We rate refrigerators based on their thermostat performance, temperature uniformity, noise output, ease of use, energy efficiency, crisper performance, and icemaker performance (if they have one).
Every refrigerator we test gets wired with 15 temperature sensors. We then monitor those thermocouples for more than a month in one of three temperature-controlled chambers, collecting more than 5.4 million temperature readings for each fridge we test. The results tell us how well a refrigerator maintains a set temperature and how temperature varies in different areas of a fridge, so we can determine which models will keep your food fresh longer.
Our testers measure the noise when the compressor starts up and the steady hum while the fridge is running. For ease of use, we examine the fridge’s layout, controls, and lighting.
Our process includes tests for icemaker performance based on how much ice a fridge produces per day and how much it can hold in its reservoirs. We evaluate crisper performance to judge how well the crisper drawers retain moisture to keep your food fresh for longer periods of time.
We also factor in survey data from thousands of CR members to judge brand reliability and satisfaction. All of that data and more inform CR’s refrigerator ratings and each model’s Overall Score.
