Beta-lactamase-producing bacteria (BLPB) may have an important clinical role in infections. These organisms can be pathogenic in causing the infection as well as have an indirect effect through their ability to produce the enzyme BL into their environment.
If you turn the dial to number 0, that effectively turns the fridge off. Setting the dial to 9, the refrigerator will be working at its max capability. Your personal temperature setting will depend on how much food is kept in the refrigerator. If your fridge is packed with food, it needs to be on a higher number setting to maintain a low (colder) temperature. The temperature controller dial or slider on your refrigerator is a thermostat. It kicks the compressor on when the refrigerator is not cold enough.
My Kenmore refrigerator model number is 106.70182000. My refrigerator was dripping quite a bit of water in the back of it, yet was working properly despite that issue. I checked the drip pan in the back and it was dry, and the fan was running good. I took all items out of freezer section and found a lot of ice build-up under the freezer cover.
