If you want quick, dependable response I recommend someone other than Sears.
The service department was unwilling at any time to expedite or escalate my call to get a technician out sooner. I was inconvenienced twice by this unit and received very little in return.
I have never heard a staff of people use the term "not our policy" so frequently. They said all of the warm, feel good things like 'we understand your frustration' and 'we are so very sorry'. It was just a routine.
I will never use sears for service again, and I certaintly will never buy a sears product because I know they will not stand behind it.
