Tecumseh K90-20 Overload
The Tecumseh K90-20 Overload is a critical compressor protection component designed to safeguard HVACR refrigeration systems against excessive current draw and high-temperature conditions. Engineering for Tecumseh hermetic compressors, this thermal overload switch utilizes a precise bimetallic disc to interrupt the electrical circuit when internal temperatures or amperage exceed safe operating limits. This prevents motor winding failure and ensures long-term operational reliability in commercial refrigeration applications. When diagnosing a compressor not starting or experiencing frequent overload tripping, verifying the thermal integrity of the K90-20 protector is a standard protocol for service technicians. This replacement part provides a direct-fit solution for maintaining the OEM specifications of the cooling circuit, ensuring the compressor operates within its designated thermal protection curve. Proper installation is essential to maintain BTU efficiency and prevent catastrophic hardware loss during high-ambient-load scenarios or power surges.
Key Benefits for Technicians:
- Precision Thermal Sensing: Responsive bimetallic technology ensures accurate trip-free operation under specific current loads.
- Direct OEM Compatibility: Specifically engineered for Tecumseh refrigeration units to ensure exact fitment and electrical alignment.
- System Longevity: Prevents compressor burnout by mitigating damage from locked rotor amps (LRA) or voltage drops.
- Field Service Efficiency: Simplifies troubleshooting and restores system operation without requiring extensive modifications.
Common Questions:
How do I test if the Tecumseh K90-20 is defective?
Using a multimeter, check for continuity across the terminals while the part is at room temperature. An open circuit during a "cool" state typically indicates a failed thermal overload protector that requires replacement.
Why does my compressor keep tripping the K90-20 overload?
Persistent tripping usually signals an underlying mechanical issue, such as a failing start capacitor, poor electrical connections, or the compressor motor drawing excessive amperage due to high head pressure.
Can I bypass the overload for testing purposes?
Bypassing a safety device is not recommended for permanent operation. While briefly jumping the component can confirm if the overload is the point of failure, the compressor should never be left running without thermal protection.
