Raypak 006725F Limit

As a veteran HVACR technician, you know that keeping a Raypak Digital Pool Heater operational depends on high-precision safety controls. The Raypak 006725F is a genuine OEM replacement hi-limit switch designed specifically for surface mounting. Operating with a fixed 135F temperature rating, this auto reset thermostat serves as a critical safety barrier, preventing heat exchanger damage and system overheating. This specific limit features a silver button sensor with two spade terminals and a distinct red dot indicator for fast identification during field service. When these pool heater limit switches fail, you typically see HL1 error codes or complete system shut-downs; replacing with a genuine Raypak part ensures the unit maintains its factory-specified safety parameters. This surface-mount component includes the necessary mounting screws and fits a wide array of Raypak and Rheem models, providing a reliable fix for recurring high-limit trips in atmospheric and digital heaters.

Key Benefits:

• Direct OEM Compatibility: Engineered for Raypak R185A, R206A, R266A, R336A, and R406A models, as well as Versa and RP2100 series equipment.
• Automatic Reset Functionality: Eliminates the need for manual intervention by resetting once the surface temperature drops below the 135-degree threshold.
• Verified Safety Specs: Calibrated to trigger an electrical response at exactly 135°F to protect the heat exchanger and plastic headers.
• Standardized Fitment: Features standard spade wire connectors and includes mounting hardware for a rapid swap-out on the header surface.

Common Questions:

How do I know if the 006725F is the correct limit for my heater?
This 135F switch is identified by a silver button and a red dot on the surface. It is designed for heaters with plastic headers. If your unit utilizes ASME-certified cast iron headers, you may require the brass-bodied 600892B limit instead.

What causes this hi-limit switch to trip?
Tripping is usually caused by low water flow, a bypassed internal unitherm governor, or scale buildup inside the heat exchanger. If the switch trips frequently, verify the pump speed and check for internal obstructions before replacing the part.

Can I use a manual reset switch instead?
You should always replace components with the exact OEM specification. Swapping an auto-reset limit for a manual reset (or vice versa) can alter the safety sequence and diagnostic behavior of the digital control board.
