严重警告：

本文仅供参考。

Oil Burner修理维护过程涉及燃油、高压点火电压。请适当评估危险系数，把Oil Burner修理维护工作留给专业人士。

如果自己动手造成后果自负！！！

感谢网友Sean提供咨询帮助！！！

烧油的炉子出问题了。

症状：burner开始能自己点火启动，能闻到油味儿。之后越来越严重。最后炉子不能自己启动。

摁reset button，可启动，观察火焰不持续，燃烧几分钟后熄灭，并有浓重的油味儿。

基本诊断：

1）点火变压器（transformer）应该没问题。

2) cad cell sensor (flame sensor)应该没问题。

3）基本判断是进油的问题。开始清理喷油嘴（nozzle).

最后更换了oil filter，问题得到解决。

结论：oil filter建议每年都换。

Filter housing (4 inch 左右直径)

Home depot店里有。早上去买一个。/::D

which one in stock at HD?

RF4B/RF4

looks like the right one. I recommend you buy both types that I gave links for, just in case, pick one to use.

1. Shut off oil supply before the filter

2. Loosen the single bolt on the top, filter housing will drop down

3. Replace filter and all 3 gaskets

4. torque the bolt to 10 ft.lb

5. Bleed the line

右下角是bleed connect fitting?

4-5 o'clock

6 o'clock shinny one

和bleed刹车油一样？

4 o'clock in my picture

similar, except that, in oil furnaces' case, the pressure is constantly positive so there's no risk of suck-backs

动手之前关掉电开关

打开transformer

严重警告：就算断了电，transformer可能会带高压(高压！！！！）就是图中两个弹簧状触点。

中间黑色的管状物就是 cad cell sensor (flame sensor)
