10 Pack TEMCo 161-193 uF 220-250V AC Motor Start Capacitors - HVAC

In this review of the 10 Pack TEMCo 161-193 uF motor start capacitors, the bottom line is simple: these are an economical, direct replacement option for technicians and DIYers who need reliable starting torque for single phase motors in HVAC, compressors, and pumps. The single biggest reason to buy is value for money: you get ten PCB-free, UL rated, electrolytic oil filled units that match typical OEM starting specs and are housed in a rugged phenolic case, making them a practical choice when multiple replacements or spares are needed.

Key Features

• Capacitance: The 161-193 uF range delivers the high starting pulse most single phase motors require for a reliable start under load.
• Voltage Rating: Rated at 220-250 VAC, these capacitors are suitable for common residential and light commercial 220-250V single phase systems.
• Temperature Range: With an operating range from -40 C to +65 C, the units tolerate a wide span of environmental conditions typical in HVAC and outdoor compressor enclosures.
• Construction: Electrolytic oil filled and housed in a rugged phenolic resin case, they provide physical protection and straightforward mounting for replacement tasks.
• Terminals and Fit: Standard 1/4' quick disconnect terminals and compact dimensions make these capacitors easy to install in OEM motor housings and control compartments.
• Safety and Warranty: All units are PCB-free, UL rated E492933, and covered by a 5 year warranty, offering additional assurance for prolonged use.

Who It's For

These capacitors are best for HVAC technicians, maintenance crews, electricians, and skilled DIYers who routinely service single phase motors in air handlers, condensers, compressors, and pumps. The 10 pack format is particularly useful for shops that need spares or for projects replacing multiple units at once.

Those who need an exact physical match to an unusually large OEM capacitor or who are concerned about long-term durability under extreme continuous duty should verify dimensions and consider sourcing a single OEM-specified replacement; some customers reported size differences and a few isolated durability issues after installation.

Pros & Cons

Pros

• Good value for money when replacing multiple start capacitors or stocking spares.
• UL rated and PCB-free construction reduces hazardous material concerns and meets common safety expectations.
• Compact, rugged phenolic case and 1/4' quick disconnect terminals make installation straightforward.
• Wide operating temperature range suits many HVAC and compressor environments.

Cons

• Physically smaller than some OEM parts, so confirm dimensions before replacing an original capacitor.
• While most customers report reliable function, there are a few reports of premature failure under real-world stress, so check installation and operating conditions.

Frequently Asked Questions

Are these capacitors safe for HVAC systems?
Yes, they are PCB-free and UL rated E492933, making them appropriate for typical HVAC and compressor replacement tasks when installed correctly.

Will these fit my existing motor?
They use standard 1/4 in quick disconnect terminals and compact dimensions, but confirm the 1.81 in diameter and 3.37 in height match your OEM space before replacing.

What should I do if a capacitor fails early?
Check installation polarity and mounting, ensure the motor is not subject to overcurrent conditions, and use the 5 year warranty if the unit fails under normal use.
