某日发现Dryer(电加热)滚筒运转但是没有热气,拆开机器找到四个fuse,用万用表
测了下发现其中一个Thermistor电阻很大,就买了一个新的,等新的到了,一测电阻新
旧Thermistor的电阻都很小,不知道是不是旧的自己恢复链接了。把新的Thermistor换
上,dryer运行正常,也开始制热,但是放进衣服烘了一会儿又不制热了。我猜测是什
么地方不对,导致管道温度过高,然后Thermistor断电。有可能是什么地方出问题了呢
?有无一个checking list?

来自主题: Automobile版 - Thermistor or new window motor?
车窗户时好时坏。很可能是motor 不正常工作了。
看了网上一些介绍,说是motor 不工作多半是thermistor 坏掉。有人直接把它short
circuit 就正常工作了。坏处是失去了保护电路。
请问有没有可能只换thermistor? 哪里找到合适的。
如果不行,是不是只能换motor? 网上价格好贵,小小的motor,一个都在50--80块。
这难道不是几块钱一个的小电动机吗?
多谢指教!!

Mitigation of propagation of thermal runaway in a multi-cell battery pack
A method of mitigating propagation of a thermal event in an energy storage
system having a plurality of cells is disclosed. The method includes the
steps of identifying the heat sources within the energy storage system and
plurality of cells. The method then controls a temperature of the energy
storage system and plurality of cells and also detects predetermined

来自主题: Automobile版 - X5为啥双排气管只有一边出气?
Q: Why is the exhaust coming out of only the right side?
In order to enhance the exhaust note emanating from the tailpipe(s), BMW has
arranged a thermistor switched, electrically controlled, vacuum operated
butterfly valve to close off the tailpipe on the driver's side while the
engine warms up. This results in a more pleasant exhaust note when you are
first pulling out of your neighborhood.

其他条件相同的情况下应该是的。不过一般这个“同样条件”在一所房子里很难实现:
比如到furnace的air duct长度,到thermistor的距离什么的。我家虽然没有garage上面的屋子,但是房子最角上,
离furnace最远的那个房间最冷。所以我猜如果garage上面的房间如果离furnace近的话
应该能补偿一些吧?

来自主题: Living版 - 冰箱坏了
就是不制冷,是一点都不,突然地
Evaporator Fan is ok, no ice one coil
Condenser Fan is ok, coils just cleaned
开始怀疑是Start Relay/Capacitor, amazon定了个,刚换上,compressor 确信 works
Thermistor: 打到off, 所有Fans就停止,应该没问题
现在怀疑是氟利昂没了,那样俺就放弃了;但查了下说如果关掉冰箱电源,还能听到回
流的声音的话,氟利昂还有。俺能听到,如果不是幻听的话。
现在没招了,在lowes定了个三星的,希望寄出前奇迹出现
中午刚把chain saw搞定,在前后院猛砍了通,爽了还没多久

我的三星(尼玛,保险只有一年)同样问题。
症状是,冷藏温度显示闪(表示不能达到设定的温度)。开始有风扇噪音。好了几天,
没声了也觉不到里面出风口有风出来,温度到了50度以上。
打开时很费事,因为冰把能拿下来的前面板跟后面冻在一起了。掀开一块往里吹热风化
开。风扇上被冰冻实了。
查了一下会有下面可能:
1)风扇坏掉不循环风
2)面板不严潮气进入结冰过多化不过来。
3)thermo fuse除霜时不加热 。
4)电热丝坏掉不加热
5)thermistor坏掉不能在需要的时候接通电热丝。
6)主控板坏掉。
我把冰化掉后把冰箱进入forced defrost mode电热丝是热的,说明fuse和heater都没
问题。风扇化冰后也转。暂时装回去了回头看几天再有问题。

来自主题: Living版 - 版上有修冰箱的高手吗?
我的冰箱突然制冷不行(能达到冷藏室的要求,但是冷冻冻不住东西),compressor,
但是从expansion valve出来的管子摸着不是很凉,我把冷冻室的后面板打开,可以看
到evaporator的下面1/3有霜,应该是在制冷,但是上面2/3没有霜。我查了
freezerthermistor,evaporator thermistor,defrost limiter thermostat,都是好
的,compressor relay和电容应该也是好的,这是什么原因呢?佛里昂不足?对了,
compressor的风扇,和冷冻室里那个evaporater的风扇都是转的,冷冻到冷藏的那个通
风口也没堵。冰箱是GE的。万分感谢。

do you clean the filter each time?

Filter没问题,每次都清理了的,这次拆开机器把内部管道也都清了一遍,倒是vent没
检查,不过我也只能看到进墙前一段,墙里面就估计很难检查了。不过我可以尝试把出
风口和vent断开看看机器是否能正常制热

来自主题: Living版 - 问一下imore帅锅
上照片,至少要给个型号之类的,爱摸就能帮你了。常见的是ECM马达里的thermistor
烧了,如果那部分没有被环氧树脂封死,换一个就行。最坏结果是换Motor,看你还有
没有保修。

我家南北朝向。卧室朝南。 楼下朝北的厨房和客厅。 只要做饭。穿短袖都热。楼上气
温72晚上。76白天。
检查你的出气口。冬天楼上关掉。只开楼下的。 夏天反过来。
再检查一下你的 furnace and thermistors。我家以前开76都冷, 换了一个69都热。

Yes I used her method to marinade. I baked for about 2hrs for a 5+lbs whole
chicken at 350F. Best way is to buy a thermistor. If you don't have one,
there is a calculator for how long you should bake.

来自主题: Hardware版 - 求推荐机箱
安静和散热就是个balance的问题, 扇子大可以安静,还有就是
弄个controller, 随时可以调,
或者自控, 用2个thermistors做sensor, 对比机箱内外的温度
接到个op amp 然后到个power transistor, 装个 potentiometer
以被不时之需
水冷 如果pump 不给力, radiator 小还不如 on air
即使pump 给力, radiator 大, 要迅速散热还是要扇子

It looks like a thermistor (Thermal Resistor). is that coming from your rice
cooker?
you may buy it in a local electronics store or buy it online.

The function of thermistor is to keep the temperature constant.
depending on where you live, I used to bring the broken part to the local
electronics store, and let them find a new part with the same electrical
parameters. you can ask your friend to see if there is any store selling
electronics components in you area. if you can read the label on the broken
part, you can try to google it. you may be able to find the exact same part.
the two terminals look different. I am not sure if the polari

I just did the test. You are right. The lasing wavelength is shifted to be
around 1581nm when I am driving a current (125mA) only with the middle
contact meanwhile the TEC temperature is set to be 40C. The threshold
current at T=40C is up to 110mA compared to 70mA at T=20C.
For the case of TEC location, our device is attached on the surface of a
piece of bulk AlN.The bulk AlN is on the top of a copper stage. There is a
thermistor inside the stage,and the stage is on the TEC. In this case, I
