RV Not Getting Power When Plugged In At The Campsite
It’s an RV enthusiast’s worst nightmare: you’ve spent hours on the road in your vehicle, fighting traffic, crawling your way across lanes for endless miles, and now.
Finally, you’ve reached your destination, parked your vehicle, and are ready to unwind in your state-of-the-art home away from home.
So you plug in your RV, but you’re not getting any power! What on earth is going on?
1. Check And Reset The GFCI.
The first thing you should do when troubleshooting your lack of power is to check your RV’s main GFCI, the Ground Fault Circuit Interrupter.
This is often located in your vehicle’s bathroom, but not always.
Check your RV’s manual if you’re unsure of its location or how to reset it.
Do that before you hit the road, so you won't have to waste time looking for that manual when in the campground (or worse, find that you don't have it with you).
This is the easiest way to solve power problems in your RV and should absolutely be the first step you take when troubleshooting this issue.
2. Reset Main Circuit Breakers.
Try resetting the main circuit breakers at the power pedestal and the main 110-volt circuit breaker.
This should be a pretty straightforward process. But as always, check your RV's manual if you're not sure what to do.
And don't proceed if you feel unsafe or unsure.
When in doubt, consult a licensed RV professional!
3. Give The Main 110-volt Circuit Breaker A Reset.
The main 110-volt circuit breaker in your RV is like the master switch for your power.
If there's an issue, resetting this breaker can sometimes fix it, just like how turning a gadget off and on again can make it work.
Here's a simple breakdown of what to do:
Locate the Breaker: First, you need to find where this 110-volt circuit breaker is in your RV. Typically, it's in a box with other switches, often labeled.
Safety First: Before touching anything, ensure your hands are dry and standing on a dry surface. This will keep you safe from any electrical issues.
Turn Off, Then On: Once you locate the breaker, flip it to the "off" position. Wait for a moment. Then, flip it back to the "on" position.
Listen and Look: When you flip the breaker back on, listen for any sounds or look for any lights that might indicate the power is back. If things are still not working, there might be another issue.
Always remember, if you ever feel unsure or unsafe about handling electrical components, it's best to ask for help or call a professional.
4. Check Batteries.
Check your vehicle’s batteries.
How do they look? Are they leaking, or do they appear damaged in any way?
Vehicle batteries can take a beating, but they're not invincible, particularly in winter when they’re prone to freeze.
If they are damaged, be sure to wear protection before handling them.
Battery fluid is toxic and can lead to burns and other unpleasant side effects when in contact with human skin.
5. Check Inverter Response.
When the batteries look okay, disconnect them from the initial shore power and reconnect to an alternate source. If everything works, the issue is likely with the shore power, not your RV - hurray!
If it doesn’t work, disconnect the batteries and observe the inverter response. Do any lights come on? If so, your batteries may have damaged cells and need repair or replacement.
Focus on the inverter's indicator lights and error codes when disconnecting the batteries. Changes in the lights or displayed codes can signify issues. Refer to your manual to understand the codes.
If the inverter shows no life at all, it could be faulty or unable to get power. Try reconnecting the batteries and connecting the inverter to another power source to test its functionality.
Visually inspect the batteries, too. Check for damage, leakage or corrosion that could impact the inverter and cause power problems. Use a multimeter to check battery voltage - significantly low readings indicate faulty batteries.
Understanding the inverter's specific responses, testing its operation, and evaluating the batteries is key in diagnosing RV power issues. Refer to manuals, and don't hesitate to call a professional if needed.
6. Disconnect From Shore Power.
Here’s where things get more technical and require special tools to proceed.
Using a voltmeter or test light, disconnect your shore cord from the power pedestal, reset the breaker, and test for power at the outlet. (Note: The power pedestal is the external source of electrical power to which your RV is connected when parked.)
If power is there, turn off the breaker, reconnect the power cord, and then power the breaker on.
Then, move to where the shore cord connects to the RV and test for power.
7. Check The Surge Protector.
If your voltmeter finds power flowing, check to see if your RV has a surge protector.
If your surge protector has diagnostic lights, inspect them to ascertain if power is passing through. No lights could signify a defective surge protector contributing to your power issues.
For surge protectors without diagnostic lights, you can test their functionality by plugging in an appliance that’s in working condition into the RV while the RV is connected to shore power.
If the appliance does not work, this could also indicate that your surge protector may be malfunctioning, and could be the source of your power issues.
In both scenarios, consider consulting your surge protector's manual for troubleshooting steps or reaching out to the manufacturer's customer service for assistance.
8. Test The Inverter/Converter And The Power Transfer Switch.
If everything is still looking as it should, check your charger/inverter or converter for power, and if you have a generator, test its power transfer switch.
Note: The transfer switch is a device that switches electrical load from shore power to generator power or vice versa, ensuring that both sources do not connect to the electrical system simultaneously.
Checking the Inverter/Converter:
When examining the inverter or converter, ensure it is providing the correct output voltage by using a voltmeter. The exact output voltage should be listed in the appliance’s manual.
