  • Troubleshooting Curt Echo Brake Controller Not Sending Full Power with Manual Override
  • It sounds like you aren't correctly testing the brake output setting on your Curt Echo Wireless Brake Controller # C51180. What you need to be doing is driving 25 mph in an open parking lot and then applying your tow vehicle brakes with the brake pedal and then adjusting from there. Since you're starting off in a stopped position, applying the manual override, and then letting off the brakes, the Echo is likely getting confused because you had the brakes fully applied when you were at...

  • Troubleshooting Single Brake Assembly Replacement Getting Hot
  • Typically when it comes to breaking in a new self-adjusting assembly like the # AKEBRK-35R-SA the issue is weak braking and not too much braking or overheating. The breaking in process allows the brake shoes and magnet to seat into the drum. I would start by double checking the castle nut and make sure it is not overtightened. Hand tighten it and then back it off slightly. The other possibility is that your new brake assembly is doing all of the braking, hence the additional heat. It is...

  • Jensen Stereo JWM70A Won't Load DVDs
  • 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.

  • 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...

  • 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.

  • Trailair Rotaflex Pin Box Replacement
  • I reached out to my contact at Lippert and this pin box is not serviceable. Is there a chance you are using an autosliding hitch or something that might exert some leverage on that cushion area? The replacement pin box would be the Lippert # LC328330 (1621 Bolt Pattern - Rated 18K) Trailair pin box with rubber compound to absorb shocks. Another option is the Lippert # LC179879 Trailair Flex Air rated 18,000 pounds and 1621 bolt pattern with an internal airbag and a shock absorber to...

  • 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...

  • Out Of Stroke Error Code Clearing On a 2021 Grand Design Reflection Lippert Ground Control
  • If you are wanting to retract the front landing gear jacks all the way you should support the front of your 2021 Grand Design Reflection by either reconnecting to your truck or using some sort of stands for the camper to sit on. You will only have to manually raise the jack cylinder that has reached its stroke limit with the control pad and then clear the code. To clear an error code from the touch pad, repair or otherwise correct the issue, then press “ENTER.” If the error is still...

  • Troubleshooting Tail Light Issues on New Grand Design Trailer
  • Since you tested the tow vehicle's connector and know it's working properly, we can at least focus all our attention on the trailer side. It sounds like you've already done this, but it certainly sounds like there's some kind of ground issue on the Grand Design that's causing the dim lights, and now the issue on the left side tail light. Check once more to make sure all your ground connections, both the main harness ground for the 7-Way and each individual ground for the light assemblies...

  • 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...

  • 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...

  • 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.

  • 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....

  • 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...

  • Maxx Air Fan Lid Unable to Fully Open
  • It sounds like the lift arms aren't able to keep the lid up to the fan's fully-opened height. There are a few things that may cause this. You may have already tried this, but push the manual knob in when the you've reached the fully-opened position to engage the locking mechanism. If that doesn't solve the problem, there are some troubleshooting steps to take. First, check to make sure the bolts of the lift arms are fully tightened. If there are loose components, it may not be able to...

  • 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 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 Lippert Power Tongue Jack LED Lights Staying On With Switch Turned Off
  • Since this is a brand new jack you shouldn't be experiencing problems. I spoke with my contact at Lippert who said he hasn't heard of this being a very common issue and your best bet is a bad ground or a new switch. It is also possible that you could get the unit swapped out for a new jack if it is still under warranty. I recommend checking into that first. If the LED lights on your Lippert # LC285318 Electric Trailer Jack are still illuminating when the switch is off then you either have...
