430-516 uF 220-250V Motor Start Capacitor - Reliable OEM Replacement

In this review of the 5 Pack TEMCo 430-516 uF motor start capacitor, the bottom line is simple: technicians and DIYers needing a direct, economical replacement for single phase HVAC compressors, pumps, and motors will appreciate the combination of correct electrical specs and straightforward installation. The reviewer found the capacitors to be a practical swap-in option when the original start capacitor fails, delivering expected starting torque and compatibility across common 220-250 VAC systems while offering a lower-cost alternative to OEM parts.

Key Features

• Capacitance range: 430-516 uF provides the start boost required by many single phase compressors and motors for reliable initial torque.
• Voltage rating: 220-250 VAC rating matches common HVAC and compressor circuits for safe operation when installed correctly.
• Temperature tolerance: -40 C to +65 C rating ensures the unit can operate across typical equipment ambient conditions.
• Construction: PCB-free, electrolytic oil filled design in a rugged phenolic resin case gives durable insulation and protection for the internal elements.
• Terminals and fit: 1/4 in quick disconnect terminals and a 1.77 in diameter make it easy to fit into many motor capacitor housings for fast replacement.
• Certification and warranty: UL rated E492933 and a 5 year warranty provide a level of quality assurance and post-purchase support.

Who It's For

This pack is aimed at technicians, maintenance teams, and informed DIYers who replace worn or failed single phase motor start capacitors in HVAC systems, compressors, pumps, and gear motors. It is particularly useful where the original part has similar electrical and physical specs and a quick swap is preferred to restore motor starting performance.

Those who need an exact physical match for oversized or nonstandard capacitor cans, or who require specialized longevity guarantees beyond typical use, should verify dimensions and consider OEM-specified replacements. Also, installation by someone comfortable with mains wiring and safety precautions is recommended.

Pros & Cons

Pros

• Good value: the pack price makes replacing multiple units economical compared with OEM parts.
• Functional fit: customers report easy installation and correct operation in HVAC and compressor systems.
• Durable construction: oil filled and PCB-free with a rugged phenolic case and UL rating for safety.

Cons

• Size difference: some users noted the capacitor is physically smaller than their original, so checking dimensions is important.
• Durability concerns: a few reports of premature failure or catastrophic failure mean users should follow installation best practices and test after install.

Frequently Asked Questions

Will this replace a 440 uF start capacitor?
Yes, the 430-516 uF range covers a 440 uF requirement, provided the voltage and physical dimensions also match the original unit.

Is this capacitor safe for outdoor compressor use?
The unit is rated -40 C to +65 C and is UL rated, but ensure the compressor housing provides proper protection and mount according to the equipment manufacturer.

Do I need special tools to install?
Standard hand tools and correct safety precautions for mains wiring are sufficient; the 1/4 in quick disconnect terminals allow simple connection to existing leads.
