The sensor appears to be a NTC type thermistor (Negative Temperature Co-efficient) which means that as the temperature goes up the electrical resistance value of the thermistor goes down. Have you tried using a thermometer to check the temperature in the freezer if the temperatures you’re seeing are shown on a control panel, just in case there is an error in the display reading?Ĭheck if the temperature sensor is OK. The same with the defrost sensor as it shouldn’t really go above 0 deg C. 22 C is a bit cold so it may be a faulty temp sensor in the freezer. 0 deg., it signals the control board to end the defrost cycle by turning off the heater and to restart the compressor and the evaporator fan again to drive the temp back down again to the set temperature. When the set temp of the defrost thermostat (or sensor) has been reached i.e. Really it should not rise above 0 C as you don’t want the frozen food to even begin to thaw. cooling is stopped and temp rises in compartment and the defrost heater is turned on to melt the ice build up on the evaporator unit. The defrost cycle takes about 15-25 minutes and during this time the compressor and evaporator fan are both stopped i.e. If only once every 8-10 hours it may just be the defrost cycle in operation If you believe your fridge has a fault that causes it to be too cold or too warm, call us at Glotech for a fridge repair today.What is the make and model number of the freezer?ĭo you mean that the temp goes from -22 to 2 and then back to -22 centigrade again? If you have a broken thermostat, your fridge temperature will not be adjustable. Check the seal around the fridge door – if it’s not fitted properly, this means that cold air can escape easily. Poor organisation can stop the proper airflow around a fridge, meaning that some parts of the fridge are colder than others. There’s a range of reasons why your fridge could be at the wrong temperature. Why Is My Fridge At The Wrong Temperature? Today, -18☌ is the accepted standard for freezing food. However, if food is frozen at lower temperatures, it will slow the bacteria growth even further, and preserve the Vitamin C content in frozen vegetables. When freezers first became common in homes, food was frozen at -10☌. In order to measure the temperature accurately, keep a thermometer on the middle shelf of the fridge, or check out these other ways to measure fridge temperature.Ĭontrary to popular opinion, freezing food does not halt the growth of bacteria – it will just slow it down. Choosing setting 5 will make your fridge the coldest. Therefore, the higher the setting, the cooler the fridge will be. The numbers on the fridge’s temperature dial indicate the refrigerating power. Some fridges don’t show the temperature but work on a setting that is listed from 1 to 5. What do the numerical settings on the fridge mean? Taking into account the temperature drop from the opening and closing of the fridge door, the fridge should be set at a temperature between 1-5☌. According to the UK food standards agency, the ideal fridge temperature for food is 8☌ and below. When food is refrigerated, the growth of bacteria is slowed. The spoiling of food is inevitable, as microscopic organisms are constantly feasting on our food. A recognisable sign of bad bacteria is mould – food with mould is not safe to eat. Good bacteria is added to food at the point of manufacture to make it taste better, and can often be found in items such as sourdough bread, beer and yoghurt. Ideal Fridge Temperatureīacteria is present in all food, but it can be thought of in two ways: there’s good bacteria, and then there’s bad bacteria. If these appliances aren’t maintaining the correct temperature, they’re falling short of their purpose. The purpose of a refrigerator is to slow down the growth of bacteria and the purpose of a freezer is to slow the bacteria even further through the process of freezing. A fridge that freezes your tomatoes, wilts your salad, or turns your milk into cheese is either broken or needs adjusting. If you’ve ever taken something out of the fridge and discovered that it’s half frozen or worse, lukewarm, you’ll probably be curious to know what the ideal temperature to keep your fridge and freezer is.
