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
Coleman Mach AC Fuse Blows With Battery On - Rockwood Fix

Coleman Mach AC Fuse Blows With Battery On - Rockwood Fix

Found out the hard way that the previous owner of my 2019 Rockwood Minilite 2509s left me with a Coleman Mach AC that blows fuses instantly when I flip on the battery. The AC fuse blows instantly when I turn on the battery disconnect, before the AC is even activated. The fuse literally blows before it's completely seated in the panel.

This began two weeks ago without warning - the system had been functioning normally prior to this. Initial fuse replacement provided temporary operation, but the problem returned on the next trip with the fuse already blown upon arrival.

Given the immediate fuse failure with just battery power connected, what type of electrical fault would cause this symptom pattern in a Coleman Mach unit, and what's the most likely location of the problem in the AC circuit? …more

Entegra Odyssey 26M Murphy Bed Couch Replacement and Ground Clearance Upgrade

Our 2022 Entegra Odyssey 26M's Murphy bed couch just completely failed at 11 PM and we desperately need a replacement solution before family arrives tomorrow morning. What if I could swap out that murphy bed couch for some fancy theater seats? I'm picturing myself reclining in luxury while Netflix loads at dial-up speeds thanks to campground wifi.

But here's where my engineering expertise (aka zero knowledge) kicks in - can theater seats even work with a murphy bed setup? Do the backs need to come off or fold down? And while I'm dreaming big, I'd also love to get a couple more inches of ground clearance so I stop scraping on every driveway entrance like I'm driving a lowrider.

Am I asking for the impossible, or is there actually a way to make this couch-to-theater-seat transformation happen? And what's the least complicated way to get this thing sitting a bit higher off the ground? …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

How to Fix Cracked Dometic RV AC Covers & Roof Vents: Complete Repair

Already tried following a YouTube tutorial to fix the cracked Dometic air conditioner cover on my 2022 East to West 1900MMK travel trailer but somehow made the crack even worse. What are my repair options - can I fix the crack or should I replace the whole cover?

Also dealing with a broken cap on the roof tank vent. I'm curious about material choices - I've noticed galvanized steel can rust, while PVC seems to degrade in sunlight. What are the pros and cons of different vent cap materials? What's a reasonable price range for replacement?

Looking for practical solutions for both issues. …more

How to Add Coleman Mach Heat Strips to RV AC Unit - Heat-Ready Control Box Installation Guide

Tried running my RV's electric heating this winter but it's eating through power way faster than it should, so I'm looking at adding Coleman Mach heat strips. I have a SportTrek Touring 272VRK with two AC units (Coleman-Mach 13.5k BTU and 15k BTU, models 48203-069 and 48204-069) with Cool-Only Control Boxes (model 8330-752) and I'm considering adding Coleman Mach electric heat strips, but I'm worried about a few things.

First, I'm concerned about whether my current AC units are compatible with heat strips - specifically the Coleman Mach 37203-4551 Electric Heat Kit/Strip. I want to confirm this will work with my existing 8330-752 control boxes. Second, I'm worried about the electrical load - I keep reading about heat strips drawing a lot of power and I'm scared of overloading my system or tripping breakers.

Most importantly, I absolutely do NOT want to lose the ability to use my existing Suburban SF-30FQ 30,000 BTU propane furnace - it's my primary heat source and I need that independence. I currently have 9420a381 digital thermostats controlling these systems, and I want to ensure I can maintain my current setup.

Is there a way to safely add Coleman Mach heat strips using some kind of Heat-Ready Control Box without compromising my furnace operation? I just want some reassurance that this can be done properly without creating problems. …more

RV Battery Disconnect Switch Guide: When to Use, What Loses Power & Staying Safe

Wondering if I can skip the $400 shop diagnosis for my electrical issues and just figure out this battery disconnect switch myself, even though I'm getting conflicting advice.

Specifically, I'm concerned about what happens to things like my LP gas detector, carbon monoxide alarm, and refrigerator when I disconnect the battery. Will I lose all my radio presets and clock settings? Are there certain situations where I absolutely shouldn't use the disconnect switch?

I want to use it for storage to prevent battery drain, but I'm also wondering about daily use scenarios. What are the best practices to avoid any problems or safety issues? I really don't want to mess anything up or put my family at risk. …more

Why Your RV Trips GFCI at Home But Not Campground: Complete Troubleshooting Guide

Turned on my motorhome at 11 PM and it tripped the home GFCI again — works perfectly at campgrounds but I need this solved before departure.

