• Troubleshooting Lippert Ground Control 3.0 Experiencing Retraction and Power Issues
• With your Lippert Ground Control 3.0 # LC358590, since you have power to the unit confirmed and have already disconnected the touch pad and controller letting them remain disconnected for more than 15 minutes for reset, you will most likely need to replace the control module. This is the brains of the system and since you can manually retract we don't know the fuses are good so you will want to check them individually on that control module. 9 out of 10 times, replacing the control module...

• Troubleshooting Weak 12" Electric Brakes with Full Power Being Sent to Them
• It looks like you have the correct voltage to your Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA so I recommend re-checking the adjustment. You said they seemed to work but you didn't mention how much you had initially adjusted them. You want there to be a slight drag when you're spinning the wheel by hand without applying the brakes. It's possible that the brakes are strong enough that you can't spin them by hand with full power applied, but the weight and momentum of your...

• Troubleshooting A Furrion Vision S RV Camera System Monitor That Goes Black When Using View All
• I spoke with Furrion and found that this is a known issue with the wiring on the side marker cameras # FCE48TASL. A lot of people have been installing the trigger wire in with the power wire instead of running it to the turn signal or just capping it off. I've attached an installation video I did below where I show the wires for the cameras at the 6:18 minute mark. You'll want to remove the whole side marker camera from the trailer to get to the wiring and disconnect the trigger wire...

• Troubleshooting Trailer Brakes Damaged From Breakaway Pin Being Pulled and Sparks from Battery
• I'm really sorry to hear about the mishaps on your brand new trailer! When reading through your descriptions the first thing that comes to my mind is the possibility that there's an exposed wire somewhere along the trailer that's making contact with the frame. This is essentially powering the frame so that when you attach the ground cable it's creating those sparks (which is not normal). If this isn't the exact cause of everything, there's at least something going on with the factory...

• Why Is My Brake Fluid Coming Out Discolored When Bleeding the Brakes
• If the brake fluid that came out when bleeding the brakes after a disc brake conversion # HSE7K-TR1 came out discolored then there's a contaminant or water in the lines somewhere. The only way to clear it out would be to run more fluid through it to pass all of the contaminant out. You'll want to bleed the brake assembly furthest from the actuator first and work your way closer to the actuator.

• Stabilizer Jack Troubleshooting For 2018 Grand Design Solitude Fifth Wheel.
• Ok for hydraulic jacks that have a mind of their own you will need to do a bypass test first. Retract jack in question. If retracting hydraulic landing gear, HLG, both jacks will retract. If retracting leveling jack, all jacks will retract. Once jack is fully retracted, remove the extend hose (hose located at the top of the jack). If testing ROAD SIDE HLG or REAR STAB JACKS, the hose will be mounted to a red restricted flow valve block. At this point DO NOT attempt to extend the jacks....

• Do Old Furrion Vision S Cameras have to Be Unpaired to Pair to New Cameras
• The good news is you don't have to unpair from cameras that don't have access to any longer and would only need to pair the monitor to new cameras. On the menu of the Furrion Vision S system scroll to pairing and then select rear camera. It should find the camera but if not go back to the camera and find the pairing button on it and hold it down.

• If your Jensen RV Stereo # JWM70A will not load DVDs, and you are sure they are not damaged in any way, then there is an internal issue with player. The stereo has a 1-year warranty, but if that has expired you will need to get a new Jensen RV Stereo # JWM70A.

• Brakes Engage On Grand Design Momentum While Hooked Up To Shore Power
• The shore power circuit for your trailer should not have anything to do with the trailer's brakes as they are on completely different circuits and use an entirely different type of current (AC vs. DC). However, if you have a short on the AC power circuit and the circuit is sending power to the trailer frame/body which is commonly referred to as "Hot Skin" then that could then cause the brakes to engage via the ground wire. Therefore, I recommend you disconnect shore power and see if the...

• Troubleshooting Installation Of Furrion Side Maker Cameras On A 2021 Grand Design Momentum 350G
• I would first start by turning your running lights on and using a circuit tester # PTW2992 check which wire (black or white) is your power. From my experience you can't always just go off of the standard wire color for power/negative as manufacturers love to complicate things. Once you know which wire is your power you can wire the Red and Brown wires from the LED Marker Light RV Side Cameras w/ Night Vision for Furrion Vision S Systems # FCE48TASL to it and the black to the ground wire....

