Some info for you. wish it helps

You say (炉子还在运作, 停不了了, after 温控器调到off 的位置) is it only the Fan non stop working? Or the furnace/gas burning all working?

If the furnace problem is controller relate, 温控器调到off 的位置 can not prove the problem, you may want to test the funrace "CPU Controller" and ,

1: Power off the furnace completly, there is a switch in the furnace area,.
2: wait for 1 minute. check if the fan stopped.
3: Fan should stop after power is switched off.

4: After 1 minutes switch it back on,
5: If the fan running again after switched back on.
6: It mean the relay or the control circuit is "STUCK CLOSE"

PM me if you like, I can explain to you on phone. I am not a technician, but I look after my own home and my friend home for long time. Understand how it work and how to trouble shooting

  • 枫下家园 / 美丽家居 / 暖炉持续工作8个小时,但是其中热风是间断性的出来,就是说一段时间出热风,一段时间出冷风(并不是空调的冷风,而是室温的空气),所以工作了这么久还是达不到设定温度23摄氏度,请问会是什么问题? 谢谢
    • 1: make sure the fan is on "auto"; 2: are you sure it never reached to 23C?
      • 风扇是在auto的位置。现在炉子已经工作一天了,没停。好像每20分钟热风后就没有热风了,吹的就是室温的风。这样的冷风会吹1小时,这样温度总上不来。
        • 首先温控器的设定是否正确,即FAN设在AUTO上;再者如果是比较老的中效炉,在炉子内有个控制FAN是在ON还是AUTO的按钮,调整过来就好了。
          • 从来没有到23度,问题是炉子如果达不到设定温度应该继续吹热风啊?现在它不停的吹冷风(室温的风)。而且不停运作,是怎么回事呢?
            • 如果内部温度过高也会保护不点火的。
    • something wrong with the furnace, I guess, could be overheat and gas is shutdown automatically.
      • 现在我把温控器调到off的位置,炉子还在运作。停不了了。

        • 将FAN调到AUTO炉子就应该停止工作了。
    • 换上新电池后,再看一看
      • 热风有,就是时间短。如果按照小时计算,一个小时中,只有15分钟热风,然后就是正常的风。太奇怪了。
        • My furnace (air conditioning) cycles too fast (slow). Is there an adjustment?
          My furnace (air conditioning) cycles too fast (slow). Is there an adjustment?
          The factory default setting is fast, which cycles 1st stage at approximately 1.2° F and 2nd stage 0.75°F. If you prefer longer cycles clip jumper W905. This adjusts 1st and 2nd stage to 1.5° F and 1.2° F respectively.
          • 在那里调节?有调节开关的英文名称吗?谢谢
            • it is called "Cycles Clip Jumper" read the instruction manual for the thermostat,
              it is called "Cycles Clip Jumper" read the instruction manual for the thermostat,
              However, some of the "High End Expansive Thermostat" are programmed with "PID" control, also called "Smart Thermostat" which can not be modified. the smart PID can remember the furnace behavier, such as how lonw will it take to get the room temperature up to the set point, as well how off often will it cyale calling for heat,
              • tks a lot
    • I believe your furnace flame sensor is broken, or similar reasons, Check the link out and see what you can do.
