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?
It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
Digital control will not go from 0 to7.
Answer Hello James. You will need to replace the control 297282800 in the unit.
