标 题: 求教,家里GAS FURNACE炉子坏了
发信站: BBS 未名空间站 (Sun Nov 2 09:10:39 2014, 美东)
正在打电话找人修,angie list打电话找了俩个,周末都没人接,还在找,大家帮我分
析分析,谢谢
CODE说
a. pressure switch open or
b. blocked inlet/exhuast vent or
c. condensate line blocked, or
d. pressure switch closed to activation of combustion air inducer.
我怀疑B和C,
B:当初用长铁丝从室外的inlet/exhuast vent两根管子里掏出不少稻草,还有鸟毛,
鸟做窝了?肯定没掏清,铁丝太短
C:见我另一个帖子,后来我也没管

t*****b 发帖数: 157 | 5 The manual is for multi-models (brand: Trane? from American Standard inc),so
it's not for sure. The manual also mentioned after showing the air filter
inside:
"Air filters may also be located outside of the furnace using a remote
filter grille. the filter grille could be in a hallway, wall or in the
ceiling."
I have filters in wall and ceiling, and did not find the opens for Air
filter around the units, so I'm confused. But in most case, people are

g*****9 发帖数: 4125 | 24 Oh, that is very easy, you have two choices.
First, use passive sound proofing method such as glue a lot of acoustic foam
on the wall and door of your furnace room, put in duct silencer, line the
inside of duct with liner. Most cheap homes are built with raw sheet metal
which actually radiates sound. Duct liner installed on the inside of the
duct will help a lot. You can google acoustic foam (make sure you get the
one that is treated with fire retardants); duck silencer; duct liner.

f********l 发帖数: 1473 | 25 可以upgrade to the low noise furnace, 并把它升到ceiling上面。 |

g*****9 发帖数: 4125 | 26 What brand and size (BTU) of your furnace, does that include a new blower,
duct work? what exactly are you getting for parts and labor?
We are talking about FAG not heat pump, just want to make sure, right?
tax |

g*****9 发帖数: 4125 | 27 It is a ok price (not good deal) for good new furnace (such as Trane XC95M

h********d 发帖数: 364 | 28 Just checked :)
the brand is Amana, and the size is 70k BTU (my current furnace is 80k BTU.
The technician says this one is only 70k BTU since it's more efficient).
Is this a good brand with good feature and reputation?
brand. |
|
m***y 发帖数: 14763 | 29 The price quote's OK. You can always wait for a better deal, like buying a
car, but it's about this range.
Furnaces are rated by input BTU, so, if the newer one is more efficient, you
can use a smaller size.

h*******n 发帖数: 8906 | 30 last month we had the sensor changed for around $250. looks like a
reasonable price.
for a new energy efficient furnace,u can now claim up to $800 cash rebate
through a new federal program starts just this year.and another several
hundred from similar programs run by state and local utility companies.it
might be a fairly great deal if u live in a heavily subsidized state like CA

l********k 发帖数: 393 | 31 其实furnace 工作正常, 我就是不想用它。 是用gas的,应该是电驱动的。 不用的时
候有电流的声音, 电流的声音很大,很讨厌这个。谁有经验把这个电掐断。 |
|
g*****9 发帖数: 4125 | 32 That depends, good quality stuff last a lot longer.
You must have small roof, $3000 is not bad, but will not last very long,
cheap asphalt will last 10 to 15 years, good slate roof could last well over
200 years.
,waterheater($900),
How big the the waterheater? Usually they are much cheaper for 40 ga.
gas furnace($2500),
Your heat exchange is cracked, get a new one, there is tax credit if buy one
that is 95 AFUE or above.
AC outdoor($2500)都没
Depending on your size (ton), this is not bad if incl |

s**********d 发帖数: 36899 | 34
一般heater就是gas furnace。
也有别的,heat pump跟AC是一体,或者oil burner之类。 |
|
g*****9 发帖数: 4125 | 35 Yes, it know what you are talking about, there is no such thing as "A Dual Fuel Heat Pump" It should be called "A heat pump with backup furnace"(as opposed to an air handler with heat strip backup).
I can not think of one situation where this kind of hybrid setup could be useful (or make financial sense). Guess it would depend on your local unit price for gas and electricity.
I think you will much better off getting either a ground source heat pump (vertical loop) or a pure gas setup. (if gas is |

