@CRM, if your are experiencing low water pressure when NOT connected to city water, but using the water pump to draw from the fresh tank, then check the filter on the input to the water pump. I recently was investigating an issue where the pump would not draw water from the fresh tank. Upon checking the filter at the input to the pump, I found it clogged with a slimy residue (see attached photo. I removed the fine wire mesh from the filter housing and washed both with Dawn dish detergent. Water flow is much improved with a clean filter.

@Cort, I second the recommendation of @Geronimo John to add ventilation fans to improve the operation of the Norcold 3-way refrigerator. This is not a difficult project. Also, I had little problem routing the fan control to the front cabinet, immediately behind the control panel. Feel free to send me a PM if you have questions. See:

@Leftwinger, I missed seeing your request for an article on the installation of the 4 pin wiring harness to provide lights for our rear mounted cargo carrier. I have not gotten around to writing the article. However, if you still would like the details, send me a PM and I will respond. Regards, Don

@johnwen, you are correct- yellow is ground and red is 12VDC. I believe you were referring to the image below: Please note, I later relocated the fan control to the upper storage cabinet above the refrigerator and microwave oven. The power connections for the fans remained unchanged from what is shown above. Regards, Don

@Geronimo John, the airflow around the fans is unobstructed. I suspect what you are seeing is the sloped interior wall above the refrigerator covered in aluminum tape. The fans do pull outside air into the lower vent and out the upper vent, where they are mounted. The flow of air is noticeable and I usually have them running at 50% of max speed, or less. The two fans easily produce sufficient airflow to significantly improve the performance of the refrigerator. Don

@johnwen, The fans on our LEII mount to the inner edge of the flange around the vent opening. Not to the slanted panel inside the vent opening. There was no cutting of the fiberglass. In the three photos below you should be able to see the screw heads which clamp onto the edge of the fiberglass. There are also small metal "ears" fastened with hex screws to the fan frame. The combination of the "ears" and the large screw head serve as a clamp. The fans are quite secure using this mounting mechanism. Regards, Don

@ThomB87, the fans are installed in the top vent. When they are running the movement of ward air from the upper vent is noticeable. There is very little fan noise. As @Ray Kimsey describes, only a 12VDC and a ground connection are required to run the fans. Attached to the fans is what looks like another wire, but is a temperature sensor. This is run down behind the regfrigerator. A small remote control panel is also attached to the fans with 5 or 6 feet of wire. I ran wires for the remote control up behind the main control panel near the entry door. There is an access hole behind the control panel, with a round cover. This is inside the forward most storage compartment above the refrigerator and microwave oven. I did not like having to remove the lower panel to access the fan controls. Also, the fan control has a bright blue LED which is visible outside the trailer if located behind the lower panel. Access from inside the trailer requires only opening the storage compartment and removing the round cover. This location also contains the annoying blue light on the remote control, which cannot be turned OFF.

@Nancy_D, we have a Norcold 3-way refrigerator and use it to freeze the blue freezer bricks. We typically use 6 bricks, in 2 groups of three and rotate the groups as needed to refreeze them. Typically this is a daily rotation. We have added supplemental fans mounted at the rear of our Norcold refrigerator, which make a significant improvement in the cooling capabilities of the Norcold refrigerator, especially when outdoor temperatures are high. If you encounter problems with you refrigerator, I recommend use considering the Beech Lane Refrigerator Fans The freezer bricks always refreeze overnight. I don't know exactly how long they take to refreeze, which will vary somewhat depending on the outside temperature and activity opening the door.

@Mountainman198 great idea? Could you please provide a link to the bins? I had no luck searching Target's website. Thanks, Don

@Ronbrink, good question, I don't know. I have not opened the Xantrex app at the time the Xantrex Inverter/Charger has been heard to come on. On Sunday, I put our trailer back into storage, probably until January, so I won't be able to check until our next trip. Although I have been told by both Oliver Service and Xantrex "not to worry", I am still curious as to the cause. Also, I have noticed the brief periods when the inverter/charger comes ON mostly during the night, when I am in bed. I have not, so far, been sufficiently motivated to rise and investigate these incidents. We are planning a January trip to the TX gulf coast in January to photograph migratory birds. I will try to remember to check the Xantrex app when I next notice the short interval of operation. Regards, Don

