F8E5 in plain terms
F8E5 means the oven could not execute the function, and there may be a problem with the exhaust air temperature sensor or its associated wiring. That sensor reads the temperature of the air leaving the oven, and without a trusted reading the control stops rather than run without that check; reset once, keep the vents clear, and have the sensor tested if F8E5 returns.

What you see with F8E5
- A function refused with F8E5 — The control will not run it without a trusted exhaust reading.
- Cooking that stops partway — The reading lost once the oven was running.
- F8E5 after heavy, smoky cooking — Residue reaching the sensor in the exhaust stream.
- The code at every start — A sensor or wiring fault present all the time.
Causes of F8E5, ranked
- The exhaust air temperature sensor — First: the documentation names it, and it sits in the hot, greasy air leaving the oven.
- The sensor's wiring or connector — Second: a lead or plug aged by heat, or loosened.
- Residue on the sensor — Third, and not on the documented list: heavy grease or smoke deposits affecting its reading.
- A one-off fault — Last: a code that clears with a reset and does not return.
What to check first for F8E5
- Reset with the power off — A free first check for a passing fault.
- Check the vents are clear — Nothing should cover the vent the exhaust air leaves through.
- Note which function failed, and when — At the start or partway helps separate the sensor from its wiring.
- Have the sensor and wiring tested — A technician measures the sensor against the tech sheet chart.
What an owner can safely do about F8E5
- Reset the oven — Switch off the breaker for a minute, then on, and try the function once.
Tools: breaker panel accessAbout 3 min
- Uncover the vents — Remove anything sitting over or against the oven's vents.
About 2 min
- Wipe the vent opening, power off — With the oven cold, wipe grease from around the vent opening with a barely damp cloth.
Tools: soft clothAbout 5 min
- Record the pattern — Note the function, whether it failed at once or partway, and what you were cooking.
Tools: pen and paperAbout 2 min
Safety before you start
Safety
Switch off the breaker before removing any panel; a capacitor can hold a charge after the power is off. Let the oven cool before wiping near the vent, which runs hot, and never cover it with foil or cookware. 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.
When to book a service call for F8E5
Call if F8E5 returns after a reset, if functions keep refusing to start, or if the code appears at every start. The technician tests the sensor against the tech sheet chart and checks its wiring; the sensor is a modest part, usually replaced in one visit.

What this reading does not cover
This reading of F8E5 applies to Amana ovens whose control reports a function that could not be carried out, naming the exhaust air temperature sensor or its wiring, as the table states. Sensor location and vent layout vary by model, and a model-specific page, where one exists, is the better guide. None is listed for F8E5 yet; start at the Amana oven code index below.
