Sharp SMO1754JS is an over-the-range microwave featuring 1.7 cu. ft. capacity and 1,000 Watts of cooking power with 11 adjustable levels. Its integrated 2-speed, 300 CFM ventilation fan helps clear cooking odors.
Countertop models are cheap and easily replaced, while Over-The-Range (OTR) and built-in drawer models require more investment and installation effort. Wattage matters for cooking speed and evenness. Available from $299.99.
Microwaves are highly efficient and have negligible running costs. They are generally considered disposable appliances once the magnetron fails.
Common Failure Modes
Door switches often misalign or fail, preventing the unit from starting as a safety precaution. The magnetron (the component that generates microwaves) eventually burns out after years of use.

A microwave typically lasts 7 to 10 years with normal use. Over-the-range models tend to last longer than countertop units due to higher build quality. Signs of end-of-life include food heating unevenly despite correct settings, sparking during operation, a noisy or non-spinning turntable, and the door not latching securely.
