Tecumseh K90-84 Overload Kit
The Tecumseh K90-84 Overload Kit is a crucial external protective component designed for high-side refrigeration and air conditioning systems. Engineered for seamless integration with Tecumseh hermetic compressors, this OEM replacement kit functions as a thermal and current-sensitive safety relay. By monitoring the compressor current draw and motor temperature, the internal contacts automatically open the circuit if parameters exceed safe operating limits, effectively mitigating the risk of compressor motor burnout and winding failure. For service technicians, ensuring the correct compressor overload relay is installed is the first line of defense against permanent mechanical damage. This kit is specifically calibrated for the AKA2415ZXA and AKA2415ZXD series, among other compatible models, providing the precise overload protection required for low back pressure (LBP) and high back pressure (HBP) applications. Its compact design allows for direct mounting to the compressor terminal, ensuring rapid response to localized heat buildup during locked rotor (LRA) conditions or high-ambient stress.
Key Benefits- Enhanced Thermal Protection: Actively monitors shell and winding temperatures to prevent localized hotspots and insulation degradation.
- OEM Compatibility: Designed primarily as a drop-in replacement for specific Tecumseh AKA and AE series compressors, ensuring verified trip curves.
- Hard-Start Resilience: Built to handle transient current spikes without nuisance tripping, maintaining system uptime in commercial environments.
- Failure Mitigation: Prevents catastrophic failure by interrupting the power supply during excessive current draw or condenser fan failure.
Is the K90-84 compatible with all Tecumseh models?
While the Tecumseh K90-84 Overload Kit is versatile, it is specifically calibrated for specific voltage and amperage ratings. Always verify your compressor model number against the HVAC part cross-reference data to ensure the trip points align with your unit's LRA and RLA specs.
What are the signs of a failing compressor overload?
Common symptoms include the compressor "cycling on protector," where the motor hums and then clicks off shortly after startup. If the internal heater is compromised or the contacts are pitted, it may fail to reset, resulting in an open circuit.
Does this kit include the terminal cover?
This is a standard overload replacement kit; check your existing assembly for the bale strap or terminal cover. Secure mounting is essential to ensure the thermal disc stays in constant contact with the compressor housing for accurate sensing.
