How to Check That Your Freezer or Refrigerator is Performing Optimally


Gembecki knows how important refrigeration units are to Central Florida services and that it’s essential to your business to keep them running at optimal capacity. If they aren’t functioning correctly, you could have to throw out spoiled food and other products. Further, if they are having to work too hard to do their jobs, you pay the price in higher energy costs.

We provide expert installation and maintenance for commercial refrigeration and restaurant equipment. Our Orlando HVAC repair company has certified technicians that are available around the clock to help ensure that a refrigeration malfunction doesn’t stop your business.

While we appreciate our commercial customers, we realize that you’d rather not see us if you don’t have to. That’s why we’re listing some signs that your refrigerator or freezer is not working as it should and some simple things you can check or do before you call out a Gembecki technician.

It is Not Cold Enough

  • Look at the temperature setting and test the control.
  • Make sure the air flow through the vents is not restricted.
  • Assure that there is enough room for air flow.
  • Check for air flow restrictions in vents.
  • Check the door switch and seals.
  • Test your defrost timer and heater.
  • Test the evaporator fan.
  • Clean the condenser coils.
  • Make sure the refrigerant is not leaking.
  • Ensure that the drain tube isn’t clogged.

It is Too Cold

  • Look at the temperature setting.
  • Test the temperature control.
  • Refrigerator runs continuously.

It Starts and Stops Frequently

  • Clean the condenser coils.
  • Check the outlet voltage.
  • Test the compressor relay and motor, the condenser fan and the overload protector.

It Runs Continuously

  • Defrost the freezer if needed.
  • Check the door switch and seals.
  • Clean the condenser coils.

Note that sometimes a refrigerator will run non-stop for at least 24 hours after it has been loaded with food, when the temperature is adjusted and if the weather is humid.

Improving the Efficiency of Your Refrigerator and Freezer

There are a number of simple steps that you can take to help your refrigerator and freezer run at optimal capacity.

  • Keep it filled. That way, there is less air to have to cool and less air escapes when you open the door. If you have no need to fill it up with food, keep some large bottles or even covered pitchers of water in it. You can achieve the same effect in the freezer by stocking it with bags of ice.
  • Keep the temperature at the optimal setting. For the refrigerator, this is 37 to 40 degrees Fahrenheit. For the freezer section, it is 5 degrees and for standalone freezers, it is zero. If you don’t know the temperature, you can buy a refrigerator thermometer.
  • For refrigerators, this includes defrosting if you don’t have a frost-free unit. You should not let more than a quarter of an inch build up in the freezer. It makes the unit have to work harder. You should also vacuum your condenser coils every six months.

Additional Tips for Stand-Alone Freezers

  • De-ice your freezer once a year to help it run more efficiently.
  • Freezers should be kept on a level surface to keep all of the parts working and the oil draining properly.
  • Do not place a freezer in an enclosed area. This will cause it to heat up, meaning that it will have to work harder.
  • Be sure to use a power cord specifically designed for appliances, and use a surge protector with it. That way, if the electricity goes out, you won’t be looking at a freezer full of spoiled food.

If our certified Gembecki technicians install your freezer, you can be assured that they will help you choose a spot where it will operate at its optimal level.
