Dometic AC Dual Run Capacitor 35/5 MFD - Fits B59516.XX Series - Part# 3100248.362

The Dometic 3100248.362 is a genuine OEM dual run capacitor designed specifically for Dometic RV air conditioners in the B59516.XX series. This 35/5 MFD capacitor provides the electrical boost needed to start and run both the compressor and fan motor in your rooftop AC unit. If your air conditioner won't start, runs intermittently, or the compressor hums without starting, a failed capacitor is often the culprit—and this is the exact replacement part you need.

Frequently Asked Questions

How do I know if my capacitor has failed?

Common signs include: AC won't start at all, compressor hums but doesn't run, fan runs but compressor doesn't engage, or intermittent cooling. A bulging or leaking capacitor is a visual confirmation of failure. Always discharge capacitors safely before testing or replacing.

Can I use a universal capacitor instead of this OEM part?

While universal capacitors exist, using the genuine Dometic OEM capacitor ensures exact specifications, proper mounting configuration, and reliable performance. The 35/5 MFD rating must match exactly—using incorrect capacitance can damage your compressor or fan motor.

What tools do I need to replace this capacitor?

You'll need a screwdriver to access the AC unit's electrical compartment, needle-nose pliers for wire terminals, and an insulated screwdriver to safely discharge the old capacitor. Always turn off power at the breaker before working on your AC unit, and if you're not comfortable with electrical work, consult a qualified RV technician.

Will this capacitor fit other Dometic AC models?

This capacitor is specifically designed for B59516.XX series air conditioners. While the electrical ratings might match other models, mounting configurations and terminal arrangements can vary. Always verify your model number and existing part number before ordering to ensure proper fit.
