Rheem-Ruud 47-23117-01 Limit Switch

The Rheem-Ruud 47-23117-01 Limit Switch is a critical safety component designed for precise thermal monitoring in HVAC air handlers and heating systems. This OEM replacement part features a Single Pole Single Throw (SPST), normally closed configuration, making it a reliable choice for maintaining safe operating temperatures. It is engineered with a fixed open temperature of 80 degrees F and a fixed close temperature of 70 degrees F, ensuring the system interrupts power if the return air or internal housing exceeds safe limits. The gray color coded housing allows for quick identification during field service, and the auto reset functionality ensures the system resumes operation once temperatures normalize within the 10-degree differential. Built for high-amperage applications, it supports up to 25 Amps at 230VAC and utilizes standard 1/4 inch quick connect terminals for a secure, low-resistance electrical connection. This surface mount limit switch is a standard-stock item for technicians servicing Rheem, Ruud, and WeatherKing equipment.

• OEM Compatibility: Exact drop-in replacement for Rheem-Ruud part number 47-23117-01, maintaining original factory specifications.
• Enhanced Safety: The normally closed switch provides fail-safe protection by opening the circuit at 80°F to prevent equipment overheating.
• Automatic Recovery: Features an auto reset mechanism that closes the circuit at 70°F, reducing unnecessary service calls for manual resets.
• Heavy-Duty Contacts: Rated for 25 Amps, providing durability in high-demand HVAC 230V systems.
• Simplified Installation: The flangeless surface mount design and 1/4" terminals streamline the swap-out process for contractors.

What does the gray color code signify on this switch?
In the Rheem-Ruud parts ecosystem, the gray code specifically identifies the 70°F/80°F temperature setpoints, allowing for rapid visual verification without pulling the part for bench testing.

Can I use this limit switch on a furnace rollout application?
This specific switch is designed for low-temperature limits, typically in air handlers. Always verify the temperature ratings on your existing part; using an 80°F switch in a high-heat furnace application will cause premature tripping.

Is this an automatic or manual reset limit?
This is an auto reset limit switch. It will automatically re-close once the temperature drops to 70°F. If your system requires a manual intervention for safety reasons, this may not be the correct component.
