Lennox Furnace, plz help


I have Lennox furnace and when I turn it on, I hear tick tick noise and pilot is on, but it does not start fire until you blow some air with your mouth or some hard board. With the air you blow, it catches the fire and then heater works great except, I still hear tick tick noise. I tried cleaning, but nothing help.

Any idea what I need to replace?

It is Lennox Model # G16Q3/4-100-3 (Serial # 5889E17436)

Thanks for your help

You should clean the pilot orifice.

Usually use a 3/8 or 7/16 opened end wrench to remove the 1/4 inch pilot tube from the base of the pilot to gain access to the pilot orifice.

Be sure and use some dish soap mixed with water and check connections after you put it back together.
