Overview
A 24 inch, 1100-watt microwave built to work as a standalone countertop unit or drop into an existing built-in trim kit, with 2.0 cubic feet of capacity and sensor cook presets for nine common foods. It includes three weight-based defrost programs.
Several long-term owners bought this specifically to replace a 13 to 19 year old Dacor or DCS microwave using the same built-in cutout, and most report it fits the older trim kit without modification. One reviewer's newer unit came in with a smaller overall footprint that didn't match a previous trim kit exactly, so measure your existing cutout rather than assuming a drop-in fit across all trim generations.
- 1100 watts, 2.0 cu ft capacity
- Sensor Cook with 9 food presets
- 3 weight-based defrost programs
- Standalone or built-in installation
Who it's for
Fits owners replacing an aging Dacor or DCS built-in microwave who want to reuse the existing trim kit and cutout. Also works as a standalone countertop unit for anyone who wants sensor cooking and weight-based defrost without a fancier interface.
What buyers say
From Amazon customer reviews.
Long-term owners replacing 13 to 19 year old Dacor or DCS microwaves generally confirm this model drops into their existing trim kit and matches the old unit's footprint and operation closely. A couple of buyers flag friction points: one found a newer unit's dimensions didn't exactly match an older trim kit, and another had trouble getting warranty registered after buying through a specific reseller. The automatic door lock during cooking surprised at least one long-term Dacor owner who hadn't seen it on earlier models.
Strengths and trade-offs
Drawn from this product's published specifications.
- One buyer's unit had a smaller footprint that didn't match an older trim kit exactly
- Warranty registration issues reported when purchased through some third-party sellers
- Auto door lock during cooking catches out owners who skip the manual
Performance notes
Sensor Cook reads moisture and steam to set time and power automatically across nine preset food types, while the three defrost programs work by weight for meat and poultry rather than a flat time guess. The door locks automatically once a cooking cycle starts and stays locked until you press Unlock Door, a child-safety feature that can be bypassed through the Setup menu if unwanted.
