It is the genuine Raypak part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe pressure switch is a safety interlock. It watches the water side of the unit and closes when there is pressure, which is the control system permission to run. Without that signal the unit stays off, which is exactly what you want when the pump is not moving water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing a no heat call\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA unit that will not start and reports a flow problem is not always a bad switch. Start with the obvious water side causes: a loaded filter, a closed or partly closed valve, a clogged pump basket, air in the system. If the water is moving properly and the switch still never closes, the switch itself has failed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is a small electrical component, straightforward for a service technician to change.
