The short answer
On a Maytag oven, F1 points at the temperature sensor circuit. What the manufacturer documents is in the table; what to check first is in the ranking under it. It is usable if it still holds temperature; stop if it overshoots or cuts out.
The documented code and its meaning
Reference| Code | Meaning |
|---|---|
| F1 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you actually observe
- The code appears once the unit is hot, not at the start — That timing is the most useful thing you can tell a technician.
- Pre-heat or warm-up takes far longer than it once did — A control that distrusts its reading waits rather than stops.
- Temperatures run high or low against the setting — A drifting sensor shows up in the cooking or drying result weeks before the code does.
- 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 — These elements wander rather than break, so results go off well before the control refuses the reading outright.
- A corroded or loose connector at the sensor plug — The plug sits in the hottest and dampest part of the run, which is why it, and not the sensor, is so often the fault.
- 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 — Whether it faults from cold or only when hot decides which half of the circuit to look at first.
- Ask a technician to read the sensor resistance at room temperature — One measurement at the plug separates the sensor from the wiring and the board in a single step.
- 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 — A stored sensor fault sometimes clears; one that returns at once is a live fault worth a call.
About 3 min
- Set down the temperature behaviour of recent weeks — 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 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. 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. 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
Book the visit as soon as the code repeats after a power-down. At that point the next step is a meter or a panel off, and a wall oven has to be unseated from its cabinet before the rear connections are reachable. Whatever the timing above, a burning smell, visible scorching or a tripping breaker means the appliance goes off at the breaker and the call goes in today.

What this page does not cover
This is the platform-level reading of F1: it holds for the Maytag oven families that share that control generation. It stops short of older platforms that display the same characters for a different condition, and it carries no family-specific detail at all — no wiring colours, no pin numbers, no torque figures, no part numbers. Those belong on the page for the family concerned. Where such a page exists it outranks this one, and the code index below is where it is listed.
