Tecumseh K90-27 Relay
The Tecumseh K90-27 Relay is a mission-critical overload protector relay designed for high-performance hermetic compressors, specifically the AKA4476YXA and AKA4482YXA models. As an OEM-spec compressor start relay and thermal protector, this component monitors current flow to prevent motor burnout during locked-rotor conditions or excessive thermal spikes. For technicians servicing 115V or 208-230V systems, this overload protector relay ensures electrical integrity by disconnecting power the moment predefined trip thresholds are exceeded, protecting the start windings from permanent damage.
Built for reliability in commercial refrigeration and HVAC applications, the Tecumseh K90-27 features an electromechanical design with a manual or automatic reset function tailored for hermetic compressor protection. Its compact footprint allows for seamless integration within standard terminal box configurations. When replacing a failed HVAC compressor relay, using the original K90-27 ensures calibrated response times that match the compressor's thermal curve, maintaining system efficiency without the risks associated with generic aftermarket parts.
Key Benefits:- Precise Thermal Response: Engineered to match the heat-dissipation rates of specific Tecumseh AKA series compressors.
- Enhanced Motor Longevity: Prevents catastrophic winding failure by interrupting the circuit during high amperage or stalled rotor events.
- OEM Compatibility: Guaranteed fit for AKA4476YXA and AKA4482YXA models, ensuring wiring continuity and proper mounting.
- Industrial-Grade Build: Robust contact points designed to withstand the high inrush currents typical of commercial start cycles.
- How do I know if my K90-27 relay has failed? Typically, if the compressor is "clicking" but failing to start, or if there is no continuity across the protector terminals while cooled, the relay has likely tripped or failed open.
- Can this relay be used on other compressor brands? While technically possible if specifications align, we recommend sticking to Tecumseh-specified compressor parts to ensure the trip curve protects the specific winding resistance of your motor.
- Does this include the start capacitor? No, the K90-27 is the overload protector relay only; start capacitors must be sourced separately based on the compressor's MFD requirements.
