Pros
- Exact OEM specification replacement
- Made in USA by Barker Microfarads
- Fits multiple Franklin models
- Compact design fits standard control box
- High customer satisfaction rating
Cons
- No returns on electronic components
- Not a universal fit, verify your control box model
- Only the capacitor, not a full control box
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.
Pros

Buying Guide
Compatibility with Your Pump’s Horsepower and Voltage
Every Franklin control box part must match your pump’s horsepower (HP) and voltage. A 1 HP pump requires a capacitor rated for its starting load, while a 2 HP system needs heavier components. For example, the 105-126 MFD (uF) 1.0 1.5 and 2 HP Well Pump capacitor fits multiple HP ranges, but always check the control box model number. If you’re upgrading or replacing a complete box, the Control Box, 1 1/2HP, 230V, 1Phase is a direct fit for submersible motors. For more on sizing, read our complete well pump kit guide for home systems.
Component Type: Capacitor, Relay, or Complete Box
Decide whether you need a single component or a full control box. Start capacitors like the 105-126 MFD (uF) Motor Start Capacitor Compatible are consumable parts that lose capacity over time. Relays, such as the rva2alkl Control Box Well Pump Relay, handle switching and often fail after years of use. If multiple parts are worn, a complete box like the Red Lion RLCB10-230 1-HP 230-Volt VMC Control Box simplifies replacement. For a broader overview, check our well pump kit buying guide.
Build Quality and Brand Reputation
Franklin Electric and Red Lion are trusted names in the industry. The FRANKLIN ELECTRIC 1 HP Submersible Water Pump control box is made in the USA and designed for 3-wire motors. For a larger system, the Franklin Electric 2 Hp Submersible Water Pump control box offers the same reliability. Third-party capacitors from TuhorsePumps and BlueNatHxRPR are also well-reviewed, but always verify they meet OEM specifications. A quiet pump setup often depends on quality control parts; see our top quiet well pump picks for noise-reducing options.
Ease of Installation
Most Franklin control box parts are designed for straightforward replacement. Capacitors and relays typically plug into terminals or mount with screws. Complete boxes require wiring the incoming power and motor leads. If you’re comfortable with basic electrical work, you can swap a capacitor in minutes. For more complex jobs, consider hiring a professional. A well pump that feeds a pressure tank needs a correctly installed control box; our guide to well pumps for pressure tanks covers integration tips.
Final Thoughts
When you need Franklin control box parts, focus on compatibility and quality. For a direct OEM replacement, the FRANKLIN ELECTRIC 1 HP Submersible Water Pump control box delivers reliable performance for 1 HP systems. If you only need a capacitor, the 105-126 MFD (uF) 1.0 1.5 and 2 HP Well Pump capacitor from TuhorsePumps is a cost-effective choice that matches Franklin specifications. Either way, you’ll keep your water flowing without unnecessary downtime.
Frequently Asked Questions
What are common Franklin control box parts that fail?
Start capacitors and potential relays are the most frequent failures in Franklin control boxes. Capacitors lose capacitance over time, while relays can stick or burn out. Complete control boxes may also fail due to overheating or moisture ingress. Regular inspection every few years can catch issues early.
How do I know which capacitor to replace in my Franklin control box?
Check the label on your current capacitor for the microfarad (MFD) rating and voltage. For Franklin 1 to 2 HP boxes, the common range is 105-126 MFD at 220-250V AC. Match the shape and terminal type as well. If the capacitor is swollen or leaking, replace it immediately.
Can I replace a Franklin control box relay myself?
Yes, if you have basic electrical knowledge and can safely disconnect power. The relay is usually mounted on a bracket and connects with push-on terminals. Ensure the replacement relay matches the voltage and current rating of your pump. For 5-15 HP pumps, the rva2alkl Control Box Well Pump Relay is a direct fit for many Franklin models.
What is the difference between a start capacitor and a run capacitor in a well pump control box?
A start capacitor provides a high torque boost to start the motor, then is switched out by the relay. A run capacitor stays in the circuit to improve efficiency and power factor during operation. Most Franklin control boxes use only a start capacitor; run capacitors are found in capacitor-start/capacitor-run (CSCR) designs. For more details, see our well pump for pressure tank.
