Freon leak recharge

Video how to replace evaporator 1 door refrigerator.

Whirl Pool fridge #EL87TRRRS02 It made a loud noise then a hissing with all the freon gas coming out into the room and inside fridge. Whats wrong and is it wort fixing? It's not that old, bought new...

Try to ventilate the room. The auto defrost heater sometimes rubs the evaporation coils. When heated it can knock a hole in the evap. Today's appliances use R134a which can be purchased at any auto outlet. What ya need to do is repair the hole and then evacuate the air outa the system to keep it from forming ice inside the lines. Only 1 third of a 12 ounce can is needed to recharge the ice box. Overcharge is just as bad as undercharge.

I have a 2001 Saturn SL2. The air conditioner only blows warm/hot air. I don't know if this is related, but the car also has a leak around the radiator. It constantly needs to be filled with...

No, these problems are not related. The radiator is a sealed system and you may have a leaking hose, bad water pump or the radiator may have developed another hole in it.

The A.C problem is one of three things.

1. The A/C Freon has run out of the lines. This is a fluid used to maintain cold temperatures and produce the cold that actually comes out from your vents. It could be as easy as recharging the A/C system.

2. It could be the high pressure line that feeds the freon to the system. This would require replacing the hose and recharging the system.

3. It could be the A/C Compressor is bad and need to be replaced and the system recharged.

Each of these are progressively more expensive and should be fairly easily diagnosed, albeit by a automotive professional. I would not suggest you try to fix this yourself.

Refridgerator does not get cold, maybe needs freon charge or coooland recharge


If your refrigerator cooling doesn't seem to be working well, and you have no idea what to look for in troubleshooting your problem, there are some things you can do to try to figure out your problem without paying a serviceman to come into your home.

Most new refrigerators come with automatic defrosters. Although this is a standard feature the drain hole in the defrosting assembly can get clogged with debris, lime, or even ice. If this happens the defrost will not work and there will be a build-up of ice in your freezer that begins to block the freon from flowing properly and causing heat to react improperly and cause your refrigerator to stop cooling.

Freon systems in a refrigerator are closed systems but on occasion you may need a recharge. Refrigerators use R-134a freon, just like in an automobile. The old R-12 freon is no longer available, so if you have an older model of refrigerator you will not be able to obtain the freon, and it will be recommended that you replace that refrigerator.

The seals that are on the door of the refrigerator and freezer can dry rot with time. When you begin to see the seals cracking or warping, if your refrigerator opens more easily than before, or if you see the the door does not close fully without pushing on the door then the gaskets around the doors will need to be replaced. They are held in place by clips and the replacement is an easy fix.
Holes in Lines

Let's face it, many people find ice in their freezer or the back of their refrigerator and will try some self-help without knowledge. They will grab a knife or fork and start chipping away at the ice. This is extremely dangerous. There is a great risk of puncturing a hole in the freon lines by stabbing at the ice. Since freon has the purpose of cooling most ice collects the thickest on the inside of the walls with the freon lines right behind the plastics. A better method of removing the ice is to empty your refrigerator, turn it off and leave the door open. If you want to speed up the process you can turn on a blow dryer and aim it at the edges of the ice. If you aim at the edges you will warm up the ice and create warm water which will flow down and help to separate the ice panel from the wall.
Uneven Refrigerator

If a refrigerator is not even on the floor it may not close properly. Rock your refrigerator and see if it seems to topple from one foot to another. The feet on a refrigerator can be adjusted by screwing in or out and leveling each foot individually until they are all even.
Non-Problem Warming

If your home is hot your refrigerator will work harder. If you put a lot of food in your refrigerator and freezer, your coolant will have to work harder, and it will seem to take longer to cool. It is just that there is a lot of food that is trying to freeze or maintain cool temperatures.

Good luck and Thanks

I have a 2001 Expedition Eddie Bauer. One of the AC lines has failed and I lost the freon. How hard is it to replace just the line? What needs to come apart? Thanks

Depending on what line it is, that varies on how hard it is to replace. Being at home, unless you have a vacuum pump to remove moisture from the a/c system, the whole repair will be next to impossible. If you can replace the line, you will need to find a professional shop to evacuate and recharge your a/c system. If you recharge the system without removing moisture it will not cool well.

Ac blowing hot air

Sounds like you have a good sized leak in the system. The service man should be able to locate a leak that big. You might be able to locate it yourself. It's more than likely in the outside unit or indoor coil not in the lines that run between them. Look in the outdoor unit and look for any oily spots. The compressor has oil in it and it will show up where there is a leak. Look for any pipes that may be rubbing together as this will rub a hole in a line. Look at the indoor coil looking for the same indications. Hope this helps.

Need to jump compressor on to recharge refrigerant

You should not have to jump compressor to recharge a/c system, when adding freon low pressure switch will kick compr on, if it's not kicking on or it read low freon on your dash, replace both low pressure switch's, both sit along fire wall from left to right on a thin a/c line, when replacing these switch's make sure what ever freon in system is recover.

Need freon recharge. punctures freezer coil in

You punctured the aluminum evaporator . In the many years I've been in refrigeration , I have yet to find any way to patch a hole in the evaporator . I've used epoxy , solder , and all different advertised ways to try to patch aluminum . Nothing worked ( for long anyway ) . My suggestion would be to buy another refrig . You will be wasting time and money trying to " fix " this problem . To repair it yourself , you have to have a license to buy R12 , maybe you can buy R134A without a license , you have to look on the " modell , serial number tak to see which it uses and how much to use . Also , the system has to evacuated ( all air removed from the lines ) . Do you have a vacuum pump ? You have to buy a solder on connector ( or saddle valve which WILL leak eventually unless you get a solder on valve ) which will connect to the larger tubing on the compressor or use the access line already on the compressor but is pinched off . Do you have guages for the refrigerant type you need to use ? Once you have these things , reply back and myself or someone else will help you procede .

It's a bit more complicated than you may think. It's not good to braise a hole you need to take a 6 inch piece and splice it into the area of the hole. As for recharging if you have never done it don't attempt it. Since there was a hole you may have gotten contaminants into the line and contaminated or burnt the system. For one thing you need to be certified as it is against the law to open up a system and discharge it into the air. The old freon is poisoness to small animals and if you don't have the right equipment you can't do it anyhow. Also depending on how old the system it may take R12 or R134. It's not just a matter of pouring new freon into the system. It has to be evacuated and the old freon captured then it has to be measured then with the right equipment pushed back into the system. Like I said if you have never done it don't even try it you could make things worse.
