Steve, As Roger Berke suggested remove the Control Unit (brain box) from the burner. Now, the item you tap that starts the burner will show the culprit.
If tapping the box starts it, bad box. If tapping the black burner starts it, bad motor.
If the box is bad, I really like the new Aqua Hot designed and manufactured Control Unit, WPE 300 901. It is all solid state, no moving parts or relays. But it retails for only $934. It has been very good since they came out.
I can offer you one if you should wish.
