Top Franklin Control Box Capacitors for 2026

The KuangBBBTools 105-126 MFD motor start capacitor is a direct replacement for Franklin well pump control boxes rated at 1.0, 1.5, and 2.0 horsepower. It is designed for homeowners, well service technicians, and pump repair professionals who need dependable starting torque to get a stalled motor running again.

This capacitor covers the 105 to 126 microfarad range and works with 220 to 250 volt AC systems at 50/60 Hz. It matches the electrical requirements of common Franklin control boxes, and the non-polarized terminals make wiring simple and reduce the chance of connection errors.

The round aluminum body measures roughly 2.05 inches wide and 3.39 inches high, fitting easily in the original control box space. It replaces Franklin part 275464118 and is compatible with multiple control box models, including 2823018110, 2801084915, 2823018310, and 2823508110. Most installations use nylon ties or a bent steel pin to hold the capacitor in place.

Before ordering, confirm that your control box matches the listed models and that the capacitance range suits your motor's start winding. This is a start capacitor, not a run capacitor, so it is not meant for continuous duty. Some users may need to supply their own mounting hardware if the original clips are missing.

Overall, the KuangBBBTools motor start capacitor offers a strong combination of fit, durability, and easy installation for Franklin pump systems. The aluminum case and larger housing promote better heat dissipation, making it a smart replacement for restoring reliable well pump operation.

Before buying a replacement start capacitor, check the capacitance rating printed on the original part. The replacement should match both the microfarad range and the AC voltage rating of the control box.

This KuangBBBTools capacitor is designed for Franklin 1.0, 1.5, and 2.0 HP control box models such as 2823018110, 2801084915, 2823018310, and 2823508110. If your control box is not listed, verify that the physical dimensions and electrical specs are compatible.

Keep in mind that a well pump control box normally contains one start capacitor and one run capacitor. The run capacitor is usually a CBB60 or CBB65 type, while the start capacitor provides extra torque only during motor startup. Replacing the right component is essential for reliable pump operation.

This start capacitor is a consumable component engineered for Franklin 1HP, 1.5HP, and 2HP well pump control boxes. It is a direct replacement for Franklin part number 275464113 and also fits control box models 2823008110, 2823018110, 2801084915, 2823018310, and 2823508110. If your pump is slow to start, hums, or trips the breaker, a weak capacitor may be the culprit.

Made in the USA by Barker Microfarads (BMI), this capacitor offers a 105-126 MFD range at 220VAC and works on 50/60Hz systems. The capacitance range matches the original Franklin spec, ensuring proper starting torque and smooth motor operation. Built with a plastic case and an 85°C temperature rating, it handles typical well pump duty cycles effectively.

The capacitor measures 3.35 inches high by 2.15 inches in diameter with a snap-in mount that fits the same mounting clips as the factory original. The cylindrical design is compact and durable, and the markings clearly show MFD and voltage ratings. Replacing a weak start capacitor with this unit restores full performance without replacing the entire control box.

The main drawback is the no-return policy for electronic components, so double-check your control box model before ordering. Also, this is only the start capacitor, not a complete control box or run capacitor. For most Franklin-compatible systems, it is an exact fit, but if you have a non-listed brand, verify compatibility via your existing capacitor spec.

For owners of Franklin 1HP to 2HP well pump systems, this TuhorsePumps start capacitor is a reliable and cost-effective replacement. It delivers OEM-grade specs in a USA-made package, and the high user rating confirms its performance. Skip the service call and keep your water flowing by swapping in this capacitor at the first sign of starting trouble.

The KuangBBBTools 86-103 MFD Motor Start Capacitor is a direct replacement part designed for Franklin and CRC well pump control boxes, specifically for 3/4 and 1 HP pumps. This capacitor is ideal for homeowners or technicians looking to restore a non-starting well pump without replacing the entire control box.

Its standout feature is compatibility: it fits Franklin Control Box 2801074915, CRC 2824085015, and similar models, directly replacing Franklin part #275464118. The larger body housing improves heat dissipation, which is critical for capacitor longevity in enclosed control boxes. Customers report easy installation using nylon ties or a steel pin, and many confirm it works immediately.

Build quality is typical for a plastic start capacitor: round shape, snap-in mount, and rated for 250V AC. The manufacturer emphasizes a more durable design with better heat management. However, the plastic shell is not as thermally conductive as aluminum, though users note the larger size helps.

Potential drawbacks include a small risk of early failure, as one review noted the capacitor smoked and failed within 24 hours. Additionally, the capacitor lacks the depletion resistor sometimes found on original parts, which could affect compatibility with certain control circuits. Most users found it a perfect fit, but those with older systems should verify requirements.

Overall, this capacitor offers excellent value for a targeted fix. It is a reliable choice for common well pump applications, provided you purchase from a trusted seller and monitor for any initial issues. For the price, it is a smart spare to keep on hand.

This BlueNatHxRPR start capacitor is designed as a drop-in replacement for well pump control boxes, particularly Franklin Electric 3/4 HP and 1 HP models. It is ideal for homeowners or technicians looking to fix a failed pump without replacing the entire control unit.

With a capacitance rating of 86-103 MFD and a maximum voltage of 250V AC, it delivers the precise surge needed to start single-phase well pump motors. The aluminum CBB65 housing provides excellent heat dissipation, ensuring reliable operation even in demanding conditions.

The capacitor measures approximately 2 inches in diameter and 3.3 inches tall, fitting easily into standard control boxes. Its round shape and press-fit mounting simplify installation using nylon ties or bent steel pins, as noted in the product description.

A minor drawback is that delivery may not offer next-day options, which could be inconvenient during an emergency.
