A gas fridge will often only need replacing after about 15 years. Compare that to around ten years for compressor fridges, and this means value for money in the long run. But it does depend on the model you choose and how well you maintain it.
A small 100 litre LPG gas fridge uses around a third of a kilogram of gas over 24 hours, so a normal 8.5kg bbq gas bottle will last you around three weeks. A larger 2-door gas fridge, around 200 or 300 litres, will use around half a kilogram of gas per day.
Refrigerant gas in a refrigerator can last for many years, typically the appliance's entire lifespan, if there are no leaks or damage to the system.
One question that our clients often ask our refrigeration technicians is whether they need to top up their refrigerant and how often it needs to be done. Unless there is a leak in the system, the answer to this question is never. It should not need to be replaced unless something is going wrong.
Did you know that many gases in air conditioners and refrigeration systems can be extremely harmful to the environment if released? Many old refrigerants damage the ozone layer. Other refrigerants are potent greenhouse gases. They can contribute to climate change and impact human health.

The gas stays in the refrigerator life-long. It only leaks out if you puncture the icebox with a knife or sharp object when you try to remove ice. If you are patient and let the thing defrost by itself, you won't damage the evaporator and the gas will stay inside forever.
The Foodstuff Starts Getting Spoiled or at Best Starts Remaining Warmer. If you find the foodstuff stacked in your fridge has started getting spoiled or getting warmer, that's a red flag. This is the first sign of the fridge losing gas, and the rate of the loss speeds up, you can find a freezing effect.
Modern fridges rarely need regassing, however, it can happen and it's both costly and uneconomical. Usually, fridge gas doesn't run out unless the pipes are damaged or the factory welds are faulty. But there are many other more common and less expensive faults, which can also stop your fridge from cooling.
LPG Gas Fridge
LPG gas is the most efficient way to run an absorption fridge, as the LPG gas instantly produces a very hot flame. 240V power will also cool an absorption fridge well, although the heating element needs to produce the same amount of heat as a gas flame, so it is not as efficient as on LPG gas.
Signs of low freon include blowing warm air regardless of how long it's running, taking longer than normal to cool down, or having ice on the refrigerant line. You might also hear strange noises or see a spike in your electricity bill.
Turn off the fridge and unplug it. Attach the refrigerant gauge to the low-pressure valve. Open the refrigerant supply valve and monitor the pressure. Regass the fridge until the pressure reaches the recommended level.
Expect most gas ranges to last about 15 years when well-maintained.
A propane fridge can asphyxiate you if the burner is not getting enough air. Poor combustion can result in carbon monoxide poisoning. The alarming thing about carbon monoxide is that it makes you gradually tired and groggy, and eventually unable to handle the situation, leading to asphyxiation.
Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid. The liquid ammonia makes its way to the evaporator where it mixes with hydrogen gas and evaporates, producing cold temperatures inside the refrigerator's cold box.
When the gas level drops, the fridge's cooling capacity decreases, leading to inefficient cooling and potential food spoilage. Regassing your fridge involves adding the necessary amount of refrigerant gas to restore its cooling efficiency.
Leaking refrigerant: Freon leak repair costs $200 - $400. Regassing is not normally needed unless there's been a serious leak. Damaged fridge seal: Seal replacement costs $50 - $60 per part, plus labour.
While refrigerator compressors can be expensive, usually falling between $200 and $650 with an average of $375, the total pales in comparison to the several thousand dollars you'd spend on a new fridge. If your fridge is nearing the end of its life anyway, consider a full replacement.
There are several causes for a refrigerator that doesn't cool, including dirty condenser coils, poor ventilation, improper installation, faulty or dirty gasket seals, unorganized food storage, appliance location and malfunctioning internal parts.
If your fridge is not cooling but the light is on, your freezer may have an icy build-up. Unplugging your refrigerator may be a good troubleshooting move. The ice may be blocking a vent in the freezer that's preventing your refrigerator portion from properly cooling.
As your fridge slowly runs out of the refrigerant, the foodstuff inside starts freezing in the fridge part of your refrigerator. The salad leaves start to turn black, which is the first sign of frostbite. The tomatoes stocked in the vegetable tray freeze, and so do the eggs as well as the milk.
Normally, your fridge gas will last the life of the fridge, unless the pipes are physically damaged or the factory welds are faulty. However, there are also many other much more common and less expensive faults, which can also prevent your fridge from cooling.
No longer in business, Servel manufactured gas refrigerators between 1933 and 1957.
For example, overloading the fridge with too much food can put extra strain on the motor, which will cause it to work harder and potentially fail sooner. Similarly, frequently opening and closing the fridge door can also lead to premature wear and tear.
The most common cause of a propane gas refrigerator not functioning properly is due to a dirty flame. This is the product of debris getting into the burner tube. Debris such as insects, lint, hair, or dust build-up are most common.
