The pressure switch is the device that proves that flow. It sits in the water path, senses pressure and closes a contact, and only then does the control let the burner light. If the switch fails open, the heater runs its start sequence and stops, usually with no obvious fault at the plumbing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCheck the switch you are removing.
