Tecumseh K90-45 Overload Kit

The Tecumseh K90-45 Overload Kit is a critical electrical protection component designed specifically for hermetic compressors. As an OEM Tecumseh replacement part, this kit integrates a calibrated compressor overload protector to monitor motor temperature and current draw, preventing terminal venting and winding failure during locked rotor or high-head pressure conditions. This K90-45 thermal protector provides a precise trip curve, ensuring that the compressor is de-energized before permanent damage occurs from localized overheating or phase imbalance. For technicians performing hermetic compressor electrical repair, using this HVAC compressor protection kit ensures that the motor remains within its safe operating envelope while maintaining the integrity of the original system design.

Key Benefits

• Ensures accurate thermal protection against winding burnout and excessive amperage.
• Includes the necessary specialized leads and mounting hardware for a secure HVAC electrical component installation.
• Maintains OEM specification compliance to prevent nuisance tripping and premature motor failure.
• Protects the hermetic terminal from potential arcing and grounding issues during electrical faults.

Common Questions

Which compressor models are compatible with the K90-45?
The K90-45 is cross-referenced for several high-efficiency Tecumseh reciprocating and rotary models. Always verify your compressor model number and voltage against the K90-45 trip specifications to ensure proper protection.

Does this kit include more than just the protector?
Yes, it is a complete hermetic overload assembly that includes the protector, the necessary electrical wires, and the specific mounting spring or clip intended for your unit.

When should I replace my existing overload?
If you encounter a compressor that is tripping on internal overload or shows continuity issues across the protector terminals, a direct replacement is required to restore safe system operation.
