Tecumseh K71-17 Relay Kit
The Tecumseh K71-17 Relay Kit is a field-proven solution for restoring high-torque starting performance to hermetic compressors. This kit features a precision-engineered potential relay designed to drop the start capacitor out of the circuit once the motor reaches the required back EMF, preventing winding overheat. As a direct OEM replacement part, it ensures proper electrical sequencing for Tecumseh refrigeration units, maintaining the exact calibrated pick-up and drop-out voltages required for reliable operation in high-head pressure environments.
Built for the rigors of commercial refrigeration, the Tecumseh compressor relay components in this kit are housed in durable, heat-resistant casings. For technicians servicing legacy or current condensing units, the K71-17 provides an exact match to factory specifications, eliminating the guesswork associated with "one-size-fits-all" domestic hard-start substitutes. Whether you are performing a reactive HVAC compressor repair or a proactive electrical overhaul, this kit ensures the motor start winding is protected and the system resumes efficient duty cycles.
Key Benefits- Ensures accurate capacitor cutout to prevent start-winding burnout.
- Supports high-torque starting in systems with capillary tubes or expansion valves.
- Direct OEM technical match for Tecumseh compressors, ensuring exact voltage calibration.
- Rugged construction designed for high-ambient commercial refrigeration applications.
- Simplifies the compressor electrical troubleshooting process with pre-matched components.
Is the K71-17 a universal hard start kit?
No, this is a calibrated potential relay kit specifically engineered for Tecumseh compressors to match their unique electrical characteristics, unlike generic 3-wire kits.
How do I confirm if this relay is compatible with my compressor?
Verify the compressor model number on the nameplate. This kit is commonly used with specific high-back pressure (HBP) and low-back pressure (LBP) Tecumseh models.
What are the signs of a failing compressor relay?
Common indicators include the compressor "humming" but failing to start, repeated tripping of the overload protector, or visible scorching at the relay terminals.
