A furnace is crucial for comfort and survival in cold winter weather. Without it, we would still be huddling around wood fires to stay warm. Unfortunately, furnaces need regular professional tune-ups and homeowner upkeep to run strongly and efficiently.
\r\n

\r\n

Even with proper maintenance, however, furnaces can break down and develop problems that impede regular functioning. If your furnace is acting up or refusing to turn on, go over these furnace troubleshooting tips first, before you call in the pros.

\r\n

1. Check furnace filter

\r\n

The first thing you want to check is the air filter. Over time, furnace filters get dirty. Dirt and dust can quickly clog the filter, which impedes airflow, worsens indoor air quality, and can even prevent the furnace from turning on in some cases. It can also become a fire hazard and cause premature breakdowns due to excessive dust and dirt.

\r\n

\r\n
• Turn your thermostat off and flip the furnace switch off before you conduct any work on the furnace.
\r\n
• Check your air filter every 30 days (set calendar reminders).
\r\n
• Hold your filter up to a light source — if light cannot pass through easily, it should be cleaned or replaced.
\r\n
• When installing your new filter, remember that the arrows should point in the direction of the airflow.
\r\n
• Make sure you properly secure the access panel.
\r\n

\r\n

2. Check the thermostat

\r\n

After verifying that your furnace filter is clean and installed properly, check the thermostat.

\r\n

\r\n
• Make sure it is set to “heat” and try setting the temperature at least 5 degrees higher than the current room temperature.
\r\n
• If the thermostat needs new batteries, replace them.
\r\n
• For electromechanical thermostats, you may need to open it up and give it a gentle dusting. Use a soft paintbrush or something similar to lightly brush off dirt and dust, including around the metal coils and contact plates. If your brush is too large, try a soft paper.
\r\n
• Check the location of your thermostat and make sure it isn’t receiving any false readings from sunlight, lamps, ovens, space heaters, or any other heat source. If the thermostat is receiving the wrong input, it will send out the wrong output.
\r\n

\r\n

3. Check furnace switch and electrical panel

\r\n

Sometimes, the filter and thermostat are fine. Instead, power could be the problem.

\r\n

\r\n
• Check the furnace switch located near the furnace. Someone may have accidentally turned it off. Try flipping it back on. If that doesn’t work, head to the electrical panel.
\r\n
• Make sure power is turned on at the breaker box or fuse box.
\r\n
• If your breaker box is properly labeled, make sure the HVAC breaker is on. Even if you don’t have any labels, look for the breaker switch that is in the opposite direction of the rest. That is the breaker you want to switch back on with the rest.
\r\n
• To reset your breaker, flip the switch all the way off before flipping it back on again. You should hear a click.
\r\n
• To restore power to a fuse box, look for a melted and discolored fuse. Unscrew the fuse and replace it with the exact same size and type of fuse. The best way to find fuse replacements is to go to the store with a current fuse and replace it with an identical one.
\r\n
• Turn your furnace switch on and see if this restored power to your furnace. If the power is still out or the breaker continues to trip, contact a professional.
\r\n

\r\n

Warning: Make sure your hands and feet are completely dry before attempting to reset power. If there are any signs of electrical damage or moisture, or you don’t feel comfortable, don’t touch anything and contact a qualified electrician right away.

\r\n

4. Check furnace flame

\r\n

Your furnace flame should be a healthy blue color, with perhaps a small yellowish tip. The blue flame indicates that your gas furnace is burning the fuel safely and efficiently.

\r\n

If the flame is red, yellow, purple, green, or any other color than blue, contact a professional right away. Never attempt to fix your furnace flame color on your own.

\r\n

5. Pilot light and gas valve

\r\n

If you go to check the furnace flame and it is out, you will need to relight it. While you can relight the pilot on your own, be extra careful and consult your owner’s manual for proper instructions.

\r\n

Don’t forget to turn off the gas for around 10-15 minutes before attempting to relight the pilot. If you continue to smell any gas, do not continue! You may have a leak, in which case, you should evacuate the household immediately and call your gas company and the fire department at a safe distance.

\r\n

If you have any doubts, don’t hesitate to contact us.

\r\n

6. Properly secure front panel

\r\n

Follow your manufacturer’s instructions for properly securing the access panel. Many furnaces will not operate if the panel is not pressed in all the way.

\r\n

7. Ensure all vents and registers are open and unblocked

\r\n

Sometimes, your furnace is running but your rooms aren’t getting the proper heat or airflow. Inspect your entire home for all the supply and return grilles. They should all be fully opened and unobstructed.

\r\n

Make sure there are no rugs, furniture, or anything else restricting the flow of air. Not only will blocked vents and registers affect your comfort, they can also lead to duct leaks due to excessive air pressure and premature HVAC repairs and breakdowns. Closing off vents and registers in unused rooms is NOT a good idea. You won’t save any extra money and will end up causing more problems for your heating system.

