The short answer first
On a Meneghetti Fulgor microwave, an oven that will not begin is most often a door that is not satisfying its interlocks rather than a membrane touchpad that no longer makes contact. The door and its sealing surfaces, and the installation around them, come first: a panelled built-in fails at its interfaces long before it fails at its components. Every check here is outside the cabinet, and the cabinet must never be opened.
What you observe
- Completely dead — no display, no light — A dead display is a supply question before anything else.
- The turntable turns but nothing runs — A partial response means the oven is part way through accepting a programme.
- The door has to be pressed to make it latch — A latch that needs help is a latch that has worn.
- NEAR MISS — it starts and sparks inside — Arcing is an electrical-safety matter and it has its own page.
What goes wrong here, in order
- A door that is not satisfying its interlocks — Three interlock switches must agree before the oven will run. A worn latch, a dropped door or crumbs on the strike plate leaves the panel lit and the oven refusing to start, with no fault displayed. It leads because this door is opened many times a day and the latch is the part that wears out first. It is installed by a kitchen fitter into an aperture with a trim kit, and the trim kit decides the airflow.
- Protection refusing to start until the oven has cooled — An oven with blocked vents runs hot inside and a thermal device stops it restarting until it has cooled. It looks dead and it is protecting itself. It sits here because giving it space and an hour is a free test.
- A membrane touchpad that no longer makes contact — A touchpad wears from underneath. Some buttons respond and others do not, and the oven appears to ignore commands at random rather than consistently. It is last because every button responds reliably.
Check in this order, and why
- Close the door and watch how positively it latches — A door that needs pressing is a latch that has worn. First, because it is the likeliest to end the job.
- Leave it an hour with the vents clear and retry — An oven that starts when cool was protecting itself. Second, once that is clean.
- Press every button in turn and note which respond — A pattern of dead buttons is a worn membrane. Third, and by now the answer is usually in hand.
The steps, with tools and times
- Clean the door edge, the latch and the strike plate — A damp cloth only. If the latch is broken or the door is bent, stop using the oven.
Tools: clothAbout 10 min
- Move the oven clear of walls and cupboards and let it cool — Then retry with the vents unobstructed.
About 20 min
- Note which buttons fail, then stop — A touchpad is a cabinet-open repair and that cabinet must stay shut.
About 10 min
- STOP — do not open the outer cabinet under any circumstances — The capacitor inside holds a dangerous charge long after the oven is unplugged.
The part that is not optional
Safety
Never open a microwave's outer cabinet. The high-voltage capacitor inside holds a dangerous charge long after the oven is unplugged. Never defeat or tape a door interlock to make an oven run, and never run the oven empty.
Where the owner fix ends
Call, or replace, once the socket, the display, the door and the vents have all been checked and the oven still does nothing. Everything past that is inside a cabinet that must stay closed, and on an oven of this class replacement usually wins on cost. On this brand parts come through the importer and are neither cheap nor quick, which makes the free checks worth doing first.

What this page does not cover
This page is written for the appliance class, not for one Meneghetti Fulgor model line. Where a family- or model-specific page exists it is the better answer and it is linked below — go there first if your model is named. Not here: interlock arrangements, touchpad references, fuse ratings, or part numbers.
