When a commercial refrigerator does not cool enough, the cause can be one of several things. It could be a blown fuse or tripped circuit, or a problem with its thermostat. In the latter case, it is important to have the device checked by a qualified technician. A knowledgeable technician can diagnose the problem and get it back up and running in no time.
The first thing to do is to check the thermostat. Make sure it is properly tuned and accurate. The next step is to have the compressor repaired or replaced, if necessary. Another common cause of commercial refrigerators not cooling is a noisy compressor. This part of the commercial refrigerator distributes the refrigerant and coolant through the evaporator and condenser. Dirt and dust can choke the compressor, so cleaning the compressor coils is essential to prevent future damage.
You may also consider contacting a certified repair service. A trained service technician can make sure your commercial refrigerator is running smoothly and ready to go 24 hours a day. This saves major repairs down the road. Regular maintenance is also important to keep your commercial refrigerator in good working order. This will save you money in the long run by reducing the need for larger repairs.
If the compressor is not running, check to see if something is blocking the fan. If nothing is blocking the fan, it should spin fine. If not, replace the motor. You can get one from your refrigerator manufacturer or appliance parts distributor. To replace the fan, remove the mounting bracket that holds the old motor to the blades. Then install the new motor.
