Rheem-Ruud 47-23113-01 Limit Switch

The Rheem-Ruud 47-23113-01 Limit Switch is a critical safety component designed for precise thermal regulation in gas furnaces and air handlers. This SPST normally closed switch features a 180-degree F fixed open temperature and a 150-degree F fixed close temperature, ensuring the system shuts down immediately if the heat exchanger exceeds safe operating limits. Engineered for high-cycle reliability, the 47-23113-01 is green color-coded for rapid identification during field diagnostics and features an auto-reset mechanism that restores circuit continuity once ambient temperatures stabilize. This genuine OEM furnace high limit switch is built for direct compatibility with Rheem, Ruud, and WeatherKing equipment, preventing nuisance trips while providing robust protection against overheating conditions. For contractors, this limit control replacement ensures factory-spec performance and simplifies troubleshooting in high-static environments where thermal oversight is paramount.

• Precise Thermal Calibration: Fixed 180°F trip point prevents heat exchanger damage and ensures HVAC safety sensor compliance.
• Automatic Reset Logic: Eliminates manual intervention after cooling, reducing unnecessary service calls for Rheem furnace limit switch trips.
• OEM Standards: Direct-fit 47-23113-01 replacement ensures terminal alignment and bracket spacing matches factory mounting holes.
• Color-Coded Identification: Green coding allows for fast verification of the 180-degree limit switch specifications in the field.
• Durable SPST Construction: Designed to handle high-amperage inducer and blower circuits without premature contact pitting.

What causes a Rheem limit switch to trip repeatedly?
Frequent tripping is usually indicative of restricted airflow, often caused by a dirty filter, blocked secondary heat exchanger, or an undersized duct system. Verify static pressure before replacing the switch.

Is the 47-23113-01 compatible with other brands?
While this is a Rheem-Ruud replacement part, it can function in other systems if the 180°F open/150°F close specifications and mounting footprint match. Always refer to the original manufacturer's parts list.

Does the green color coding matter?
Yes. In the Rheem-Ruud parts ecosystem, the color code identifies the specific temperature range. Installing a switch with the wrong color code can lead to unsafe operation or premature system cycling.
