Tecumseh K90-29 Overload Kit
The Tecumseh K90-29 Overload Kit is a critical electrical safety component engineered for hermetic compressor motor protection in commercial and residential refrigeration applications. Designed specifically for high-torque models such as the AJA4461AXA compressor, this kit functions as a line-break thermal protector, proactively sensing excessive amperage and heat build-up. By interrupting the power supply before the windings reach critical temperatures, the Tecumseh K90-29 prevents terminal venting and catastrophic motor failure. As a genuine HVAC replacement part, this kit includes the necessary overload relay housing and mounting hardware to ensure a secure, vibration-resistant fit within the terminal box. For technicians performing compressor troubleshooting and repair, implementing an OEM-spec overload is non-negotiable for maintaining system integrity and operational longevity. Relying on precise trip curves, this overload protector maintains efficiency in 115V/60Hz/1Ph systems, ensuring the unit operates within safe electrical parameters regardless of ambient fluctuations.
Key Benefits- Engineered Protection: Specifically calibrated to prevent motor burnout by cutting power during locked rotor or over-current conditions.
- OEM Compatibility: Precision-fit for the Tecumseh AJA4461AXA, ensuring the trip curve aligns perfectly with the motor's thermal requirements.
- Optimized Performance: Facilitates reliable cycling and reduces the risk of nuisance tripping common with universal, non-OEM components.
- Complete Replacement: Includes all essential hardware for a direct swap, streamlining service calls and reducing field labor.
When should I replace the K90-29 overload instead of the entire compressor?
If the compressor is electrically sound but nuisance tripping or failing to start, the overload protector may be fatigued or damaged. High-resistance contacts in a worn overload can cause voltage drops that mimic a failing motor.
Is the K90-29 compatible with 230V models?
No, this kit is specifically designed for 115V single-phase units like the AJA4461AXA. Always verify your compressor's nameplate voltage before installation to ensure the thermal overload relay trip ratings match the application.
Does this kit include a start capacitor?
This is a dedicated compressor overload kit. While it is a primary safety component for the electrical circuit, start components like capacitors or relays are sold separately depending on the specific starting torque requirements of your system.
