What F04 means
F04 means there may be a problem with the electronic oven control or its associated wiring. The heaters draw heavy current through connections at the control, and a terminal that has worked loose or overheated is a frequent culprit; stop using the oven if you smell burning from the console or if F04 returns after a reset.

What the oven does alongside F04
- F04 together with patchy heating — A heater that works one cycle and not the next, as a hot terminal makes and breaks contact.
- A burnt or hot-plastic smell from the console — The smell of an overheating terminal near the control.
- The code appears after the oven has been heating for a while — Terminals heat up under load, so faults surface mid-cycle.
- Discoloration visible through the console vents — Browning around the control is a late but clear sign.
What triggers F04, most likely first
- The electronic oven control — First, as the documentation lists it, and often damaged by a hot terminal beside it.
- An overheated or loose heater terminal at the control — Second, and closely tied to the first: the cause the control fault usually starts from.
- A harness plug that has backed off — Third: low-current plugs on the board can work loose with heat cycling.
- Wiring damaged elsewhere in the console — Last: heat and age harden insulation near the board.
Check order for F04, and why
- Note whether F04 comes with heating problems or smells — Points straight at the high-current terminals.
- Reset at the breaker — A clean restart separates a glitch from a lasting fault.
- Have the console opened and the terminals inspected — A technician looks for browned or loose terminals, power off.
- Test the control — Only after any damaged terminals are dealt with.
Reset and owner-safe checks
- Reset the control — Breaker off for a minute, back on, and watch the display settle.
Tools: breaker panel accessAbout 3 min
- Use your nose, not your hands — With the oven running a short bake, notice any burning smell at the console; switch off at once if there is one.
About 10 min
- Switch off and leave it off if it smells — A hot terminal gets worse with every cycle; breaker off until it is inspected.
Tools: breaker panel accessAbout 1 min
- Record which heater fails — If bake works but broil does not, or the reverse, note it for the technician.
Tools: pen and paperAbout 2 min

Safety
A terminal that smells of burning is an electrical hazard, not just a fault: switch off the breaker and do not use the oven until it is inspected. Unplug the range or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. 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 F04 needs a technician
Call promptly if F04 comes with a burning smell, discoloration or patchy heating, or returns after a reset. Fixing a burnt terminal usually means replacing the connector and often the control it has damaged, and fitting a new control onto a burnt connector damages the new one.

Which models this reading covers
This reading of F04 applies to Amana ovens whose control reports a fault in the electronic oven control or its wiring, as the table states. Other Amana controls report control faults in other formats, and where a model-specific page exists, it is the better answer. None is listed for F04 yet, so the Amana oven code index below is the starting point.
