart; replace it with the part for your model number if it is out.

Safety before you start
Safety
Unplug the range or switch off its breaker before removing the sensor or any panel; a capacitor can hold a charge after the power is off. Stay with the oven during thermometer tests, because a sensor reading low lets the oven run hotter than set. On a gas range, if you smell gas, do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside.
When to book a service call for F02
Call if the sensor measures true on the chart but the thermometer still disagrees with the display, or if F02 returns quickly after a new sensor. Those point to the control's input or the wiring, which need live testing.

What this reading does not cover
This reading of F02 applies to Amana ovens whose control reports the oven temperature sensor circuit with this code, as the table states. Other Amana controls report the same circuit in other formats, and where a model-specific page exists, it is the better answer. None is listed for F02 yet; the Amana oven code index below is the starting point.
