For hum without heat we measure the HV transformer secondary on Whirlpool or Bosch.
For sparking we replace the waveguide mica on Candy or Beko.
If time does not advance we test the relay and timer on Midea or Electrolux.
Topic 1 / 3
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.
