Tecumseh K90-12 Overload Kit
The Tecumseh K90-12 Overload Kit is a critical external protection component designed for specific Tecumseh hermetic compressors. As a technician-grade compressor motor protector, this kit monitors current draw and internal temperatures to prevent winding failure during locked rotor or thermal overload conditions. The K90-12 is engineered for precise trip curves, ensuring the compressor stays within its safe operating envelope without nuisance tripping. When replacing a failed Tecumseh overload relay, using the exact OEM replacement kit is vital for maintaining the calibrated response time required to protect the motor insulation from degradation. This HVAC compressor protection kit includes the necessary thermal overload device and mounting hardware compatible with various high-side and low-side refrigeration applications. Integrating a genuine Tecumseh K90-12 ensures the electrical safety circuit remains intact, preventing costly premature compressor replacements in commercial and residential systems.
Key Benefits- OEM Precision: Calibrated specifically for Tecumseh compressor motor windings to ensure accurate thermal protection.
- Optimized Trip Curves: Prevents motor burnout by interrupting the circuit before winding temperatures exceed design limits.
- Durable Construction: Built to withstand the high-temperature environment of the compressor terminal box.
- Simplified Installation: Standard configuration allows for direct replacement of existing thermal protectors in HVAC electrical systems.
Is the Tecumseh K90-12 interchangeable with universal overloads?
While universal components exist, original Tecumseh refrigeration parts like the K90-12 are specifically matched to the compressor's amperage and temperature profile, offering more reliable protection than generic alternatives.
What causes a K90-12 overload to trip frequently?
Frequent tripping usually indicates a high amp draw from a failing start capacitor, a restricted capillary tube, or non-condensables in the system causing high head pressure.
How do I verify if my compressor needs a K90-12?
Check the compressor nameplate data or service manual. This Tecumseh overload replacement is typically used on specific fractional horsepower units where external motor protection is required.
