Tecumseh K146-17 Start Capacitor
The Tecumseh K146-17 Start Capacitor is a dry electrolytic capacitor engineered for high-torque motor starting in commercial refrigeration and HVAC applications. Rated for 243-292 MFD (microfarads) at 110V/125V AC, this component provides the essential phase shift required to initiate the compressor motor under high head pressure. Built to withstand the rigorous cycling demands of Tecumseh hermetic compressors, its phenolic resin housing ensures thermal stability and moisture resistance in demanding mechanical room environments. For technicians performing compressor troubleshooting or capacitor replacement, verifying the microfarad range is critical to prevent start-winding overheating. This HCFC/HFC compatible electrical component features standard 1/4" quick-connect terminals for rapid installation, ensuring the PSC or CSIR motor reaches synchronous speed efficiently during the starting phase.
Technical Specifications & Benefits
- Capacitance Range: 243-292 MFD for high-starting torque.
- Voltage Rating: 110-125 VAC, ideal for standard 115V fractional horsepower applications.
- Construction: Non-polarized aluminum electrolytic design for intermittent duty.
- Compatibility: Direct OEM replacement for specific Tecumseh and Mars 11005 profiles.
- Performance: Increases starting torque to overcome high internal pressures during hot-start conditions.
Common Questions
What causes a 243-292 MFD capacitor to fail?
Failure is typically driven by excessive heat, high-cycling frequency, or a sticking potential relay that keeps the capacitor in the circuit too long, causing the electrolyte to vent.
Can I use a higher MFD rating than the K146-17?
It is standard practice to stay within the 243-292 microfarad range specified by the manufacturer; exceeding this can damage the start winding or lead to premature failure.
Is the Tecumseh K146-17 compatible with other motor brands?
Yes, provided the mfd rating and voltage rating meet or exceed the original motor requirements, this 110V start capacitor functions as a universal field replacement.
