The short answer
F1-3 on a Maytag oven is the control reporting a fault in the temperature sensor circuit. The code table records the documented meaning, and the causes below it are ordered by how often each one is the answer. Keep using it only while the results are acceptable.
The documented code and its meaning
Reference| Code | Meaning |
|---|---|
| F1-3 | 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 once the unit is hot, not at the start — That timing is the most useful thing you can tell a technician.
- Results are uneven from one use to the next — An intermittent reading gives an intermittent result.
- 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 — The grommet at the wall is where the covering wears, and bare copper against steel presents to the control as a short.
- The 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
- 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 — A single resistance figure at the plug tells element, wiring and board apart at once.
- 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 — This run is not owner-serviceable, so the checks finish at the cavity wall.
Before anything is opened
Safety
Before any panel comes off, unplug the appliance or switch off its breaker: 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
Arrange a visit as soon as the code repeats after a power-down. From there on it is a meter on a de-energised circuit, 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
Treat this as the family-agnostic reading of F1-3 for Maytag oven models on the common 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.
