周五也我炉子和你一样的情况,请师傅来看了,结果是风扇工作不正常,建议换风扇电机,找了半天,但是周六dealer好像不上班,所以自己漏夜学习电机知识,通宵作业,结果成功修复风扇电机, heating 在半夜2点一刻重新正常运作。你的情况估计是风扇工作不正常,点火后热量无法传输出去,造成温度高,系统自动停在点火, 所以我认为还是风扇的问题。
Looks like flame signal is too low, double check error code to verify it.
You are looking around 350 dollar to get it fixed during holiday or you want wait until Tuesday for half price.
给dealer打电话,technician说是flame sensor.要260加税之类的。有人有过类似问题吗?
1. Check Item2 (Induce Motor). If it works, go next; if it doesn’t work, order new one.
2. Check Item 13 (Gas Valve). Use a multimeter to measure the Resistance of the valve solenoid coil, the reading should be around 1kΩ. If so, go next; otherwise order new one.
3. Check Item9 (Flame Sensor). Lightly clean the surface with fine emery cloth (120 and up).
曾经有两次点火成功,但是10-20秒后又熄火了
竟然工作了三分钟,感觉不是大毛病。
关掉锅炉的电源,等一、二分钟后再送电。
That should be a problem with pressure switch. http://bbs.comefromchina.com/forum43/thread1202297.html

简言之:电脑检测认为满足点火条件,启动了送风电机,点了火。
但是点火后发现状态不安全,如供氧,供气,排CO2,燃烧温度过高等,所以自动熄火!
