There’s nothing worse for any restaurant owner to come into work only to find their walk-in commercial fridge is not staying cold. However before you panic and start throwing all your food out and calling in the refrigeration engineer there are some simple factors you might need to check. Doing so will not only save you time and money, it’ll save you a great deal of embarrassment too.
Loss of power
The fact that your commercial fridge is not staying cold, mightn’t actually be a fridge problem at all. Instead it could well be because of a loss of power. Although it sounds somewhat obvious, you’ll be surprised at how many times we’ve been called out to fix a fridge only to find that it has no power. So check the power cable and sockets for signs of malfunction or wear and tear. If there are no obvious signs such as charred sockets or frayed cabling, use a volt meter to make sure that power is or isn’t getting through,
Next tip is to make sure that the thermostat hasn’t been turned up or turned down. The optimum temperature for a commercial walk in refrigeration unit is somewhere between 2°C and 7°C. Anything over this and it won’t keep food cool enough for storage purposes. Likewise anything under this and the food will freeze rather than stay nice and cool. Either way it could spoil, so make sure that your fridge is set at the right temperature.
Dust and debris on the condenser coils
Dust and debris build up on the condenser coils of your cooler can stop the fridge from cooling. The simple way to maintain it is to take a hand vacuum and remove any possible build up located around the coils. Once the coils are dust and debris free, wipe off the compressor and housing with a damp cloth.
Check door seals
Over time, door seals can perish or debris can get lodged in between, causing the seals to break. You might be surprised to know that even the tiniest of broken seals is sufficient enough to raise the temperature of your fridge considerably. If there are no obvious signs of wear and tear, a quick and easy check to make sure your seals are doing their job is to insert a dollar bill between the seal and the door itself and shut it. If you feel considerable resistance when trying to pull the bill back out, then it’s safe to say that it’s probably working fine. If it comes out all too easy or falls out without you touching it, then chances are you have a seal problem.
Sometimes if your fridge is overcrowded with stock or is placed over the fan area, it can prevent the fridge from cooling. If this looks to be the case try removing any stock that doesn’t necessarily warrant being refrigerated, or remove it away from the ventilation system.
By carrying out these quick checks first you might find the root cause as to why your commercial fridge is not staying cold, and be able to do something about it yourself. If on the other hand you can’t locate the problem, then at least you know you’ve done all that you can before calling out the pros.
