Gathering the reviews
We continuously collect owner reviews and public discussions from major retailers and community forums, de-duplicate them, and set aside anything we can’t tie to a verified purchase.
Calculating the average
Averaged across every source we found (Amazon, AJ Madison, and other retailers). Each source counts in proportion to how many ratings it has, so a store with thousands of reviews moves the number more than one with only a handful.

What owners talk about most
“After several months of wait, we finally got the refrigerator. Initially, the ice maker didn’t work. Technician had to come few days later in order to check. They were in plans to replace ice maker, but, somehow, it started making ice. Works well. Overall, it was worth the wait. Easy to clean.”
Owners Answer
The questions shoppers ask, answered from real owner reviews and discussions across the web — not the manufacturer spec sheet. See the spec FAQ below for the official numbers.
Multiple owners report that this KitchenAid model delivers comparable performance and appearance to Sub-Zero at a substantially lower price point. Several reviewers who replaced 15–35 year old Sub-Zero units with this model express satisfaction with the value, though some note the interior layout and storage capacity are slightly less optimized than their previous Sub-Zero models.
Yes. Multiple reviewers specifically praise the quiet operation, noting that the compressor and cooling system are virtually silent even during active cycles. One owner with experience across other premium brands describes it as making "no noise at all." The ice maker does produce some noise when dispensing, though one reviewer notes the enclosed design minimizes this.
The refrigerator has a capacity of 20.9 cubic feet. Reviewers consistently praise the flexible shelving and spacious layout, with many noting ample storage on the door and in the main compartment. However, some owners who replaced older models report that despite matching exterior dimensions, the usable interior space feels smaller than expected, and the freezer drawer design has limitations for organization.
Owners consistently praise the modern, elegant design and stainless steel finish, describing it as a beautiful kitchen upgrade that complements other appliances. The platinum interior lighting is noted as attractive and easy on the eyes. Many reviewers appreciate the sleek, contemporary look and say it fits well into their kitchen aesthetic.
The ice maker is a mixed experience. Some owners report it works well and produces ice quickly, while others describe it as slow, prone to frost buildup, or prone to mechanical failure. A few reviewers note the ice dispenser design causes ice to fall back into the freezer, and some units have experienced complete ice maker failure within months of purchase. This appears to be a notable quality-control concern for some units.
Many owners report excellent long-term performance, with several units running problem-free for 12–22 years. However, some newer units have experienced premature failures including broken ice makers, failed LED lighting, and control unit failures within months to a few years of purchase. This suggests variable quality control; some units are very durable while others have early-life defects.
Yes, multiple reviewers report poor freezer lighting design. The lights are positioned in the back and top of the freezer, leaving the drawer interior dark when pulled out, making it difficult to see food labels and contents. This is described as a significant design flaw for the price point.
Experiences vary. Some owners report smooth, well-fitting doors and drawers with good flexibility in shelf configuration. However, several reviewers note that drawers fit loosely with excessive play, doors swing shut forcefully, and shelving feels cheaply made. A few mention rattling bottles on the door due to poor shelf design, and some drawers have a tendency to fall out if not handled carefully.

I love to look at it when I am in the kitchen area beautiful design.
This refrigerator is my second one. It is beautiful!!
We waited a bit for this built-in fridge that was added during our kitchen remodel. I’m so glad we did. It was worth the wait! This fridge is beautiful and has so much more space than our previous french door bottom freezer GE model (which I also loved, btw).
I just installed the refrigerator last weekend and an very happy with the performance. It's very clean and sleek inside. I love the charcoal filter inside. Lots of storage on the door. My only complaint is the vegetable drawers are a bit shallow. Overall very pleased with the…
We had a Thermador, we replaced with KitchenAide. Very comparable for almost half the price
