Sears has filed for bankruptcy and there is some question about whether their appliance lifetime warranties will be honored. I also read that after they filed Whirlpool demanded Sears return all the Whirlpool inventory Sears had taken delivery on in the 45 days preceding the bankruptcy filing.
That's too bad, I grew up with Sears, but it appears would be wise to stay away from them now.
Ours had the one year warranty and we didn't buy an extended one. I'm sorry to see them closing but can't really say I'm surprised. The Sears stores in our area are never busy.
