Tecumseh 8300MRAC19 Overload
The Tecumseh 8300MRAC19 Overload is a precision-engineered thermal protector designed specifically for compressor motor protection in light commercial and residential refrigeration units. As a high-performance thermal overload relay, this component monitors both current draw and operational temperature to prevent winding failure during locked rotor or high-head pressure conditions. For a veteran technician, this is a standard compressor replacement part that offers an automatic reset capability, ensuring the circuit re-engages once safe operating temperatures are restored. It is crucial to verify that the MRA overload rating matches your compressor's LRA (Locked Rotor Amps) and RLA (Rated Load Amps) to ensure timely tripping without nuisance service calls.
Key Benefits
- Compatible with a wide range of Tecumseh hermetic compressors found in HVACR systems.
- Provides essential overcurrent protection to extend the service life of the motor windings.
- Robust, compact construction facilitates installation within standard hermetic terminal housings.
- Integrated thermal interrupter mechanism reacts quickly to excessive heat buildup.
- Optimized for HVAC mechanical systems requiring reliable, field-proven electrical safety components.
Common Questions
How do I test the Tecumseh 8300MRAC19 for failure?
Using a calibrated multimeter, check for continuity across the terminals. If the component is at room temperature and shows an open circuit (OL), the internal bimetallic strip or heater is likely compromised and requires replacement.
Can I use this overload with a start capacitor?
This overload protector is specifically designed to work in conjunction with the compressor's relay and capacitor setup. Always consult the compressor wiring diagram to ensure the overload is wired in series with the common terminal to provide full protection.
What causes this part to trip frequently?
Frequent tripping usually indicates a high-amp draw issue, such as a failing run capacitor, a restricted capillary tube, or non-condensables in the system. Replacing the overload without diagnosing these root causes may lead to further system damage.
