Install fridges and freezers in a dry, well ventilated room. These appliances should not be installed in direct sunlight or near a heat source such as a radiator.
Regularly defrost your freezer if it is not “frost-free.”
Occasionally clean the rear of your fridge or freezer and make sure that the drainage hole is clear.
Keep the sides and back of your fridge clear from debris such as old carrier bags or newspapers.
