Tecumseh K71-115 Relay Kit

The Tecumseh K71-115 Relay Kit is a critical service component designed for high-performance Tecumseh compressor applications. This replacement potential relay is engineered to manage the high starting torque requirements of single-phase motors, ensuring reliable separation of the start winding once the motor reaches operational speed. Built to handle the rigorous duty cycles of commercial refrigeration systems, the K71-115 provides a precise electromagnetic response to back-EMF, protecting the compressor from overheating and potential winding failure. This kit is essential for maintaining the efficient operation of HVACR equipment, particularly in medium to high back pressure (MBP/HBP) systems where starting loads are significant. Using an OEM Tecumseh start relay ensures electrical compatibility with existing capacitor configurations, reducing the risk of premature component failure. For field technicians, this electrical start kit offers a direct-fit solution that streamlines the troubleshooting and repair of intermittent startup issues in condensing units and self-contained refrigeration fixtures.

• Optimized Starting Torque: Engineered to provide the necessary electrical surge for heavy-load compressor startups.
• OEM Compatibility: Precision-matched for specific Tecumseh refrigeration compressors to ensure seamless electrical integration.
• High Thermal Stability: Constructed with materials capable of withstanding the heat cycles common in commercial mechanical rooms.
• Direct Field Replacement: Simplifies the retrofit process by matching exact mounting points and terminal configurations for various commercial HVAC maintenance tasks.

What are the symptoms of a failing K71-115 relay?
Common indicators include the compressor humming but failing to start, frequent tripping of the thermal overload protector, or the start capacitor showing signs of swelling due to the relay points sticking.

Can this relay be used on non-Tecumseh compressors?
While functionally similar to other potential relays, the K71-115 is calibrated specifically for the electrical characteristics and pickup/drop-out voltages of Tecumseh motors. Verification of the compressor model number is recommended for proper relay kit troubleshooting.

Does this kit include a start capacitor?
The K71-115 is the relay component of the starting system. When replacing the relay following a motor failure or starting issue, it is best practice to also inspect and typically replace the start capacitor to ensure the entire start circuit is functioning within spec.