@Rivernerd, @Chukarhunter, @Steph and Dud B, @MobileJoy, @aaronorange, @John Dorrer, My issue has been resolved. The Xantrex Inverter/Charger is now charging my Lithionics batteries. As promised, following are the details leading to resolution of the problem. After logging a service ticket (including thorough details) with Oliver on Sunday, 11/12/23, I continued to read the Xantrex owner's manual and search the internet for clues to resolve the "AC bypass" preventing charging of the batteries. This effort was largely unsuccessful. On Monday morning, 11/13/23, I phoned Oracle Service to inquire if they could provide guidance to resolve the problem. In short, they could not. I was told since this was an AC problem, Oliver could not help resolve the problem. They recommended taking the trailer to a service center. In the course of the discussion, I was also provided erroneous information, such as the as the state of the ON/OFF switches on the Lithionic batteries. I was told the batteries are fully charged if the switch button is lighted a steady blue color. This is incorrect. The owner's manual from Lithionics clearly states a steady blue light indicates only that the battery is ON. I knew from using the Lithionics app on my phone exactly what the charge state was- between 10% and 12%. Oliver Service did forward my service request to Xantrex and I received an email from Xantrex which included a case number in their service request tracking system. In the automated email were instructions for submitting additional information. Using the Xantrex FXC Control app on my phone I made three screenshots of the current settings on the Xantrex inverter/charger, plus serial number, purchase date, etc. Below is one of the screenshots. Oliver Service also provided a phone number to Xantrex customer/technical support, ‭(800) 670-0707‬. I placed a call to Xantrex, only to receive a recorded message stating they were closed for a Canadian holiday. Today, I finally reached Shawn, a Xantrex tech support agent, after about a 25 minute wait in a phone queue. I provided the case number and Shawn spotted the screenshots and quickly reviewed the settings. Shawn told me he was almost certain my issue was caused by the setting of Charger Ignition Control being Auto-ON. While still on the phone with Shawn, I went to the trailer, opened the Xantrex FXC Control app and changed the setting of Charger Ignition Control to OFF. The Xantrex Inverter/Charger immediately came on and began to charge the batteries. Neither Shawn nor I can explain how this setting got changed from the default Oliver setting of OFF. In the two hours since changing this setting the batteries SOC has increased from about 10% to >40%, while connected to a 20 amp circuit. In another hour, the batteries are all near 80% SOC. Lessons learned- I had not checked all of the inverter/charger settings using the Xantrex FXC Control app against the Oliver default settings listed at https://support.olivertraveltrailers.com/portal/en/kb/articles/xantrex-inverter-settings. Had I done this, I may have resolved the problem sooner. In my opinion, Oliver Service should have recommended verifying the current settings against the Oliver default setting for the Xantrex Inverter/Charger and our model year trailer. I had ordered #10 AWG wire and components to add a 30 amp RV outlet to a utility building near our driveway. I am now reconsidering spending about $200 and several hours of labor to do so. The 20 amp circuit already in place seems adequate for our needs when we have the trailer in the driveway. This incident confirmed my prior observation- the lithium batteries can be recharged from a very low SOC to full charge in approximately 4-5 hours using a 20 amp circuit. I have also used this same circuit to run the Dometic air conditioner in the trailer for as long as needed. While I had Shawn on the phone, I asked him why the Xantrex Inverter/Charger would occasionally come ON for brief periods (2-3 minutes) while attached to shore power. I have noticed this occurring at night, such as when the furnace cycled on. Shawn said this was not unusual, if a large DC load is activated, such as a bilge pump, or a furnace blower. I hope this information is useful to other Oliver owners whose trailers are equipped with Xantrex Inverter/Chargers. My thanks to all who offered suggestions to resolve the problem. Regards, Don

I also encountered problems with air loss from Shrader valves which would not seat due to obstruction from balance beads. I suspect the problem affects more than 25 trailers. @AlbertNTerri indicated their hull number to be 1125. Our hull number is 990. As had been indicated by nearly everyone posting on this subject, Discount Tire has loyal customers for a reason. I have been doing business with them for over 25 years. I don't recall ever encountering an issue with their service, but do recall many occasions on which they exceeded my expectations. Fortunately, their nearest store is within 3 miles of our home.

@Rivernerd, thanks, I was aware I should not use a traditional charger designed for lead acid batteries to charge lithium batteries. I will certainly post on the advice I receive from Oliver Service, and the results. Don

@MobileJoy, I had overlooked setting 24, assuming that reducing the value for setting 28 (input breaker size) would result in lower charging current. Now that you have pointed this out, I will reduce the charging current to 15 or 20 amps. The symptoms I have observed lead me to suspect the inverter is trying to charge the depleted batteries at 150 amps, which is obviously not sustainable. Thanks very much pointing this out. Don

@Dave and Kimberly, it occurred to me that the current draw from significantly discharged batteries could be quite high, as you described. I have never tried to re-charge from such a discharged state. The most extreme case I recall was recharging from about 50% SOC after having the trailer in storage for a couple of months (placed into storage at ~50%, as recommended). I have tried changing the parameter 28 setting to 15 amps using the Xantrex app, to no avail. I hope to receive a call from Oliver Service tomorrow in response to the service ticket I logged. Thanks for the reply. Don
