The answer, before the detail
A Black+Decker EG microwave with a door problem gets checked visually and no further. The hooks, the hinge and the seal surfaces are all on the outside and are all you may touch; the interlocks behind them are not adjustable, not repairable and not to be bypassed. If the oven has ever run with the door open, stop using it now and unplug it. On the EG models the check that decides the order below is which build you have: a touch panel rather than a dial, or not.
What the owner actually sees
- The door needs a push or a slam to latch — Worn hooks or a hinge that has dropped — and a door that needs force is a door on its way to not latching at all.
- The door sits low or crooked in its opening — Look along the seal line in good light.
- It runs for a moment after the door opens — Nothing else on this page matters until that is dealt with.
- Nothing works after the door took a bump — It still needs a technician rather than a nudge.
- A scorch mark or pitting around the door edge — Stop using it. Arcing at the door edge is damage to the part that does the containing.
- NEAR MISS — the door is simply dirty — Unplug it, wipe the surfaces with a damp cloth, and check again.
Most likely first on this family
- An interlock switch has failed — Mid-list by frequency and top of the list by seriousness: a failed interlock either kills the oven outright or lets it run when it should not. Either way: unplug it and stop using it.
- The hinge has dropped or the door is bent — It ranks high because a sagging door loads the hooks and turns one fault into two.
- The seal surfaces are soiled or coated — It is placed here because it is the one cause an owner can put right, and it costs a damp cloth and two minutes.
- Physical damage to the door panel or the seal line — Last, because it is the least common and because it ends the discussion rather than continuing it — a damaged door is not a repair to attempt.
The order that finds it fastest
- First, rule out the two stop-now conditions — Either of those means unplug it and stop using it; nothing further on this page applies.
- Unplug it and clean the door and frame surfaces — Baked-on splashes hold a door open a fraction and are the one cause you can fix outright.
- Inspect the hooks and the catch visually — Rounded, cracked or chipped hooks explain a door that needs a push.
- Sight along the gap with the door closed — An even gap all round is right; a wedge-shaped one is a hinge that has dropped.
Before you open anything
Safety
Never open the cabinet of a microwave oven. The high-voltage capacitor inside can hold a lethal charge long after the machine is unplugged, and nothing behind that cover is an owner part on any model. Unplug the oven before cleaning anything, leave every door interlock exactly as it is, and do not run the oven empty.
Where the owner job ends
The condition is whether a damp cloth fixes it. If the door latches properly once the seal surfaces are clean, nothing else needs doing. If it still needs force, sits crooked, or the oven has run with the door open, unplug it and book it: the cabinet is never opened by an owner, so there is no next step you can take yourself.
