Tecumseh K90-88 Overload Kit
The Tecumseh K90-88 Overload Kit is a critical external protection component designed for specific Tecumseh fractional horsepower compressors. This OEM compressor overload functions as a line-break safety device, monitoring both thermal rise and current draw to prevent motor burnout during locked rotor conditions or system overloads. Engineering tolerances are strictly calibrated to match the trip curves of compatible refrigeration compressor parts, ensuring the unit cycles off before winding insulation reaches critical failure temperatures. When performing a compressor startup troubleshooting procedure, replacing a weak or failed overload with the exact K90-88 replacement is essential for maintaining the operational integrity of the hermetic circuit. This kit includes the necessary mounting hardware to ensure a secure thermal connection against the compressor housing, providing accurate sensing for high-side pressure spikes or restricted airflow scenarios typical in commercial HVACR maintenance.
Key Technical Benefits- Precise Thermal Calibration: Engineered to specific trip points that protect Tecumseh compressor motor windings from excessive amperage.
- OEM Compatibility: Guaranteed fitment for specific K-series and earlier small-displacement models, eliminating the risks associated with universal aftermarket components.
- Snap-Action Response: Features a bimetallic disc designed for rapid circuit interruption and reliable reset cycles under demanding field conditions.
- Simplified Installation: Standard terminal configurations allow for direct integration into existing wiring harnesses for faster service calls.
How do I verify if the Tecumseh K90-88 is the correct overload for my specific model?
Compatibility is determined by the compressor's model number and the specific BOM (Bill of Materials). Always cross-reference the stamped part number on the original overload housing with the Tecumseh K90-88 specifications to ensure the trip curve matches the motor's amperage rating.
What are the symptoms of a failing compressor overload?
Common signs include the compressor "clicking" on and off without starting, high amperage readings followed by an immediate circuit break, or the compressor body being excessively hot to the touch while the motor fails to engage.
Can I use a universal overload instead of the K90-88 kit?
While universal options exist, they often lack the precise trip-time characteristics required for localized protection. Using the OEM Tecumseh K90-88 ensures the protection remains within the manufacturer’s specified safety envelope for that specific displacement and motor type.
