The short answer
A Maytag oven showing 4d52 has flagged the door latch and switch. The exact documented wording is in the table; the order of the checks below it is the part worth reading twice. Leave the function that needs the door locked alone until the latch works.
The documented code and its meaning
Reference| Code | Meaning |
|---|---|
| 4d52 | There may be a problem with the Oven Door Latch Assembly, the Door Switch, or the associated wiring. |
What you actually observe
- The latch motor buzzes or clicks repeatedly — A motor that keeps trying is a motor that is not reaching its seat.
- The oven refuses to start with the door apparently shut — The control is being told the door is open.
- The door has to be pushed or lifted to close properly — That is an alignment symptom and it is the cheapest cause in this family.
- NEAR MISS — the door closes and locks normally and the code still shows — Then the switch is reporting incorrectly and the mechanism is fine.
Causes, most likely first on this oven
- A latch motor or cam not completing its travel — The switch closes only at the very end of the stroke, so a latch that stops just short reports as one that never arrived at all.
- A door switch that no longer changes state — These contacts stick closed as readily as they fail open, which lets the control believe a door is shut when it is standing open.
- The door and the frame out of alignment — Hinges settle and strikes wander; the latch then cannot reach its seat and nothing electrical is at fault at all.
- The wiring between the latch assembly and the control — The harness runs across the hinge line on many designs, which is the one place in the appliance that flexes every day.
Check in this order, and why
- Work the door slowly and listen to the latch — A latch that hesitates, buzzes or stops short answers the question before a single screw is turned.
- Check that the door sits square against the frame all the way round — A consistent gap right around the door clears the mechanical half of the family for free.
- Look for anything trapped in the latch path — Foil, a rack, packaging or a stray screw is a routine finding here.
- Leave the latch assembly itself until the alignment is confirmed — A new latch fitted to a misaligned door produces this same code before the technician has left.
What an owner can safely check
- Take the power off, then work the door by hand and watch the latch — You are looking for a latch that reaches its seat smoothly, not for anything electrical.
Tools: flashlightAbout 8 min
- Clear anything trapped around the latch or the strike plate — Hardened spill on the strike plate takes away just enough travel to cause this.
Tools: soft clothAbout 10 min
- Power the unit back up and try one short cycle with the door closed firmly — If a deliberate firm close clears it, the fault is alignment and not electronics.

Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A built-in oven is normally hard-wired, so the breaker is the isolation point rather than a plug. The cavity and the door glass stay hot for a long time after a bake cycle ends. Nothing on the door circuit should be re-routed or held closed. It interrupts power by design.
When this stops being an owner job
Call if the latch does not complete its travel, or the code stays after the door path is clear. After that the next move is behind a panel, and the oven generally has to come out of its housing before the connections behind it can be seen. Bring the call forward if you smell burning, find scorching near the control area, or the breaker trips as the appliance starts.

What this page does not cover
The reading of 4d52 given here is the one the shared Maytag oven code set carries, and it applies to the model lines built on that control platform. Earlier generations that reuse these characters for a different condition are outside it. So are wiring colours, connector positions, torque figures and part numbers, all of which vary by family and belong on a family page rather than here. If a page exists for your family or model, go there first — it is the more specific answer — and the code index below lists them.
