    This is a great group of articles. As any restaurant owner knows, keeping your refrigeration is crucial. Not only can poorly performing refrigeration ruin product but it can lead to health problems if your establishment inadvertently uses spoiled food.

      Hi Jeff,

      Sounds like you have a loose connection – either the bulbs themselves are loose or the wires to the socket are loose or are grounding out.

    Having a problem with the temperture in a GE profile artica. The vegetable crisper is freezing the vegetables in the refrigerator, even when the settings in the refer and freezer are both set at “1”. Any ideas to correct, or is this just a product flaw?

      Hi Steve,

      Thanks for submitting your question. Unfortunately, our area of expertise on this blog is for commercial refrigeration units. I wouldn’t want to steer you wrong with a residential unit. I would recommend looking up troubleshooting tips on GE’s site.

      Hi Patty,

      Check the door gaskets first – if they are worn or cracked then you may be getting temperature fluctuations due to leakage. If the gaskets are good then I would replace the thermostat. See this Back Burner article for more information on replacing thermostats:

    Hello, I have a commercial refrigerator cant be any older then 5 years and in good shape. The problem I am having is I set the digital temperature to 40degrees as its always been set and the temp. just keeps dropping to freezing levels. it dropped to 19 degrees. it happened once about 6months ago then once about 2 months ago. i unplugged it shook a couple wires around and everything was fine. but now it does it all the time, acting like a freezer now. any suggestions. i am formiliar with all the basic parts as i was in the HVAC field for a I dont have the unit info with me if needed let me know.

        It sounds like there’s a thermostat/temp control issue. It’s like the cooking end, where you have a runaway thermostat that does not cycle off and keeps heating. And with refrigerators, because it isn’t cycling off, it just keeps cooling. It also will prevent you from being able to defrost. We’d recommend replacing your thermostat.

    Hello..please help me..what must i do,because my comercial refrigerator is cold but not Frost..please…?

      Mr. Hakime,

      When was the last time the condenser coils were cleaned? If there’s dust & dirt build-up it will effect how the unit cools. Try cleaning the condenser coils, and see if that helps. If not, it’s likely the thermostat.

    Own a Vendor (model G319) and it’s not getting as cold as it used to. I already cleaned the condenser coils.
