Rv Plugged In But No Power : Reasons & Solutions

If you own any recreational vehicle, you must have sometimes gone through this situation and must have felt bewildered about the same. Am I right? If yes, today’s article will help you a lot in this regard.

Well, your RV is just a giant smartphone that runs on a battery, just like you need to charge your phone’s battery after using it through a charger.

For an RV, it’s the same too. You will need to charge it after using or keep it plugged in, while using.

In the case of an RV, you need to charge it through a shoreline power outlet, which is the primary power source to an RV.

However, at times, you may notice that even if your RV is plugged in, there is no power yet. The lights are off, AC isn’t working, etc.

In short, your RV isn’t getting any power. Don’t worry! Below I have listed the possible reasons behind this and some ways to fix it all alone. So, let’s first understand the reasons behind this.

Rv Plugged In, But No Power: Here Are The Possible Reasons:

Below are the possible reasons why your RV isn’t getting any power even though being plugged into the campsite’s shoreline power outlet.

1. Electrical management system

Owing to some discrepancy with your RV’s electrical management system, the situation may arise.

These are not that much compatible with the 50-amp receptacles as they are with the lower ones like the 30-amp.

As a result, the RV may heave power at the split 50-amp hotline. There’s very little power to take up and keep your RV and its electronic components up and running in this case. 

2. An issue in the surge protector

As the name suggests, a surge protector is a component fitted in an RV whose main job is to prevent any type of surge in the input power to minimize the risks of blowing away the electrical components.

Now, if your RV is too old or has an old surge protector fitted you haven’t thought of replacing, there’s an issue with that surge protector for sure. So, it’s better to get it replaced from time-to-time.

3. Other issues with circuits, wiring, etc.

Sometimes, there is an issue with the RV’s circuit board or its wiring. You’ll have to access these either on your own or through an RV expert in both cases.

RV plugged in but no power: How to fix it?

Now, since you have confirmed that there is an issue and your RV isn’t pulling power to start up, here are some ways to fix it and some quick troubleshooting tips at the end.

Here’s how you can fix your RV’s power issue.

1. Check and reset the GFCI

GFCI stands for ground fault condition interrupt. It’s the main component of your RV’s electrical system that prevents your RV and you in case of any electric shock (if water gets onto it) or power up and down.

You can find it either in the bathroom, kitchen, outdoors, or wherever there’s water. So, checking and resetting it is your first task. It’s the best thing you can at first.

2. Reset the main circuit breakers

If you have any electrical knowledge, the next thing you can do is reset the main circuit breakers. If not, you can take help from the help manual to do so.

3. Check the batteries

As said in the beginning, working batteries are crucial to your RV. So, if there is no power, check the state of its batteries.

Are they damaged? Are the batteries leaking? The batteries are at higher risk of getting damaged in the winters due to freezing.

So, if that’s the case, you’d have to replace them with the new ones. As they contain toxic fluid, remember to take precautions.

4. Check the power shore

If the batteries are fine and not damaged externally, try disconnecting them from the current shoreline power source and connect to another source.

If it works, the problem is with your initial power source and not the batteries. So, change your shoreline power source. 

5. Check the fuse

Check the fuse, and if it’s blown out, you will have to replace it with a new one carrying similar electrical ratings.

Don’t forget to notice that the fuse you’ll use must have the required ratings because if it’s below that, the fuse won’t work correctly.

If the fuse is of higher ratings, it’ll allow more current to pass to the electrical components, causing damage. 

6. Check the battery charge

Pick up a multimeter and check the DC voltage of the battery. Ideally, it should lie between 13.4 to 14.5.

If the voltage is lower than this range, the possible reasons include a worn-out battery, insufficient water, or a bad converter throwing no power.

So, if your RV’s plugged in but no power is there inside or outside, check the battery’s charge.

7. Issue(s) in the park’s power grid

At times, after a complete inspection from inside, you may notice that there’s something bad outside with the park’s power grid.

If there is any issue with the park’s power grid, like it isn’t supplying the required power, improperly grounded, fluctuates, or a corroded connector, contact your campground’s management.

Additionally, you can have a word with the other campers and know if they’re experiencing the same due to the faulty power grid.

If that’s so, you can’t do anything, and only the park’s administration could resolve the issue with their power grid.

Quick troubleshooting tips:

  • If the GFCI outlet has tripped, reset it.
  • At the power pedestal, reset the main 110-volt circuit breaker.
  • Check whether the battery is damaged or incapacitated.
  • Disconnect the batteries from the shore power and check how the RV inverter responds.
  • Check the power to the surge protector and if diagnostic lights are ON/OFF.
  • If you have a generator, examine the power at the power transfer switch.
  • Check the wirings to the breakers and between them and the outlets.

These are some quick troubleshooting tips to keep going. While dealing with any of the above tips, make sure to practice caution at every stage.

If you’re a novice, follow the instructions manual as much as you can, and if you’re experienced in the same, know what you are doing.

Any mistake while examining the RV’s electrical components can lead to shocks and damage to the RV.

Conclusion

RV and its power problems go hand in hand with each other.

Whether your RV is new or old, if not an internal issue, any external issue will leave your RV without power. No matter what the reason is, the above ones should help you in the best possible way.