• Replacing Fan Motor on Trailer Vent with MA10-20270
• I checked with the manufacturer and the tiny screw you're seeing is a set screw. You will use an Allen wrench/key to remove this. I'm attaching a picture with a set of installation instructions for you to refer to when you're replacing the MaxxFan Lift Motor # MA10-20270 . We don't have the new/updated instructions available, but where it refers to a nut holding the blades on to the motor shaft, this is now a set screw like you're seeing. All of the other steps will remain the same.

• Troubleshooting MaxxFan Not Opening on 2017 Grand Design Reflection
• It looks like you have the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan - Powered Lift - 4 Speed - White # MA00-04751KSX. The unit sounds like it is malfunctioning and this could be due to the rain sensor # MA34FR. It sounds to me like the sensor is seeing moisture whether there or not and keeping the power lid from opening. I recommend unplugging the rain sensor and seeing if all the other functions work. If so, then simply replace that sensor. If the other features still do not work,...

• Troubleshooting Auto-Level Failure With A Lippert Ground Control 3.0 Leveling System
• It sounds to me like you need to reset your Zero Point Calibration of your Lippert Ground Control 3.0 Electric 5th Wheel RV Leveling System # LC358590. This is a common issue and Lippert recommends raising the front of the trailer just a bit above level when rolling through the manual leveling steps in the Zero Point Calibration routine. I've attached the steps below for you: 1. In manual mode, run the jacks to level the trailer. This is best achieved by placing a level in the center of...

• Troubleshooting 2022 Grand Design Solar Kit Not Working After Adding Batteries
• Yes, you should have a fuse between the battery bank and each of the following: - Solar Charge Controller - Inverter - Converter I'm attaching a clip from the instructions for the Go Power Weekender Solar Charging System # 34282183 that you can check out. Be sure that you have your new batteries connected to your battery bank the right way. If you connect them in Parallel then that keeps the Voltage the same but if you connect them in Series it increases the Voltage. It's also worth...

• Ground Control 3.0 Touchscreen is Blank
• If your touchscreen with the Ground Control 3.0 leveling system is blank but has power, try doing a reconfiguration or reset by pressing the home (silver) button five times. If that does not work it sounds like there is a malfunction within the remote and it will need to be replaced with the Replacement Touchscreen Remote with Charger for Lippert Ground Control 3.0 Electric Leveling System # LC358601.

• Is There A Way To Move A Pin Box Higher On The Mounting Ears On A Grand Design Momentum 399TH
• I do not recommend enlarging the holes to move the pin box up higher since it takes a lot of pressure and will most certainly move up when you hit a rough patch of road and end up pinching the trim. You would need to cut out the trim and walls around the pin box to allow for the pin box to go higher or try to offset the increased height. You can try lowering the 5th wheel hitch 2" to level the trailer back out or try raising the suspension with the Correct Track Trailer Alignment and Lift...

• Troubleshooting A Furrion Tankless Water Heater That Turns On When The Toilet Is Flushed
• What you're saying leads me to believe that the water line running to the toilet may branch off of the hot water line. This is not correct but sadly isn't uncommon. I discovered when remodeling one of the bathrooms in my own home that the builder had the water line for the toilet connected to the hot line instead of the cold. I recommend tracing those water line from the toilet to make sure that it's not connected to the hot side and calling for hot water every time you use it. This would...

• Where Are The Fuses Located For The Legs Of The Ground Control 3.0 Leveling System
• The fuses for the legs of the Lippert Ground Control 3.0 Leveling System # LC358590 are located on the control module # LC304136. You can test/replace the fuses here to restore power to the legs. I will also say that the system as a whole requires 12.75 volts to properly operate so you could also be having an issue because the battery is a bit low.

• Troubleshooting the Replacement Cup Holder for Thomas Payne
• To operate the lights on the Cup Holder for Thomas Payne Momentum Recliners and Sofas # 195-387597 you just use the button found on the outer ring of the cup holder (be sure that it is not locked). If when the lights are off, the system is still lit (other than the small spots on the buttons) you likely have a malfunction and will want to unplug the chair to reset it. If that doesn't solve the issue, then the switch is bad and you will need the Replacement Cup Holder for Thomas Payne Momentum...
