I have a Lennox Whisperheat gas furnace model no. G20Q3/4E-125-2. On normal start up the pilot would light and then there would be a click click click noise several times then the burner would light and the blower would kick on. Now what is happening is the pilot lights and then the clicking starts clicking super fast, the burner never lights but the blower kicks on. No heat! Any ideas? Thanks!

You may have a dirty pilot orifice and its not hitting the flame sensor to tell the main burners to kick on. On some furnaces the blower will come on 90 sec. after the thermostat calls for heat even if the main burners are not on.
