Repair Microwave SIEMENS – St. Gallen

2. Diagnosis One of our Siemens-trained technicians will carry out a thorough on-site inspection of your microwave oven. This includes a systematic check of the magnetron (the vacuum tube responsible for generating microwaves), the high-voltage transformer, and critically the HV capacitor and HV diode. It is essential to stress that the HV capacitor retains a dangerous electrical charge even when the oven is switched off — this is precisely why Siemens microwave repairs should never be attempted without specialist training. Our technicians follow strict safety protocols at every step. Following diagnosis, you receive a full, transparent quote before any repair work begins. No hidden fees, no surprises.

3. Repair Once you approve the quote, our technician proceeds with the repair using original or certified-compatible Siemens spare parts. Common interventions include replacing a burnt-out magnetron, renewing a failed HV capacitor, resolving a blown internal fuse caused by a voltage surge, or restoring the turntable's motor so your iQ700 model operates exactly as Siemens designed it. Door safety interlock issues — where faulty mechanical catches prevent the oven from operating — are also diagnosed and corrected with precision.

4. Guarantee Every repair carried out by Swissrepair is covered by our repair warranty. This means that if the same fault recurs within the warranty period, we return and resolve it at no additional cost to you. It is our concrete commitment — not just a promise.
