The short answer on F1-8
F1-8 means there may be a problem with the oven control, the user interface or keypad, or the wiring between them. Before assuming a failure, rule out a control lock, which also makes keys seem dead; if keys still fail or the code returns, the keypad or control needs testing.

Behaviour that comes with F1-8
- Keys that stopped working one at a time — Wear on the most-used keys, such as start and cancel, shows first.
- No response from any key, with a lock symbol shown — A control lock, not a fault; it is released from the keypad.
- A bubbled, lifted or discoloured panel overlay — Heat or moisture has reached the membrane underneath.
- F1-8 after a key was held down for a long time — The control may flag a key it reads as stuck.
Why F1-8 appears, in likelihood order
- Worn contacts in the keypad membrane — First: the most-pressed keys fail first, and a membrane that has seen heat fails sooner.
- A ribbon tail that has lost contact — Second: heat cycling and vibration ease it out of its socket on the control.
- Moisture or heat damage under the overlay — Third: a bubbled overlay often means the circuit beneath is compromised.
- The oven control's keypad input — Last: the control can fail to read a good keypad, confirmed by testing.
Diagnosing F1-8: the order that saves time
- Check for a control lock — A lock symbol, or keys that all fail at once, often means the lock is on.
- Test each key individually — Shows whether one area or the whole keypad has failed.
- Inspect the overlay — Bubbling or lifting points to the membrane.
- Have the ribbon and control tested — With the console open, a technician checks the connection and the input.
Clearing F1-8 and checking it safely
- Release a control lock — Most controls unlock by holding the lock key, or the key the manual names, for a few seconds.
Tools: owner's manualAbout 2 min
- Test every key — Press each once and note any that stay silent or respond late.
About 3 min
- Reset the control — Breaker off for a minute, back on, and retest the keys.
Tools: breaker panel accessAbout 3 min
- Keep sprays and heat away from the panel — Spray cleaner onto a cloth, and do not rest hot pans against the console.

Safety on this appliance
Safety
Unplug the range or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A keypad that misreads presses can leave the oven running, so if heating starts or stops on its own, switch off the breaker. If you smell gas on a gas range, do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside.
Reset or repair: where the line is
Call if keys stay dead after a lock check and a reset, if the overlay is bubbled or lifting, or if F1-8 returns. The technician tests the keypad and the control separately, since replacing the wrong one leaves the fault in place.

Model coverage and limits
This reading of F1-8 applies to Amana ovens whose control reports the control and keypad circuit with this code, as the table states. Other Amana controls report keypad faults in other formats, and glass touch panels fail differently from membrane keypads; a model-specific page, where one exists, is the better guide. None is listed for F1-8 yet, so start at the Amana oven code index below.
