After my pilot lights on my Lennox WhisperHeat furnace, shortly after there is a clicking sound (sounds like a switch) immediately before my burner ignites, however instead of clicking once as it used to, it is now clicking about 4 or 5 times before the burners ignite. Can someone tell me what this is? Thanks!

Try to determine if the "clicking" is coming from the ignition module or the gas control. Both will be visible with upper front panel removed.
