From Google's AI Overview:
"While most U.S. states primarily focus their lemon laws on automobiles, some states and federal laws offer protections for consumers with defective appliances. The Magnuson-Moss Warranty Act, a federal law, applies to products like appliances costing over $25 with a written warranty. If an appliance under warranty has persistent defects after multiple repair attempts, consumers may have legal recourse. "
Since states provide additional laws, it is useful to see what protections they provide. We came very close to having a freezer returned (to Sears) and refunded under lemon laws. I forget if it was a Texas or federal law.
