Often the problem is down to clogged condenser coils, or due to worn our door seals. Condenser coils carry hot gas and are key to keeping a commercial fridge working properly. But sometimes the coils get clogged and the gas doesn’t travel through properly, stopping the fridge from cooling properly.
Door seals can also wear and tear with time and overuse, allowing cool air to escape. Damaged seals will also stop your refrigerator or freezer from keeping cool.
