How to charge a freezer with freon

If it is not fixe you will be constantly spending money needlessly. It should NEVER need to be recharged unless there was a leak in the system. Before a unit can be recharge you should always locate and repair the leak. The gasket on your door is very.

How to recharge a freezer and how a freezer works.

You would then read the model tag to verify what refrigerant is in Your freezer and the charge in ounces. The easiest way to clean out the system is to apply a sweep charge which is of the recommended final charge on the tag and allow the unit to run for minutes,. You can add Freon to a chest freezer by opening the chest freezer and pouring in the container of Freon very slowly.

Be very careful not to burn yourself. I don not know if that answer is genuinely ignorant, mischievous or sarcastic, but it is extraordinarily stupid. Freezer Freon Recharge 134a.

How To Install Bullet Piercing Valves To Charge Refrigerators Or Air Conditioners Low On.

The tag will state the refrigerant type and the amount of refrigerant , as measured in weight with which the manufacturer charged the system. Unsubscribe from Dan Webster? Mad Electron Engineering 19views. How to Recharge Freon to Repair a Refrigerator.

Only EPA certified technicians can buy R-12. Both refrigerators and automobiles use R-134a as a refrigerant , and adults can buy it at most automobile parts stores. Combining the noncompatible refrigerants R-and R134a will lock up the compressor. Most evaporator systems use capillary tube systems to manage the flow of refrigerant into the refrigerator. They require a very precise refrigerant charge to work at maximum efficiency.

Too much or too little refrigerant will result in a system that will have some cooling effect, but will not be working to its full potential. 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. Depending on the type of compressor, I charge liquid into the suction line. With refrigerant cooled compressors, it takes a heck of a lot of liquid to cause any damage.

You have to monitor the charging , but you should be anyway.

Charging vapor in quantities much over a pound or two is a huge waste of time. While most new fridge- freezer models do not use Freon as a coolant, older refrigerators often do. SOURCE: need to add freon if you are tapping into a sealed system, then you use the larger of the two copper lines coming out of the side of the compressor (this is the low pressure line, the compressor pulls from this side). To add refrigerant to a refrigerator, you will need to braze in an access valve.

Those are a T type valve that go into the LOW side of the compressor on the suction side. Once you have that valve brazed in you can then add the refrigerant. I only work on one old pos freezer.

When charging in the summer we go till the glass is clear and then add pound per hp. Dont know if thats proper but its how I was taught. The last step in replacing the Freon in your refrigerator is to add a few tablespoons of PAG oil.

This oil helps lubricate the compressor, which allows the refrigerant to easily pass through the system. Refer to the manual to determine the exact amount of oil required for your model. Typically, you’ll add about five tablespoons. Hold the can upright (most blended coolants need to charge with the can upside down, in its liquid state.

This requires a different charging method.) and open the valve on your gauge. Let the coolant flow for about seconds then turn off the valve at the gauge, check you pressure. Remember we are looking for 3-lbs. Re: What should be my pressure on a 404a freezer. Usually depends on the temp of the conditioned space.

So look for a low side pressure of about 25. High side is ambient plus 30. A degree ambient, for example, add and get 1degrees. If the freezer system has been open it must be put in vac. Then with interior coil exposed put in a few oz and start compressor.

So it is impossible to connect the refill can to the high side with the refill kit you buy at the auto store. You could put the can in a bucket of warm water whole filling that will help get all of the refrigerant out of it. I realize there are other reasons than low refrigerant that can cause this, but want to give it a shot before buying a new one. We bought this one used and it has ran well for four years, but recently stopped freezing on the lower shelves.

All ( 5) The charge amount is decided by the refrigerant vapor and liquid ratio in components and the internal volumes of each components including the evaporator and condenser coils, filter internal voi liquid pipe volume, and compressor lubricant oil type. Proper charging is key to a product running safety and performance. If this is your first visit, be sure to check out the FAQ by clicking the link above.

Nobody would do it for the freon. Your best bet would be to sell the freezer since it works and buy the metal garbage cans with the proceeds. Many people might be suspicious of the old wiring though, but hey, go for it. Generally you charge a refrigeration system by weight, not by pressure or temperature.

Say, for example, if you were adding refrigerant to a system, you might add a pound of r … efrigerant. Compressors have rubber seals that can leak overtime allowing the freon to escape and Evaporators and Condensers have welds and fittings that can also leak.
