article in this thread (do not post follow up there, thank you)
Your evaporator coil is frozen, usually caused by a lack of refrigerant, due
to a refrigerant leak or leaking.
Turn off AC, leave the fan running to melt the ice.
Call someone to find the leak, fix and charge refrigerant to spec.
Some leak can not be fixed, you need to get a new unit.

I have an A/C problem.
1) 户外 Fan works, but no 热风。户内 fanworks, but no cold 风
2) Compressor seems not working. It seems it works at the start but will not
work later on. when i just start the A/C，the thin line is slightly warm
and thick line is slightly cold . but after few min, no cold or warm feel
from both lines.
3) indoor 出风口 temp is around 79 while room temp is 82F.
4) check Capacitor by eyes, no obvious overburn or damage, 上段和四周没有鼓
起或烧的迹象。
5) the whole set was installed in 2006.

发帖数: 4125 | 3 There is something wrong with your compressor, since it is installed in 2006
, most company offer at least 5 year warranty, you can call them to see if
it is covered, have your model number and serial number ready when call.
If it is outside warranty period, I can help you trouble shoot here.

almost gone, you have a leak some where would be my guess.
Good luck to you.

发帖数: 113 | 6 你好啊。我们家的空调的风扇老是不能自动停下来怎么回事？空调倒是能够停下来。这
样的话很不方便，每次只能用电源面板开关空调。如果要是不关，空调一直转又特别冷
。谢谢。 | b*********k
发帖数: 335 | 7 so you do not think it is compressor but leakage?

发帖数: 4125 | 8 Do you mean 电源面板 = thermostat?
On most simple thermostat, there is a fan on and auto setting, make sure
that is set to auto.
There should also be a ac , off and heat setting.
You have the temperature setting.
I do not fully understand your question, if your AC can stop automatically
to the set temperature, even if the fan continue to run, it is only moving
air around, it will not continue to cool.
1. You said 空调倒是能够停下来 but 风扇老是不能自动停下来
2. You said again 空调一直转又特别冷
Which is the case? 1 or 2?

发帖数: 749 | 9 Unless your system is completely leaked out, the compressor should run at
least for short term until the low pressure protector kicks in.
In your case, you need to do following,
1. set the thermostat to cooling auto mode and the lowest temp.
2. then go outside touch the two copper tubings which connected to your
indoor unit. Once the outdoor fan start to run, the bigger tube should be
cold, and smaller one should be warm/hot. If you don't feel them from the
beginning, then your compressor, or mo

发帖数: 335 | 10 thanks.
It does start at the beginning and I do feel
one tubing is warm and the other is (slightly) cold. but it won't last long.
what do you think the cause?

发帖数: 4125 | 11 It is hard to believe a 4 year old compressor could leak (possible, but not
very likely).
I would guess your outdoor condenser coil could have a small leak if someone
bump into it by accident (kids on a bike, maybe). Your indoor evaporator coil could leak due to formicary corrosion. Of couse, it could leak any where along the lines, most likely a bad soldering job.
Leak in coil itself is very difficult to repair, so you might get new coil,
leak in line can be easily fixed.

发帖数: 113 | 13 谢谢回答。thermostat上面是有on/auto的设置，我们放在auto但是他还是一直转。所
以现在我们要开空调只能用circuit breaker。
因为我们一般白天不在家，晚上才开空调，所以一旦空调启动，就半天不停，然后再有
风就特别凉。你能帮我们参谋参谋是什么的问题吗？
