  • Our take on the Whirlpool WMCS4321TB Countertop Microwave

    The Whirlpool WMCS4321TB is a 1.1 cu. ft. countertop microwave with sensor cooking, five auto cook modes and ten power levels. Its standout features are a CleanRelease non-stick interior, a dishwasher-safe turntable plate and a steam clean cycle, which make everyday cleanup easier than in most microwaves at this size. A glass door and dark interior give it a cleaner look than basic white-box rivals. It suits households that reheat and defrost often and want preset cooking without watching the clock.

    Questions and answers

    Does sensor cooking really prevent overcooking?
    The sensor measures steam and ends the cycle when food reaches the set point, which helps with leftovers and vegetables. Dense or unevenly shaped food may still need a stir or extra time.
    How do I clean the interior?
    The CleanRelease non-stick coating wipes down easily, and the steam clean cycle loosens dried spills. The turntable plate is dishwasher-safe.
    What can the auto cook modes handle?
    The five auto modes plus popcorn and melt/soften cover common tasks like reheating plates, cooking vegetables, melting butter or chocolate and softening cream cheese.
    Is it big enough for a family dinner plate?
    A standard dinner plate fits on the turntable, but wide platters and large casserole dishes may not. Measure your most-used dishes against the 1.1 cu. ft. cavity.
    Does it need special installation?
    No. It is a countertop unit that plugs into a standard outlet; just leave clearance around the vents.
    Can I turn the turntable off?
    The turntable is the standard rotating plate; there is no separate off switch listed, so plan on using it for even heating.
