Issues of Catering Refrigerators and Freezers:
The job of the catering refrigerators and freezer is to keep the food out of the danger zone and keep the fresh food available in the right time. The commercial refrigerators plays a very critical role in success of a business. Maintaining the refrigerators has a lot of importance in making sure that the refrigerators functions properly and efficiently.
Maintaining and repair of the refrigerator is not a very cheap thing so it is always better if you are able to solve the small problems yourself. This will not only help you save a lot of money but will also enable you to solve problems before they get worse.
Here are some of the common issues that your commercial fridges and freezers:
If the door of the refrigerators is not closing properly:
The properly closing of the door depends upon the door seals or the gaskets and this is one of the common issues of catering refrigerators and freezers. The lining which goes around the refrigeration equipment doors is called the door gasket. It is lined across the entire door so that the cold air is trapped inside the refrigerator. Its basic function is to create a very tight seal.
When to replace:
There are certain signs that tell you that you need to replace the gaskets:
- If the frost starts building up on the shelves and the food.
- The latch that is present on the walk-in does not latch properly.
- If you can feel the cold air coming out of the refrigerator.
- There is temperature fluctuation.
- Cracks are appearing in the lining.
- Gaskets is separating from the refrigerator.
- The material of the gasket starts to harden and is always compressed.
Maintaining the gaskets:
The gasket groves should wiped regularly. Cleaning the gaskets regularly helps in prolonging the life of the gaskets. It also keeps the unwanted grime from getting in to contact with the food.
Refrigeration is not working:
The running of the catering freezers that comes from Koolmax depends a lot on the functionality of the thermostat. If the refrigerator is not running at all then there is a chance that the thermostat is not working properly.
There are two ways that a commercial refrigeration thermostat fails to work:
Thermostat in open position:
If the thermostat is in the open position then the catering refrigerators from Tefcold will not work at all. In order to check it you should remove the screws of the evaporator housing and pull out the housing. Remove the wires attached to the thermostat. Connect he two wires together and tape it together with the electrical tape. Turn the appliance on and check if the appliance runs. If it does you need to replace it.
Thermostat in closed position:
If it is in closed position and then the catering r will run constantly and it will cause the evaporator to freeze and restrict the airflow.
Replacing the condenser fan motor:
The condenser fan motor is placed on the condensing unit. The size of motor is determined by the size of the appliance. The rotation direction is very important information to have. Rotation can be clock wise and counter clockwise. When you are replacing the motor or fan you should keep the rotation direction in mind because it should be rotated in the same direction.
Replacing the evaporator fan motor:
It is placed inside the motor. There are two types of evaporative motors:
Open winding type:
They are mostly reversible and it can be done by removing bearing housing and pulling out armature. Turn it around and shaft should be put in other direction.
Closed type:
If it fails to work you need to replace it.
