If there was no valve or an entry point, this will let you decide to cut the tube and fabricate it by putting now a valve on the area that you do cutting..

Jenn-Air JS48SEDBDA, sn 1271791 will not cool both freezer and refrigerator


The number reason for the Jenn Air no cool situation is caused by a break down of hte PAG oil in the compressor, thus clogging the capilary tube at the filter drier area, and causing contamination within the system. Per the Maytag TSB, a new compressor kit, heat exchanger, and new liquid line drier are required to be replaced. The compressor kit should come with a new main logic board. The ramaining componants need to be completely purged with nitrogen till clean. The condensor coil must be clean and free of any dust. A new lower freon charge follows the completed repair, and replacement decal to show new charge.

How to add Freon to a Air Conditioner or Refrigeration System


Adding Freon to an air conditioner or refrigeration system takes very specialized equipment and years of experience...it would be impossible and irresponsible of me to try to tell you how to do it through a computer.

Let me explain this further….
In small refrigeration systems such as you have in a refrigerator or a beveage cooler, the amount of freon in the system can often be measured in ounces of weight. Many times, just a few ounces. To get these charged correctly takes tons of experience and very finely tuned equipment. Just removing the hoses can release enough freon to make the difference between the system working or not working. Very sensitive scales are needed to weigh in the freon. To make sure the correct amount of freon is in the system, the system must be evacuated to a complete vacum. You need to have a special pump to do this.


To add to this, most small refrigeration systems are factory charged and sealed. They do not have access ports built into the system. To do anything to these system an access port must be correctly placed in the system for proper evacuation and charging. Then also add the the equation the fact that if you need to add freon to your system, where did the exsisting freon go? Finding and fixing very small leaks also takes sophisticated detection equipment.

The next problem is the many different types of freon that are used today. Some equipment has the type used, very clearly marked, but many do not. Only knowledge and experience can tell what type freon is in the system, and then it can be very difficult sometimes.

Air conditioning systems can be a bit more forgiving, but are getting more and more difficult to analyze and figure out exactly what is going on. The many types of refrigerant and variable speed compressors are making troubleshooting very difficult. Add temperature sensors and variable speed condenser fan motors into the mix and it becomes a nightmare.

Heat Pumps are very sensitive to either under or over charging. The only correct way to charge a heat pump is to evacuate the system and weigh in the correct charge.

Leaks in heat pumps or air conditioners are often very difficult to find, also. But finding a leak and fixing to correctly is the only way to achieve a successful repair of an air conditioning or heat pump unit.

So hopefully now you can see that refrigeration, air conditioning, and heat pump system charging is not something that can easily be done without the proper training and equipment.
Oh, and did I also mention that it is illegal to handle and repair any type of system the contains any type of refrigerant with out a refrigerant handling certification in the United States? Yes, and the although rarely anyone has been charged, it still is the law.

Please call for a certified repair technician to repair any refrigeration system and do not try to do it yourself.

How to add freon to a refrigerator by urself.


You don't need brazing skill or brazing tools to add freon to a refrigerator. And you don't need license to buy it's freon because all refrigerators now a days use R134.
First you will need a line tap which is available at most ac supply. Then you will need a retro fit adapter. available at most auto parts or where they sell automotive ac accessories. Then the freon and charging hose for R134. You would do it as if you are charging an old car with R134. Note that you should use the charging hose with the gauge. If you are handy it is a piece of cake.
One thing to remember is that refrigerators are not air conditions. So the low side pressure is much lower. As you charge it the pressure usually starts at 10psi or less then as the freezer gets colder can be as low as 5psi. Another thing is that it uses much less freon. An indication that it is overcharged is the compressor gets cold instead of getting warm. An indication that it is low on charge is that the compressor gets too hot, and the coils (condenser) do not get warm enough to dissipate heat.

What happen if my refrigerator compessor is overloaded with freon


If overcharged during charging of Freon compressor will be stressed and cooling will affected. Charging refrigerators are very sensitive to overcharging because refrigerator's use very little Freon, only about 6 ounces. Symptoms of overcharging are high compressor amperage and difficulty cooling. Best to weigh Freon while charging and always use a new filter drier. Refrigerator's are also extremely sensitive to have even one drop of room air in the lines (sealed system)before recharging and require a long and perfect vacuum before recharging. Symptoms of air in the sealed system are compressor starting and then shutting down because small amounts of room air in the system cause compressor to strain bogging compressor. Air in the system will cause water droplets to freeze in the capillary tube causing a blockage that causes the compressor to stop and start again once the droplets thaw out. I will be glad to explain more should you have more questions, Thanks, Sea Breeze
