What this family is
TM is a family key rather than a model: it groups Bertazzoni microwaves sharing a cabinet, door and control arrangement. What owners report most is no heat with everything else working, and a machine that lights up and will not begin.
Problem classes on this family
- Sparking, burning smells or breaker trips — On these models the arc site is the evidence: foil or metal in the cavity is a usage problem, a scorched waveguide cover is a repeat-arcing fault, and damage to the cavity finish or seal face means the oven stops being used.

- It runs but does not heat — On these models the display, light, fan and turntable all keep working while food stays cold, which narrows the fault to the high-voltage section almost immediately.

- It will not start — Ask first whether the display is alive. Covered in full on: Bertazzoni TM Microwave Dead: What Changes on This Family. — Slug: bertazzoni-bertazzoni-microwave-tm-microwave-wont-start-2
- Door, latch or seal problems — A door that needs a press to make the oven run is the early sign. Covered in full on: Bertazzoni Microwave Door Will Not Close or Seal: What to Do. — Slug: bertazzoni-microwave-door-seal-2
The problem classes in order
- It runs but does not heat — It leads on this family because everything visible from the front is driven from the low-voltage side, so a normal-looking cycle with no heat has already eliminated most of the machine. This ordering is by how the faults usually show up rather than by a counted share: no measured frequency exists for this family, and a frequency without a denominator is not a claim worth making.
- It will not start — It ranks here because door and latch faults are the most common reason one of these refuses to begin, and because both halves of the fault are identified without opening anything.
- Door, latch or seal problems — It belongs high on any microwave family page because the door is part of the containment system rather than a lid, so a door fault is a safety matter and not an inconvenience.
- Sparking, burning smells or breaker trips — It is last in order and first in urgency: least common of them, and the one where the correct response is to unplug the oven rather than to investigate further.
Which models this profile covers — The rating plate carries the model number this key groups; read it before ordering any part.

What an owner can fix on these models
The owner list here is deliberately short: settings, the water test, a look at the door and latch, clear vents and a reset at the socket. The cover never comes off — the capacitor behind it can hold a lethal charge long after the plug is out.
