I have looked an took apart a few things to check it out..compressor runs ..an outside fan in back runs ( evap fan doesnt run) compressor is alittle warm really quite runs nice....the evap is not getting cool or cold i unhook evap fan is out..help me to fix this myself..thankss
Our LG refrigerator wasn't cooling either. With ours it turned out to be that the light wasn't turning off when the door was closed! It seemed unbelievable at first, but the heat from the light bulbs was heating the whole refrigerator section to just about the same temp as the outside room. Here's the key, 'though. If this is the case, the fridge section is warm, but the freezer is cold.

If compressor is running check and make sure your cond. fan and evap fan are running. Also check in freezer and make sure evap. coil is not covered in ice. Also clean your condenser coil. You could be low on refrigerant. There are quite a few things to check.
There may be a manual reset high limit... look for a red button on a round part hooked to the small copper line and push it in hard...
Also the compressor may have kicked the overload and needs a few hours to cool and it reset, that is interanl insdie the compressor.
Contactor may also have went bad...

With out looking at it, I can give you some ideas that could cause these problems. I need to know where the water is coming from? If it is leaking on the inside, this narrows it down some. It sounds to me that the evap. coil is icing up which the unit could be low on freon, you're indoor fan motor may not be running up to speed, a dirty filter or evap. coil. You need to shut the unit off, maybe through the night. Get a latter and remove the cover on the indoor unit. Check and wash the foam filter and look the coil over for excess dirt build up. Leave the cover off for now, and go outside to the outdoor unit. Have someone turn the t-stat to on. Watch and make sure that the outdoor fan stays on and listen very close to see if you can hear the compressor running. It sounds to me that one of the named items I have listed is causing the evap. coil indoors to ice up and blocking the air flow to you're home. Let it run with the cover off and just watch it for a few hours. If it starts to ice up and the filter is removed with cover, and the indoor fan is also blowing air, more than likely, you have a small freon leak which is causing the problem. If I were there, I would know in a few min. what the problem is. As far as the leak, it is the ice melting off and running over and the condesate line may have a partial plug in it. If it is low on freon, you can go outside and put your hand on the larger copper line to see if it is warm. It should be sweating or condesating if it is charged properly. If warm or barely cool, more than likely it needs a charge and leak check.
You will need to have your door gasket seals inspected and possibly replaced.
Then you might want to check behind the back cover of your freezer and look for ice build up and excess frost on your evap coils - this indicates seld defrosting problems - and the symptoms are functioning compressor and evap fan but air is not cool enough - Once you manually defrost those with a dryer and let your unit cool for a few hours, if it comes back to normal you know you have a defrost problem and will need to have your control board / defrost components checked.
Also - you might want to have them check your damper system it might be shut or not opening to let the air from your freezer in your refrigerator. (if applicable)
The evap fan is running - but is your compressor motor running -t his is what i'm concerned about - 82F ? That is very high - this suggests to me there is no cooling AT ALL - only the fans are working - and my gut tells me your compressor is not running AT ALL - I would rule out thermostat since when it kicks in and your evap fans turn on, your compressor should turn on too. If this fridge has electronic controls, have your motherboard / control boards checked, have your compressor checked. If your compressor is running and you can hear its distinctive humming sound, then you have a sealed system problem, a major one :) Have those two things checked.
Reasons for icing up are dirty filters,dirty indoor evap coil or low on refrigerant. Check these. Your compressor is probably overheated. Let it go for a couple of hours if you are in a hurry. Run a water hose over it. Rus
If this is a Bev-Air, don't think the door switch will control the fan. At the evap, there is a temp sensor called a fan delay. When unit goes into defrost mode, this warms up. Some also serve a dual purpose. It will terminate the defrost cycle at a certain temp., say 51 degrees or so, at the evap. Anyway, when unit comes out of defrost, it keeps the fan off so it allows the evap to cool quicker and to prevent circulating warm air. This could be your problem. Not a hard fix but they can be a pain sometimes. Outside chance that the unit is low on refrigerant (freon). This will not let the evap get cold enough to trip the sensor back into position to turn the fan on. Good Luck. Restaurant Parts and More carry alot of Bev-Air stuff. 1-888-814-1110. Ask for Rick
First, please re-check to see if both fans are running, the condenser fan by the compressor and the evap fan in the freezer. Next, empty the freezer and remove the evap cover. look at the evap coils. Are they completly frosted up -- if so, you have a defrost problem - this will cause the condition you describe- IF they are not frosted, are only a few of the passes of coil frosted and some just wet with no frost? Then that means you need some freon. The fact that you have some cooling means that the compressor is probabaly OK.
