popular. 水管裂了 could be from several light freezing cycle or one very

soldered very well, after years it seperate. The 10K damage mostly caused by
water not to replace the pipe. You can install warning sensor everywhere if
you are concerned, that way you know there is a leak and can shut off the
main right away. Another thing you can do is to slowly re |

发帖数: 4125 | 2 I don't think it is better, but it is easy to do with home owner with almost
no tools. Just a cutter is all you need. It is much harder to learn to
solder copper pipes and takes much more time. |

发帖数: 4125 | 3 Leaking at the copper tubing is bad soldering job, which can be easily fixed
, the actual coil leaking is bad and should be replaced (as it is very hard
to repair the coil itself)
I think copper tubing will always be used (even with new coil) and there is
nothing wrong with it. |

发帖数: 4125 | 4 What? don't even take me 3 hours to clean the evaporator coil. That is
vacuum/recover all the Freon first, remove the coil, take it outside, hose
it wet, spray coil cleaner, wait, rinse for a long time, put it back,
connect/solder the pipes back, put the freon back.
Unless the new coil does not fit and he need to do some duct work to fit. |

发帖数: 4125 | 8 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.

red ceder or hardwood shingles.
Metal roofing made from galvanised steel in sheets of strips are much
cheaper, they have many patterns and color choices avail to mimic other roof
material. They also install very faster.
I prefer mechanically seamed metal with concealed fasteners contains sealant
in seams than flat-seam metal with soldered seams. |

发帖数: 160 | 24 Google should tell you. Anyway, it should be the control board problem.
There is a fuse which is a fixture on the board for the old version, e.g.the
one I bought in 2010 or 2011.
If you have the new version you just need replace the fuse; for the old one,
you can replace the fuse if you have a solder or just call the customer
service. They will send you a new board free of charge. I just got mine a
couple months ago.

呵呵，我最关心的是下面“两句话”，其它都是废话。一再的提醒大家就是要找成熟的
师傅。一个成熟的师傅如果这么简单的案例都搞不定，那还玩啥空调。
我曾经也有说到，铜管coil,许多机会都可以修的，不需要全换，这个师傅还是蛮有职
业道德的，不过这文章发表在充满着商业广告的NEWS 网站上，形象还是要的。
在空调帖，在班上，遇到coil漏，大都是换掉，真正修理补好的能有几个？当然相信有
的必须要换，不过我亦相信50%的可能都修得好。这不能怪我们的同学，只能说师傅的
素质。
“He removed the cover from the side of the coil and found that a hole was
rubbed in the suction line. ”
“When the refrigerant was removed, he patched the leak using silver solder
and repositioned the piping so that it would not rub again.” |

发帖数: 469 | 26 Even if you wanted to or could repair a leaky coil, we have 2 reasons not to:
1. if there's one leak developed at one spot on the coil, there will be more
leaks appearing at other spots on the same coil very soon after you repair
the first leak. The material and workmanship of the coil manufacturing and
the harsh environment that the coil is subjected to remain the same for the
entire coil;
2. In order to either replace or repair the coil, almost the same steps have
to be taken by a service tech... 阅读全帖 |

发帖数: 1308 | 36 1. 机器并没有带AC plug，就光秃秃三个线头，给了三个wire cap。我现在弄到一个ac
plug连一根够长的线，strip出来了三个裸线。能直接用wire cap把相应的线连起来么
？我看有人说这样不安全，想问问看。我能想到最可靠的办法是把线solder在一起，加
heat shrink和electric tape，会不会overkill了。
2. 另外看那个manual, 说是如果橱柜本身是frame的，让加两块wood block在mounting
position. 这连块木头需要钉或者粘在橱柜底板么，否则它能起什么作用阿（wood
screw穿过木头和底板，不是相当于底板需要承受的拉力还多了这个额外的木头重量？）
3. 上那四个木螺丝，manaul上说先不上紧，挂上橱柜调整好位置再锁紧。挂上橱柜之
后木螺丝的头就在那四个keyhole里面了，只剩下一小节螺丝杆露出来，然后这怎么去
上紧阿？

measured it, it is blown, and it is soldered on.
I emailed their customer support, didn't expect any response, and was
getting ready to remove the fuse and repair the board myself. They actually
replied within a couple of minutes and said they'll ship a board to me today
free of charge, and the new board will have a replaceable fuse.
Excellent customer support, that was a nice surprise. |

发帖数: 133 | 49 这个可以没有。想想在2000摄氏度（propane）火焰下，怎么会流出来等你擦。另外
flux不用太多，薄薄一层就行，均匀是关键。还有，管和套之间要很轻松咬合，不要太
紧，要留一些空间给solder。
友情提示，焊之前要准备一只灭火器，同时在旁边放一大桶水，以防万一。如果枪口方
向有木头或者其他易燃材料，一定要用阻燃布挡一下。或者你有剩余的cement board，
钉一块。安全第一。 |

发帖数: 437 | 50 这个最好还是不要自己弄，如果不是专业，或者动手能力特强，工具齐全的话。这个管
路的焊接叫brazing，比soldering要结实很多，温度也高很多，要有高温火焰才行。抽
