Whirlpool - Customer service is abysmal
Gas Range - Complaint
BENTON HARBOR, MICHIGAN -- My gas range is truly a lemon. While still under warranty, they sent out 5 incompetent repairmen. They were not going to do any thing to help until I sent them a copy of the The Magnuson-Moss Warranty Act (P. L. 93-637) which is a United States federal law (15 U. S.C. § 2301 et seq.). Enacted in 1975, it is the federal statute that governs warranties on consumer products. if the product, or a component part, contains a defect or malfunction, must permit the consumer to elect either a refund or replacement without charge, after a reasonable number of repair attempts.
I threatened legal action and was finally promised a new range.
Don't stop trying until you reach upper level management. Then, if you are very persistent, you might get some satisfaction.
