The short answer
F3 is the control reporting that it could not carry out what it was asked to do, with the Oven Control and its wiring named. Unlike a sensing code, this one is about the board that switches things rather than the thing being switched. Power the appliance down and see whether it returns: a code that stands after a reset is a service call.
Code table
Reference| code | meaning | owner-checkable |
|---|---|---|
| F3 | There may be a problem with the Oven Control, or the associated wiring. | no |
| F2Q1 | There may be a problem with the User Interface (Touchpad) or the associated wiring. | see page |
| F3-1 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. | see page |
What you observe
- A function starts, then aborts — The selection is accepted and then dropped mid-step.
- Relays click repeatedly, or not at all — Either extreme points at the switching stage, not the load.
- NEAR MISS — the panel is dead and unlit — A blank panel is a supply question and belongs on another page.
Likeliest causes first
- A genuine fault on the Oven Control — First, because this code names the board rather than something it reads: relay contacts and their drivers carry load, and load is what wears them.
- The harness between the boards — Second: the control board talks to the interface and the relay stage through connectors, and a dirty one imitates a board fault exactly.
- A supply disturbance that latched a state — Last, but it is why the power cycle comes first — a brownout mid-cycle leaves a control reporting a fault it no longer has.
Check in this order
- Cut the breaker, then retry the same function — Free, and it splits the three causes at once: a code that stays away was a state.
- Note exactly which function fails — Bake, broil, clean and convection use different outputs of the control board.
- Leave the board itself to a meter — Boards are judged by output with the load on and off; a scorched-looking board is not always the failed one.
Owner-safe steps
- Record the code, then cut power at the breaker for a minute — The one diagnostic an owner can run on a control fault, and its result is genuinely informative.
About 5 min
- Try each cooking function once afterwards — One failing function means one output stage; all of them means the shared control.
About 20 min
- STOP HERE — board work is behind the panel on live-adjacent circuits — Nothing beyond the reset and that observation is an owner job here.
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 as soon as the code survives a power cycle. A control board is among the dearest parts in the appliance, which is exactly why nobody should fit one on the strength of a code: the job is to prove the board rather than the harness or the load before it is ordered. Ask for the failed output to be named — a board changed without that is a board changed on a guess.
Neighbouring codes — F2Q1 and F3-1 appear beside F3 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
This page is written for the Maytag oven class rather than for one model line, and F3 is read exactly as the shared table records it. If your family or model has its own page, that page is the more specific answer and it is linked below — go there first when your model is named.
