Tecumseh K71-43 Start Relay
The Tecumseh K71-43 Start Relay is a high-performance potential relay engineered for industrial and commercial refrigeration compressors. Designed to facilitate precise motor initiation, this OEM Tecumseh replacement part ensures the start winding is effectively disengaged once the motor reaches the required operational velocity. Rated for 208-230V single-phase applications, it is a critical component for CSIR (Capacitor Start Induction Run) and CSR (Capacitor Start Run) motor configurations, particularly in high starting torque scenarios like expansion valve systems where pressure equalization has not yet occurred. Built with durable housing to withstand the thermal rigors of rapid-cycling environments, the K71-43 relay prevents compressor overheating and premature component failure by maintaining strict electrical timing during the start-up phase. For field technicians, this relay serves as a direct drop-in replacement for the AKA2425ZXD compressor series and various ARGUS condensing units, providing consistent locked rotor amperage (LRA) management and ensuring system efficiency across R-404A and R-22 platforms.
Key Benefits- Universal Compatibility: Specifically calibrated for 208-230V Tecumseh compressors, including the AKA and ASHR series.
- Optimized Starting Torque: Designed to handle the high-load demands of commercial refrigeration and AC units.
- Enhanced Thermal Protection: Prevents motor winding burnout by ensuring accurate disengagement of the start capacitor.
- Contractor Grade Durability: Robust construction to reduce service callbacks and maintain NEMA-standard electrical performance.
- Is this relay compatible with solid-state alternatives? While some technicians use solid-state units for light-duty RSIR motors, the K71-43 is a potential relay required for high-torque applications. Replacing this with a PTC relay can lead to starting failures in systems that haven't equalized.
- What are the symptoms of a failing K71-43 relay? Common indicators include an audible buzzing without compressor engagement, frequent cycling on the internal overload, or a visible "start-stop" stuttering of the motor.
- Does this include the start capacitor? No, the K71-43 is the relay assembly only. It is recommended to inspect the K146-41 start capacitor when performing a relay replacement.
