5 Pack TEMCo 189-227 uF 110-125V AC Start Capacitor - Reliable Motor

In this review the 5 Pack TEMCo 189-227 uF motor start capacitors are evaluated for service technicians and DIYers who need dependable replacements for single phase motors. The bottom line: these capacitors deliver solid starting torque and long-term reliability for HVAC units, compressors, pumps and washing machines because they are PCB-free, UL rated and oil filled, making them a straightforward, rugged swap for worn OEM parts. They are best chosen when matching capacitance and voltage to the original specification is the priority.

Key Features

• Capacitance Range: The 189-227 uF rating covers common OEM start needs so replacements reliably restore starting performance.
• Voltage Compatibility: Rated 110-125 VAC and suitable for 50/60 Hz, it works across typical residential and light commercial single phase supplies.
• Durable Construction: The electrolytic oil filled design in a rugged phenolic resin case provides mechanical protection and stable operation in motor enclosures.
• Temperature Range: Operates from -40 C to +65 C so it tolerates a wide range of ambient conditions found in basements, garages and HVAC closets.
• Standard Terminals: 1/4 in quick disconnect terminals make installation fast and compatible with common wiring connectors.
• UL Rated and PCB-Free: UL rating E492933 and PCB-free construction reduce environmental concerns and simplify safety consideration for replacements.

Who It's For

This 5 pack is aimed at maintenance technicians, small shop owners and homeowners who service multiple machines or want spare parts on hand. It is particularly useful for replacing start capacitors in compressors, pumps, single phase motors and household appliances where the original spec falls within 189-227 uF and 110-125 VAC.

Those who should look elsewhere include users needing run capacitors, very low-profile parts for tight spaces smaller than the stated 1.44 in diameter, or replacements for three phase motors. Match the capacitance and physical size before purchasing to ensure fit and function.

Pros & Cons

Pros

• Works well to restore starting power in single phase motors and compressors according to customer reports.
• Good value and quality for a multi-pack, giving spare parts without high per-unit cost.
• Easy to install with standard 1/4 in quick disconnect terminals and a common footprint for many OEM swaps.
• Rugged, oil filled design with UL rating offers durable performance across a wide temperature range.

Cons

• Size receives mixed feedback; the 1.44 in diameter and 2.75 in height may be smaller or larger than some OEM housings, so physical fit should be checked.
• Designed for start duty only; it is not a direct substitute for run capacitors or non-electrolytic types.

Our Verdict

The 5 Pack TEMCo 189-227 uF start capacitors are a practical, cost-effective option for technicians and DIYers who need reliable OEM-style replacements for single phase motors. Their UL rating, oil-filled construction and broad temperature tolerance make them a trustworthy choice for HVAC, compressor and pump start duties, provided the physical dimensions and start-only duty are appropriate for the application.

Frequently Asked Questions

Can these replace a failed OEM start capacitor?
Yes, if the OEM spec falls within 189-227 uF and 110-125 VAC and the physical size and terminal style match, they make a suitable replacement.

Are these safe for HVAC and compressor use?
They are UL rated and PCB-free with a rugged case and oil filling, which makes them appropriate for HVAC and compressor start circuits when the ratings match.

Do these work as run capacitors?
No, these are designed specifically as start capacitors; they should not be substituted for run capacitors which have different construction and duty ratings.
