The short answer on F3-1
F3-1 means there may be a problem with the oven temperature sensor, the control or the wiring between them. If it appeared right after an outage, a storm or flickering power, start with a full power-down, because a disturbance can upset the control's reading of a healthy sensor; if F3-1 persists, test the sensor first.

Behaviour that comes with F3-1
- F3-1 when power returned after an outage — The timing points to the supply event.
- Other appliances reset or misbehaving too — The same disturbance reached them.
- The code cleared by a long power-down — A control that was confused rather than damaged.
- F3-1 that stays after several resets — Something in the circuit was damaged, or the sensor has genuinely failed.
Why F3-1 appears, in likelihood order
- A control upset by the disturbance — First when F3-1 followed an outage or surge and a long power-down clears it.
- The oven temperature sensor — First otherwise, and still the most common lasting cause.
- Damage to the control's sensor input — Third: a surge can damage the input while the rest of the control works.
- Wiring or a connector — Last: rarely affected by a supply event, but checked as usual.
Diagnosing F3-1: the order that saves time
- Do a full power-down — Breaker off for several minutes lets the control restart cleanly.
- Test the sensor if the code persists — A good reading with the power off points to the control's input.
- Check other appliances — Several affected devices point to the supply event.
- Have the control input tested — A technician confirms damage before replacing the control.
Clearing F3-1 and checking it safely
- Power down for several minutes — Breaker off, wait, then on, once the supply has been steady for a while.
Tools: breaker panel accessAbout 5 min
- Run a short bake — Watch whether F3-1 returns.
About 10 min
- Measure the sensor if it does — Power off: unplug the sensor and compare its resistance with the tech sheet chart.
Tools: multimeter, screwdriverAbout 15 min
- Note the supply event — Record when it happened and what else was affected.

Safety on this appliance
Safety
Unplug the range or switch off its breaker before removing the sensor or any panel; a capacitor can hold a charge after the power is off. During a storm or on an unstable supply, leave the oven off rather than restarting it repeatedly. On a gas range, if you smell gas, do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside. Once power returns, wait until the supply has been steady for a while before switching the oven back on.
Reset or repair: where the line is
Call if F3-1 survives a long power-down and the sensor tests good, or if several appliances were affected and the oven still shows the code. A damaged control input means the control is replaced, and an electrician may need to check the supply so the new part is protected. Tell the technician about the outage or surge when you book, because it changes which part they test first and may matter for an insurance claim.

Model coverage and limits
This reading of F3-1 applies to Amana ovens whose control reports the oven temperature sensor circuit with this code, as the table states. Other Amana controls report the same circuit in other formats, and a model-specific page, where one exists, is the better guide. None is listed for F3-1 yet; the Amana oven code index below is the starting point.
