Raypak 006737F Pressure Switch

For contractors servicing Raypak units, the Raypak 006737F Pressure Switch is the standard OEM solution for resolving flow-related ignition failures. This SPST (Single Pole Single Throw) direct-mount switch is factory-calibrated at a 1.75 PSI activation point, providing the critical pressure differential sensing required to engage the control board and burner tray. Featuring a 1/4" barb connection, this switch integrates seamlessly into the water circuit of specific Raypak Digital Atmospheric and Low NOx pool heaters, including the R106A, R156A, R206A, R266A, R336A, and R406A series. Operating as a normally open safety device, it ensures the heater remains in a safe lockout state unless sufficient circulation is detected. Professional installation ensures high-performance switching and prevents the common "PRS" or "Service" fault codes encountered when high-limit or flow circuits are compromised.

• OEM Precision: Direct replacement part ensures exact 1.75 PSI calibration for consistent safety circuit closure.
• Enhanced Compatibility: Engineered specifically for the Raypak 206A-406A and 207A-407A heater families.
• Durable Construction: Features a rugged housing and a standard 1/4" barbed fitting for reliable hose attachment under thermal stress.
• Contractor Reliability: Replaces faulty or corroded switches to eliminate erratic heater cycling and low-flow diagnostic errors.

• Why is my heater showing a "PRS" or "Low Flow" fault? This often indicates that the pressure switch is not closing. Verify that your pump is primed and the filter is clean. If pressure is adequate but the circuit stays open, the 006737F likely requires replacement.
• Can I use an adjustable switch instead of the 006737F? While adjustable switches exist, this OEM part is factory-set to 1.75 PSI to meet the specific safety requirements of Raypak heat exchangers.
• Does this switch work on both Natural Gas and Propane models? Yes, the pressure switch monitors water flow and is independent of the fuel type used by the burner assembly.
