In one paragraph
In plain terms, 9d22 means the oven door latch assembly or the door switch and the wiring between them and the control disagree about whether the door is where it should be. The cycle is held rather than the machine being unsafe: the control will not commit without a door it can verify.
The code and what the manufacturer documents for it
Reference| Code | Documented meaning |
|---|---|
| 9d22 | There may be a problem with the Oven Door Latch Assembly, the Door Switch, or the associated wiring. |
The behaviour that comes with this code
- The door will not lock, or will not release — Both are the same fault: the control cannot confirm the position, so it will not move on.
- The code arrives at the end of a cycle rather than the start — A lock that releases badly reports the same disagreement as one that engages badly.
- NEAR MISS - the door is locked and the display is dark — A dark display with a locked door is a power fault, and the release for it is a different procedure.
The ranked causes behind this reading
- Something in the way of the door or the strike — Ranked first because it needs no tools: a packed load, a rack proud of its rail or a bent strike stops the door short of the position the switch reports.
- The switch inside the latch not changing state — Second: the contact is the part that wears, and it fails to make long before the motor stops turning.
Where to start, and what follows
- Open the door and look along the strike and the seal — Free, and it finds the obstruction that causes most of these.
- Power the machine down and let the lock reset itself — A lock stopped mid-travel homes itself on the next power-up.
The owner-safe sequence
- Check the hinges and the seal for an obvious drop — A door sitting low on its hinges misses the strike by a few millimetres, which is enough.
About 10 min
- Test the door seal with a strip of paper at each corner — Even resistance all round means the door is meeting the seal.
About 10 min
- STOP HERE if the lock assembly has to come out — Leave the door switch and its wiring exactly as the manufacturer fitted them: they are what keeps the machine from running with the door open.
What to do before any panel comes off
Safety
Before any panel comes off: unplug the appliance or switch off its breaker, because a capacitor can hold a charge after the power is off. Nothing on this page asks you to work on a live circuit, and nothing on it asks you to alter a switch or an interlock - those are what keep the appliance safe when it is running.
The point at which you call
The line is straightforward. Call when the door still will not lock with a clear opening, or when the code returns after a power-down: a lock motor and its switch are a single service assembly on most of these machines. Separately and more urgently: call before using it if the door can be opened while a cycle is running.

How far this page applies
Scope, stated plainly: the model lines that lock the door under control rather than by hand, and this code only. Model-specific detail - the pinouts, the resistance values, the part numbers - is not on this page, because those differ between families and a wrong figure here would be worse than no figure. The index linked below lists the pages for specific families and models where they exist, and a page about your model outranks this one.
