Defrosting tips for your fridge/freezer


It's common to have a small amount of ice form at the back of the fridge but it's time to take action when you see around ½ inch of ice build-up.

This is to ensure your food is preserved at the correct temperature and to minimise energy waste.

Types of ice

  • Powdered Ice is the most common type and is formed by warm air creeping into fridge. It's usually caused by the door being frequentlyopened and closed, but it can also indicate a worn door seal.

  • Solid Ice is found more in the base of chest freezers or anywhere that water can leak and become frozen. To find out how to find a potential leak, read our article on how to fix a leaking fridge.

Defrosting tips


Most modern fridges and freezers are frost-free but older models will need regular defrosting to prevent the build-up of ice.

You should always defrost if the ice becomes 3mm or more thick.

  • Before you begin defrosting, make sure you store any chilled/frozen foods in a cool place. To be safe, wrap frozen foods in newspaper and pack them all together in a box (or try asking a neighbour if you could place it in their fridge-freezer for a few hours)
  • Unplug the fridge/freezer, remove any drawers and place a wedge in the door to keep it open
  • Place a tray or towels at the bottom of your fridge or freezer to mop up the water as the ice melts
  • Avoid using sharp implements to remove any chunks of ice; this can lead to the evaporator at the back being pierced and stops the fridge from working
  • Once the ice has thawed, clean the freezer and drawers with warm water and a small amount of detergent. Wipe dry and replace the drawers
  • Plug the fridge/freezer back into the mains and make sure the thermostat is set correctly
  • Now you can restock with your fresh and frozen food

That should be all you need to make sure your fridge/freezer is defrosted correctly.
