The short answer
Supply and usage dominate here: shared sockets and extension leads cause resets and weak performance, while food residue and metal in the cavity cause the arcing events. The turntable is the usual source of noise, and a genuine heating failure is a service call.
What owners report on counter units
- The display resets or the clock keeps flashing — A supply problem. See the controls page for the checks.
- Grinding or scraping that follows the plate — Turntable drive or roller ring, on the noise page.
- Runs and leaves food cold — The not-heating page, and a service outcome.
- Door will not latch, or latches and will not run — Two different faults, both on the door and seal page.
- Nothing at all when plugged in — The will-not-start page, beginning at the socket.
- Sparks or a burnt mark on the cover — Stop and read the electrical-safety page now.
The classes in frequency order
- Supply and installation — First on a counter unit: shared circuits, extension leads and tired sockets produce resets and slow heating.
- Turntable and mechanical wear — Second, and the most common noise source once the vent blower is out of the picture.
- Cavity contamination and user habits — Third: carbonised splatter and metal-trimmed dishes cause most arcing events.
- Door, latch and interlock — Fourth, and driven by slamming rather than by sag.
- Heating — Fifth, and always a service call.
- Controls and keypad — Last, because away from a range plume a panel lasts much longer.

The standing rule
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and in a microwave that charge can kill, so the case is never opened at home. Never run the unit empty, and stop using it if the waveguide cover is scorched or if you see arcing.
What you can and cannot take on
Moving the unit to its own wall socket, giving it clearance, cleaning the cavity and the cover face, washing the plate and roller ring and clearing a lock are all owner work. Anything behind the case is not, and that includes every heating fault and every interlock switch. Disconnect and call, rather than diagnose, if there is arcing, scorching or a burning smell.

A generalized hub
Written across families for counter-standing units; the companion hub covers mounted installations. Where a family-specific or model-specific page exists, it holds the narrower answer and the pages below link onward. Deliberately absent: part numbers, internal component detail, ventilation clearances by model and any procedure involving the case.
