Insert a sheet of paper into the refrigerator door gap: a small trick with big benefits that can significantly reduce your household electricity bill

The Paper Test: How It Works

This simple trick helps you check whether your refrigerator door is sealing properly.

What you need:

• One regular sheet of paper

How to do it:

1. Open the refrigerator door.
2. Place the sheet of paper between the door and the fridge frame.
3. Close the door normally.
4. Gently pull the paper.

What the result means:

• Strong resistance: The seal is working well.
• Paper slides out easily: Cold air may be leaking, costing you energy.

Repeat the test at different points around the door, especially corners and edges.

Why a Weak Seal Costs You Money

A faulty door seal allows warm air to enter the refrigerator constantly. This causes:

• Longer compressor run times
• Higher electricity consumption
• Increased wear on the appliance
• Reduced food freshness

Even a small gap can increase energy use by a noticeable amount over a year.

Big Benefits from a Small Fix

If the paper test shows a problem, the solution is often simple and affordable:

• Clean the gasket: Dirt and food residue can prevent proper sealing.
• Realign the door: Sometimes hinges loosen over time.
• Replace the door seal: This is usually inexpensive compared to buying a new fridge.

Fixing the seal can reduce energy consumption, extend the appliance’s lifespan, and lower your electricity bill—without changing your daily habits.
