Reznor 193813 Pressure Switch
The Reznor 193813 Pressure Switch is a critical safety component designed for precise combustion air monitoring in high-efficiency heating systems. This 0.8" WC SPDT Pressure Switch (Single Pole Double Throw) features dual 1/4" barb connections, allowing for accurate differential pressure sensing across the heat exchanger. As a genuine Reznor OEM replacement part, it is the direct substitute for obsolete switches in (H)SC, (H)RP, and RPB series units (sizes 100-225) equipped with AG39 or AG40 options. Veteran technicians recognize this as the reliable fix for induction motor proofing issues, ensuring the burner only fires when proper drafting is established. This Reznor HVAC replacement part is engineered for industrial and commercial environments where airflow regulation is paramount for system integrity. Proper installation helps prevent short-cycling and ensures the unit operates within manufacturer-specified pressure parameters.
Key Benefits:
- Direct OEM Compatibility: Specifically engineered for Reznor SC and RP series furnaces, replacing manual model FS6788-3007 and obsolete P/N 175863.
- Differential Pressure Accuracy: Factory-set at 0.8" Water Column to maintain strict safety thresholds for flue gas venting.
- Versatile Wiring: The SPDT configuration supports common (C), normally-open (NO), and normally-closed (NC) terminal configurations for various control logic boards.
- Robust Hose Integration: The dual 1/4" barb fittings provide a secure, leak-proof seal with silicone sensing tubing for consistent vacuum or pressure signals.
- Enhanced Safety: Built to sense and respond to subtle pressure changes, protecting the heat exchanger from overheating due to venting obstructions.
Common Questions:
How do I know if my Reznor 193813 is failing?
Technicians typically check for an open circuit at the switch during the inducer motor's run cycle. If the manometer shows 0.8" WC or higher at the ports but the SPDT switch does not close to prove the draft, the internal diaphragm or contacts have likely failed.
Will this switch work on units manufactured before 1991?
No. For Reznor RP and RPV series units built prior to 1991, you must use Kit P/N 93033. This 193813 Pressure Switch is designed for later series models and includes the necessary 1/4" and 3/16" quick-connect terminals to meet modern ANSI/CSA standards.
Why does the kit include extra wire terminals?
Reznor updated their terminal sizes to meet specific safety requirements. If your existing wiring uses smaller connectors, the included replacement terminals allow you to update the harness for a secure fit on the new 193813 switch.