I've tried different adapters, rewired a busted GFCI inside the rig, even turned off ALL the breakers including the main panel breaker. Still trips my house GFCI every time, whether it's the garage, side of house, or front outlets. What gives? Why would it work everywhere else but trip GFCIs at home? There's gotta be something specific causing this, right? …more

RV Whirlpool Refrigerator Cycling Every 30 Minutes: Is It Normal? [202

Looked everywhere for answers on my Whirlpool residential refrigerator cycling every 30 minutes—my neighbor says it's normal, RV dealer says it's broken, YouTube says something else entirely. The ambient temperature here is around 65°F, and I have both the fridge and freezer set to the 3rd snowflake setting.

I haven't timed it exactly with a stopwatch, but I keep noticing it kicking on again after what feels like a short time. I'm concerned this frequent cycling might be a sign of a problem or could lead to premature failure. I try to keep the vents clean when I can access them. Should I be worried about this 30-minute cycle pattern, or is this within normal range for an RV refrigerator in these conditions? …more

RV 12V Auto Reset Breaker Size Guide: 30A, 40A, 50A Selection

Opened up my RV this morning to prep for our two-week cross-country trip tomorrow and the electrical system keeps tripping the breaker every time I run basic appliances! My RV's entire 12V system just died completely - no lights, no water pump, nothing. I've checked everything I can think of and I'm pretty sure it's the auto reset breaker that's failed.

I have a WFCO converter/charger setup with dual 6V batteries, but I can't get underneath right now to read what's stamped on the current breaker. I need to order a replacement but I'm not sure what amperage to get. I keep seeing 30A, 40A, and 50A options online but I don't want to guess wrong and either undersize it or waste money.

What's the typical auto reset breaker size for this type of setup? Is there a standard that WFCO usually pairs with dual 6V battery systems? …more

Lippert Power Gear Slide Motor Replacement: Complete Guide to Parts &

Walked out to prep our RV this morning and discovered our Lippert Power Gear slide motor is making grinding noises and won't extend properly. My RV's slide motor is failing and I'm trying to figure out the best way to get replacement parts. The slide is getting sluggish and I suspect it's either the motor brushes or possibly something in the gearbox itself.

I've been searching everywhere for Lippert Power Gear parts but I'm not sure where to look or what my options are. As it stands, the replacement parts are ridiculously expensive - a $100 gearbox, $50 brake, and $100 motor, but Lippert wants nearly $1000 for the whole assembly. I just want to replace the brushes, but they won't even sell those separately!

Can I buy just the motor component, or do I need to replace the entire gearbox assembly? I really need to know where I can actually purchase these parts and how to determine whether it's a motor issue or a gear problem before I spend a fortune on the wrong repair! …more

Southwire EMS Built-in vs External Surge Protector: Do You Need Both?

Opened my 2022 Holiday Rambler 38N DP and discovered it's eating through surge protectors way faster than normal, despite having the built-in Southwire system. Dealer says I might not need an external surge protector like a Watchdog since it's already built in.

Does a built-in Southwire surge guard provide the same protection as a standalone EMS unit? Should I still install an external surge protector or is the built-in system sufficient? Want to make sure I have proper protection without buying unnecessary equipment. …more

How to Safely Use Multiple RV Campground Pedestal Outlets: Electrical

How to Safely Use Multiple RV Campground Pedestal Outlets: Electrical

I looked at my campsite setup and realized I need to safely tap multiple pedestal outlets for my RV without creating an electrical disaster. My toyhauler is plugged into the 50A service, but I'm thinking about also using the 20A outlet on the same pedestal for my residential washer/dryer and an electric tankless water heater.

Specifically, I want to plug in an electric tankless water heater for my toyhauler's setup, but I'm concerned about whether a 20A outlet can even handle that kind of load. Are these outlets on the same breaker as the 50A service? I don't want to trip breakers or worse, cause any damage to the campground's electrical system.

What's actually safe to plug into those extra pedestal outlets when you're already using the main 50A connection? I'm being extra cautious because I've heard horror stories about RV electrical issues. …more

RV Red Fault Light No Power: How to Fix Partial Electrical Outage

Tried rewiring my RV's electrical system yesterday but something still doesn't seem right — red fault light is on and half my outlets have no power. My Class A has this red fault light glaring at me from the power panel, but it's not a total blackout situation. AC is running fine (thank goodness!), but my fridge, microwave, and some outlets decided to take a vacation.

I already tried the usual suspects - reset every GFCI I could find inside and messed with the main power cord panel outside where shore power comes in. Still got that annoying red light mocking me.

This partial power thing is driving me nuts. What should I be checking next to get everything back online? …more