\r\n

Furnace Troubleshooting Recap:

\r\n

\r\n
1. Clean or replace air filter
\r\n
2. Troubleshoot thermostat problems — replace batteries if necessary
\r\n
3. Set thermostat to heat and at a higher temperature than the current room temperature
\r\n
4. Check electrical panel for blown fuses or tripped breakers
\r\n
5. Make power switch near furnace is flipped on
\r\n
6. Check pilot light, relight pilot light if needed
\r\n
7. Open all vents and registers
\r\n
8. Properly mount and fasten access panels (as a safety mechanism, some furnaces won’t turn on if access panels are not properly installed)
\r\n
9. Contact a qualified HVAC professional
\r\n

\r\n

When in doubt, call a professional

在寒冷的冬天，火炉对于舒适和生存至关重要。没有它，我们可能还在围着柴火取暖。不幸的是，炉子需要定期的专业调试和业主维护才能强劲有效地运行。

然而，即使进行适当的维护，熔炉也可能发生故障，并出现阻碍正常运行的问题。如果你的炉子出了问题或拒绝打开，在你打电话给专业人士之前，先看看这些炉子故障排除技巧。

1.检查炉过滤器

首先要检查的是空气过滤器。随着时间的推移，炉膛过滤器会变脏。污垢和灰尘会迅速堵塞过滤器，阻碍气流，恶化室内空气质量，在某些情况下甚至会阻止炉子启动。它也可能成为火灾隐患，并由于过多的灰尘和污垢导致过早故障。

• 在对炉子进行任何操作之前，关闭恒温器并关掉炉子开关。
• 每30天检查一次你的空气过滤器(设置日历提醒)。
• 把你的滤镜放在光源前——如果光线不能轻易通过，就应该清洗或更换滤镜。
• 当安装新的过滤器时，记住箭头应该指向气流的方向。
• 确保你安全的进入面板。

2.检查恒温器

在确认您的炉过滤器是清洁和安装正确后，检查恒温器。

• 确保将其设置为“加热”，并尝试将温度设置为至少比当前室温高5度。
• 如果恒温器需要新电池，请更换电池。
• 对于机电恒温器，你可能需要打开它，给它一个温柔的灰尘。使用软漆刷或类似的东西轻轻刷掉污垢和灰尘，包括金属线圈和接触板周围。如果你的画笔太大，试试软纸。
• 检查你的恒温器的位置，确保它没有收到任何来自阳光、灯、烤箱、取暖器或其他热源的错误读数。如果恒温器接收到错误的输入，它就会发出错误的输出。

3.检查电炉开关和电气面板

有时，过滤器和恒温器都没问题。相反，电力可能是问题所在。

• 检查炉子附近的炉子开关。可能有人不小心把它关了。试着重新开机。如果不行，就去电气面板。
• 确保断路器或保险丝盒上的电源已打开。
• 如果你的断路器箱贴了正确的标签，确保暖通空调断路器是开着的。即使你没有任何标签，寻找断路器开关是在相反的方向。这就是你要和其他开关一起打开的断路器。
• 要重置断路器，请将开关全部关闭，然后再重新打开。你应该能听到咔哒声。
• 要恢复保险丝盒的电源，请寻找融化和变色的保险丝。拧下保险丝，换上完全相同尺寸和类型的保险丝。找到保险丝替代品的最好方法是去有当前保险丝的商店，用一个相同的保险丝替换它。
• 打开炉子开关，看看是否恢复了炉子的电力。如果仍然断电或断路器继续跳闸，请联系专业人员。

警告:在尝试重启电源之前，请确保你的手和脚完全干燥。如果有任何电气损坏或受潮的迹象，或者你感到不舒服，不要触摸任何东西，并立即联系合格的电工。

4.检查炉膛火焰

你的炉子火焰应该是健康的蓝色，也许有一个小的黄色尖端。蓝色火焰表示燃气炉正在安全有效地燃烧燃料。

如果火焰是红色、黄色、紫色、绿色或蓝色以外的任何颜色，请立即联系专业人员。永远不要试图自己固定你的炉子火焰颜色。

5.指示灯和气阀

如果你去检查炉子的火焰，它是熄灭的，你需要重新点燃它。虽然你可以自己重新点燃，但要格外小心，查阅用户手册以获得正确的说明。

在试图重新点燃领航员之前，不要忘记关闭汽油大约10-15分钟。如果你继续闻到任何气体，不要继续!你可能有泄漏，在这种情况下，你应该立即撤离家庭，并打电话给你的煤气公司和消防部门在一个安全的距离。

如果你有任何疑问，尽管说联系我们．

6.前面板安全

按照制造商的说明正确固定检修面板。许多炉子如果面板没有完全压紧，就无法运转。

7.确保所有通风口和寄存器都打开并畅通

有时候，你的炉子在运行，但你的房间没有得到适当的热量或气流。检查你的整个房子的所有供应和返回格栅。它们都应该完全打开，畅通无阻。

确保没有地毯、家具或其他限制空气流通的东西。堵塞的通风口和寄存器不仅会影响你的舒适度，还会导致管道泄漏，因为空气压力过大，暖通空调维修和故障过早。关闭闲置房间的通风口和收银台不是一个好主意。你不会节省任何额外的钱，最终会给你的供暖系统带来更多的问题。

炉故障诊断概述:

1. 清洗或更换空气过滤器
2. 排除恒温器问题-如有必要更换电池
3. 将恒温器设置为加热，温度高于当前室温
4. 检查电气面板是否有熔断器或跳闸
5. 使炉膛附近的电源开关打开
6. 检查领航灯，如有需要重新点亮领航灯
7. 打开所有通风口和寄存器
8. 正确安装和固定接入板(作为一种安全机制，如果接入板安装不正确，一些炉子将无法启动)
9. 联系合格的暖通专业人员
