精华 急!!!暖气问题

[xiegen]

这两天暖气有问题了.设定是22度的,但是现在已经掉到14度了.
house, 前几天因为要换过滤网,所以关掉,然后再开,不知道是不是这个问题呢.
现在开,老是能来1分钟左右暖气,然后就停.把fan 拨到ON 也只是冷风
调节器电池昨晚也换了,还是没用....有没有人知道什么问题呢?

Furnace problem

I found out this morning that my furnace wasn't working. It is LENNOX, about 10 years old.

I suspect the pilot light was off due to the strong wind yesterday. Is it right? How to start the pilot light?

thank you

Try to take off the tube to the ventilation fan and let the air out. The valve might be shut.

Then put it back to see if the pilot light will be on. Good luck!

(就是照片上，由电机通向上方风门的灰白色细软管；也可看看下面那根透明塑料排水管（有水锈的那根）是否堵塞；还可以打开两个黑色塑料管道下方的橡胶封口，看看是否有积水。）

换过滤网 only take less than a minutes...you do not need to shutdown the power.
call the technician ASAP.. if you can not fix yourself

Many 10 years old furnace don't use pilot light. Are you sure your furnace has a pilot light. Try to find the operating manual, go to lennox website you should be able to find the document.

If it happened just after the changing filter, are you sure you putted in right filter.

I didn't think it was the pilot light as skiskyx said/thought. It could be that the LED on the module was not ON (shut off, no power), so the ignition didn't start.

furnace is working now for no reason

Can anybody explain why?

My furnace wasn't working this morning. I went to work without doing anything. When I went back home around 6 pm today. It suddenly worked, with a loud sound and burning smell. The furnace works as usual since then. The burning smell was gratually gone about half hour later. I checked the filter. The filter condition is good. I couldn't see any pilot light. Maybe it is a relatively modern furnace. 大家知道什么原因吗？我是否还是要找technician看一看？

谢谢

kind of have feeling , it is a blocked exhaust pipe(by ice or snow). Somehow it unblocked. But not sure. If it keep works fine for next few days, you don't need to call technician.

 

[skiskyx]

Where is the exhaust?

thank you for the kind reply. Do you know where the furnace exhaust is? Inside or outside?

You can see how it looks like from the outside.

On a Lennox furnace, it is right on top of it. The exhaust piple is black in colour... going up toward the ceiling and leading to the outside of your house, where you can see the exhaust smoke when the furnace is on.　（见上面新补的照片。左侧那根黑色塑料管是排废气管道。）

What Timothy's suggested could be correct. The warmer temperature in the afternoon helped melt the ice blocking the exhaust pipe outside of the house.

There's no way it will block as the temperature is quite good these few days. There' no snow/ice on the roofs at all.

Mostly as per CCC said

Try to take off the tube to the ventilation fan and let the air out. The valve might be shut.

If you open the furance door, you will see a blower about 6" in dia, there's a small plastic tube attached to it. If you find it, remove the tube to clean it and make sure there's no dirt as it will puck the tube and turn the safety switch off.

Is the following picture looks like yours?

我在上面补了照片。锅炉型号不同，看起来略有不同。但是，原理是一样的。
