SOURCE: high head presure , not

There is a valve inside of most compressors that when it fails (sticks) it either fails high or low. If you have the wrong size of fan it may have overheated. You can try de-energizing the unit, then lightly tapping the compressor in various places with a rubber mallet. I know it sounds goofy but it might save you a repair bill.

My LG fridge model lfx25976sw isn't cooling. Coils are clean. Both fans working. Full of refrigerant. Feels as if the compressor is on (can feel vibrating upon touch) what's my next step?

U sure the compressor is running? Have feeling it is not - try replacing the start capacitor/relay in fridge.

And how do you know it is full of refrigerant? Did you load it with freon? If so, hope you were very exact with the charge amount since refrigerators need the exact correct amount of freon to work. That is why when they are gassed up the charge is weighed on a scale before insertion.

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 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.

I just purchased the freon can for my truck, but the can says to attached the hose into the low valve and I could only find the high pressure valve. I'm using the 134R it's that correct or should I use the...

You want to use the R-134. But you have to locate the low pressure port in order to charge it. I am not aware of its position exactly due to variations between models and years but if you follow the lines off of the compressor you should eventually run into a low pressure service port. However you do have the correct freon for the vehicle.

I need t recharge the freon. It takes R22. Where do I charge this system? I pulled the roof cap off and cannot find and caps to recharge the system

AC's routinely are sold/installed without charging valves.

So, unless your unit has been worked on/serviced in the past it will not have any place to charge with freon.

Note: unless you've developed a 'leak,' it is unlikely that you've lost any freon, and in the event that you have - it will take a Service Tech to install valves and charge your unit correctly.

I would call a Service Tech to assist.

hope this helps.

Trying to find a dual capacitor for Intertherm a/c model # s3qa-048ka

That system uses a 40+5/370 capacitor. The Intertherm part # is 620888. You can also use a 40+5/440 cap. You can pick one up at a local dealer or distributor, or order online. Look at spending about $15 for the capacitor.
