Shoppers will no longer be able to buy Whirlpool, KitchenAid or Maytag appliances at Sears, following a pricing dispute that has ended a 101-year relationship between the department store chain and the country’s largest appliance maker.

Whirlpool, which announced this week that it is raising prices to make up for costlier raw materials, said it notified Sears Holdings in May that it would stop supplying appliances to the firm.

“We simply could not reach terms that were acceptable to both parties,” Marc Bitzer, Whirlpool’s chief executive, said on a Tuesday call with investors.

The dispute highlights escalating tensions between manufacturers and retailers over exactly how much items should cost. Retailers have grown accustomed to offering steep discounts to win over consumers. Manufacturers, meanwhile, say they are struggling to keep up with growing expenses and stiffening competition, often from overseas.

The news deals yet another blow to Sears, which has already closed hundreds of stores this year. Once a dominant seller of appliances, the company has lost much of its cache and market share in recent years. It has not turned a profit since 2010, and last year it reported a loss of $2.22 billion.

“Sears is breaking up with everybody – the business is in steep, deep decline,” said Mark Cohen, director of retail studies at Columbia Business School and former chief executive of Sears Canada. “They’ve lost half of their market share in the last 14 years, and vendors aren’t seeing much value in the relationship anymore.”

Sales at Sears make up about 3 percent of Whirlpool’s total revenue, Bitzer said on Tuesday. “In terms of the impact, to be honest it’s not a whole lot,” he said.

Harikesh S. Nair, a marketing professor at Stanford University’s Graduate School of Business, said tussles over price between retailers and manufacturers are common, particularly when the retailer can still offer its own house brand. “Sears already has a large private-label appliance brand, so it helps to be able to say, ‘If we can’t stock your products, we can always stock ours,’ ” he said.

Indeed, Sears characterized the decision as an effort to support its customers, encouraging associates to sell its Kenmore brand with confidence.
