York model P2MPD20N08001Dserial number: ECDM096728
decoding the model number based on this document: https://hvacdirect.com/hvac/pdf/Furnace-Decoder.pdf and the manual:
P=furnace.
2=US & Cananda (9=Canada).
MP=Upflow or horizontal (DP=downflow).
D20: Type Drive & CFM (X100), D=direct (V=variable). 2000 CFM.
N: Heating Fuel with N stands for natural; if L, then it stands for factory built Low Nox.
080: Nominal Capacity btu/h (X1000). Output Capacity (btu/h):80,000
01: voltage code. 01=120-1-60
D: Style. Cabinet Size Width: D = 24-1/2
interpretation of the serial number based on this document http://www.wsrar.com/wp-content/uploads/2013/07/York-Decoder.pdf: manufactured at Medina plant, March 1995. The numbers are meaningless.

summary
根据这个网上的配型 (https://www.repairclinic.com/PartDetail/Blower-Motor/S1-02423211003/2335554),我的电动机是Y48. 这个网上解释了 Y frame: https://www.inyopools.com/Blog/what-does-my-pump-motors-frame-fr-rating-mean/general concepts
s.f.1.0: service factor 1.0. means you can run a motor to 100% load, if it is 1.15, then it can be loaded to 115% of its rated load.室内空气循环
室内空气从一边(我这个就是右边)通过air duct进入,先通过鼓风机,然后便是天然气燃气炉,再通过空调的evaporator coil (冷媒蒸发器)便进入各个房间的出风口,当然也是通过air duct。这就是空气在室内的内循环。电容
capacitor 电容: lifespan 20 years. 电动机上有两根咖啡色的电线就是接到这个电容器上的。电容器不分正负极,不用担心接错。就是插上去的。一根线上有四个接线柱,接任何一个都可以,一个是正极一个是负极。但不能把两跟电线接在同一极上。现在中国或墨西哥出的电容器,是5万小时的寿命,一般情况下可以运转25年。自己换很容易,最保险是每15年就换一个,而且换这个不需要执照。先放电:用一个螺丝刀把正极与负极一连上就好,这需要百分之一秒就够了。然后就把新的换上,把两颗线分别插入两个极接线柱就完事。鼓风机
Called a direct drive blower (vs belt-driven).鼓风机上面电线
清洗鼓风机内侧和风轮
鼓风机风向
判断是否需要换新得电机
买新电机
air filter
air filter 我用没有圆孔的 3M 。有圆孔的或那种网子一样的过滤器,直接影响空调的效率热交换器
热交换器( heat exchanger), connected with a chimney. 这个燃烧室的材料其寿命保修有两种:一是99年,一是life time Warranty。不论是是哪种,90年的寿命是杠杠的。清洗空调的 evaporator coil
蒸发器有一面有管道是冷媒进出的,此面有螺丝固定铁皮,拧下螺丝拿下铁皮便可清理蒸发器了。在home depot 有两种以上的清洗蒸发器的喷剂,有一种带有软刷子,它是根据散热片的硬度造出来的,不会在刷洗时把散热片弄倒。这个活,男女都能干,就拧开几个小螺丝,就可清洗了。new furnace
