The short answer
F01 on a Maytag oven is the control reporting a fault in the temperature sensor circuit. Read the table for the documented wording, then work down the ranked causes rather than across them. Keep using it only while the results are acceptable.
The documented code and its meaning
Reference| Code | Meaning |
|---|---|
| F01 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you actually observe
- 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.
- The oven takes far longer than it used to — A control that cannot trust its reading waits rather than stops.
- 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 sensor element itself drifting out of range or going open — A resistance sensor fails gradually, so the appliance often runs badly for weeks before the control finally rejects the reading.
- Corrosion or slackness 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.
- Chafed sensor wiring where it passes through the cavity wall — Insulation gives way at the grommet where the loom passes the cavity wall, and a conductor touching metal there reads to the control as a short.
- The board input that reads the sensor — Last, and genuinely uncommon: the input stage fails far less often than the sensor and its wiring.
Check in this order, and why
- Note whether the fault appears cold or only once the unit is hot — Cold faults and hot faults come from different halves of this circuit, so the timing is the first thing to establish.
- Get the sensor resistance read at the plug — One measurement at the plug separates the sensor from the wiring and the board in a single step.
- Have the plug at the sensor examined for corrosion and heat damage — Heat damage or green on the pins is cheap to find and cheap to fix, and it is found often.
- Keep the board as the last suspect — Everything else in the chain is cheaper and more likely, so the board waits until last.
What an owner can safely check
- Drop the breaker for a minute and bring it back — A stored fault sometimes goes; one that reappears at once is live and worth the call.
About 3 min
- Note the temperature behaviour you have seen recently — What the appliance has been doing for the past few weeks is the history worth writing down.
Tools: pen and paperAbout 5 min
- Stop before the cavity wall or the rear cover is disturbed — The sensor run is not an owner-serviceable path, and this is where the checks end.
Before anything is opened
Safety
Nothing comes off until the power is off. Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Isolation on a built-in oven means the breaker, not a cord. Give the cavity and the inner door glass real time to cool before working anywhere near them. Leave the door switch and the latch wiring exactly as the factory set them: they cut power where the design intends, and that is not a wire to move.
When this stops being an owner job
A technician is the right next step as soon as the code repeats after a power-down. Everything past that point needs the panels off, and the oven generally has to come out of its housing before the connections behind it can be seen. Call sooner than that if you smell burning, see scorching around the control area, or the appliance trips the breaker when it starts — any one of those is a stop-now signal rather than a wait-and-see one.

What this page does not cover
What is written here about F01 comes from the code set shared across Maytag oven model lines on one control platform. Older control generations that reuse the same characters are not covered, and neither is anything family-specific: wiring colours, connector pin numbers, torque figures and part numbers all change from family to family and are deliberately absent. A family or model page, where one exists, is the more specific answer and should be read in preference to this one — the linked code index collects them.
