Commercial refrigeration is crucial for various businesses in Geelong, from restaurants and cafes to supermarkets and convenience stores. However, like any complex system, commercial refrigeration units can encounter issues that, if not promptly addressed, can lead to costly repairs, spoilage, and loss of business. Here’s how to identify and address some of the most common problems in commercial refrigeration.

Common Problems in Commercial Refrigeration

1. Temperature Fluctuations

Identification: If your refrigeration unit is not maintaining a consistent temperature, you might notice food items thawing or freezing unexpectedly. Temperature inconsistencies can often be detected by placing thermometers at different locations within the unit and monitoring for significant variations.

Causes: Common causes include malfunctioning thermostats, clogged condenser coils, or refrigerant leaks.


  • Thermostat Calibration: Ensure the thermostat is accurately calibrated and functioning correctly.
  • Clean Condenser Coils: Regularly clean the condenser coils to ensure efficient heat exchange.
  • Check for Leaks: Inspect the system for refrigerant leaks and repair them promptly. Low refrigerant levels can cause the unit to struggle in maintaining set temperatures.

2. Ice Build-Up

Identification: Excessive ice build-up on the evaporator coils or inside the unit is a clear sign of trouble. This can lead to reduced cooling efficiency and even complete system shutdown.

Causes: Ice build-up can occur due to high humidity levels, frequent door openings, or a faulty defrost system.


  • Defrost System Check: Ensure the defrost system is working properly and defrost the unit regularly if it is a manual defrost model.
  • Door Seals: Check and replace door seals if they are worn out to prevent warm, humid air from entering the unit.
  • Reduce Humidity: Implement humidity control measures within your storage area.

3. Noisy Operation

Identification: Unusual noises, such as buzzing, rattling, or hissing, coming from the refrigeration unit indicate underlying issues.

Causes: Noise can stem from several sources, including loose components, failing motors, or refrigerant leaks.


  • Inspect Components: Tighten any loose components and ensure fans and motors are securely mounted.
  • Lubricate Moving Parts: Regular maintenance, including lubrication of moving parts, can prevent wear and tear.
  • Professional Inspection: Have a professional inspect and service the unit to identify and fix motor or compressor issues.

4. Water Leaks

Identification: Puddles of water around the refrigeration unit indicate a leakage problem, which can lead to floor damage and safety hazards.

Causes: Water leaks are often due to blocked drain lines, excessive condensation, or faulty door seals.


  • Clear Drain Lines: Regularly check and clear the drain lines to ensure proper water flow.
  • Condensation Control: Maintain proper humidity levels inside the unit to reduce condensation.
  • Seal Inspection: Inspect and replace door seals if necessary to ensure a tight fit.

5. Electrical Issues

Identification: Problems with the electrical system can manifest as flickering lights, tripped circuit breakers, or complete system shutdowns.

Causes: Electrical issues can arise from faulty wiring, overloaded circuits, or component failures.


  • Wiring Inspection: Regularly inspect the wiring and connections for signs of wear or damage.
  • Circuit Load Management: Ensure the refrigeration unit is on a dedicated circuit to prevent overloads.
  • Professional Servicing: Have a qualified technician expert in commercial fridge repair Geelong inspect and repair electrical components as needed.

Preventative Maintenance Tips

Preventative maintenance is key to avoiding the aforementioned problems. Here are some tips to keep your commercial refrigeration unit running smoothly:

  • Regular Cleaning: Clean condenser coils, evaporator coils, and fans regularly to maintain efficiency.
  • Scheduled Inspections: Schedule routine inspections with a qualified technician to catch and address potential issues early.
  • Temperature Monitoring: Use temperature monitoring systems to alert you to fluctuations before they become significant problems.
  • Employee Training: Train staff on proper usage and maintenance procedures, including how to identify and report issues promptly.
