Tecumseh K90-91 Overload Kit
The Tecumseh K90-91 Overload Kit is a critical electrical safety component designed for hermetic compressor protection in commercial refrigeration and HVAC systems. As a veteran technician knows, a faulty overload can lead to catastrophic motor failure; this kit serves as the primary line of defense against excessive current draw and thermal overload conditions. Engineered specifically for Tecumseh compressor motors, including common models like the AJA4492YXA and AJA4512AXD, the K90-91 monitors the common terminal to interrupt power before winding insulation degrades. This OEM replacement part is built to handle the rigorous duty cycles of industrial equipment, ensuring that your refrigeration compressor parts maintain peak reliability. Utilizing a precise bimetallic disc mechanism, it provides an automatic reset function that restores operation once safe temperatures are reached, reducing unnecessary downtime on the job site. When diagnosing a unit that "hums but won't start," verifying the continuity of this internal overload protector is a standard protocol for any pro.
Key Benefits for Contractors:- Precision Motor Protection: Actively monitors amperage and temperature to prevent compressor motor burnout.
- Broad Compatibility: Standard Tecumseh K90-91 specifications fit a wide range of AJA and AEA series compressors.
- Durable OEM Construction: Manufactured to original equipment standards for consistent trip points and HVAC system reliability.
- Simplified Installation: Designed for direct terminal mounting with standard hermetic terminal configurations.
- Reduced Callbacks: High-quality sensing elements prevent nuisance tripping while ensuring electrical overload safety.
How do I check if my K90-91 is defective?
Perform a continuity test with a multimeter across the terminals while the part is cool. A reading of infinity (O.L.) usually indicates a "tripped" or failed bimetallic disc that requires replacement.
Will this work with other compressor brands?
This kit is engineered specifically for Tecumseh's thermal curves. Always cross-reference your specific compressor model number rather than relying on visual similarity to ensure proper trip ratings.
Does this kit include the bale strap and cover?
This is the electrical overload component. While it integrates with existing hardware, always inspect your terminal cover and bale strap for signs of arcing or heat damage during replacement.
