Product Overview
The Rheem 47-21711-04 is an automatic reset limit switch designed for use in heating systems. This safety component features a normally closed, single-pole single-throw (SPST) configuration and is engineered to protect your system by interrupting operation when temperatures exceed safe thresholds.
Temperature Specifications
This limit switch is rated at L200-20F, meaning it is designed to open (trip) at 200°F and automatically reset at 180°F. The 20°F differential between the trip and reset points ensures stable, reliable cycling without short-cycling the connected equipment.
Key Features
- Auto Reset: Automatically resets once the temperature drops back to 180°F, eliminating the need for manual intervention
- Normally Closed (NC): Circuit remains closed under normal operating conditions and opens upon reaching the high-limit temperature of 200°F
- SPST Configuration: Single-pole single-throw design for straightforward integration into control circuits
- 7" Insert Length: Designed to fit into standard sensing element wells for accurate temperature detection
- OEM Rheem Part: Manufactured to Rheem's original equipment specifications for guaranteed compatibility and reliability
Compatibility & Application
As a genuine Rheem OEM replacement part, the 47-21711-04 is engineered for direct compatibility with applicable Rheem heating equipment. The 7" insert length ensures proper placement within the heat exchanger or plenum for accurate temperature sensing. Always verify compatibility with your specific unit model before installation.
Why Limit Switches Matter
Limit switches are a critical safety component in forced-air heating systems. They prevent overheating by shutting down the burner or blower when internal temperatures reach unsafe levels. Using a properly rated, manufacturer-approved replacement like this Rheem unit helps maintain system safety, efficiency, and longevity.
