Tecumseh K71-02 Relay

The Tecumseh K71-02 Relay is an essential OEM potential relay designed for high-starting torque applications in refrigeration and air conditioning systems. This genuine Tecumseh compressor part is engineered to disconnect the start capacitor from the circuit once the motor reaches a specific voltage threshold, ensuring reliable operation of HVAC start components. Built for durability in demanding environments, the K71-02 provides precise switching to prevent motor burnout and optimize compressor longevity. Whether you are performing a Tecumseh relay replacement or troubleshooting a refrigeration start kit, this component ensures the back-EMF is accurately monitored for consistent contact opening. Its robust construction handles the high inductive loads characteristic of commercial refrigeration compressors, maintaining system efficiency and preventing unnecessary downtime for your clients.

• Precise Voltage Sensing: Optimized to drop out the start capacitor at specified pick-up and drop-out voltages to protect the winding.
• High-Torque Support: Specifically designed for commercial refrigeration relays requiring reliable starting power under load.
• OEM Compatibility: Ensures seamless integration with Tecumseh compressor models, eliminating the variables associated with universal aftermarket parts.
• Heavy-Duty Contacts: Engineered to withstand repeated cycling without pitting or welding in high-amperage applications.

How do I verify the correct wiring for the Tecumseh K71-02?
Ensure you follow the terminal markings (usually 1, 2, and 5) to align with the start capacitor, run winding, and common line. Refer to the specific compressor wiring diagram for terminal orientation.

Can this relay be used as a substitute for other K71 series parts?
While some relays share footprints, the pick-up and drop-out voltages are application-specific. Always match the K71-02 technical specifications with your compressor's requirements.

What are the signs of a failing potential relay?
Common indicators include the compressor failing to start, the start capacitor overheating or venting, or the compressor cycling on the thermal overload protector due to the start winding staying energized too long.
