The short answer
F3 E4 is a code the Maytag table lists without a component: the entry reads only that the location may vary. That is worth knowing rather than guessing around — on this brand the same code number is used across model lines for different circuits, so the meaning depends on the model in front of you. Do the reset, then get the code read against your own model.

|---|---|---|
| F3 E4 | Location may vary. | partly |
| F3 E3 | There may be a problem with the Oven Temperature Sensor, or the associated wiring. | see page |
| F3 E5 | There may be a problem with the Lower Oven Temperature Sensor, the Control, or the associated wiring. | see page |
What you observe
- The code appears with no consistent trigger — Without a named circuit there is no single behaviour to expect.
- Other functions behave normally — Noting what still works is the most useful thing you can record.
- NEAR MISS — a different code with the same first character — Codes that share a prefix are not the same fault; read the table above carefully.
Likeliest causes first
- Whatever circuit your model line assigns to this code — First, and the honest answer: the table declines to name one, so the model number decides what the code covers.
- A latched control state — Second: as with any code, a supply disturbance can leave a control reporting something that has already passed.
- A connection in the circuit the code covers — Last only in ordering, not in likelihood — connections are the usual failure wherever the circuit turns out to be.
Check in this order
- Record the exact code and what you were doing — With no published component, the circumstances are the diagnosis.
- Cut the breaker for a minute and see whether it returns — Free, and it tells you whether anything is actually broken.
- Have the code read against your model number — A technician with the service documentation for your line can name what this one covers.
Owner-safe steps
- Write down the code, the function you selected and what happened — This is the information that turns an unspecified code into a diagnosis.
About 5 min
- Cut the breaker for a minute, then repeat what triggered it — Reproducing it deliberately is far more useful than waiting for it.
About 15 min
- STOP HERE — do not start replacing parts on a guess — A code with no published component is the worst possible basis for buying anything.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. An oven carries a heavy element circuit behind the rear panel, and the cavity stays dangerous long after the heat is off. Leave the door lock and its switch wired exactly as they are.
When to call
Call when the code returns after a reset. Be ready with the model number: for this code it is not a formality but the actual key, because the table itself says the location varies. A technician with the service documentation for your line can turn the code into a named circuit in minutes, and until that happens nobody should be ordering parts.
Neighbouring codes — F3 E3 and F3 E5 appear beside F3 E4 in the table and are recorded against different hardware — different questions with different answers. A shared prefix on this brand is not a shared fault.
What this page does not cover
Generalized information: this reads F3 E4 as the shared Maytag oven table records it, so it covers the model lines using that table and no others. Where a page exists for your family or model line, that one is the more specific answer — start there if your model is named. Not here: wiring colours, connector positions and part numbers, which differ by family.
