MC 3314471.017MC RV Air Conditioner Motor Run Capacitor 55/15 MFD

The MC 3314471.017MC is an aftermarket replacement motor run capacitor designed for Dometic and Duo-Therm RV air conditioning systems. This dual-run capacitor provides the electrical energy needed to keep both the compressor and fan motors operating smoothly and efficiently.

Key Specifications:

• Capacitance Rating: 55/15 MFD (microfarad)
• Voltage: 370/440 VAC
• Operating Temperature Range: -40°F to +185°F (-40°C to +85°C)
• Safety Rating: 10,000 AFC
• Dimensions: 2-1/8" diameter x 4-5/8" overall height
• Three clearly labeled terminals: HERM (H) for compressor, FAN (F) for fan motor, C for common line

Function and Benefits:

• Stores and delivers electrical energy to maintain consistent motor speed
• Helps compressor start faster and reduces energy consumption
• Stabilizes voltage and current flow to reduce motor wear
• Extends the lifespan of air conditioning components
• Direct replacement for OEM Dometic part 3314471.017

Capacitors can sustain damage from power surges and will gradually wear down over time until they can no longer hold a charge. Common signs of failure include the AC struggling to start, unusual humming noises, frequent breaker trips, or the unit running only at low speed. This replacement capacitor restores normal operation and is compatible with Dometic Penguin II models including 640315, 640316, 641815, 641816, 641915, 650015, 651815, 651816, and 651916.
