IMO, if you hear the clicking then all your electrical stuff is OK otherwise ignition would not be attempted. Stand outside by the exhaust and see if you can smell propane during the clicking. I'm guessing your jet has debris in it. When you pulled it, and took it to CW it shifted and now it's back.
That's if the click was actually the spark electrode and NOT just relay/module...depends on IF FAN comes on or doesn't
No Fan then relay/module or even sail switch stuck closed.
OP needs to post what it is doing and what it ISN'T doing along with model
Well you must have ears like a rabbit, because all I can ever hear is the sparker. Also you're off the fan comes on prior to sail switch and the relay prior to fan is heat based, no clicking.
If it has a bad stand alone timed delay relay it can 'click'
If bad relay is on circuit board it can 'click'
If sail switch is stuck closed...you can hear just a 'click' and nothing will run
If motor is bad you can hear a 'click'
Click could be just at t-stat when contacts close
YES besides spark electrode there are other things that can 'click' and spark electrode will click repeatedly for 6-8 seconds
That is why OP needs to respond and explain with more info.
