Hamid R for Model Number Kenmore upright freezer, 16.7 cft, Model 970-187020 The freezer is only a couple of years old. Shortly after I got it (brand new) the controls locked up. A service technician came and (probably) reset something; the freezer started working and it worked perfectly for about two years. Then the same problem came back. Another tech visit to reset the control and the freezer is working quite well once again. Unfortunately, I could not talk to the repair technician as to what exactly he did. Removing power from the freezer for a few minutes or even an hour did nothing to it. I wonder what goes wrong with the unit to lock up the controls? Is there an easy way to check/trouble shoot this freezer? Is there any help you can offer to diagnose the problem?
Answer Hamid, In most cases if the control board is locking itself then the issue would be with the control board having a key that gets stuck. As for what you can do to trouble shoot. It would be a internal error in the control and would be no way to trouble shoot it. If you have the owners manual, check to see if there is a control lockout section and if it locks out again try to unlock it as it could just be where someone pushed the wrong button. Read More...
