Reasons Why the Fan of Display Chiller Doesn’t work
Commercial refrigerators come in two main types: Blower System and Piping System. Blower System commercial refrigerators rely heavily on fans for cooling, so if the fan inside the chiller fridge stops rotating, cold air cannot circulate properly. In such cases, if the temperature inside the chiller freezer compartment hasn’t reached the set level, the compressor will continue to run.
Encountering this situation can be concerning, but fear not. Here, I’ll outline solutions to similar issues.
Firstly, there are several reasons why the fan of a commercial refrigerator may not rotate. For instance, damage to the control switch near the door of the freezer compartment can lead to a power failure, preventing the fan from starting.
When the freezer compartment door is open, the fan door control switch pops out, automatically cutting off the power. In this scenario, pressing the door control switch should engage it. Under normal circumstances, the fan should rotate. Unless the switch is faulty, the fan won’t operate.
Have a repair technician measure the working current of the compressor; if it’s too low, it won’t run. If we listen carefully to the outer wall of the refrigerator door, we might hear the compressor’s sound, but we won’t hear the fan rotating at all. In such cases, open the freezer compartment door and press the door switch with your hand.
If the fan still doesn’t rotate, check if the door switch and fan power circuit are functioning correctly. If necessary, remove the fan, then open the front and rear covers. Finally, power up the test machine and observe its operation. Then, open the refrigerator door and press the door switch; you should see the fan inside rotating at a low speed, which might result in weak rotation.
The repair method involves opening the insulation layer of the refrigerator’s inner wall and removing the fan for inspection. If the winding resistance of the fruit refrigerator is lower than normal, it may indicate a short circuit between windings in the fan.
During the operation of the refrigerator motor, protection is mainly provided by overheating components, which can also provide protection by automatically detecting changes in current to safeguard motors with long startup times. When the decrease in motor current is not significant, the overload protection can identify a stalled state and initiate repairs.
