The short answer
Two families dominate: noise and airflow complaints from the vent side, and control complaints from a keypad that lives in the steam of the range. Heating failures are less frequent but always end in a service call, because everything that produces heat is behind a case nobody should open.
The problems that actually turn up
- Roaring, rattling or grinding noises — Usually the blower, the mounting or the turntable. The noise page ranks them.
- Keys dead in a zone, or a display that is half lit — A membrane keypad in a steam plume. See the controls page.
- Runs perfectly and leaves the food cold — The high-voltage side, and a service call. See the not-heating page.
- Refuses to start, or stops partway through — Door chain and interlocks, on the door and seal page.
- Dark and silent — Start with the plug in the cabinet above, on the will-not-start page.
- Sparks, scorch marks or a burning smell — Stop and disconnect. The electrical-safety page covers what to do.
Problem classes in the order we meet them
- Ventilation and noise — The largest class on a mounted unit, because the blower handles grease-laden air continuously.
- Controls and keypad — Second, driven by heat and steam rising from the cooktop into the panel.
- Door, latch and interlock — Third: heavy doors opened one-handed drop at the hinge over years.
- Heating — Fourth by frequency and first by cost, since every cause is behind the case.
- Supply and power — Fifth, and dominated by the hidden socket in the cabinet above.
- Electrical hazard events — Last by frequency and first by urgency; arcing and burning smells stop the appliance immediately.
Where the complaints sit on a mounted unit
General guidance| Problem class | Rank here | Owner checks available? |
|---|---|---|
| Ventilation and noise | First | Yes, filters and turntable |
| Controls and keypad | Second | Locks and resets only |
| Door and interlock | Third | Cleaning only |
| Heating | Fourth | Water test only |
| Supply and power | Fifth | Yes, socket and breaker |
| Hazard events | Last | Disconnect and call |

One rule above all others
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 stored energy is lethal, so the case is never opened at home for any fault on this list. Leave the door interlock system exactly as built, and stop using the appliance if anything inside it has scorched.
Which of these you can take on
Cleaning grease filters, washing the turntable and roller ring, checking mounting screws, reseating the plug above the unit, clearing a lock and closing the door properly are all owner work. Everything else here is a service call, because it lives behind the case. Two symptoms skip the diagnosis entirely and go straight to a call: arcing inside the cavity and any burning smell.

The generalized page
This one is written across families and model lines for mounted units, so it names and routes rather than instructing. The companion hub covers counter-standing units, and where a family-specific or model-specific page exists it is the more precise answer. Not here: part numbers, internal procedures, ventilation specifications and lock sequences by panel generation.
