What is the most reliable microwave to buy?

The most reliable microwave to buy based on Yale Appliance service data, Consumer Reports predicted reliability, and technician surveys is Panasonic for countertop and GE and Bosch for over-the-range and built-in models. Panasonic countertop microwaves, especially the NN-SN966S and NN-SN686S with Inverter Technology, have the lowest first-year service call rates in the industry at under 3 percent, because inverter technology provides precise power control that reduces stress on magnetron and control boards, and they have simple, robust designs with fewer failure points. For over-the-range microwaves, GE microwaves like the JVM6175SKSS and PVM9005SJSS are most reliable with service rates around 4 to 5 percent, large parts availability, and strong ventilation. Bosch over-the-range and built-in microwaves like the HMV8053U also have service rates under 5 percent and excellent build quality. LG and Whirlpool microwaves are also reliable at 4 to 6 percent. Brands to be cautious with include some ultra-cheap private-label brands like Magic Chef and Comfee that have service rates over 15 percent and poor parts support. To maximize reliability, choose a model with simple mechanical controls or proven touchpad, avoid excessive use of high-power extension cords, ensure proper ventilation clearance of at least 2 inches around countertop models, and clean interior regularly to prevent magnetron damage from food splatter. Most quality microwaves last 7 to 10 years.
