Tecumseh K146-28 Start Capacitor
The Tecumseh K146-28 Start Capacitor is a high-duty cycle electrical component designed to provide the secondary torque necessary for high-starting torque (HST) compressors to overcome initial inertia. Rated for 165V with a capacitance range of 270-324 MFD, this electrolytic start capacitor is an essential replacement part for commercial refrigeration units and condensing unit motor starting applications. Engineered for compatibility with dedicated HVAC compressor start kits and potential relays, it ensures the start winding is energized only for the fraction of a second required to reach operational speed, preventing unnecessary heat buildup. For technicians servicing systems with non-bleed expansion valves or high-head pressure startup conditions, the K146-28 offers the precise microfarad rating required to restore factory-spec performance. This cylindrical, black-cased capacitor is built to withstand rigorous industrial environments where reliable motor starting torque is critical for system longevity.
Key Benefits
- Optimized Starting Torque: Provides the 270-324 MFD boost required for heavy-duty Tecumseh refrigeration compressors and HVAC motors.
- Broad Compatibility: Standardized 165V rating makes it a versatile fit for various industrial machinery start kits and motor applications.
- Protects Compressor Windings: Ensures rapid transition to run cycles, reducing the high-amperage stress that causes compressor motor burnout.
- Durable Construction: High-quality electrolytic design helps maintain capacitance stability under typical electrical vault operating temperatures.
Common Questions
What causes a start capacitor like the K146-28 to fail?
Failure is often caused by excessive heat, voltage spikes, or a faulty potential relay that keeps the capacitor in the circuit too long. If you notice a bulging top or "mushroomed" casing, the dielectric fluid has likely expanded due to overheating.
Can I use a capacitor with a higher MFD rating?
It is critical to match the 270-324 MFD range specified by the manufacturer. Using a higher microfarad rating than required can lead to excessive current on the start winding, potentially damaging the motor.
Why is my compressor humming but not starting?
A humming compressor that trips the breaker suggests the motor cannot overcome the pressure imbalance. Replacing a weakened or open-circuit start capacitor is often the first step in troubleshooting these startup failures.
