Steps to follow if you think your commercial refrigeration unit isn’t working

Commercial refrigeration units are generally a critical element within most food and drink or hospitality businesses. Needed for day to day operations, not only will a malfunction cause significant stress on the businesses activities, it also creates the risk for a loss of stock which can be quite a financial burden. It is important to stay on top of the health of your commercial refrigeration systems so that you don’t find yourself in a puddle of hot water (quite literally) and are left with hefty costs. Look out for the following signs so that you can resolve any issues before it is too late.

 

Temperature

The optimal temperatures for bacteria to grow and multiply is between 5 °C and 60 °C. To avoid the risk of food poisoning and to ensure that the food quality remains fresh, it is vital that the fridge temperature sits between 0 °C and 5 °C. As per health regulations (FSANZ, Food Standards Australia New Zealand) all food service businesses have to check and record the temperature of their fridges twice daily. This allows businesses to constantly monitor and ensure that the temperature remains within a safe degree. If you notice a significant variance in the temperature (especially if it moves out of the safe range) it is best to try and determine when that occurred (refer back to your temperature recordings). You may be able to pinpoint the exact moment, as perhaps someone left the fridge door ajar which allowed the temperature escape. Another area to check is the location of the refrigeration unit as commercial refrigeration units should never be placed directly against a wall, instead it should be at least a few centimetres off to allow for circulation. Also check the sealing on the doors, as this is another area that can allow air to escape. If you cannot determine why the temperature has changed, contact your local commercial refrigeration Auckland company as soon as you notice the variance as they may be able to address the issue before it starts to affect the day to day activities of the business.  

 

Power 

Having issues with the power of your appliance? Perhaps your refrigeration unit has issues turning on or maybe it constantly switches between being on and off? Quite the obvious tip but often overlooked due to how obvious it is, but check to make sure that the power switch is turned on and the cord is correctly plugged in on both ends. It could also be the power outlet that is malfunctioning so try and insert the power cord into another outlet and see if that resolves the issue. Also always avoid relying on extension leads as they tend to be unsafe when using with commercial appliances. If the issue is not resolved after checking these simple methods, contact your Auckland industrial refrigeration team. In this case, it is best to leave it up to the professionals as it involves potential electrical issues and therefore will be unsafe if you try and complete any other solutions yourself. 

 

Fan / Frost Build-Up

Are you noticing a build up of ice in your fridge or freezer? The first area to check is the evaporator fan. Allow the ice to melt off the fan (to do this you will need to turn the fridge off, so remove all items into another fridge). When checking the evaporator fan, check the coils to ensure that they are clean, if not clean them first. Another area to take a look at is the drain lines, to ensure that they are clean and clear. If all of these areas look to be fine, don’t touch anything else as it may poise the risk of creating a bigger issue. Instead, contact your local refrigeration specialists. 

 

Lighting

As annoying as broken fridge lights can be, generally they don’t affect other crucial elements of the fridge’s running, such as power or temperature. However, if a fridge light is out, it does indicate that perhaps the light bulb is broken or dead and therefore needs to be addressed as it runs the risk of burning out the light’s electrical sockets. As this issue involves electricity, the safest option is to call on your trusted Auckland industrial refrigeration team to solve the issue for you. 

 

Compressor

Commercial refrigeration compressors assist in keeping the fridge cool. The general rule of thumb to follow is to do a routine clean of the compressor every 90 days (check your fridge manual to confirm) as often you will notice that there will be a build up of dust, dirt and grime.
