As the UK endures a heatwave with temperatures reaching 35°C in some areas, experts are urging Britons to check their fridges, which are working overtime to maintain internal temperatures. Hisense appliance expert Matthew Glynn explained: "When temperatures rise during a heatwave, your fridge has to work harder to keep the inside temperature stable because the surrounding air is warmer. The surrounding warmer air also means the internal temperature of your fridge is likely to warm up quicker when the door is open, meaning food can spoil much more easily."
Adjust Fridge Temperature
To help fridges cope, Glynn recommends temporarily lowering the temperature. "I'd recommend dropping it towards the colder end of its range, around 2°C if your appliance allows. This gives your fridge more capacity to cope with the warmer ambient temperature and helps prevent the internal temperature from creeping up when the door is opened." Official guidance advises keeping fridges between 0°C and 5°C, and using a fridge thermometer to verify.
Prevent Food Spoilage
If a fridge struggles to stay cool, the risk of food spoilage increases. Beyond adjusting the temperature, adopting good habits can help. Keep the fridge door closed as much as possible; every opening lets warm air in and cold air out, forcing the appliance to work harder. Avoid overcrowding to allow cold air to circulate. Let leftovers cool before refrigerating, as warm food raises internal temperature. Organize shelves to promote air circulation and ensure easy access to perishable goods.
