Description
The Rheem-Ruud SP20317 is an OEM exhaust pressure switch engineered specifically for Rheem and Ruud heating systems. This critical safety component monitors exhaust gas pressure to confirm that the venting system is operating correctly before allowing the burner sequence to proceed, protecting both the equipment and occupants from unsafe combustion conditions.
How It Works
The exhaust pressure switch senses negative pressure created by the draft inducer motor. If adequate pressure is not detected — indicating a blocked flue, failed inducer, or venting problem — the switch remains open, preventing ignition and triggering a lockout condition. This safeguard helps prevent the buildup of harmful combustion gases inside the living space.

Why Choose OEM?
Using a genuine Rheem-Ruud replacement pressure switch ensures your system operates within factory-specified safety parameters. Aftermarket substitutes may not meet the exact pressure set points required by your unit, potentially leading to nuisance lockouts or, more critically, unsafe operation. Trust the OEM part for dependable performance and peace of mind.
