The short answer
F9-3 is a door-lock fault: the table names the Oven Door Latch and its switches, meaning the control asked the door to lock or unlock and never got the confirmation back. The oven will usually refuse a clean cycle, and it may hold the door shut until the fault clears. Do not force it — the motor that drove the catch there is what has to bring it back.

What you observe
- The door stays locked after the cycle ends — The latch ran, but no switch told the control it arrived.
- The latch motor hunts back and forth — That sound is a control not seeing the switch it expects.
- NEAR MISS — the door will not close flush — A door that will not shut is a hinge or gasket job and makes no code.
Likeliest causes first
- A mis-set or worn door switch — First: the switch must be struck exactly, and a latch that has shifted misses it by a hair while looking perfectly normal.
- The latch motor or the Oven Door Latch — Second: it is mechanical, it runs hot every clean cycle, and its gearing wears — often failing mid-travel, which is why the door stays shut.
- The harness to the latch, or the control input — Last: the loom crosses the top of the cavity and is heat-aged, but a broken wire there is rarer than a switch out of adjustment.
Check in this order
- Let the cavity cool, then cut power for a minute — A hot oven will not unlock by design, and many locked doors are simply hot ones.
- Watch and listen through one lock attempt — Whether the motor runs, stalls or does nothing separates mechanical from electrical.
- Check the door for square and a clean strike — A sagging door presents the catch at the wrong height, which is a hinge repair.
Owner-safe steps
- Wait for the cavity to go cold with the breaker off — Most locked-door complaints end here: the lock is held while the cavity is above a safe temperature.
About 90 min
- Restore power and cancel any clean cycle from the panel — A cancelled clean releases the lock on its own once temperature allows.
About 5 min
- STOP HERE — the latch is reached from above the cavity — Top panel off on a built-in, or the appliance drawn out on a range, breaker off.
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 if the door is still locked with the cavity cold and the appliance power-cycled, or if the code returns whenever a clean is selected. The Oven Door Latch is a stocked part and the job is bounded, but reaching it usually means the oven coming out of its housing. Never prise a locked door: the catch is steel, and a bent frame costs far more than the latch.
Neighbouring codes — F9-2 and F9Q sit beside F9-3 and name overlapping hardware, so most checks here carry across. Read the two meanings side by side: where they differ in the part named, the order of the checks changes with them.
What this page does not cover
This page is written for the Maytag oven class rather than for one model line, and F9-3 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.
