The Rheem SP20732 is a genuine Rheem water heater pressure switch. On a power-vented or direct-vent gas water heater, the pressure switch senses the draft produced by the blower and closes to prove that combustion air and venting are flowing before the control allows the burner to ignite. If the switch does not close, the heater will not fire.
A pressure switch that fails to close, or that trips during operation, often points to a blocked vent, a failed blower or a cracked hose rather than the switch itself, so inspect the venting when replacing. Confirm the part number on the existing switch before ordering.
