My Kenmore Commercial frost free freezer has been running continually for the past several days. I have noticed that the food is starting to thaw slightly. It remains cold but not frozen. I have it set at 4 on the dial. I had this freezer repaired in 2012 and the mechanic put in a new sensor behind the inside back panel. Do you think that is the problem again?

Latest Questions

Hi, I have the listed Kenmore freezer for more than 12 years. It has worked fine most of the time. Recently (over the past 3 months) it is displaying the following problem: intermittently it does not work. When this happens the freezer gets warm and whatever is stored starts to thaw. When I notice that this is the case I press the inside back panel and immediately the fan comes on and cold air blows and then eventually the motor starts up and everything works fine. The freezer will then work fine for several days and then the problem recurs. Sometimes I notice that the freezer is not working but the inside is cold and everything is still frozen. When I press the inside back wall nothing happens. I figure that it is in its defrost mode. Eventually the motor comes on again. I am thinking that at those times when the freezer does not come on it seems to be unable to come out of the defrost mode. I don't know if this is correct. Any help you can provide would be appreciated. Thanks in advance.

The hole that leads to the drip pan keeps freezing. If I pour hot water down it, it thaws but refreezes in a couple of days
