Good afternoon everyone! I went to light the pilot light on my forced air unit last night and was unable to. There is not even a little sound of hissing with pushing the button over.

Why would the gas supply in just this one item stop - have gas hot water heater with no problem, so it's not the bill!

Condensation pipe backed up early summer with the dripping of the water over a 3 or 4 day period extinguishing the pilot light. Would this have done something major to the system?

Thank you for assisting!
