Many RVers encounter a tripped switch or have blown a fuse at some point in time during their travels.
Unfortunately, if you don’t know where to look for the breaker or fuse box, you will encounter other problems down the line, like being stranded without power. That’s why it’s often incredibly important for you to know where to find your motorhome’s fuse box.
Since there are so many different locations it can be located, we thought it best to help you by telling you where you should look first.
What Are the Six Places You Can Find an RV Fuse Box?
Since every RV manufacturer has multiple floorplans, many models have fuse boxes in different locations. Additionally, certain brands will favor some areas over others.
After scouring the internet and RV forums, we created the list below that details six places you should look to find your motorhome’s fuse box.
Knowing the location of your fuses can help you eliminate specific troubleshooting problems:
1. Low to the Floor
The most common location for a motorhome’s fuse box is close to the ground inside an RV. Unfortunately, it can be anywhere inside a motorhome, but there are some places you are likely to find one.
For example, many Keystone models have fuse boxes between the stove and refrigerator on the ground level under the cupboard.
If you see a box with a black cover over it in this location, it’s likely, that you’ve found the fuse panel. Other keystone models, like the Passport 229RK, have fuse boxes on the floor to the left of the kitchen sink.
In various Jayco models like the FR Cherokee, the fuse box is near the floor but the TT. Cherokee has its fuse box below the fridge door, which is the perfect example of different models by the same brand having different fuse box locations.
Additionally, some motorhomes have fuse boxes near the floor but below the television hookups.
2. Inside an Electrical Storage Compartment
If you guessed that your fuse box was located inside an electrical storage compartment inside your motorhome, you could be right if you have an older Fleetwood model.
According to some Fleetwood motorhome owners, their fuse box is found with their 110-volt circuit breakers in the electrical compartment in a motorhome’s exterior storage compartments.
The exterior storage compartment where you could locate yours will depend on your motorhome’s manufacturer.
3. Inside a Dash or Black Box in the Engine Compartment
Some motorhomes will have the fuse box under the hood in front of the motor but situated closer to the driver’s side. Usually, the fuse box here will house the engine control fuses like the air conditioner system and fuel pump.
In addition, usually further to the right of this box, still under the hood, will be another fuse control panel that will have the fuses which control your RVs’ coach functions like the electric step.
Interestingly, in some motorhomes, a fuse panel or box is found inside a motorhome to the left of the steering column. This fuse panel is responsible for the lighting of an RV, like the brake lights and taillights.
When looking to see if your fuse box is under or inside the dash, you need to look for a removable panel, as some models will have the primary fuse box in this area.
According to a few Fleetwood motorhome owners, the location of a fuse box will depend on whether your fuse box was installed by the chassis manufacturer (usually Chevy or Ford) or the motorhome manufacturer Fleetwood.
For example, for Fleetwood Pace Arrow owners, if Chevy or Ford supplied your fuse box, you will likely find the fuse box situated to the left-hand side of a steering column either inside or under the dash.
In contrast, if Fleetwood installed your RVs fuse box, it is likely situated under the hood or above or behind your refrigerator near the 110-volt breakers.
4. At the End Of a Bed
One of the more interesting locations you can look for your fuse box is at the end of the bed in the primary bedroom of your motorhome.
Many RVers who own a Forest River Sunseeker model have reported that they have found their fuse box just above the floor at the end of their beds.
Although the location might be odd, many have found it easy to access since all that’s needed to open the panel the fuse box is behind is to push on the cover and let go.
Yet, you should note that this is not the same with all Sunseeker models by Forest River, especially newer models.
5. Under the Bathroom Sink
Did you know you can find your motorhome’s water pump or converter under the bathroom sink?
This is relevant because some RV manufacturers install an RV fuse box beneath the bathroom sink.
For example, the popular motorhome brand Jayco is well known for situating its 12-volt fuse box in this location.
6. Inside a Bedside Cabinet
Since you now know that you can find a fuse box at the end of a bed, it shouldn’t be surprising to learn that it could also be located inside a bedside cabinet.
Some Coachmen motorhomes have a fuse box inside a bedside table alongside 120-volt breakers. In addition, other models have a fuse box inside a kitchen cabinet.
What Is An Easy Way To Locate Your RV Fuse Box?
Often many RVers find it incredibly difficult to locate their RV fuse box.
Unfortunately, most of the process is trial and error, as you will have to try and search the locations we spoke of above. Alternatively, you can try to acquire your motorhome’s floor plan and detailed guide to determine if it reveals where your RV fuse box has been installed.
Additionally, you can also try a method that many RVers use. This method follows the shore power cord wiring to find your fuse box.
This can be tiring, so it’s often best to dedicate time to finding it before something goes wrong with the electrics in your motorhome.
You can also try listening to the ‘hum’ of the 120-volt circuit breakers grouped with your fuses and 12-volt power converter. Yet, to hear it, you will need to have your furnace switched off and your televisions.
When Your Fuses Aren’t Blown, It Could Be Problems With Your RV Circuit Breaker:
If you have electrical problems and your motorhome’s fuses aren’t blown, you could be experiencing various issues with your circuit breaker.
Firstly, what exactly is a circuit breaker?
In essence, an RV circuit breaker is a device that is installed to interrupt your RVs’ power supply should there be a sudden electrical surge (much like a residential home circuit breaker).
When a circuit breaker and fuse box work together, they protect your family from fire and damage to your motorhome’s electrical system.
So if you’re RV circuit breaker keeps tripping, and your fuses aren’t blown, there are a few things that could be causing a problem that you need to address.
There is an Appliance Short-Circuiting:
If one of your appliances is faulty or is drawing too much power, it could be short-circuiting your breaker and potentially causing your fuses to blow.
To fix this problem, you will need to switch off all your appliances and turn them on individually to find the one causing the issue.
The Circuit is Overloaded:
Your circuit breaker could constantly be tripping because you have too many appliances and lights running simultaneously.
That’s why it’s often best to have fewer lights on while running television and consider not having the air conditioner and microwave on simultaneously.
You have a Bad Breaker:
Unfortunately, if you have a bad breaker, it will trip continuously for almost no reason.
This means that you’ll need to replace your circuit breaker, but you need to be disconnected from shore power when doing so and not have a generator running.
Usually, it’s best to consider hiring a professional to replace your circuit breaker to avoid mishaps and accidents.
