I sent it in for repairs a few years back, but now it is failing with the exactly the same symptoms: compressor working non-stop, temperature never goes to C it has a digital displaybut stays around C.

It has developed this condition very gradually. My freezer has two screw-on connections I think they were added during the repairs : one on the stump pipe going out of the compressor bottomand the other on the little stump going out of filter-drier top :. My freezer uses just g 4.

I know this is not really a fix without fixing the leak, if it helps for just a few months, I'm good with that. The high pressure side should have a different fitting. This is how cars are anyway. So it is impossible to connect the refill can to the high side with the refill kit you buy at the auto store. The small cans don't have enough pressure to overfill the system. So you can't overfill it. You could put the can in a bucket of warm water whole filling that will help get all of the refrigerant out of it.

Freezers and refrigerators actually use very little refrigerant, and it's important not to overfill them. I found the low pressure tap, and it was in psi vaccuum while compressor is running, which confirmed what are all the seeds for minecraft pe for me that the freezer didn't have enough refrigerant. I slowly added refrigerant till the low side was around psi.

It took surprisingly little gas, and the can is still nearly full. The freezer went to C within an hour, so it obviously worked. The low psi line is larger of the two. Your schrader valves may be leakingi. Replace valves before you re-fill it. I don't think the auto and refridgerators are the same size fittings, not sure.

Filled the low pressure side pipe the larger of the two by first installing a tap or bullet piercing valve:. Then attach the hose end with the piercing needle to a oz Ra refrigerant freon. Follow the how to use the t fal actifry valve instructions carefully as you don't want any air going how to recharge a refrigerator the system.

You may have to bleed the hose a little by letting some freon through - you will know as it will be a fog squeaking out of the hose. Then tighten the hose fitting. Then just be patient. Run the fridge back on. The whole process may take an hour or two. When you see the needle about green zone then you are done my friend. Good Luck! Automotive refrigerant Ra has and additive that should NOT be used in refrigerators or freezers.

Most refrigerators use around 4. This is crucial and must be accurate. You can not be accurate when using a can. There are laws in place for many reasons.

Tester could you elaborate what could go wrong? Except that I'll need to refill again as I didn't fix the root cause of the issue?

My advice when it comes to working with refrigerants: If you don't know what you're doing, you shouldn't be doing it.

Thanks for answering! So which one is the high side and which one is the low side? My freezer has exactly the same connections on both pipes.

If they put the same fitting on both sides then you would have to connect a set of refrigeration gauges to the fittings to determine which is high or low.

Usually the low side has a big fat quick disconnect fitting on it. From you picture the one on the top looks larger to me. But then I can't really see it that well. Take the black plastic caps off and see if they are the same. Those little cans can overfil a refer as you don't know how much Freon is still in the system.

The stub is usually on the low side and a small fridge takes less than 6 psi using r — Ed Beal Jul 13 '18 at Answering the second part of my question: Freezers and refrigerators how to do a smiley face on word use very little refrigerant, and it's important not to overfill them.

DarkEnergy DarkEnergy 1 1 1 bronze badge. LadyTech LadyTech 44 1 1 bronze badge. I asked this question 4 years ago. After I got some answers I "topped up" the freezer using Ra and using the pressure gauge. In these 4 years, I needed to top it up once again, and after 2 long-distance moves the freezer is still going strong.

I believe your answer is not helpful, and is just spreading fear and misinformation: it's not against the law, and not particularly dangerous either. The Overflow Blog. Stack Overflow badges explained. Featured on Meta. Stack Overflow for Teams is now free for up to 50 users, forever.

Feb 21,  · This setup can be used to recharge any system with a Danfoss compressor. 2 The fridge is recharged via a valve mounted at the end of a short stub on the suction side, clearly identified by the green shrink-fit tubing. It’s a Schrader valve, like those used on common bicycle tires. How to Add Freon to Your Refrigerator: in todays video we are taking a look at how to add Freon to a refrigerator. Always remember to consult with your refrigerator technician, in this video a certified licensed specialist worked on the fridge. Video is made always for learning and educ. The average time to evacuate, inspect and refill a refrigerator freon system is about 20 minutes and the cost in parts would be about $20 but expect to pay a good amount of money for the service call. Note. Before you make repairs yourself you should understand whether or not you will need a technician to refill your freon system.

