Tecumseh K90-73 Overload

The Tecumseh K90-73 Overload is a critical hermetic component designed for precise motor protection in the TPA2411ZAA and TPA2414UDS compressor series. As a veteran-grade OEM replacement overload protector, this kit is engineered to sense excessive current draw and high internal temperatures, effectively breaking the circuit to prevent compressor motor burnout during a locked rotor condition or voltage fluctuation. For technicians managing refrigeration systems, the K90-73 ensures the electrical integrity of the system by providing a repeatable trip point that resets only once safe operating temperatures are met.

This Tecumseh compressor overload kit arrives with the necessary mounting hardware to facilitate a direct-fit installation on the hermetic terminal. With a rated RLA (Rated Load Amperage) and LRA (Locked Rotor Amperage) calibration specific to the TPA series, it acts as the primary hardware-based defense against thermal overload. Whether you are performing a reactive repair or a preventative maintenance overhaul, utilizing a genuine Tecumseh overload protector ensures that the system operates within its original engineering parameters, maintaining optimal thermal management for the compressor.

• Precise Current Sensing: Calibrated specifically for 115V TPA series compressors to prevent winding damage.
• Thermal Protection: Monitors the hermetic compressor temperature to avoid catastrophic motor failure.
• OEM Compatibility: Exact replacement for Tecumseh K90-73, ensuring proper fitment and terminal alignment.
• System Reliability: Defends against voltage spikes and mechanical failures that lead to high amperage draw.

Which compressor models are compatible with the K90-73?
This overload is primarily used for Tecumseh TPA2411ZAA and TPA2414UDS models. Always verify the RLA/LRA ratings on the compressor nameplate before installation.

What causes a K90-73 overload to trip repeatedly?
Frequent tripping usually indicates a failing start capacitor, a restricted capillary tube, or low voltage supplied to the compressor. Ensure the refrigeration system is operating within specified pressure ranges.

Can I use a universal overload instead of the K90-73?
While universal options exist, using a genuine K90-73 kit is recommended to match the specific trip-curve and thermal reset timing required for the TPA compressor’s internal protection.
