# What Happens When Refrigerant Leaks From a Refrigerator

## What happens when freon leaks from refrigerator? Less than you fear, and more than a top-up can fix

Two questions hide inside this one. The safety question is the one people type. The useful question is the one underneath it.

## The safety answer

The charge in a domestic refrigerator is **small** — tens of grams, not kilograms.

Many current machines use isobutane, which is flammable in quantity. In the quantity a refrigerator holds, in a normal kitchen, a leak is not a health emergency. The sensible response is:

- **ventilate** the room;- **no naked flames** while you do;- **do not run the appliance**;- book it.

It is not a reason to leave the house, and anybody telling you otherwise is either confusing it with a gas supply leak or selling something.

## The answer that actually saves money

**A sealed system does not consume refrigerant.**

That sentence is the whole point of this page. The system is a closed loop — compressor, condenser, capillary, evaporator, back to the compressor — welded shut at the factory. Nothing is used up. There is no service interval. On most domestic machines there is not even a port to add gas through, because there is no legitimate reason to.

So: **if it is low, it is leaking.**

Which means adding more refrigerant is not a repair. It is a delay with a price on it. The machine cools for a few weeks or months, the gas escapes through the same hole, and you are back where you started — usually with a system that now has moisture or air in it as well, which makes the real repair harder.

If somebody offers to "gas up" your refrigerator without finding the leak, that is the moment to ask a second question.

## What a real repair involves

Four steps, and they are why the figure is what it is:

- **Recover** what refrigerant is left. It is not vented to atmosphere.- **Find and repair the leak.** Joints, the evaporator, a line passing through the cabinet. On coastal installations, corrosion is a genuine cause.- **Evacuate** the system — pull it down to remove air and moisture, because both ruin a system that has been opened.- **Recharge by weight**, to the figure on the appliance's own plate.

This is regulated work. It requires certification and equipment. On this site it starts at **from $650**, and it is the only repair here where we will argue against doing it.

## The leak that cannot be repaired

A leak **inside a foamed cabinet wall** — where the tubing runs through the insulation — frequently cannot be reached at all.

You will be told that plainly rather than sold an attempt. It is the point at which the machine's value decides the answer, and on a small freestanding appliance the answer is usually replacement.

## How to tell this apart from a defrost problem

They present similarly and they cost very differently, so it is worth knowing the rough test.

**Defrost problem:** the freezer still freezes, the refrigerator goes warm, and manually defrosting the machine for twenty-four hours makes it work again — for a few days.

**Sealed system:** the compressor runs constantly, neither compartment gets properly cold, and the condenser (behind or beneath the machine) stays **cool** when it should be warm. Manual defrosting changes nothing.

The first is a heater, a sensor or a fan, at from $185. The second is this page.

## The cheapest thing you can do about any of it

Clean the condenser. Twice a year on this coast, more if you are near the water or have pets.

A condenser loaded with salt and dust makes the compressor work harder and hotter for years, and heat is what ages a sealed system. It is the least glamorous maintenance in the kitchen and it is the one that prevents the most expensive repair on this site.
