My 75BWC is 10 years old. The unit is getting power because the inside light comes on. However, the refrigerator is not running. No sound, no heat, nothing. I've not a great job of keeping it clean behind the bottom grate. Did I kill it? Would it be the motor or condenser? How could I tell? We have a kenmore wine refrigerator that is running but not cooling below 65 degrees. This has been like this for the past 6 weeks. Am unsure what may be the problem. Any suggestions?
