How to Tell If Your Fridge Seal Needs Replacing
The rubber seal (gasket) around the fridge and freezer door is one of the most important — and most overlooked — parts of a refrigerator. When it deteriorates, warm air gets in, the fridge works harder, your food spoils faster and your electricity bill goes up. Here's how to check whether yours needs replacing.
The Paper Test
The easiest way to check a fridge seal is with a piece of paper:
- Open the fridge door
- Place a piece of paper (like an A4 sheet) half inside, half outside the fridge
- Close the door on the paper
- Try to slide the paper out
If the paper slides out easily with little resistance, the seal is not tight enough and is likely letting in warm air. A good seal should grip the paper firmly.
Visual Signs of a Failing Seal
Inspect the rubber gasket all the way around the door:
- Cracks or tears — even small cracks let air through
- Mould or mildew — the seal isn't making contact properly, trapping moisture
- Flattened or compressed sections — the seal has lost its shape and no longer forms a tight barrier
- Sections pulling away from the door — the seal has detached
Signs Your Fridge Is Working Harder Than It Should
- The motor seems to run constantly
- The fridge exterior feels warm near the door
- Frost builds up quickly inside the freezer
- Food in the fridge isn't staying as cold as it should
- Your electricity bill has increased for no other reason
Can You Fix a Fridge Seal Yourself?
Many rubber gaskets can be ordered online for $20–80 and replaced without tools — they typically press or clip into a channel in the door. Search for your fridge's model number followed by 'door seal' or 'gasket'. For older models, parts may no longer be available.
When to Buy a New Fridge
If the fridge is more than 10 years old and the seal has deteriorated, consider whether repair costs (seal + possible refrigerant check if the motor is overworked) are worth it compared to a new, more energy-efficient model.
