燃气热水器加热水失败

燃气热水器加热水失败  
你的热水器不加热水?从这里开始解决问题。  
如果燃气热水器不加热水,请执行以下诊断:

1 )要确保气体是打开的。转动旋钮来试验气体控制,以防止当你正在寻找点燃燃烧器内。取下金属盖在热水器底部,看看是否燃烧器和/或试点光在飞行员的天然气供应管端的小火焰点燃。

2如果指示灯熄灭)请在坦克上的说明重新点燃它。它也有可能是进气口阀门已关闭部分或全部的方式。如果是这样,转动把手平行线,重新点燃试验。如果试验将不亮,热电偶可能有缺陷,或者打电话给你的天然气公用事业公司(在许多地方免费服务)或设备翻修师傅。 (新热水器可能有辉光插头或火花点火器,而不是一个试点按照您的用户手册中的说明。 ) 
 
3 )如果燃烧器不亮,更换封面,并确保恒温器设置为大约120华氏度 如果不是,调整它,打开热水水龙头,然后等待几分钟,看看热水器燃烧器点燃。如果没有点燃,离开热水运行和尝试降低,然后提高温度对拨号设置,直到燃烧器点燃。

如果燃烧器点燃,更换封面,把恒温器回到一个适当的设置。如果燃烧器不点火,热水器有一个设备翻修师傅检查出来。这可能是因为热水器的恒温器有故障。置换是最好的留给 管子工。

4)气味的气体。如果你闻到大蒜的气味一样,把煤气阀控制为OFF (您可能必须把它推下来) 。等到气体气味面前二次照明灯试点消散。若气体气味强烈,不消散,立即关掉煤气阀,通风的空间,并调用从远程位置您的公用事业公司。

Gas Water Heater Fails to Heat Water

Is your hot water heater failing to heat the water? Start here to troubleshoot the problem. If it isn’t, adjust it, turn on a hot water faucet, and then wait a few minutes to see if the water heater burner ignites. If it doesn’t ignite, leave the hot water running and try lowering and then raising the temperature setting on the dial until the burner ignites.

gas water heater wont lightIf a gas water heater fails to heat water, perform these diagnostics:

1) Be sure the gas is turned on. Turn the gas control knob to PILOT to prevent the burner from igniting when you are looking inside. Remove the metal cover at the bottom of the water heater and look to see if the burner and/or pilot light—the small flame at the end of the pilot gas supply tube—are lit.

2) If the pilot light has gone out, follow the instructions on the tank to relight it. It’s also possible that the gas inlet valve has been closed partially or all the way. If so, turn the handle parallel to the line and relight the pilot. If the pilot won’t light, the thermocouple may be defective—either call your gas utility company (a free service in many areas) or an appliance repairperson. (Newer water heaters may have a glow plug or spark ignitor instead of a pilot—follow the instructions in your owner’s manual.)

3) If the burner is not on, replace the cover and make sure the thermostat is set to about 120 degrees F.

If the burner ignites, replace the cover and turn the thermostat back to an appropriate setting. If the burner doesn’t ignite, have the water heater checked out by an appliance repairperson. It could be that the heater’s thermostat is defective. Replacement is best left to a plumber. 

4) Smell for gas. If you smell a garlic-like scent, turn the gas valve control to OFF (you may have to push down to turn it). Wait until the gas smell has dissipated before relighting the pilot light. If the gas smell is strong and doesn’t dissipate, immediately turn off the gas supply valve, ventilate the space, and call your utility company from a remote location.
