Overview

The Whirlpool WMCS3019RB is a 0.9 cubic foot, 900-watt countertop microwave in black, with a turntable, Steam Clean function and preset express buttons for everyday reheating and defrosting.

It is sized as a secondary or small-kitchen microwave rather than a full-size unit, and Whirlpool leans on steam cleaning instead of scrubbing for routine mess. Several buyers used it as a stopgap during a kitchen remodel and were satisfied with the fit and output for that role. A child safety lock is built in and can be disabled, though a couple of owners without kids found it a nuisance to work around.

  • 900 watts across 10 power levels
  • 0.9 cubic foot capacity
  • Steam Clean cavity cleaning function
  • Express buttons for quick start cooking

Who it's for

Suits an apartment, dorm, office or temporary kitchen setup where counter space is limited and 900 watts covers reheating and basic cooking. Less suited to anyone who cooks full meals in the microwave regularly or wants a unit without a lock feature at all.

Pros and cons

Pros
  • Fits tight counter or cabinet space at 0.9 cu ft
  • Steam Clean loosens splatters without scrubbing
  • Dishwasher-safe turntable simplifies cleanup
Cons
  • Child lock can't be permanently removed, only disabled
  • One review reports inconsistent heating, burnt or frozen food
  • Lock has reportedly thrown an error requiring a power reset

Performance notes

The 900-watt output runs through 10 power levels plus a set of Auto Functions for reheating, defrosting and keeping food warm, so routine tasks do not need manual timing. Steam Clean works by heating a bowl of water inside the cavity to loosen splatters, which then wipe off rather than needing to be scrubbed. The turntable plate is dishwasher safe, and the child lock is switchable, though it has reportedly thrown an error code that required unplugging the unit to clear.
