We all know how cost-effective regular maintenance of your equipment can be. Having a broken down piece of equipment can have a huge impact on your business, especially if your equipment is a commercial refrigerator. With a fluctuating temperature or just a complete failure, this can lead to massive amounts of lost revenue and stock alike. At Green cooling, we have put together this blog to provide you with 4 common faults to look out for to ensure that you don’t get caught out. 

Build-up of ice

If a refrigerator becomes too cold in its temperature and reaches under 0°C then ice will start to appear. This shows that your fridge is too cold and will need looking at. The reason for this could be a malfunctioning evaporator, thus causing this build up, requiring a defrost from either yourself or one of our technicians. We recommend monitoring the levels of ice in your fridge and removing builds ups also. 

If you spot that only part of the evaporator coil is suffering from this problem, then your refrigerator may be suffering from low charge. You should check the pressures and sub-cooling yourself or rely on our commercial refrigeration repair service.


The primary function of a commercial refrigerator is to keep child food and drink at an ambient temperature. Keep food at the correct temperature to ensure safety and convenience for your clients/customers. With this in mind, the temperature of your refrigerated display cabinet should be one of the first checks that you make, making sure your products are being kept fit for public consumption.

When you think of fridges, the worst-case scenario you think of would be the refrigerator getting too hot. But also if the food or drink gets too cold, this can also cause some safety problems. By having a temperature lower than required, your food will take time to defrost when with the customer.

By regularly checking your temperature (especially on warm days) with a thermostat to see it is at the ideal temperature, which for pre chilled food and bottled drinks is +1°C – 9°C. If your temperature is considerably above or below these figures, then you should look to contact our commercial fridge repair service, so you help get your refrigerator up and running as soon as possible.

4 Common Faults to Spot With Your Commercial Refrigerator

Checking Compressors

Compressors are the heart of your commercial refrigerator and keeping them in tip-top condition is very important. We recommend that you check your compressor every 90 days to ensure optimal capacity. You want to avoid the compressor getting gunked up with dirt, grease or even hair. You should also check the temperature of your compressor to ensure it is keeping the refrigerator cool. If you have any questions regarding how to check the temperature of your compressor, call Green Cooling today for more information. 

Lighting issues

If you spot any problems with the bulbs in your multideck display cabinets then we recommend that you get them checked out straight away, as they are not only affecting your refrigerator’s performance but also its usability. None of your customers will want to buy anything that has been in a fridge that has been faulty. 

Before you go about replacing any bulbs, make sure you know exactly which kind your fridge requires. If you need any assistance with this, we would be more than happy to help.
