If you’re dealing with a fridge freezer that has frozen up, you’re not alone. It’s a common problem that many people face, but the good news is that it can usually be fixed with a few simple steps. When your fridge freezer freezes up, it’s usually a sign that something isn’t quite right with the appliance. The most common cause of a freezer freezing up is a problem with the defrost system. The defrost system is responsible for melting any ice that accumulates on the evaporator coils, which allows the freezer to maintain its proper temperature.
To fix a fridge freezer that has frozen up, the first step is to defrost it. Start by unplugging the appliance and emptying the contents of the freezer into coolers or other cold storage. Keep in mind that defrosting can take several hours, so be prepared to wait. Once the freezer is completely defrosted, you can start to identify the cause of the issue. Check the door gasket for any tears or damage that may be allowing warm air to enter the freezer. Inspect the defrost timer, thermostat, and heater for any signs of malfunction. If you notice any issues, they may need to be replaced.
Another common cause of a freezer freezing up is a clogged drain. As the freezer goes through its defrost cycle, the melted ice is supposed to drain through a small hole and into a drain pan. However, if the drain becomes clogged with debris, the water can’t escape and ends up freezing. To fix a clogged drain, start by locating the drain hole. It’s usually located near the back of the freezer, behind a cover or panel. Use a small brush or pipe cleaner to remove any debris from the drain hole. You can also pour a mixture of hot water and baking soda down the drain to help dissolve any built-up ice or debris.
If you’ve tried defrosting and fixing any potential issues with the defrost system or drain, but your fridge freezer is still freezing up, it may be time to call a professional. A qualified appliance repair technician will have the experience and tools necessary to diagnose and fix the problem. They can also determine if there are any underlying issues that need to be addressed to prevent future freezing. Remember, attempting to repair a fridge freezer yourself can be dangerous, so it’s best to leave it to the experts.
