RV Electrical Problems: 12V & 120V Troubleshooting Guide 2024

Around $500 in parts later — replaced the main breaker, cleaned all connections, checked the transfer switch — my 2007 Holiday Rambler Admiral SE still won't recognize shore power.

I'm pretty sure 110V is making it to the rig since I can measure it, but somewhere between the plug and my appliances, something's not happy. Energy management panel is dark too. What's the logical troubleshooting order here? I keep hearing about transfer switches and breaker panels but honestly don't know where to start without making things worse! …more

RV Inverter Guide: Modified vs Pure Sine Wave - Safe Power

My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

RC7-GS Inverter AGM Battery Settings: Complete Setup Guide

Replaced my 105Ah AGM battery and now my RC7-GS inverter charger is completely rejecting it like this capacity doesn't exist in its programming.

The charging settings only go from 125Ah up to 1000Ah, with an 'auto' option that supposedly 'learns' my battery but resets every time the low voltage cutoff trips (which feels like cheating, honestly). I'm worried about undercharging or cooking my expensive new AGMs if I pick the wrong setting.

Oh, and while we're talking about things that don't work as advertised - the generator auto-start feature might as well be a myth. Can't even manually start the generator from the RC7 panel. At this point I'm wondering if I should have just stuck with my old setup that actually worked! Anyone know what I'm doing wrong here? …more

Atwood GC10A-4E Replacement: Best Tankless RV Water Heater Upgrades 20

Halfway through draining my Atwood GC10A-4E's supposed 10-gallon capacity, the water's already running cold but my gauge shows I've only pulled maybe 6 gallons. Are there any dual-fuel tankless units that would work as a replacement? I know there's no plug-and-play option, but what are the best tankless water heaters that offer both gas and electric operation for RVs? …more

RV DC Electrical System: Expert Guide to 12 Volt Systems

Opened my RV this morning to find the 12V system going haywire — lights dimming randomly, fans slowing down, and the inverter shutting off despite full batteries.

Specifically, I need to understand the fundamentals of RV batteries - different types, proper sizing, charging requirements, and maintenance. I'm also confused about DC wiring best practices, what gauge wire to use for different applications, how to properly route and protect circuits, and where fuses and breakers should go. Voltage monitoring is another area where I'm lost - I see all these battery monitors and don't know what I actually need or how to interpret the readings.

I'm also planning some system upgrades down the road like adding solar or upgrading to lithium batteries, so I'd love to understand how all these components work together and what I need to consider for future modifications. Is there a comprehensive resource that covers all aspects of RV DC electrical systems from batteries and wiring through monitoring and upgrades? …more

Best RV Thermostatic Shower Mixing Valves 2024 - Installation Guide

According to my screaming every morning, there's this scalding burn followed by an icy shock sensation hitting my back in my RV shower. There's no middle ground - it's like my water heater has anger management issues.

I'm shopping for a thermostatic mixing valve to save myself from daily temperature shock therapy. I keep seeing mechanical models like the Symmons Temptrol and Phoenix PF213200, but honestly have no idea if they're any good. And don't get me started on those fancy digital ones like the Kohler DTV+ - they look amazing but I'm guessing they're about as RV-friendly as a pet elephant.

Anyone know which thermostatic valves actually work well in RVs without requiring me to rewire half my rig or sacrifice my firstborn to the plumbing gods? …more

RV Refrigerator Ammonia Smell: Leak Repair & Safety Guide

Last spring when I opened up my RV for the first camping trip, that same overwhelming ammonia stench hit me the moment I cracked open the refrigerator door. It seems to be getting worse and I can smell it throughout the coach now. I'm scared this might be some kind of refrigerant leak but I'm not sure.

Is it safe to keep using the refrigerator? Should I be concerned about health risks from breathing this in? I don't want to make the situation worse or put my family in danger. What should I do immediately to stay safe? …more

How to Upgrade Progressive Dynamics Converter for Lithium RV Batteries Safely

Got a 15-year-old Progressive Dynamics converter that's starting to throw fault codes with my new lithium setup — worth upgrading or try making it work? I have a 2006 Lance 915 cabover that I recently upgraded with 2-200 watt Bouge solar panels and 2-100ah SOK lithium batteries.

The problem is I'm still running the original Progressive Dynamics converter charger that came with the RV, and I've learned it's not designed for lithium batteries. I'm worried about damaging my new battery investment.

What are my options for upgrading? I'm not sure if I need to replace the whole converter unit or if there's some kind of upgrade kit available. Any advice would be really appreciated since I don't want to mess this up! …more

How to Upgrade Your RV Converter Charger for Lithium Batteries with Gentle Care

Halfway through planning our three-week cross-country trip next month, I realized my PD4560 60-amp converter/charger won't properly handle the lithium batteries I'm installing. My existing Progressive Dynamics unit obviously isn't designed for LiFePO4 batteries - I can use boost mode to charge them up, but I know that's not ideal for battery longevity.

