If your commercial fridge is malfunctioning, you may be wondering what the issue might be. This article will explore some of the issues that can affect commercial fridges. Read on to find out more.
Jammed or broken motor
One cause of a malfunctioning commercial fridge may be a defective motor. The motor is typically located on the back of the refrigerator. It is the job of the motor to drive a fan which draws air over the compressor and coils so heat transfer can occur. It is the transfer of heat from inside the fridge to the atmosphere outside via the coils which allow for the proper operation of your refrigerator. If debris builds up in the motor, it may become overheated or jammed. If the motor suddenly stops working, you will probably notice that your fridge suddenly sounds very quiet.
Defective door seals
Sometimes, there could be problems with the door seals. For the door to close properly, the seals on the hinges have to be sealed tightly. If the seals are not working correctly, then the cool air inside your fridge will escape. As well as creating a situation in which the food inside can spoil, this fault can also cause the motor and compressor on the unit to work overtime, increasing the chance that they too will fail. It is a great idea to periodically run your hand around the edge of the door to check the seals.
Commercial refrigerators are fitted with a thermostat which controls the temperature of the air inside the fridge. The thermostat is an electronic device that prevents the refrigerator from getting too cold or too hot. If the thermostat malfunctions, it may not take the correct temperature readings. If the thermostat unit readings are too high, this could then cause the fridge to run all the time, which could lead to excess energy costs and the risk of a fire. If the false thermostat unit readings are too low, the fridge may not power up when it should causing the fridge to heat up to a point which spoils the food inside. Performing regular temp checks can help you to spot this issue before it becomes serious.
Another potential problem is a leaking condenser. Condensers are found on the back of the refrigerator. These are pipes that circulate coolant. If the condenser begins to leak, it could start causing damage to nearby areas. If the condenser is leaking, the coolant loss could seriously impact the function of your commercial fridge. Signs of a leaky condenser include a pool of liquid at the back of the appliance.
