Screw Man RV Air Conditioner Motor Capacitor 55/15 MFD 3314471.017 Dual Start/Run, Improved Motor Starts

Screw Man's 55/15 MFD motor capacitor (model 3314471.017) is a direct-fit replacement designed to help RV air conditioner motors start smoothly, stabilize running current, and improve energy use.

This compact capacitor is built for rooftop RV air conditioning compressors and blower motors that require a dual-value start/run component (55/15 microfarads). It supplies the extra current needed at motor startup, stores and releases electrical energy to improve power factor, and helps maintain steady voltage while the unit runs. The part is offered as a compatible replacement for many Dometic systems that list the 3314471.017 specification.

How does this capacitor help my RV air conditioner start reliably?

At motor startup, the capacitor provides a burst of phase-shifted current that improves torque and helps the compressor or fan overcome initial inertia. That reduces the number of failed starts and minimizes stress on the motor windings and starter components.

• Dual capacitance: 55 µF start and 15 µF run support
• Delivers extra current for initial motor torque
• Reduces mechanical and electrical stress during startup

Will replacing the capacitor make my AC more energy efficient?

The capacitor can't change the AC's cooling capacity, but by improving the motor's power factor and smoothing current draw it can help the system run more efficiently. A correct-value capacitor ensures the motor operates nearer to its design performance, which can lower wasted energy and reduce cycling issues caused by poor electrical balance.

• Improves power factor through stored/released energy
• Helps maintain steady motor speed and reduced current spikes
• Can reduce wasted electricity from inefficient starts and operation

Is this a direct replacement for Dometic RV AC models?

This Screw Man part is manufactured to match the 3314471.017 specification and 55/15 MFD ratings, making it compatible with Dometic units that list that part number or require those capacitance values. Always cross-check your appliance's specification plate and wiring before installing to confirm fit and electrical compatibility.

• Matches model number 3314471.017 and 55/15 µF values
• Designed for rooftop RV air conditioner motors and blowers
• Verify voltage and terminal layout before replacement

What practical benefits will I notice after I install this capacitor?

After installation you may observe smoother motor starts, less clicking from attempts to restart, and quieter operation due to stabilized voltage and current. Over time these improvements can reduce wear on motor bearings and starters, potentially extending component life and lowering maintenance calls.

• Smoother, quieter motor engagement at startup
• Reduced electrical surges and motor vibration
• Potentially fewer premature motor or starter failures

Who is this for: RV owners and mobile-home technicians who maintain rooftop air conditioners and need a reliable, specification-matched replacement for Dometic-compatible motors. It's suited to DIYers comfortable with electrical parts replacement and professional installers seeking a direct-fit 55/15 µF capacitor to restore proper motor starting and running behavior. Always power down and follow safety procedures or consult a qualified technician for installation.
