We've had this unit for several years without a single proble and now, suddenly, it only blows warm air. I figure it needs Freon but have no idea how to do that and can't get any appliance repair person to even take a look at it.
Shad roof leaked water on my unit The window air condisner will not work there was water in the plug in and I am not sure if the water is in the front section of condition Please help with this problem would changing the plug be the answer I am looking for?

Re: Samsung window air conditioner
Freon or R13 is no longer allowed to be used in air conditioners because it attacks the ozone layer when it escapes.
There are heavy fines for intentional release into the atmosphere.
If an engineer was to replace the gas with a legal refrigerant then he would want to collect and flush any remaining gas for safe disposal and change the rubber seals in the pump etc. Apparently the new gas will attack the old type seals.
I was going to get the aircon recharged in my Mazda RX7 but it would have cost about £300 because it had the old gas but then we had a rubbish summer so I didn't bother.
It all seems like a money making excercise especially considering the huge amounts released before 'Green Fever' swept the world.
There is however a 'drop in replacement gas' which is compatible with the old seals and remaining nasty gas. It usually contains a leak stopper and flourescent dye to help find where any leaks remain.
Try typing DROP IN REPLACEMENT FOR R12 REFRIGERANT in a search engine or a popular internet auction site.
You can then recharge your own aircon for a fraction of the price after a bit of study.

Hope you have fixed this by now. Look up internet articles about a diagnostic sequence for your climate control. On some of the units a sequence of button pressing will generate a exam. It could be a ductwork door is not working to allow chilled air into the cabin.
Remember several things. The pressure reading of 30 may not be Freon but contaminated air and Freon. 30 is a measure of pressure or volume but not purity. Then depending if the system is clogged, the high pressure cut off switch that is measured on the high pressure hose may be cutting out the freon flow.
Only a qualified service technician can tell you if the unit needs to be recharged, by testing in the input and output pressure. It would be a good idea to have it serviced professionally, since it's never been serviced. It could be money, well spent. Or it could be a Long Hot Summer without the AC.
could be several things...if all is working/blowing and its clean inside & outside with a clean filter then more then likely it's low on gas/freon......if you continoue to run it it'll pobly ice up/freeze......also make sure you hear the compressor running as well as the fan blowing. sometimes this can be tough listen for that deep rumble/humming sound thats the compressor.
Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.
yes, you can check for freon: you can force the compressor on using 2 jumper wires. look for the wires leading to the compressor motor. Disconnect these wires from the source (not at the compressor). Using jumper wires, connect external house power (120 VAC) directly to compressor and turn that power on. The motor should start. If the copper lines (or finned radiator) get cold, then your freon is ok.
There is usually not a fuse in these units.
