枫下家园 / 美丽家居 / furnace突然发生故障，启动几分钟后就停止工作，10分钟后又启动工作，然后启动几分钟后又停止工作，一直反复。有朋友知道该怎么办？谢谢 -bluestrawberry(icecream); 2009-11-16 (#5685199@0)

如果鼓风机坏了,就会这样. 你的出风口有热风吗? -johnnyzh(bubble); 2009-11-16 (#5685211@0)

有一点热风，但不是很明显。谢谢 -bluestrawberry(icecream); 2009-11-16 (#5685273@0)

我以前的暖炉就是这样的，鼓风机不工作了，炉子点火正常，到控制器延时一段准备启动时，鼓风机不动作，控制器只好又把火熄掉，就这样不停的折腾，后来是换了鼓风机的马达 -johnnyzh(bubble); 2009-11-17 (#5687212@0)

啊？我家的炉子就是这么工作的，启动不到5分钟，歇十几分钟后循环。不会对炉子不好吧？但我记得早晨从20度跳到22度时要连续工作很长时间。 -ai97(温酒吧地爱板); 2009-11-19 (#5691480@0)
我家的以前也是，找厂家来看就把点火的口拿钢丝擦干净了就好了。可能是积碳太多吧。 -facenorthface(北脸); 2009-11-19 (#5691552@0)
