Mica and magnetron
In C-1 we cover burnt mica first; the magnetron is tested only after the new sheet if filament heat is already gone.

Microwave repair in C-1: not heating, sparking at the mica, or a dead display — the technician assesses the magnetron and high-voltage stage.
On Whirlpool and BBK we replace burnt mica first, then test magnetron filament heat.
In C-1 panel kitchens leave the counter clear — the cover comes off on site.

Turntable spins, food stays cold: diode and capacitor before the transformer — magnetron only after the quote.
A dark Samsung or BBK screen: board power first, then the ribbon, then the keys.

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.
