谢谢。是Spark Ignitor。
找人来看了看，请大家看看有道理吗？之所以，因为咨询了另外一个人，没有来亲自看， 他说spark ignitor不太可能坏，他觉得是主板坏了。
“Inducer keeps coming on and and off after every 20-30 seconds. I would hear a click from the board right before the inducer motor turns off. I opened up the unit. Took an Amp draw of the inducer motor. Got 0.6A. Which is below the 1.05 max Amp rating on the motor. I then made sure the pressure switch is making a close connection while the inducer motor runs. I then took a mili Amp draw on the igniter. It will pull 0 amps when the board tells it to spark. I then checked voltage and got proper voltage. I then cleaned the igniter and put it back it. Tested it and still does not spark. After testing everything that I could I concluded that the spark igniter is bad and needs replacing.”

ignitor is less 20 dollars. Just buy one, change it, and see whether it works or not. If it doesn't glow, the chance is high that it is bad.united 写了： 2023年 10月 21日 17:09 谢谢。是Spark Ignitor。

Don't change the board until you rule out everything else.
I own many properties and I have yet seen one case where the board is bad. I have seen everything else.

Check the flame sensor. It's a metal stick. Clean it with a dollar bill.

有可能是主板坏的。主板上几个继电器有可能不工作的，我碰到过一起。wildthing 写了： 2023年 10月 21日 17:24 ignitor is less 20 dollars. Just buy one, change it, and see whether it works or not. If it doesn't glow, the chance is high that it is bad.

不过那都是15年以上的炉子
楼主既然点火器换了，那至少可以看到火焰。如果火焰看到了仍然断掉，那就是flame sensor脏了。
#32 Re: 求助：HVAC没有热风
是igniter？ amazon买了一个试了还是一样的
zmimy 写了： 2023年 10月 27日 16:29 九年的炉子很可能是点火器坏掉了。
换一个几十块钱，也非常简单
自己查型号到amazon上面买一个。也可以到local hvac零件店买一个。

没有火焰..

那你看见spark了吗？看见火焰了吗？united 写了： 2023年 10月 27日 16:35 不是那种点火的
是spark igniter

主板上有个显示“H”/"C"的地方，显示H之前出现了5，7，3
不知道是不是大家说的code？
如果是57的话，说明书上写着“ PRESS SWITCH STUCK OPEN WHEN SHOULD BE CLOSED”。
那个3就不知是什么意思了。
之前那个technician诊断肯定错了...
