Oct 25 (Reuters) - Whirlpool Corp WHR.N tempered its full-year profit forecast on Wednesday, signaling softening demand for its washing machines and kitchen appliances amid a cost-of-living crisis and sending its shares 5% lower in extended trading. Consumers are cutting spending on pricier discretionary items as the cost of living rises in the United States and a series of interest rate hikes over the past year to bring down stubbornly high inflation stokes fears of an economic slowdown. However, the company posted third-quarter adjusted profit of $5.45 per share, above market expectations of $4.25, according to LSEG data.
