The short answer
On a Maytag oven, F02 points at the temperature sensor circuit. The exact documented wording is in the table; the order of the checks below it is the part worth reading twice. It is usable if it still holds temperature; stop if it overshoots or cuts out.
The documented code and its meaning
Reference| Code | Meaning |
|---|---|
| F02 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you actually observe
- Temperatures run high or low against the setting — A drifting sensor shows up in the cooking or drying result weeks before the code does.
- Results are uneven from one use to the next — An intermittent reading gives an intermittent result.
- The fault followed a period of heavy or unusually long use — Thermal cycling is what ages both the element and its plug.
- NEAR MISS — no heat at all, ever — That is a heating-circuit or supply question and it belongs elsewhere.
Causes, most likely first on this oven
- The sensing element drifting out of band, or going open — Resistance elements drift rather than snap, so the appliance usually cooks or dries badly for weeks before the control finally rejects the reading.
- A corroded or loose connector at the sensor plug — It is the hottest and dampest connector in the circuit, and that is why the plug beats the element to failure so often.
- Insulation worn where the sensor loom passes the cavity wall — The grommet at the wall is where the insulation wears, and a conductor touching metal reads as a short to the control.
- The control board input that reads the sensor — Genuinely uncommon: the input stage on the board outlives the sensor and its wiring by a wide margin.
Check in this order, and why
- Establish whether it faults cold or only once hot — A cold fault points at the wiring and the plug; a hot one points at the sensor itself.
- Ask a technician to read the sensor resistance at room temperature — One resistance reading at the plug separates element, wiring and board in a single measurement.
- Have the sensor plug examined for corrosion and heat damage — Corrosion or heat damage at the plug is the cheapest finding in this family and among the most frequent.
- Treat the board as the last suspect, not the first — Board last: everything ahead of it is both likelier and cheaper.
What an owner can safely check
- Power the unit down at the breaker for a minute and restore it — Sometimes a stored fault goes for good; an immediate return means it is live.
About 3 min
- Set down the temperature behaviour of recent weeks — Uneven results in the weeks beforehand are the history that actually helps here.
Tools: pen and paperAbout 5 min
- Stop before the cavity wall or the rear cover is opened — The sensor run is not an owner-serviceable path, and the checks stop at the cavity wall.
Before anything is opened
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Built-in ovens rarely have a plug; the breaker is what isolates them. Cavity and door glass hold heat long after the cycle has finished. Do not re-route or hold closed anything on the door circuit; it takes power away at a point the design depends on.
When this stops being an owner job
Call as soon as the code repeats after a power-down. Beyond that the diagnosis needs instruments rather than observation, and reaching the rear of a built-in oven means unseating it from the cabinetry first. Bring the call forward if you smell burning, find scorching near the control area, or the breaker trips as the appliance starts.

What this page does not cover
The reading of F02 given here is the one the shared Maytag oven code set carries, and it applies to the model lines built on that control platform. Earlier generations that reuse these characters for a different condition are outside it. So are wiring colours, connector positions, torque figures and part numbers, all of which vary by family and belong on a family page rather than here. If a page exists for your family or model, go there first — it is the more specific answer — and the code index below lists them.
