Tecumseh K90-36 Overload Kit
The Tecumseh K90-36 Overload Kit is a critical external motor protection component designed to safeguard reciprocating compressors from thermal damage and excessive current draw. As an essential part of the hermetic terminal assembly, this kit monitors the compressor’s winding temperature and amperage, providing a secondary line of defense against locked rotor conditions or phase loss. Engineered for high-stress refrigeration and air conditioning environments, the K90-36 overload protector ensures the electrical circuit opens before heat-induced insulation failure occurs, maintaining the integrity of the HVAC compressor motor during high ambient operation or system malfunctions.
For technicians servicing Tecumseh AJA5517EXV models or similar high-torque systems, this OEM replacement kit provides a direct fit to restore factory-spec safety parameters. The kit includes the Klixon overload and necessary mounting hardware for secured installation within the terminal cover. Utilizing bi-metal disc technology, the K90-36 offers precise trip curves and automatic reset functionality, minimizing downtime while preventing catastrophic compressor failure. Its compact design is optimized for heat transfer from the compressor housing, ensuring responsive protection against compressor overheating and electrical surges.
Key Benefits:- Precise Thermal Response: Uses calibrated thermal overload sensors to detect winding stress before permanent damage occurs.
- Optimized Compatibility: Specifically designed for Tecumseh refrigeration compressors, including 265V/60Hz/1Ph and 220-240V/50Hz applications.
- Enhanced System Safety: Prevents terminal venting and electrical fires by interrupting power during critical overcurrent events.
- Industrial-Grade Build: Engineered to withstand the frequent cycling and high temperatures found in commercial HVAC systems.
How do I verify if the K90-36 is the correct overload for my unit?
Contractors should match the part number against the Tecumseh Electrical Service Parts Guidebook using the compressor model and bill of materials (BOM). Compatibility is determined by the specific RLA (Rated Load Amperage) and LRA (Locked Rotor Amperage) ratings of the motor.
Can I use a universal overload instead of this OEM kit?
While universal options exist, the K90-36 is calibrated to the specific trip curves of compatible Tecumseh models. Using a non-OEM part may result in nuisance tripping or, more dangerously, failure to trip during a true overload condition.
What are the signs that an overload kit needs replacement?
If the compressor is "clicking" but failing to start, or if the overload protector is stuck in an open position (verified by a continuity test with a multimeter), the kit should be replaced immediately. Always check the run capacitor and start relay simultaneously to ensure the entire starting circuit is functional.
