Refrigerator type and age did not affect the ability to keep a constant temperature, but location was important. Refrigerators in temperature-controlled environments maintained the optimum coolness range better.
So, have you checked the temperature in your refrigerator lately? The thermostat may need to be adjusted, or perhaps you need to do some general maintenance.
Here are a few pointers for improving refrigerator performance:
* Vacuum vents and coils. Dusty coils have to work harder to cool the refrigerator.
* Clean the drip pan beneath the refrigerator.
* Clean the drain of automatic-defrost models. To clear the drain tube, remove the stopper and insert a pipe cleaner into the opening; flush with soapy water, then empty and clean the pan.
* Wash gaskets that seal the doors with soapy water. Occasionally test gasket condition by attempting to slide a sheet of paper between the seal and the refrigerator wall. If the paper slips in, the seal is not tight enough, and the gasket needs to be replaced.
* Do not position a refrigerator or freezer in direct contact with hot appliances because this will make the compressor work harder.
* Regularly defrost manual-defrost freezers to keep frost buildup under 0.25 inch.
To prevent treatment errors with animal health products, store the products approved for use in lactating (milking) cows on a separate shelf in the storage unit from those for dry cows. Label the shelves to help maintain an organized storage unit.
Store products other than antibiotics, such as wound dressings and injectable vitamins, on a third shelf along with needles and other instruments used in the treatment of animals. However, food and beverage items cannot be stored in the same refrigerator as the medicinal products, so don't combine them.
And, when you grab that next "cool one," remember to check the operation of those other refrigerators. Get a reliable thermometer and check that all- important cooler storing your meds and supplemental injectable products.
