家里暖气温度上不来，什么原因？

bingtong · 发表于 2014-11-11 09:23

这两天天气突然降温，家里的暖气温度就是上不来，设到23度，可就是上不来，家里温度在18度左右徘徊。暖气出风口不时起动出风，但出来的风几乎不热，没啥温度。晚上睡觉二楼只有十六七度，是什么原因呢？这大冷的天，不知道咋办？

我家的类似，有时候还出冷风，温度还没有到设定值

So do I. I reset the goal temperature 21 celsius degree again, and then the furnace works again and send warm wind.

Check the followings:
1. Air filter is clean? most time dirt filter restricts the air flow, even it will shut down the furnace if there is too much air pressure loss on the air filter ( there is air differential pressure sensor to cut off the furnace)
2. Furnace start-up sequence check: most furnace shall be: start-up signal relay on click sound, exhaust induce fan (small fan) on ( purging air), ignition on, flame on, then main blower on which has big sound and bring the air to your rooms
3. In front of the furnace, check if there is any flame on during the start-up. You can see the flame thorough the small openings of the furnace cover.
4. if there is flame on then off, ( the blower will still be on for a while) most probably it could be the overheating cut-off sensor interlock the flame, due to some restriction of the air flow in the system.
5. if there is no flame on at all, could be the ignition is no good or exhausting temperature sensor at exhausting duct not good and interlock the ignition....
6. Check the bottom cover of the furnace, there is a round glass. Look thorough if there is any red led light flashing. if there is any fault, this led light will flash two different speed then stay for a while. then flash again. Give me the number first fast flash, and the number of the second slow flash. according the number of the 2 flashings, you can check the fault code right in the front of the furnace cover. It will tell you what is the problem.

In your case, most probably could be the overheating sensor cut-off if the furnace start/stop very often but no heat coming out from vents, due to some restriction by air flow, vents, ...But it needs more check out yourself and let me know if you need more instruction.

You also can call ATCO for check up once every year for free. text me at: 7808802698 if you prefer sharing my HVAC experience.

谢谢你的耐心指导，老公按照上面指示都去检查了，没有什么问题，现在他是怀疑控制面板上可调整火焰持续时间，但是这个调整要求专业知识。请问他的思路正确吗？

If he see the flame on, that will be two things to check out:
1. How long the flame last, if only few seconds, less than a minute, that could be a flame detector is not working, it does not detect the flame and shut down the furnace. Just clean it and let it aim to the flame.
2. If the flame last for a while, it could be the overheat temperature cut-off as mentioned above.
Normally there is no adjustment for the flame timing, only can adjust the flame size which needs a pressue meter or professional person to do it.
Text me when he is checking the furnace if he likes to. 780-880-2698

我们家前几天刚遇到这个问题，幸好是夏天换的暖气所以furnace公司就过来维修。结果是告诉我们因为我们是买的旧房子，链接furnace和温度调节器之间的线路老化，温度调节器没办法真的启动furnance，所以维修人员暂时帮我们换了电线，现在furnance工作良好，但是还是建议我们找专业电工重新wire一下。不知道这个经验会不会对大家有帮助，前提是我们买的是几十年的旧房子

冬季我觉得室内温度低一点免得温差太大，

我自己觉得冬季室内外温差太大就象夏天空调开太猛

容易感冒。我自己这么觉得的
