Rheem-Ruud 47-23117-04 Limit Switch
The Rheem-Ruud 47-23117-04 Limit Switch is a critical safety component designed for precise thermal monitoring within HVAC furnace systems. This SPST normally closed switch features a white color-coded body for quick field identification and operates on an auto-reset mechanism, ensuring the circuit re-engages once temperatures stabilize. Engineered with a fixed 75-degree F open temperature and a 65-degree F close temperature, this general purpose limit switch prevents heat exchanger overheating by interrupting the burner circuit if airflow is restricted. This OEM replacement part is essential for maintaining the sequence of operation in Rheem and Ruud gas furnaces. Its robust construction ensures reliable cycling under high-limit conditions, making it a standard furnace high limit sensor for professional service calls. For technicians troubleshooting furnace limit switch tripping, this unit offers the exact tolerances required to restore laboratory-tested safety parameters without the drift common in universal aftermarket alternatives.
Key Benefits for Contractors:
- Fixed Thermal Calibration: Precise 75°F Open / 65°F Close settings eliminate the need for field adjustments.
- OEM Compatibility: Designed specifically as a direct-drop replacement for Rheem-Ruud gas furnace models.
- Auto-Reset Functionality: Automatically restores the electrical circuit once the plenum cools, reducing unnecessary manual resets.
- Integrated Safety: Detects overheating heat exchangers and restricted airflow to protect the primary equipment.
- Professional Grade: Built to withstand the high-cycle demands of residential and commercial heating applications.
Common Questions:
How do I identify a faulty furnace limit switch?
Technicians should check for continuity across the terminals when the furnace is cool. If the switch remains open at room temperature, or if the furnace blower runs continuously while the burners fail to ignite, the Rheem-Ruud 47-23117-04 likely requires replacement.
What causes a limit switch to trip repeatedly?
Repeated tripping is usually symptomatic of restricted airflow. Check for a dirty air filter, blocked return grilles, or a failing blower motor before replacing the sensor.
Is the white color coding significant?
Yes, the white body on this Ruud replacement part signifies specific temperature ratings. Always match the color code or the stamped temperature specs to ensure the HVAC safety switch meets the original equipment manufacturer's requirements.
