Frequently Asked Questions About Coleman RV Air Conditioner Capacitors

Getting to know your RV’s AC components can save you a lot of hassle. Here are some common questions about capacitors:

Q1: What exactly does a capacitor do in a Coleman RV AC unit?
A: Think of a capacitor as a temporary battery that gives your AC’s motors (both the compressor and the fan motor) a powerful jolt of electricity to start up. Once they’re running, a “run capacitor” helps maintain a consistent electrical flow, ensuring smooth and efficient operation.

Q2: How do I know if my Coleman RV AC capacitor is bad?
A: Common symptoms of a failing capacitor include:
– The AC unit hums but doesn’t start.
– The fan or compressor starts slowly or sporadically.
– The unit blows warm air (if the compressor capacitor is bad).
– The circuit breaker trips frequently when the AC tries to start.
– You might even notice a bulging or leaking capacitor if you visually inspect it (always disconnect power first!).

Q3: Can I replace a Coleman RV AC capacitor myself?
A: Yes, many RVers with basic electrical knowledge and proper safety precautions can replace a capacitor. However, capacitors can store a dangerous electrical charge even after power is disconnected, so it’s crucial to discharge them safely before handling. If you’re uncomfortable, it’s always best to call a professional.

Q4: What’s the difference between a start capacitor and a run capacitor?
A: A start capacitor provides a powerful surge of electricity to help the motor overcome initial inertia, then disconnects once the motor is running. A run capacitor, on the other hand, stays in the circuit throughout the entire operation, continuously regulating the current to keep the motor running efficiently and smoothly. Some AC units use a “dual run capacitor” for both the compressor and the fan motor.

Q5: What are hard start kits, and when do I need one?
A: A hard start kit combines a powerful start capacitor with a relay (often a PTCR device) to provide an extra boost for the compressor motor. You might need one if your RV AC struggles to start due to low voltage (common in older RV parks or when running on a generator), causes lights to dim, or trips breakers during startup. They significantly improve starting performance and extend compressor life.

Q6: What microfarad (µF) and voltage (VAC) rating should I look for?
A: Always match the µF (microfarad) rating exactly to your original capacitor. This indicates its capacitance. The VAC (voltage) rating should be equal to or higher than your original to ensure it can handle the electrical load. Never use a capacitor with a lower VAC rating.

Q7: How long do RV AC capacitors typically last?
A: The lifespan of an RV AC capacitor can vary, but they generally last between 5 to 10 years. Factors like extreme heat, frequent starts, voltage fluctuations, and overall usage can shorten their lifespan. Regular inspection during preventative maintenance can help catch issues early.

Q8: Are Coleman Mach series capacitors specific to those models?
A: Many capacitors are designed to be OEM-compatible with specific Coleman Mach series models. While some are more universal (matching µF/VAC ratings), it’s always best to check the product’s compatibility list against your exact Coleman Mach model number to ensure a perfect fit and optimal performance.
