Repair Methods for Defects of Cake Display Cabinet (Freezer)

In the baking and retail industries, cake display cabinets play a crucial role as refrigerated display equipment. They not only ensure the freshness and taste of food but also serve as important elements to attract customers. However, cake display freezers may encounter some common defects during prolonged use. This article will provide a detailed introduction to common defects and respective repairing methods for defective cake display refrigerators and freezers.

1. Poor Cooling Performance of cake display cabinets

Cause of poor cooling performance

Insufficient refrigerant, dirty condenser, compressor failure, etc

Solution to repair poor cooling cake display cabinets:

• Check if the refrigerant is sufficient; if not, add more in time

• Regularly clean dust and dirt from the condenser to ensure effective heat dissipation

• If the compressor is faulty, contact a professional technician for inspection and repair

2. Excessive Noise of cake display freezers

Cause of excessive noise

Unstable compressor fixation, fan failure, refrigerant flow noise, etc.

Solution for repairing cake freezer with excessive noise:

• Check the fixation of the compressor; if loose, refix it

• Check if the fan is damaged or excessively dirty; clean or replace it as needed

• Noise from refrigerant flow is normal and can be reduced by properly arranging items to minimize sound transmission

3. Unstable Temperature of cake display refrigerators

Cause of unstable temperature

Thermostat failure, refrigerant system leakage, improper door seal, etc.

Solution for repairing cake refrigerator with unstable temperature:

     ● Check if the thermostat setting is appropriate; adjust or replace it if necessary

     ● Inspect the refrigerant system for leaks and repair them promptly

     ● Check the door seal for tightness; replace it if there are any issues

4. Excessive Frosting in refrigerated cake cabinets

Cause of excessive frost build-up

Dirty evaporator, excess refrigerant, too low temperature setting, etc.

Solution for repairing frost build-up:

     ● Regularly clean frost and dirt from the evaporator to ensure proper heat dissipation

     ● Check if there is too much refrigerant and release some if needed

     ● Adjust the temperature setting to prevent excessive frosting

5. Lighting Failure of cake fridges

Cause of failed lighting in cake fridges

Damaged bulb, switch failure, circuit failure, etc.

Solution for repairing the light in cake fridge:

     ● Check if the bulb is damaged and replace it promptly if it is

     ● Inspect the switch for faults and replace or repair it if necessary

     ● Check for circuit disconnection or short circuits and repair any issues promptly

6. Loose Door Seal of cake freezers

Cause of loose door of cake freezers

Aging, deformation, or damage to the seal strip.

Solutions for repairing loose door seal:

     ● Regularly inspect and replace the seal strip to prevent aging and deformation

     ● Avoid prolonged heavy pressure on the door to prevent deformation

     ● If the seal strip is damaged, contact after

● sales service for replacement promptly

7. Glass Fogging in cake display cabinets

Cause of fogging glass of cake display cabinets

The internal temperature of the refrigerated cake cabinet is usually low, while the external environment temperature is high. When warm, moist air from the external environment comes into contact with the cold glass surface, the water vapor quickly cools and condenses into water droplets, forming fog. Poor sealing of the cake cabinet can make it easier for external moist air to enter, exacerbating the fogging.

Solution for solving fogging glass of cake cabinets:

     ● Use heating film or heating wire to raise the glass surface temperature and prevent water vapor from condensing.

     ● Ensure the cabinet door is tightly closed to reduce the entry of external moist air.

Routine Maintenance of Cake Display Freezers

To ensure the normal operation of cake display cabinets and refrigerator display cabinets, in addition to timely troubleshooting, routine maintenance is also necessary. This includes:

● Regularly cleaning the surfaces inside and outside the equipment to maintain cleanliness.

● Periodically checking and replacing easily worn parts, such as bulbs and seal strips.

● Regularly inspecting key components of the refrigerant and circuit systems to ensure they are functioning properly.

● Following the operating specifications in the equipment manual to avoid malfunctions caused by improper operation.
