What is Refrigerant Gas?

Refrigerant gas is the liquid or gas used to regulate the temperature inside a fridge. It absorbs the heat from the fridge's interior and releases it outside, thus lowering the temperature inside. As the gas keeps circulating through the condenser and evaporator, it helps keep the fridge cool and fresh.

How to Know When Your Fridge Gas is Low

There are several signs that your fridge gas is low:

  • The fridge takes longer to cool
  • The fridge stops cooling altogether
  • The compressor keeps running non-stop
  • You notice frost buildup on the evaporator coils

Ensure you confirm that low gas is the problem before refilling.

How to Refill Your Fridge Gas

Refilling your fridge gas is a task best left to a professional. However, if you know your way around the appliance, you can follow these steps:

Step 1: Switch Off the Power

Before you attempt any repair or maintenance task on your fridge, ensure you unplug it from the power source. This will protect you from electrical harm or shock.

Step 2: Remove the Old Gas

You'll need to remove any remaining gas from the fridge. This is a delicate process, and you should take extra care to avoid any leaks. Afterward, dispose of the old gas correctly or recycle it as required by your local laws.

Step 3: Check for Leaks and Damage

Before adding new gas, check the fridge for leaks and damages that might compromise the gas' performance. This is a critical step that will save you from future problems.

Step 4: Add the New Gas

Now it's time to add the new gas. Typically, fridge gas is stored as a liquefied gas and must be inserted through the compressor. Note that the amount varies from one refrigerator model to another, so consult the manufacturer's manual for the quantity to use. Additionally, add the gas slowly to prevent pressure buildup, which might damage the compressor.

Step 5: Test and Clean

After refilling the gas, test the fridge to ensure it's working correctly. Then, clean any residue or spills that may have occurred while refilling the gas.


Refilling your fridge gas is not only a technical process but also a hazardous one. If you're not confident about the process or your knowledge in this field, seek the services of a certified technician. Remember, using the wrong type or quantity of gas can damage your fridge, compromising its performance and cost you more than you'd have spent on professional repair.
