The short answer for EM models
On an Avanti EM microwave, the door carries three interlock switches behind its latch assembly, and they are wired so that a door which is not properly shut cannot allow the oven to run. Most door complaints on this line are a latch hook or a hinge that has worn, and the safe response to all of them is the same.
What the owner sees
- A gap visible along one edge with the door shut — The door is not square in the frame and the seal face is not meeting the cabinet evenly.
- A rattle from the door while the oven runs — A loose latch assembly or a broken hook rattling in its housing.
- The door has to be pressed or lifted before the oven will run — The latch hooks are no longer aligning with their switches.
- The latch hooks look bent or worn — The plastic hooks are consumable and they are what operate the switches.
- NEAR MISS — sparks from inside the cavity rather than the frame — That is usually metal in the oven or damaged cavity paint, and it is its own fault.
The ranking for this family
- Latch hooks worn or broken — Ranked first because they are the part that operates the interlocks and the part that takes every closing of the door.
- Seal face or choke channel damaged — The most serious item on this list and the one that ends the useful life of the appliance.
- Hinge worn or dropped — The door no longer sits square, so the latch and the seal face both meet the cabinet wrongly.
- Latch assembly loose in the door — Screws backed out, which produces a rattle and a door that sometimes works.
The order that saves the most time
- The order, and why it is this one — This order exists because the cheap causes are also the likely ones: zero of the four named above can be settled on EM models before a tool comes out.
- Open and close the door slowly and watch the latch hooks — Bent, worn or broken hooks are visible from outside and are the commonest cause here.
- Stop using the oven before testing anything — Every fault on this page involves the part that contains the energy, and that changes the order of everything else.
- Look at the seal channel round the door for residue or damage — Residue is cleanable. Damage is not, and it takes the oven out of service.
Why the case stays on
Safety
Switch the oven off at the socket and unplug it. On a microwave the high-voltage section holds a charge in its capacitor after the power is off, and that charge is lethal. There is no owner-serviceable part inside the case and no safe way to establish that the capacitor has discharged without the right tool.

When to call a technician
Call for anything that is not cleaning. The high-voltage capacitor inside can hold a lethal charge after the oven is unplugged, so there is no owner repair on this appliance beyond the cavity, the turntable and the door seal face.
