The short answer
The reading F1-1 on this oven names 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 |
|---|---|
| F1-1 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you actually observe
- The oven takes far longer than it used to — A control that cannot trust its reading waits rather than stops.
- The code appears immediately on a cold start — A cold fault points at the wiring and the plug rather than at the sensor element.
- The appliance overshoots the setting and then corrects sharply — Wandering readings produce wandering control.
- 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 — These elements wander rather than break, so results go off well before the control refuses the reading outright.
- Corrosion or slackness at the sensor plug — That plug lives in the hottest, dampest part of the run, which is why it — and not the element — is so often what has failed.
- 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 — A cold fault points at the wiring and the plug; a hot one points at the sensor itself.
- Get the sensor resistance read at the plug — One resistance reading at the plug separates element, wiring and board in a single measurement.
- 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 sensor fault sometimes clears; one that returns at once is a live fault worth a call.
About 3 min
- Note the temperature behaviour you have seen recently — 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 disturbed — The sensor run is not an owner-serviceable path, and the checks stop at the cavity wall.
Before anything is opened
Safety
Power off before panels 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 interlocking switches wired as they came. They exist to remove power at the moment it has to go.
When this stops being an owner job
A technician is the right next step as soon as the code repeats after a power-down. Past there the work needs a meter or a panel removed, and a wall oven has to be unseated from its cabinet before the rear connections are reachable. A burning smell, scorching around the controls or a breaker tripping at start-up all change the answer to now, whatever else this page says.

What this page does not cover
What is written here about F1-1 comes from the code set shared across Maytag oven model lines on one control platform. It does not extend to earlier control generations that happen to display the same characters for a different condition. Wiring colours, pin assignments, torque values and part numbers are all left out on purpose: they are family-specific and belong on the page for that family. Where such a page exists, it is the more specific answer and takes precedence over this one; the linked index is where to find it.