Click to see full answer Keeping this in consideration, can a refrigerator be recharged with Freon? We do not recommend attempting to recharge the Freon in your refrigerator yourself. An insufficient supply of Freon indicates that there is a leak in the system. We can find and repair the leak and safely recharge the system with Freon. Also Know, how much freon does a refrigerator hold? Refrigerant Charge This amount is normally found on the model plate or manufacturer's label, and it is measured in grams or ounces.

The amount ranges from less than 1 ounce in small refrigerators to more than 6 ounces, or from The main danger with too much refrigerant inside an air conditioner is that it can damage to the compressor. The excess refrigerant will collect inside the compressor and lead to subcooling, temperatures below normal. The extra refrigerant can also flood the compressor and damage its mechanical components.

Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely models with coils on the back won't have a fan. To do this, unplug the fridge and pull it out. Plug in the fridge and make sure the fan runs when the compressor is running. Locate the refrigerator's condenser and place your hand next to it to sense heat. If the condenser feels cold and the refrigerator has been running, there may be a lack or absence of Freon. The problem may also be due to a defective condenser or clogged system.

Condenser coils are located on the back of the fridge or across the bottom. These coils cool and condense the refrigerant. When the coils are clogged with dirt and dust, they can't efficiently release heat. However, R damaged the ozone layer, causing governments to issue a ban on its use in new refrigerators and air-conditioning systems in The less harmful replacement for R, Ra tetrafluoroethane , has been in common use since , but R is still found in many old systems today.

Warm food or a defrosting freezer are the obvious signs a refrigerator is malfunctioning. Check for power lights on the water or ice dispenser, if the refrigerator is so equipped. Open the doors and check for lights inside. Listen for sounds of the fan running. Freon usually travels through closed copper coils in an AC unit, but these coils can crack and result in an AC coolant leak.

A freon leak will produce a smell between sweet and chloroform. Can you use RA for a car in a refrigerator? Ra, if manufactured to prescribed tolerances, is applicable to both systems. Usually if your refrigerator needs refrigerant added, the leak has probably allowed moisture into the system. In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant. High discharge temp. High subcooling in the condenser. High pressures in the condenser. Higher condenser splits.

Normal-to-high evaporator pressures. Normal superheats. High compression ratio. The most obvious sign of an overcharged AC system is poor cooling. Compressor Noise. The compressor might make excessive noise, the sound of it struggling to shove liquid coolant through a tiny nozzle designed for gas molecules. High Pressure Readings.

Struggling Engine. Broken Compressor. Refrigerant is not consumed or used up in normal day-to-day operations, but some cars due exhibit a slight loss over time. While some will argue that on the molecular level no system is completely sealed, when your vehicle leaves the factory, its air conditioning is essentially leak free. Although an air conditioner can still function at lessened cooling power after it loses refrigerant , it will start to sustain serious damage that will eventually lead to larger repair needs and possibly a full system breakdown.

Loss of refrigerant will also threaten to damage the compressor , leading to it overheating. If leak cannot be found they will re charge the system with freon and dye. If compressor then comes on and works you are good to go. If compressor does not come on they will re claim thier freon and charge you little or nothing for doing the check.

That is unless you ask them to trouble shoot and fix the problem. If the subcooling is too high, the system will be overcharged, reducing performance, efficiency, and ultimately damaging compressor valves and start components.

The recommended pressure for a home refrigerator using RA refrigerant is between 2 psig and psig. Readings that are higher or lower indicate an overcharged system. Although the low side pressure should be around 2 psig, at times it can fluctuate from 0 to -3 psig. Modern refrigerators usually use a refrigerant called HFCa 1,1,1,2-Tetrafluoroethane , which does not deplete the ozone layer, instead of Freon.

Newer refrigerants are being used instead. The main refrigerant now used is Ra, or isobutane which has a smaller effect on the atmosphere if released. How many ounces are in a pound? It's a simple question, the answer, of course, is How much does it cost to refill freon in refrigerator?
