加拿大华人论坛 加拿大生活信息Furnace不能自动点火

在加拿大

我家的暖气炉是york diamond90, 今天按照操作说明开始用的时候发现没有反应，设好了温度也没有自动点火。但是我发现在炉子下方有一个按钮，按着这个按钮，风机就开始工作了，过了几秒就看到点火器变红了，火也点着了。我担心温度达到后，暖气炉停了，等温度降下来以后还是不能自动点火。想请教有经验的同学，暖气炉出问题了吗？难道每次都需要手动去按这个按钮点火？我们是去年冬天搬到这个房子的，搬进来时furnace已经是开着的了，也从来没有手动去点火 都是设定好的温度，他自动控制的，到夏天就关掉了，现在想打开就出现这样的情况。谢谢了

炉子下方什么按钮？ Door switch? 拍个照片看看。

楼主你的炉子温度下来后, 能否又自动启动?

炉盖是其保护作用的， 就像洗衣机盖子一样， 打开就会停止工作了。

zhuan de 1) Is your filter dirty?A dirty filter is the #1 reason for your furnace to stop working due to overheating. In fact, it's responsible for a whopping 90% of all furnace problems! Simply change the filter and thenif the unit has a reset button, marked "RESET" near the motor housing, wait 30 minutes to let the motor cool, then turn the power off to the furnace and...2) ...press the reset buttonIf the unit still doesn't start, wait 30 minutes and press the reset button again. Repeat at least once more. By hitting the reset button this may fix any problem that you are having with your gas furnace. If your unit continues to not work properly after resetting it, then you will need to call a service technician3) Is your door cover on correctly?If it is not on just perfect, your furnace will not start. This happens commonly after a filter change.4) Are too many registers closed?Do not close off more than 20 % of the registers because this can cause high resistance and unnecessary heat build up in the furnace.It's OK to close some registers to save on energy costs if rooms are unused...but do not exceed 20%. So if you have 10 rooms, you should only be closing a maximum of 2 registers.5) Is the furnace switch in the "ON" position?It may have been turned off by mistake.

把filter拿出来，看看能不能自动启动，如果灰尘太多导致overheating也不会启动的。

另外你可以通过调控thermostat进行排查。假设你设定24°，当室内温度降低后，furance会自动启动(显然你的情况是没有自行启动)。你可以调节thermostat到低于当前的室温，比如20°。过30秒以后，再重新调节至24°，看看furance能否启动。

不过我严重怀疑是你的drainage hose堵了。

评论
谢谢大家的热心回答，炉子已经好了，就是盖子没盖好的原因。
