5 Pack TEMCo 324-389 uF 110-125V AC Motor Start Capacitor - Reliable

In this review of the 5 Pack TEMCo 324-389 uF motor start capacitor, the bottom line is simple: this set is best for technicians and DIYers who need reliable, OEM-style replacements for single phase motors and compressors. The most compelling reason to buy is consistency - five identical, PCB-free, electrolytic oil filled capacitors in rugged phenolic cases provide a straightforward swap for worn start caps on HVAC units, pumps, and compressors without fuss. Installation is simple thanks to standard 1/4' quick disconnect terminals and the units are UL rated for safe, repeatable service.

Key Features

• Capacitance: The 324-389 uF rating matches many OEM start capacitor requirements so it fits common single phase motor replacements.
• Voltage and Frequency: Rated 110-125 VAC at 50/60 Hz, the capacitor is suitable for typical residential and light commercial motor circuits.
• Durability: The electrolytic oil filled design in a rugged phenolic resin case helps the unit withstand repeated starts and rough service conditions.
• Temperature Range: Operating from -40 C to +65 C supports installations in cold basements or warmer mechanical rooms without performance loss.
• Installation Friendly: Standard 1/4' quick disconnect terminals make swaps fast and reduce installation errors for service technicians.
• Safety and Support: PCB-free construction and UL rating E492933 provide reassurance, and a 5 year warranty covers typical wear-out concerns.

Who It's For

This 5 pack is ideal for HVAC technicians, repair shops, and maintenance crews who service multiple machines and want a consistent replacement part that is ready to install. It is also a good choice for homeowners who are comfortable with motor repairs and need a matched set for laundry equipment, air compressors, or pumps.

Those who should look elsewhere include users needing a different capacitance range or a single replacement where buying five units is unnecessary. If a motor requires a non-oil dielectric type or has unusual terminal spacing, confirm fit before ordering.

Pros & Cons

Pros

• Works well as a direct replacement for many single phase motors and compressors, offering consistent performance.
• Good value for a five pack and praised by customers for quality and replacement fit.
• Rugged phenolic case, PCB-free construction, UL rated and backed by a 5 year warranty for peace of mind.
• Easy to install with 1/4' quick disconnect terminals, speeding service time.

Cons

• Size received mixed feedback from customers; confirm physical dimensions fit the equipment's mounting space.
• Sold in a pack of five, which may be more than needed for a single repair job.

Frequently Asked Questions

Can these capacitors replace OEM start capacitors?
Yes, they are designed specifically for replacement of OEM single phase motor start capacitors and match common capacitance and voltage needs.

Are these safe for residential HVAC and compressor use?
They are PCB-free, UL rated E492933 and suitable for typical residential and light commercial motors, but always disconnect power before servicing.

What if the capacitor does not fit my unit?
Check the 1.44 in diameter and 3.37 in height before ordering; if clearance is tight you may need a different form factor or a single replacement unit.
