Tecumseh K146-25 Start Capacitor

For service technicians managing high-torque compressor restarts, the Tecumseh K146-25 Start Capacitor is the direct replacement engineered to address voltage drop and heavy starting loads. This 161-193 MFD start capacitor serves as the current HVAC OEM replacement part for the legacy 85PS165C96 and 85PS165C98 models, facilitating a seamless transition during maintenance or repairs. Designed for 165 VAC applications, this Tecumseh compressor start capacitor provides the critical phase-shift required to energize the start windings of reciprocating compressors used in commercial refrigeration and air conditioning systems. The robust construction ensures it handles the high inrush current typical of CSIR (Capacitor Start Induction Run) and CSCR motor configurations. By upgrading to the K146-25, contractors provide the necessary starting torque to prevent motor stalling and reduce heat buildup in the windings, extending the operational life of the system without compromising performance in demanding environments.

• Precise Capacitance Range: Features 161-193 microfarads (MFD) to ensure consistent starting torque for medium to high-back pressure compressors.
• Direct OEM Compatibility: Verified as the official update for Tecumseh part number 85PS165C96, ensuring exact physical and electrical fitment.
• Industrial Build Quality: Encased in a durable, moisture-resistant housing designed for 50/60Hz cycles in commercial HVACR systems.
• Enhanced Motor Protection: Minimizes the duration of high-amp draw sequences, protecting internal compressor components from mechanical stress.

What is the difference between the K146-25 and the older 85PS165C96?
The K146-25 is the manufacturer-designated superseding part. It matches the technical profile and 161-193 MFD rating of the 85PS165C96 while incorporating updated materials for better thermal stability.

Can I use this capacitor on a different brand's compressor?
While this is a Tecumseh start capacitor, it can be used on any compressor requiring a 161-193 MFD 165V capacitor, provided the physical dimensions and connection terminals are compatible with your existing bracketry.

How do I know if my start capacitor has failed?
Technicians should look for physical bulging at the top of the casing or use a multimeter to check if the capacitance is outside the 161-193 MFD tolerance range. A failure often results in a humming compressor that fails to turn over.
