  • Do I need to recalibrate my temperature alarm, thermometer, data logger, or other monitoring equipment?

    We highly recommend recalibrating all monitoring equipment as needed, usually every two years. Factors such as room temperature, humidity, dust buildup, and natural wear and tear can cause your temperature sensor to lose some of its accuracy. In addition, certain regulatory groups may have their own standards regarding calibration.

  • Why isn’t my refrigerator getting cold?

    There are several possible explanations to consider if your refrigerator is running too warm:
    - Always make sure that your refrigerator is securely plugged in and that the outlet has power.
    - Some units with digital controls may have an ‘on’ setting. Consult your user manual to ensure the product is turned on. 
    - Some mechanical controls have an ‘off’ setting. Be sure that your thermostat dial is not in this ‘off’ setting.
    - If you have just installed your refrigerator, remember that it will not get cold immediately. We recommend letting the unit run for 24 hours before using for cold storage
    - An empty refrigerator will not stabilize. Always make sure your unit is at least 30% full, even if you have to store water bottles or non-perishables to achieve this storage capacity.
    - Is the door opened? Make sure the doors are closed and tightly sealed. Be careful that you do not have any large items keeping the door opened. Storing heavy items on door shelves may also compromise your unit’s cooling performance, as this can weigh the door down and affect the seal.
    - Is there ice building up? Check the rear wall of your unit to make sure there is no frosty buildup. If you see ice, then it may be time to defrost the unit.
    - Make sure there are no large items blocking the airflow inside your refrigerator. If your refrigerator is too tightly packed, cold air will not circulate evenly, potentially leading to major temperature inconsistency. 
    - For units with rear condensers, it is important to keep the rear condenser clean.  Dirt and dust in the rear coils can cause issues with your refrigeration operation. For instructions, see How do I clean the back of my refrigerator?
    - The room temperature for your refrigerator to function properly should be above 60ºF and below 90ºF. If it is colder or hotter, the unit will not work effectively.
    - Your refrigerator requires proper clearance. Models designed for freestanding use require at least a few inches of space at the back and sides of the unit, and 4” at the top. Built-in models operate best with a ¼” clearance on each side and 2” in the rear.  For more precise sizing, consult your user manual.
    - The light is on: Some Summit and Accucold models have interior light on rocker switches that require the user to manually turn them on and off. Leaving the light on and closing the door will raise the interior temperature and damage stored items. Models with automatic lighting can also experience this issue if the door is not closing properly, leaving the light on at all times. To check an automatic 
    light, close the door very slowly and watch for the light to go off (typically this will occur when the door opening is under ½”).
    - Your refrigerator is in its defrost cycle: temperatures will fluctuate during this cycle.
  • Why is my refrigerator too cold?

    There are several possible reasons for your unit running too cold:
    -Make sure that your thermostat controls are not set at the maximum setting or minimum temperature. 
    - Remember that a refrigerator and freezer run most efficiently when they are at least 30% loaded. If your unit is empty or near empty, this may explain the cold temperature. Add water bottles or freezer packs to help fill the unit. These will help to absorb the cold air and improve the overall temperature stability.
    - For refrigerator-freezer models, items stored on the top shelf of the freezer section may experience colder temperatures, as they are closest to the freezer air. Do not store sensitive items in this area, particularly towards the back of the shelf.
    -If you are using a thermometer to record the temperature, make sure the temperature probe is located towards the center of the unit. It should ideally be encased in a glycol-filled bottle to best simulate the temperature of stored contents, as opposed to just the air inside the refrigerator. 
  • What is the difference between "built-in", "undercounter", "freestanding", and "counter height"?

    Units described as being "freestanding" and/or "counter height" ventilate from the rear and therefore require proper ventilation clearance from the back, sides, and top. These units will not function properly if they are fully enclosed under a counter. Units described as "built-in"  and/or "undercounter" ventilate from the front and can be installed under a counter with minimum ventilation. Always consult your user manual for complete clearance and installation information. 
  • Why does the door on my new refrigerator stick when closed?

    Gaskets on new units may need to be worked in before operating at normal suction.
