Product Overview
The Rheem 47-21777-04 is a defrost sensor limit switch designed for reliable temperature-based control in HVAC and refrigeration applications. This auto-reset switch provides automatic operation without the need for manual intervention after a trip event.
Key Specifications
- Manufacturer: Rheem
- Part Number: 47-21777-04
- Function: Defrost Sensor (L50-22F)
- Switch Type: SPST (Single Pole, Single Throw)
- Reset Type: Auto Reset
- Action: Open on Rise
- Close Temperature: 28°F
- Open Temperature: 50°F
How It Works
This limit switch operates on temperature rise, meaning the switch opens at 50°F to interrupt the circuit and closes at 28°F to restore the circuit. This temperature differential allows the switch to accurately monitor and respond to defrost cycle conditions, ensuring the system operates within its intended temperature range.
Auto Reset Functionality
Equipped with an automatic reset feature, this limit switch will reset itself once temperatures return to the closing threshold of 28°F. This eliminates the need for manual reset procedures and supports continuous, uninterrupted system operation.
Compatibility
This is a genuine Rheem OEM replacement part, engineered to meet the exact specifications of the original component. It is designed for use in Rheem systems where defrost cycle temperature sensing and control are required.
