A Dream Come True

The fan is a key component of any refrigerated case. It's connected to a small motor and turns to help circulate cool air throughout the case, playing a critical role in keeping the case's contents at your desired temperature. If you notice that the interior temperature of a case in your supermarket is starting to climb, there are several potential reasons for the problem. One reason could be a problem with the fan. In this situation, you'll want to replace the fan by finding a comparable one at a supermarket case parts store. There are several key details to notice as you shop, including these things.

Fan Diameter

The diameter of supermarket case fans can vary a lot. You'll want to carefully measure your case's current fan to ensure that you buy a replacement that is the exact same diameter. A fan that has a smaller diameter won't push the proper volume of air, which could affect the case's ability to reach your desired temperature level. Conversely, a fan that is too large may not fit in the housing that holds the fan, which will delay your ability to get the case up and running again. Knowing the diameter of the fan before you place your order will ensure that you get the right replacement fan.

Number Of Blades

You'll often see refrigerated case fans with different blade configurations. In general, you'll want to buy a replacement fan that has the same number of blades as your current fan. A fan that has more fan blades or fewer fan blades will move air at a rate that will be different from the original fan, which may not be suitable for your refrigerated case. Take note of the number of blades and shop accordingly.

Fan Connector

Replacing your fan is a fairly simple process. Generally, you'll remove the faulty fan by unplugging it, and then plug the new one in. You should note, however, that the connector types can vary a little between fans. You'll want to note what specific type of connector your refrigerated unit has. If possible, take a photo of the connector or have the old fan's connector in front of you when you shop for the replacement part. When you buy a replacement fan with the right type of connector, you'll be able to get the fan plugged in and have the unit running in a short amount of time.
