If you find a block of ice infront of the coil unit You would have to turn off the compressor and just leave on the fan to melt the ice.
This means that either the fan motor burnt out, your low on freon and need to recharge, or that coil is dirty and needs to be cleaned

Why does it work for a few hours, then shut off?

Sounds like you may have ice build up on the coil. This will cause the refrigerant pressures in the AC to go out of desired range and cause the unit to shut down. Ice build up can be caused by a dirty filter or blocked coils in the front of the AC or a fan not running up to speed. There could be another problem with the AC refrigerant charge, but normally the homeowner can not fix that. If the unit shuts down, it will not start again until the pressures equalize.

My unit wasnt working right so i took the front cover off and it is covered in ice.

Two things generally cause this problem. High outside humidity and a clogged air in take filter. Allow the unit to thaw completely, remove the air intake filter and clean it. Allow the filter to completely dry, before reinstalling. Never operate the AC unit without the filter in place.In addition. the unit may not have enough downward tilt at the rear. Generally 1/4" to 1/2" is required. so water will flow to the rear of the unit to the drain hole.

Hope this helps and thanks for choosing FixYa.

I have purchase samsung Ac from Rathna Fanhouse -Chennai -

Assuming the ice is on the front of the unit it's a good bet that your inlet filter is dirty/clogged and is restricting the air over your evaporator coil. The first thing you need to do is turn off the unit and let the ice melt; in other words - 'defrost the AC.'

I would then try cleaning the filter (usually just needs to be washed out) but I'm betting you will need to clean the evaporator coil too.

Cleaning the evap coil is not that difficult, sometimes it can be as easy as pulling a 'sheet' of matted hair/wet dirt from the front of the evap coil.

Often you will need to use a brush of some sort and clean the coil. The object is to get the evap coil clear of all dirt so that air can flow easily through the coil.

good luck!

Icing up of unit

When you clean the Ac unit, Make sure to take the Unit completly out and clean both the condensor coil as well as the Evaporator coil.
If you are able to run the unit with it out of the window. See if there are any service ports connected to the unit (Guage hook ups), or any OIL spots where is looks dark, (Checking to see) if its leaking.

Wasnt sure how you cleaned the unit, So just make sure both coils are cleaned well with water, and make sure to avoid getting to much water into the Electronics.
Good Luck!

Water doens't drain properly and sitting there,

that's fairly common for window units, it's ok to drill a small hole in the underside of the case to drain the water, just be sure you don't puncture the condenser in the process.

Wall ac unit keeps freezing up inside.

Do not run it on maximum cool and fan on low. Freezes up all the time this way.

I just turned on my ac for the first time this year. I found leaking on my carpet. I had to change my filter and found ice on my pipes. also the area around the unit was damp. Did i fix the problem by...

The ice buildup comes from low refrigerant or poor airflow.
Is your indoor fan runnig OK?
Are your evaporator coils clean of dust and dirt?
If fan is good and coils are clean, call a service tech to check your refrigerant charge.

Turn it off. Remove the filter . Clean the filter. When filter is out look to see if there is ice behind where the filter was. If so, let it melt. With the filter removed you should be able to at least see a little of the drain pan...which could be blocked up.If blocked, unblock it. When done, place filter back in unit, turn on, observe.

I'm assuming it is a window unit and not central air.

I hope you don't need anyone to tell you that it can't be pitched towards the inside of the house ;)

that would do it too.

Ice on the coil fins of my Window AC unit......

set your unit to fan mode only, to thaw the ice, after the ice melts, look at your evaporator coil, see if its dirty, if its dirty, then you might just need a good cleaning. if the coil is clean, look at your thermostat setting. it should not be all the way cold. the compressor would run continously and it would freeze the coil. third, the refrigerant system could be partially clogged up or it lacks refrigerant. these problems initiate freezing of the coil.

Ac ices over

First you need to make sure the filter is clean to allow good air flow through the evaporator. If the filter is clean make sure the evaporator is not plugged up with dust and lint. If all that is ok your problem is the a/c BTU's is to big for the size room you have the a/c in and it is getting the room too cold. If that happens the evaporator will ice up and will not cool the room.
