Energy Conservation Program for Consumer Products: Test Procedures for Refrigerators, Refrigerator-Freezers, and Freezers

This rulemaking amends the interim final rule for test procedures for refrigerators, refrigerator-freezers, and freezers, issued on December 16, 2010. Specifically, it amends test procedures at subpart B, appendices A and B, by incorporating changes to the interim final rule that will apply to all measurements of energy consumption of newly manufactured products starting September 15, 2014. These amendments modify the required test period for the second part of the test for products with cycling compressor systems and long- time automatic defrost or variable defrost control and adjust the default values of maximum and minimum compressor run time for products with variable defrost. These changes will ensure a more accurate measurement of the energy use of products with variable defrost control.