I just purchased a 30 amp generator and I'm wondering if it will have enough capacity to handle not just my current charger, but potentially a larger lithium-compatible unit. I'm considering upgrading to a 75 or even 90 amp charger to reduce charging times, but I need to make sure my generator can handle the load. I'm trying to figure out the actual AC amp draw of these higher-capacity chargers and whether my 30 amp generator will be sufficient.

What are the best lithium-compatible converter/charger options that would work with my generator setup, and how do I properly size the charger capacity to match my lithium battery bank? …more

RV 3-Way to 12V Compressor Fridge Replacement: Cut Power Use 80%

Three weeks into owning this RV and the previous owner left me with a power-hungry Norcold 3-way absorption fridge that's absolutely demolishing my 600AH battery bank daily.

I keep hearing people rave about switching to 12V compressor fridges like the Dometic DMC4101, claiming they'll solve all my power woes. But here's the thing - everyone says "it uses way less power" but nobody gives me actual numbers! I need the cold hard facts: exactly how much power will I save making this switch? Will it really make that big of a difference, or am I just trading one expensive problem for another?

Please tell me someone has real-world experience with the power consumption difference between these fridge types! …more

RV Water Heater Not Hot Enough: Fix Lukewarm Water Issues

Looked forward to our two-week cross-country trip starting tomorrow until I discovered my RV water heater that used to produce scalding hot water now barely gets lukewarm. Both the electric and gas functions appear to be working - I can hear the gas igniting and see the electric indicator light - but the water temperature just won't get hot enough for a decent shower.

I've been dealing with this for weeks now and it's driving me crazy. The water gets warm, but nowhere near the hot temperatures I used to get. Is this a common problem with RV water heaters? What are the most likely culprits when you're getting lukewarm water instead of hot? I really need to figure out what's causing this and how to fix it before my next camping trip. …more

RV AC Making Loud Humming Noise? Fix Compressor Not Starting

Somewhere above my head, there's this loud, relentless humming grinding through the RV whenever I flip on the rooftop AC — compressor won't start but the fan spins fine.

I've been dealing with this for days now and it's driving me crazy - especially with the heat we've been having! The humming is so loud that I'm worried something might be seriously damaged. I really hope this is something I can fix myself rather than having to call out a repair tech. What could be causing a compressor to hum loudly but not start up? …more

MagnaSine MS2012 Inverter Replacement Guide - Best Upgrade Options 202

About my 2007 Fleetwood Bounder: the MagnaSine MS2012 manual claims it should handle my loads perfectly, but this inverter keeps failing on me anyway. It's been acting up for months now - the microwave keeps causing it to hiccup and shut off, then it comes right back on. I know it's only going to get worse from here.

I've been looking at upgrading to something more reliable, maybe a Victron or another brand, but I'm honestly overwhelmed by all the options out there. What are the best replacement inverters that other RVers have had success with? I just want something that's going to work consistently without all these random shutdowns.

Before I spend a bunch of money though, could this actually be a battery issue instead of the inverter itself? I'd hate to replace a perfectly good unit if the real problem is somewhere else in the system. …more

Georgetown GT7 Lithium Battery Conversion: Complete RV Installation Guide

Turned the keys on my 2023 Georgetown GT7 and discovered the previous owner left the electrical system in complete shambles, now facing this intimidating lithium conversion nightmare. I know I need LiFePO4 batteries, but every forum post I read mentions different components and I'm getting conflicting information.

I really want to make this upgrade work - the lead acid batteries are killing me with their weight and charging limitations. What specific components do I need beyond the actual lithium batteries? I'm especially confused about whether my converter will work and if I need additional charging equipment for the alternator. Please tell me my 2023 model year gives me some advantage here! …more

Samsung RF18 Refrigerator Installation Guide: Bounder 35E RV Door Opening Dimensions

Apparently I'm tackling my Samsung RF18 residential refrigerator install in my Bounder 35E this Saturday — what measurements and prep work do I need ready for the door opening? I've measured the door opening and it's just barely larger than 24.5 inches at the narrowest point, and Samsung lists the RF18 at exactly 24.5" wide with doors removed.

I'm worried I might get the refrigerator delivered and then find out it won't actually fit, or worse - damage something trying to force it through. Has anyone successfully done this installation? I know some people remove windows for residential fridge installations, but I really don't want to go that route if I can avoid it. The measurements seem so close that I'm concerned about whether this is actually feasible or if I'm setting myself up for a costly mistake. …more