- Expected Outcome: The output voltage on the voltmeter should match the stated output voltage in the manual.
- Signs of an Issue: If the output voltage is zero or significantly less than the stated output, it is an indication of a problem with the inverter/converter.
Ways of checking these devices can vary by model, so refer to your RV’s operating manual for specific instructions.
Checking the Power Transfer Switch:
Also, ensure that power is seamlessly flowing between the power transfer switch/power cord and the inverter/converter. If the transfer switch is not properly transferring power from the source to the inverter/converter, it could be faulty.
- Expected Outcome: Power should be transferred without interruption.
- Signs of an Issue: If there is no power transfer, it could indicate a malfunctioning transfer switch.
Ensure to use all safety precautions and consider seeking professional assistance if unsure about the testing process.
9. Check The Breaker.
Time to check the main 110-volt circuit breaker. It’ll probably be housed under a panel, which you’ll have to remove to get to.
If the wires connecting to the breaker have power, your breaker may be faulty and have to be replaced.
Be sure that you’re checking the breaker’s power out rather than power in, as breakers sometimes tend to go bad or rust to the point of inoperability.
Finally, if there’s still no power, check the wiring between the breaker and the power outlets.
There might be a loose or broken connection somewhere that’s causing your vehicle’s inability to take in power.
It’s possible fixing this issue will require more professional expertise.
When all else fails...
If you have checked all the items on the list and still cannot find the problem, take your RV to the nearest repair facility.
They will be able to diagnose and fix the problem. Trust them; they’re experts!
Just In Case: 3 Extra Places to Check
1. Shore Power Cord Damage
When experiencing power issues with your RV, it's important to inspect your shore power cord for signs of wear and tear.
The shore power cord transfers electricity from the external power source to your RV's electrical system.
Over time, it may become frayed or damaged, leading to a loss of power or inconsistent power supply.
Ensure the cord is securely connected to the power pedestal and your RV's power inlet.
If you see any signs of damage or the connections are loose, your power issues likely stem from the cord.
In such cases, replacing the damaged cord or ensuring secure connections can help restore power to your RV.
2. Fuse Box
Just as you would check the circuit breakers, examining the fuse box in your RV when faced with power issues is essential.
The fuse box contains multiple fuses that protect your RV's electrical circuits by breaking the circuit when there's a current overload.
If a fuse is blown, it can't complete the circuit, leading to a loss of power in specific areas of your RV.
Open your RV's fuse box and visually inspect each fuse for signs of damage, such as a broken filament or a darkened glass tube.
If you find a blown fuse, replace it with one of the same rating.
Remember, using a fuse with a higher rating than recommended can further damage your RV's electrical system.
3. Voltage Issues
In some cases, power issues in your RV may arise from incorrect voltage at the power source.
When you plug your RV into a shore power outlet, it's crucial to ensure that the voltage matches your RV's requirements.
RV electrical systems typically operate on 30-amp or 50-amp service, and plugging into an incompatible power source can lead to voltage issues, potentially damaging your RV's electrical components.
Use a voltmeter to check the voltage at the power pedestal before plugging in your RV.
If the voltage doesn't match your RV's specifications, it may be necessary to use an adapter or find an alternative power source.
Properly matching the voltage ensures a safe and stable power supply for your RV.
3 Ways to Prevent RV Power Issues
Now, we'll discuss a few measures you can take to prevent RV power issues.
1. Charge your batteries
RV batteries aren’t able to recharge themselves in the same way automotive batteries do, making them more prone to unexpected discharges and failures.
They’re a lot more powerful and, as a result, require a lot more power and maintenance than your standard, run-of-the-mill car batteries.
Charging them is often a simple matter of plugging your RV into a compatible AC outlet and waiting until it’s full.
This can take anywhere from a few hours to an entire day.
2. Keeping an RV plugged in
Many RV owners habitually keep their batteries plugged in even when their vehicles are stationary to ensure their electronics remain operational.
However, it's crucial to note that continuously leaving your RV plugged in can potentially affect the battery's electrolyte levels, especially in certain types of batteries, such as lead-acid batteries.
This slow drain, even if the battery is not fully discharged, can lead to decreased battery life and efficiency.
- For lead-acid batteries, prolonged charging can lead to the evaporation of electrolyte levels, causing damage over time.
- For other types of batteries, the impact may vary. It’s essential to consult the specific battery manual for detailed information regarding prolonged charging and potential effects.
To avoid this, ensure to periodically unplug your RV and check the battery’s conditions, including the electrolyte levels (for batteries that allow for such checks), to ensure optimal functionality and longevity.
3. Good Housekeeping
RV owners who consistently keep their vehicles plugged in for extended periods should vigilantly monitor their battery electrolyte levels monthly to ensure they remain in optimal condition.
This advice predominantly applies to those using lead-acid batteries.
Important Reminder: Always switch off any 120-volt appliances before storing your RV to prevent unexpected power drains or hazards.
