How to Remove Firefly RV Control Panel: Complete DIY Guide (2024)

Quick Take

Firefly display panels use different mounting systems depending on the model - some use spring clips, others use screws, and some have twist-lock mechanisms. Before removal, check your specific Firefly model to determine the correct mounting system. For models with spring clips, the panel is secured by plastic clips that grip the mounting bracket from behind, and many people break things because they try to pry from the sides or look for screws that don't exist. With the right technique, you can safely remove it without damaging the wood paneling or screen.

Common Causes

The biggest reason people break their Firefly panels or surrounding woodwork is misunderstanding how these units are mounted. Unlike traditional wall switches with visible screws, Firefly displays use a spring-loaded mounting system with clips that engage from behind the bezel. People often damage their units by trying to pry around the edges with screwdrivers or knives, thinking there are hidden tabs to release.

Another common mistake is applying uneven pressure when pulling, which can crack the LCD screen or snap the plastic mounting tabs. The wood paneling gets damaged when people try to insert tools between the display and the wall, gouging or cracking the finish. Some owners also pull too hard on just one corner, which puts stress on the internal mounting points and can break the display housing.

Temperature also plays a role - if your RV has been in cold weather, the plastic clips can become brittle and more prone to breaking. The mounting system works best at room temperature when the plastic has some flexibility.

Preparation

WARNING: Disconnect power to the Firefly system by turning off the 12V DC disconnect switch or removing the fuse for the panel circuit to prevent any potential shorts or damage to the electronics. Take photos of how the display sits in the wall opening so you have a reference for reinstallation. Clear the area around the panel of any items that might get in your way or fall during the process.

First, locate and record your Firefly model number (usually on a label visible on the display or check your RV documentation) and consult manufacturer specifications for the correct removal procedure. Gather the appropriate tools based on your model: for spring-clip models, you'll need a small flashlight or headlamp and soft towel; for screw-mounted models, gather the appropriate screwdriver; for twist-lock models, see manufacturer specs for specific requirements.

If possible, warm up your RV interior to around 70°F before starting. This ensures the plastic mounting clips are at their most flexible and less likely to break. Also, make sure you have adequate lighting in the area - you'll need to see clearly to avoid applying pressure in the wrong spots.

Have your camera or phone ready to immediately photograph the back of the unit once it's removed, since Firefly support typically needs clear images of specific label information for their updates.

Repair Steps

Start by identifying your Firefly model number and checking the manufacturer specifications for the correct mounting system. For spring-clip models, you'll notice there's a slight gap all around the perimeter between the display bezel and the wall. For screw-mounted models, look for visible screws around the bezel. For twist-lock models, check for rotation indicators. Only proceed with the pull-out method if you've confirmed your model uses spring clips.

Apply steady, gentle pressure pulling straight out from the wall - not up, down, or to either side. You should feel the panel start to move with moderate force, though the exact amount needed can vary depending on your specific panel's mounting system. The spring clips are designed to release gradually, so don't expect it to pop out suddenly. If you encounter significant resistance, stop and reposition your grip to ensure you're pulling evenly.

As the panel starts to come out, you'll hear small clicking sounds as the clips release. Continue pulling straight out until the display is free from the wall opening. The unit will come out with several inches of wiring still connected, which is normal - don't disconnect anything unless Firefly support specifically requests it.

Once removed, carefully flip the display over to access the back panel where the identification stickers are located. Take clear, well-lit photos of all labels and stickers, making sure model numbers, serial numbers, and any other identifying information is clearly visible. Firefly support typically needs these details to provide the correct firmware updates for your specific unit.

To reinstall, simply align the display with the wall opening and push it straight back in until you hear the clips engage and the panel sits flush with the wall surface.

When to Get Help

If you encounter significant resistance when pulling and the panel doesn't start moving with moderate pressure, stop and contact a qualified RV technician. Forcing a stuck panel can result in expensive damage to both the display and your wall. Some units may have additional securing methods that aren't immediately obvious, especially if previous owners or technicians have modified the installation.

Call for professional help if you notice any cracks developing in the display screen or housing during your removal attempt. LCD screens are particularly fragile and expensive to replace - costs vary significantly by Firefly model, so check with your dealer for specific pricing. Similarly, if you hear cracking sounds from the wood paneling around the display, stop immediately to avoid costly interior repairs.

Consider professional assistance if you're uncomfortable with the electrical aspects or if your Firefly system is integrated with other RV systems like solar controllers or battery monitors. Some installations have complex wiring that requires specific disconnect procedures, and a mistake could affect multiple systems in your Discovery LXE.
