Douglas M Lexington , SC August 31, 2021 Appliance: Bosch Microwave Hood Combo HMV3053U/01 Bosch Microwave Hmv3053u/01: Microwave was tripping breaker. How to replace Switch. Two door switches were replaced and it works great now. Bosch said I should contact a repairman ($200 plus) and they did not have a recall on the problem. I replaced the two switches in about 10 minutes for about $20. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
