The Dometic Brisk Air Capacitor Kit (Part# 3100248.602) is a genuine OEM dual run capacitor designed specifically for Dometic Brisk Air rooftop air conditioners. This 50/15 MFD capacitor provides the electrical start and run support for both the compressor and fan motor in your RV's AC unit. If your air conditioner won't start, runs intermittently, or the fan operates but cooling is weak, a failed capacitor is often the culprit. This direct replacement part restores proper operation and is essential for maintaining your RV's climate control system.

Frequently Asked Questions
How do I know if my AC capacitor has failed?
Common signs include: AC won't start at all, compressor hums but doesn't run, fan runs but no cooling occurs, or intermittent operation. A bulging or leaking capacitor is a visual indicator of failure. Always discharge capacitors safely before testing or replacing.
What does 50/15 MFD mean on a dual run capacitor?
The 50 MFD (microfarad) rating provides start and run power for the compressor, while the 15 MFD rating powers the fan motor. Both functions are housed in a single capacitor unit with separate terminals. Using the correct capacitance ratings is critical for proper AC operation.
Can I replace this capacitor myself?
If you're comfortable working with electrical components and follow proper safety procedures, yes. Always disconnect shore power and turn off the breaker before starting. Discharge the old capacitor before removal. Take a photo of wire connections before disconnecting to ensure correct reinstallation. If unsure, consult a qualified RV technician.
How long do AC capacitors typically last?
RV air conditioner capacitors typically last 5-10 years depending on usage and operating conditions. Extreme heat, frequent cycling, and voltage fluctuations can shorten lifespan. It's a good practice to inspect capacitors annually and replace them at the first sign of bulging, leaking, or performance issues.
