Understanding Common Commercial Cooler Failures
Your commercial cooler is one of the most essential—and energy-intensive—pieces of equipment in your establishment. It's often ignored until a problem emerges, but issues like failure to maintain pressure or compressor failure can lead to catastrophic product loss. These problems, along with unnecessarily high energy bills, can often be avoided with proactive maintenance and a quick response to the first signs of trouble.
A Guide to Diagnosing Your Cooler's Malfunction
We believe in empowering our clients. While we always recommend calling a professional for complex issues, the following diagnostic guide can help you understand what might be wrong and potentially solve minor problems before they require a service call.
Malfunction 1: Power is on, but the control board is dark.
- Possible Causes: Blown fuse, phase loss, or a failed control board.
- Solutions: Check your wiring and replace any blown fuses. Test the transformer's output voltage (should be ~12V). If these check out, the control board may need replacement.
Malfunction 2: The control board is on, but the compressor won't run.
- Possible Causes: A tripped relay, safety switch shutdown, defective contactor, incorrect set-point, or a tripped thermal overload.
- Solutions: Reset the relay after identifying the cause. Check and reset the safety switch. Test the contactor and coils. Verify the temperature set-point is correct. Allow time for the compressor to cool if it has overheated.

Malfunction 3: The system is showing high discharge pressure.
- Possible Causes: A dirty condenser coil, a non-functioning fan, or an overcharged system.
- Solutions: Clean the condenser coil thoroughly. Inspect the fan motor and its electrical circuit. If overcharged, a technician must reclaim the excess refrigerant.
Malfunction 4: The system is showing low suction pressure.
- Possible Causes: A refrigerant leak, a plugged suction filter, or a dirty/iced evaporator.
- Solutions: Check for leaks, repair them, and add the correct charge. Replace a plugged suction filter. Clean and defrost the evaporator coils.
Malfunction 5: Heavy frost is building up on the evaporator fins.
- Possible Causes: Defrost cycles are too infrequent or not completing fully.
- Solutions: Perform a manual defrost and then adjust the defrost cycle frequency and duration on the control system.
Malfunction 6: The high-temperature alarm is active.
- Possible Causes: Excessive door openings, poor refrigerant performance, or heavy frost buildup.
- Solutions: Reduce door opening frequency and duration. Address the underlying refrigerant issues (see malfunctions 3 & 4). Perform a manual defrost.
The Importance of Evaporator and Condenser Maintenance
Two of the most critical components in your system are the evaporator and condenser coils.
-
The Evaporator Coil: This is where the cooling happens. Moisture from the air freezes onto the coils, and if the defrost cycle isn't working properly, this ice builds up into an insulating blanket. This forces the compressor to work harder and longer, driving up energy costs and eventually failing to maintain temperature. Furthermore, if the drain line is blocked, water can back up, freeze, and cause serious structural damage to the unit.
-
The Condenser Coil: This coil releases heat from the system. If it's located in an enclosed space with poor ventilation or if the coil itself is covered in dust and debris, it cannot effectively dissipate heat. This causes the compressor to run at a higher pressure, increasing power consumption and the risk of failure. Ensure your condenser is in a well-ventilated area and that the coils are kept clean.
