1. 检查恒温器

First, ensure your thermostat is instructing your furnace to turn on.

数码恒温器

• Swap out the batteries if the monitor is not displaying anything. 如果数字屏幕出现故障，可能需要更换恒温器.
• Make certain that the button is on “heat” rather than “off” or “cool.”
• 确保程序设置在正确的日期和时间，并设置为“运行”.” If you’re having problems turning off the schedule, 设置温度与向上/向下箭头和按下“保持”按钮. This will cause the furnace to turn on if thermostat is causing trouble.
• 将温度设置为比室温高5度.

If your furnace hasn’t started within a couple minutes, 把风扇开关从“自动”切换到“打开”，确保有电.” If the fan doesn’t begin to run, your furnace may not have power.

智能恒温器

If you use a smart thermostat—like one made by Nest, Ecobee, 勒克斯, 霍尼韦尔或博世的故障排除将取决于您的型号. Check the manufacturer’s website for assistance. If you’re still unable to get your Wi-Fi thermostat to function, bg真人官网在 for heating and cooling service.

2. Examine Breakers and Switches

Next, confirm your breaker and furnace switch are on.

• Locate your main electrical panel. 如果你不确定它在哪里，可以在地下室、车库或壁橱里找一个银色的金属盒子.
• 打开面板或断路器前，请确保手和脚干燥.
• 寻找标题为“炉”或“热”的断路器，并确保它移动到“上”.” If the breaker has tripped, it will be in the middle or “off” position.
• With one hand, steadily turn the breaker to the “on” position. If the breaker instantly trips and pops back to “off,“不要试图重置它，并迅速联系bg真人游戏登录的团队成员.

Regardless of your furnace’s age or brand, it has at least one regular wall switch located on or close to it.

• Make sure the lever is flipped up in the “on” spot. 如果它被关闭，你的炉子可能需要五分钟才能启动. (If you’re unaware of where to find your furnace, take a look at your basement, garage or utility closet. It may also be in a crawl space or attic.)

3. Get a New Air Filter

当我们考虑到供暖故障时，肮脏的、满是空气的过滤器往往是罪魁祸首.

If your filter is too grungy:

• Your heat won’t stay on, or it could get too warm from restricted airflow.
• 你的取暖费用可能会更高，因为你的炉子运行更频繁.
• 你的热量可能会过早下降，因为一个肮脏的过滤器会导致它过度工作.
• 如果过滤器过度堵塞是触发断路器的原因，您的暖气可能会被切断电源.

Depending on what make of heating system you have, 您的空气过滤器可以在您的供暖系统的鼓风机室的内部找到, an attached filter case or wall-mounted return air grille.

To replace your filter:

• 关掉暖气.
• Remove the filter and tilt it toward the light. If you can’t view light through it, replace it.
• 放入新的过滤器时，箭头朝向炉膛，以防损坏.

扁平过滤器应每月更换一次，而褶皱过滤器应使用约三个月. 如果你有孩子或宠物，你可能需要尽快安装一个新的过滤器.

To make the procedure easier down the line, 在加热器外部或管道系统上使用永久性笔来显示气流方向和过滤器尺寸.

4. Look at the Condensate Pan

通常被称为排水盘，冷凝盘可以容纳加热器从空气中去除的液体.

如果液体从你的加热系统或锅里有太多的水, try these guidelines.

• 如果你的平底锅有排水管(找一个聚氯乙烯管道)，确保没有堵塞. If it needs to be drained, 使用一种在家装店或五金店可以买到的特殊的清洁盘片.
• If your pan contains a pump, check the float switch. 如果锅内有水，开关不能从“向上”位置移动, bg真人官网在 , because you will probably have to get a new pump.

5. Check for Furnace Error Codes

如果故障仍然存在，请在您的加热器的塑料窗口内查看风机电机的状态. 根据品牌的不同，灯也可能固定在你的供暖系统的外部.

If you note anything other than an uninterrupted, colored light or flickering green light, reach us at for HVAC service. 您的加热器可能正在传递错误代码，需要专业协助.

6. Scrub the Flame Sensor

如果您的供暖系统试图启动，但关闭了，而没有把热空气, a filthy flame sensor could be responsible. 当这种情况发生, 你的炉子会尝试启动三次，然后安全装置会关闭它大约一个小时.

If you feel confident with removing the panels from your heating system, brushing off your flame sensor is a job you are able to do on your own. 或者，我们的供热服务专家有能力为您完成.

If you want to clean the sensor yourself, you should have:

• A 1/4” hex screwdriver or wrench
• Portion of light grit sandpaper, steel wool or emery cloth
• 干净的纸巾

然后:

• Disable the heating system’s power by using its wall switch or breaker. 如果你没有电动煤气阀门，你也需要关闭煤气.
• 抬起加热系统的前面板，沿着电线走到火焰传感器上.
• 取下金属棒，用砂纸、钢丝棉或砂布轻轻摩擦金属棒.
• Clear the rod with a paper towel.
• Screw the sensor back in.
• Put the furnace doors back on.
• Switch the furnace’s power back on. It may go through a set of tests before continuing regular heating. If your furnace doesn’t ignite, 传感器可能需要更换，或者其他可能产生问题的东西. 如果发生这种情况，请与我们联系，寻求加热和冷却bg真人官网援助.

7. Reignite the Pilot Light

If you have an aging furnace, the pilot light could be out. 要点燃它，在你的加热系统上找到一个方向，或者试试这些指南.

• 找找加热器底部标有“先导”、“开”和“关”的开关.”
• Push the switch to the “off” position.
• Wait at least five minutes to avoid starting a fire.
• Turn the dial to “pilot.”
• 当你移动一个长打火机的火焰到先导灯开时，按下“重置”按钮.
• Let go of the “reset” button once the pilot light is burning.

如果你已经尝试了两次指南，先导灯仍然不亮或保持燃烧, bg真人官网在 for furnace service.

Check Your Fuel Source

Try using a second gas appliance. If it doesn’t function, your natural gas delivery may be switched off, or you could be out of propane.
