The short answer
A door fault on the SMD line is the one microwave problem that is always a safety matter rather than a performance one. These units depend on the door, its frame and its seal surface being intact and correctly aligned, and a unit with a damaged door should be taken out of use rather than run carefully.
What you observe
- The door no longer closes with its usual positive action — On the models listed in the table on this page, the clearest early sign, and it is felt rather than seen: the familiar firm seating is replaced by something vague.
- The appliance refuses to run with the door apparently shut — The door system is not reporting closed, which is the appliance behaving exactly as designed.
- A visible gap along one edge of the closed door — A dropped hinge or a distorted door, and it is a reason to stop using the appliance immediately. The models in the table behave the same way here.
- NEAR MISS: the door is fine and the food stays cold — That is a heating fault and the heating-failure page for this family covers it.
Causes, most likely first
- A worn or damaged door latch assembly — First on the SMD line because the latch takes the whole mechanical load of every door closure, thousands of times, and because its wear shows first as a door that no longer seats positively. That holds across every model this page covers.
- A dropped or loose hinge — Second because it produces a gap along one edge while the door still appears to close, and because it develops gradually enough that owners adjust to it without noticing. That is true of every model this family spans.
- Food residue on the sealing surfaces — The one cause on this list that is owner work: built-up residue around the frame can arc under load, and cleaning it is straightforward and worth doing regularly.
- Impact damage to the door or frame — A dent, a bend or a crack from a knock changes the geometry of the whole assembly, and no amount of careful closing restores it.
- Any damage to the door, frame or sealing surfaces — Treated as terminal for owner purposes: a microwave with a compromised door assembly is taken out of service and seen by a technician, and it is never run in the meantime.
Check in this order, and why
- Close the door and feel for the usual positive action — First on the SMD line because the change is felt long before it is visible, and because it is the earliest warning available. It is the same on all the models in the table on this page.
- Look along the closed door for an even gap all round — Second: a gap at one edge points at a hinge that has dropped, which is a reason to stop using the appliance.
- Inspect the sealing surfaces for damage or scorching — Third, and the check that decides whether the appliance is used again before a technician sees it. This applies to the whole line rather than to one model.
Before you begin
Safety
Unplug the appliance before doing anything beyond cleaning its surfaces. A microwave capacitor can hold a dangerous charge long after the unit is disconnected, so no panel should ever be removed by an owner on this class of appliance.

When to call a technician
Call as soon as the door fails to seat positively, shows a gap along any edge, or carries any visible damage. On the SMD line the door is replaced as an assembly and there is no owner-side adjustment at any skill level. The same is true of each model covered here.
