How often should a refrigerator door gasket be replaced?

A refrigerator door gasket typically lasts 5-10 years, but its lifespan depends on usage and maintenance. It should be replaced immediately if you notice cracks, tears, hardening, or a loss of seal, which can lead to inefficient cooling and higher energy bills.

Can a faulty door gasket increase my electricity bill?

Yes, a faulty door gasket can significantly increase your electricity bill. When the seal is compromised, warm air enters the refrigerator, causing the compressor to work harder and run more frequently to maintain the desired temperature. This continuous operation consumes more energy.

How can I test if my refrigerator door gasket is sealing properly?

A common test is the 'dollar bill test.' Close the refrigerator door on a dollar bill, then try to pull it out. If it slides out easily, the seal is weak at that spot. Repeat this around the entire door. You can also visually inspect the gasket for cracks or deformities.
