Our Review
The LG LS23C4000 23 cu. ft. Side-by-Side is a 23.1 cu. ft. side-by-side refrigerator from LG, sitting in the $1,000–$2,000 range. With a 13.6 cu. ft. fresh-food compartment and 9.5 cu. ft. of freezer space, it's positioned for families of 4-5.
What stands out
This is squarely a mainstream model — LG optimizes for value, parts availability, and a feature set that covers what most households actually use. You won't find exotic materials, but everything that ships works as advertised.
Wi-Fi connectivity is built in — you can check fridge and freezer temperatures, receive door-left-open alerts, and (on supported models) push diagnostic codes to a service technician without a callout. Setup friction is normal; once connected, expect stable day-to-day operation from LG's app.
Layout and capacity
Exterior dimensions are 36.0" W × 70.5" H × 33.5" D — check your opening, especially the depth with handles extended. Total useable capacity is 23.1 cu. ft., split 13.6 fresh / 9.5 freezer.
Bottom line
The LG LS23C4000 23 cu. ft. Side-by-Side is a strong mainstream choice — most of what people actually use a fridge for, at a price that makes sense. Service parts are widely available.
