Tecumseh K90-28 Overload Kit
The Tecumseh K90-28 Overload Kit is a critical external compressor protection component engineered for high-performance hermetic systems. Designed to monitor the common winding of the motor, this kit utilizes a bimetallic thermal disc to sense excessive current draw or localized overheating. When temperatures exceed operational thresholds, the overload relay breaks the electrical circuit, preventing catastrophic coil burnout and permanent motor failure. This OEM-grade assembly is built specifically for Tecumseh refrigeration and air conditioning compressors, ensuring the response time and trip curve meet strict factory specifications.
Field installations of the Tecumseh K90-28 are standard in commercial walk-in coolers, residential heat pumps, and localized refrigeration units. By managing the amperage flow through the motor start and run windings, the kit mitigates the risks associated with locked rotor amps (LRA) and high head pressures. This is a vital service part for veteran technicians performing reactive maintenance or system overhauls where electrical integrity is paramount.
Key Benefits
- Precision Thermal Sensing: Employs a calibrated bimetal disc for accurate heat detection and circuit interruption.
- Universal System Compatibility: Optimized for various Tecumseh compressor models used in HVACR applications.
- Compressor Longevity: Prevents terminal venting and insulation breakdown by cutting power before damage occurs.
- OEM Reliability: Genuine manufacturer kit ensures proper fitment and performance without the variability of aftermarket parts.
Common Questions
How do I test the K90-28 with a multimeter?
Technicians should check for continuity across the terminals using an ohmmeter. If the component is cool but shows an open circuit (OL), the internal contacts are likely failed and the kit requires replacement.
Will this resolve a compressor that is "tripping on overload"?
While the kit provides protection, frequent tripping often indicates underlying issues such as a failing capacitor, restricted refrigerant flow, or high ambient temperatures. The K90-28 ensures the compressor remains safe while you diagnose the root cause.
Can I use this kit for different horsepowers?
Cross-reference the Tecumseh service guidebook and the specific compressor model number (e.g., HGA9468ZXD) to ensure the trip current and voltage ratings match your application.