|
o*****e 发帖数: 871 | 37 回复的很专业。补充几点:
1. 观察一下furnace停转的时候,温控计是否call for heat。一般新的温控计在面板
上会显示这个;可以把设定温度调到90度,强行call for heat. 如果是,说明温控计
没问题。(具体还要测试W and C之间是否有24伏电压)
2. 一般limit switch 出故障,控制电路板会自动尝试几次点火,如果全部fail,控制
板会lock out.
3. 一般公司的limit switch 是不可调节的,不存在设置问题。
4. 关于2, 如果出气,回气的隔栅堵塞, 风机会自动用最大功率输出风量,如果电机
本身的温度超过一定预设置, 风机就会停转(因为风机内有thermal protective
switch),直到温度降到一定程度,控制板会自动重新点火。
5. 也可能是gas valve关闭或堵塞,这样控制板无法检测到点火,反复尝试。 |

w*****w 发帖数: 884 | 38 要把通到furnace的气和电都关掉呀?刚买房子,什么都不懂,初级问题请给指点一下
。还有我们家的thermostat,在heat和off状态似乎都一样,在off的时候还会加热,室
温时间什么的也都显示在那儿,不知道能不能修一下呢? |
|
f********r 发帖数: 904 | 39 主要参考静噪音/风量,我以前买一样的furnace,才800多,但是噪音大/风量也很足,
用在办公室/商业就无所谓,但要用在家里宁愿选个低噪音/柔和风的那种,还要看你放
在哪,要是远离卧室也可以。芝加哥有很多这些代理商,可以多找几家。 |
|
|
n********y 发帖数: 48 | 41 原先的系统都是20年的了,换了新的之后感觉制冷好了无数倍,另外furnace的噪音也
小了很多, 感觉家里安静多了。
但是现在还有个小问题, 地下室的refrigerant line震动的比较厉害,而且还有挺大
的声音。正好family room在上边, 所以也能听到点嗡嗡的声音。虽然不是很大,但是
也挺心烦的。
refrigerant line的声音应该是通过compressor传来的,不知道用什么办法能减低点噪
音。 |

f*****l 发帖数: 1703 | 43 昨天长周末回来,发现车库里oil furnace的烟囱烧的时候烟是黑的,technician 得过几
天才来,我是不是必须洗澡都不能开热水,烟是往外的,所以没有中毒的问题.
用几天对burner会不会有损伤? |
|
u*******o 发帖数: 405 | 44 我的furnace是Trane的XL80,有四个burner。最右边的burner旁边是一个Silicon
Nitride Hot Surface Ignitor。但是它只能管右边的三个burner。最左边的burner旁
边有一个L形的貌似ignitor的东西,只有一根火线接在上面。
现在我最左边的这个burner经常会点不着,偶尔点着貌似也是右边的带起来的。我把那
个L形的东西拿出来看,貌似是有些损坏。但是网上又找不到同样的ignitor,让我怀疑
它到底是不是一个ignitor。它就像一根粗铁丝,顺着gas管的方向伸进去,然后在里面
拐个弯,挡在gas管口的地方。
各位有人家里有类似的东西吗?请帮忙鉴定一下到底是不是ignitor,如果是,哪里有
的换配件?
谢谢! |

m********n 发帖数: 782 | 49 估价说$4800包furnace,parts和人工,不知道算不算贵。

|
z**********i 发帖数: 12276 | 50 昨天,好一切正常.
今天,furnace的风扇出了问题.如果thermostat设在auto,风扇就不转,点火没有问题
,因为风扇不转,过一会,火就自动灭了.只有把风扇设到on,才能保证风扇转,屋子
才会热起来.
问题,是控制风扇的电路板坏了,还是thermostat的auto挡坏了?
如何检查?
多谢! |
