Tecumseh K71-42 Relay Kit
The Tecumseh K71-42 Relay Kit is a critical electrical component engineered for precise motor starting and compressor protection in refrigeration and air conditioning systems. This genuine OEM kit features a high-reliability potential relay designed for single-phase HVACR compressors where high starting torque is required. As a technician, you know that consistent voltage sensing is vital to disengaging the start capacitor once the motor reaches sufficient speed; the K71-42 ensures this transition occurs without arcing or premature contact wear. This compressor start relay is compatible with various Tecumseh AK and AJ series models, serving as a direct replacement for legacy part numbers. By maintaining the correct back EMF sensing parameters, this kit prevents motor winding overheating and extends the service life of the hermetic assembly. Using this field-ready Tecumseh start kit ensures that repairs meet original factory specifications, maintaining system efficiency and operational stability in demanding commercial or residential cooling applications.
Key Technical Benefits
- Optimized Starting Torque: Built to handle the high-current demands of commercial refrigeration compressors during the initial startup phase.
- Precision Voltage Sensing: Ensures the start circuit is disconnected at the exact pick-up voltage to protect the start windings.
- OEM Compatibility: Precision-fit for Tecumseh systems, eliminating the need for field modifications or bracket adjustments.
- Industrial Grade Contacts: Engineered for thousands of cycles under heavy electrical load without welding or carbon buildup.
Common Questions
- What causes a relay kit to fail? Frequent short-cycling or incorrect capacitor sizing often leads to contact pitted or coil failure in the relay.
- Is the K71-42 compatible with non-Tecumseh compressors? While it follows standard electrical logic, always verify the pick-up and drop-out voltage ratings before attempting cross-brand installation.
- Does this include the start capacitor? This kit specifically focuses on the relay and required mounting hardware; verify your capacitor capacitance and voltage ratings separately.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
