Inverter magnetron
Live display, cold cavity — inverter stage before a quote.

Microwave repair in Sergeli-8: an inverter that will not heat or a new-niche built-in that will not start — we test high voltage before quoting.
On LG and Panasonic in new southern kitchens an inverter magnetron stays cold with a live display more often than a simple diode.
Sergeli-8: a built-in in a new-build niche — we do not pull the trim first; leave counter space.

If the microwave hums but won't heat, or heats weakly, the magnetron is often the cause. The magnetron generates microwaves — without it, the oven is just a box with a timer.
During diagnostics, the technician checks the magnetron, capacitor, diode, and fuse. If the magnetron has failed, we'll suggest a replacement matched to your model. Repair usually takes 1–2 hours when the part is available.
Tell us the model and symptoms — we'll advise on a home visit and prepare for diagnostics.
