Repair Freezer BOSCH – Graubünden

2. Diagnosis — Your dedicated technician arrives at your home and carries out a thorough diagnostic inspection. Bosch freezers rely on several precision components: the compressor start relay, the defrost heater and timer circuit, the evaporator fan (critical in no-frost models), and the temperature sensor. Our technician will pinpoint exactly which element has failed — whether it is a faulty start relay preventing the compressor from restarting, a defective defrost heater causing excessive ice accumulation on the evaporator, or a refrigerant leak (R290 propane or R600a) resulting in low-pressure operation and poor cooling. You will receive a clear, itemised quote before any repair work begins.

3. Repair — Once approved, the repair is carried out on-site using original Bosch components or certified-compatible parts of equivalent quality. Bosch, as a global technology leader founded by Robert Bosch in Stuttgart in 1886, maintains rigorous component standards — and our parts sourcing reflects that same commitment. Whether we are replacing a failed temperature sensor that was maintaining the wrong operating temperature, or restoring the no-frost ventilation system by freeing a fan blade blocked by ice, we work precisely and efficiently.

4. Guarantee — Every repair completed by Swissrepair is backed by a formal written warranty on both parts and labour. You can return to your daily routine with genuine confidence that your Bosch freezer is operating as its German engineers intended.
