The RV AC capacitor is a crucial component in your recreational vehicle’s air conditioning system. It stores and releases electrical energy to start and run the compressor and fan motors efficiently. Without a functioning capacitor, your AC unit may struggle to start, run inefficiently, or not operate at all.
Types of RV AC Capacitors
There are primarily two types of capacitors used in RV air conditioners:
- Start Capacitors: Provide the necessary torque to start the compressor.
- Run Capacitors: Maintain a consistent voltage supply to keep the compressor and fan motors running smoothly.
Some units use a dual-run capacitor, combining both functions in a single component.
Signs of a Faulty RV AC Capacitor
Identifying a failing capacitor early can prevent further damage to your AC unit. Look out for the following signs:
- AC unit struggles to start or doesn’t start at all.
- Unusual humming or buzzing noises.
- AC turns off unexpectedly.
- Visible bulging or leaking from the capacitor.
Testing and Replacing an RV AC Capacitor
Testing:
Before testing, ensure the power is disconnected. Discharge the capacitor by placing a screwdriver between the terminals. Use a multimeter set to the capacitance setting to measure the microfarads (µF). Compare the reading to the capacitor’s rated value.
Replacement:
- Disconnect power and discharge the capacitor.
- Note the wiring configuration or take a photo.
- Remove the faulty capacitor and replace it with one of identical specifications.
- Reconnect the wires and secure the capacitor.
- Restore power and test the AC unit.

FAQs
Q1: How often should I replace my RV AC capacitor?
Capacitors typically last 5-10 years, but it’s advisable to inspect them annually for signs of wear or damage.
Q2: Can I replace the capacitor myself?
Yes, if you’re comfortable with basic electrical tasks. Always ensure the power is off and the capacitor is discharged before attempting replacement.
Q3: What happens if I use a capacitor with incorrect specifications?
Using a capacitor with incorrect µF or voltage ratings can lead to inefficient operation or damage to the AC unit. Always match the specifications exactly.
Q4: Are dual-run capacitors better than separate start and run capacitors?
Dual-run capacitors save space and simplify wiring, but performance depends on the specific AC unit’s design and requirements.
Q5: Where can I purchase a replacement capacitor?
Replacement capacitors are available at hardware stores, RV supply shops, or online retailers. Ensure you select one that matches your AC unit’s specifications.
Maintaining your RV’s air conditioning system is essential for comfort during your travels. Understanding the role of the RV AC capacitor and ensuring it’s in good working condition will help keep your AC running efficiently.
