Onan 5500 Generator Problems: Complete Repair Guide 2024

Spent three hours testing my 2014 Hurricane's Onan 5500 gen getting 11.8 volts output when every manual says it should be 12+ volts! Here's the weird part - when I disconnect the remote harness, the generator fires right up and purrs like a kitten. But the second I plug that remote connection back in, boom - both the remote start light AND the generator start light come on, and then... nothing. Won't start at all.

The really bizarre symptom is this chattering from the fuel pump when the remote is connected. I can literally feel the fuel line jumping around when I put my hand on it. It's like the pump is having some kind of seizure or something!

I'm guessing this has to be some kind of electrical issue between the control board and the remote system, but I've never seen anything quite like this before. Anyone dealt with this specific combo of symptoms on an Onan 5500? Really hoping there's a known fix because pulling this thing out of the RV again would be a major pain! …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

Norcold N842IM 'No CO' Error Fix - Complete Propane Troubleshooting Guide

Apparently everyone has a different theory about my Norcold N842IM's 'No CO' error—my neighbor swears the propane tank's empty, the RV dealer blames the thermocouple, and YouTube insists it's just dirty burners. The fridge works absolutely perfectly when we're plugged into shore power and running on AC - no problems whatsoever with cooling performance or any error codes.

The real problem starts when we disconnect from shore power and head out on the road. The refrigerator switches over to propane mode without any issues initially, and everything seems to be working normally for the first several hours. However, after approximately 8-9 hours of running on propane, I consistently get an alarm and a 'no CO' error code displayed. I've been turning the refrigerator off for about an hour (though I'm not sure if that's the right amount of time), and when I restart it, it runs fine for another 8-9 hour cycle before the same error occurs again.

I'm wondering what could be causing this specific 'no CO' error to appear after this consistent timeframe when running on propane. Is this related to combustion problems, ventilation issues, or something with the propane system components? I'd really appreciate some guidance on what I should be checking and how to properly troubleshoot this recurring problem. …more

RV Model Year vs Chassis Year: Understanding the Difference (It's Normal)

This is my first RV and the title says 2019 but the chassis paperwork shows 2018 - something feels off here. I bought what I thought was a 2024 Tiffin Allegro Open Road, but when I got home and went to register it, the VIN shows it has a 2022 Ford chassis. The DMV registered it as a 2022, which means I've instantly lost two years of value!

I'm trying to figure out if this is normal in the RV industry or if I got taken advantage of. The dealer sold it as a 2024 model, but now I'm wondering if this kind of mismatch between the RV model year and the actual chassis year is standard practice. I've invested a lot in this RV and really hope there's a reasonable explanation for this discrepancy.

Can anyone explain if it's typical for RV manufacturers to use older chassis for newer model year RVs? I want to understand if this is legitimate or if I should be concerned about deceptive practices. …more

Onan 4000 Generator Won't Start Without Choke: Code 14 Troubleshooting Guide

Halfway through another camping trip and trying to decide between babying my Onan 4000 with manual choke every startup or finally fixing this Code 14 nightmare. Let me try again:

Just found out that my 2013 Thor Class C's Onan 4000 generator won't cooperate after sitting since March, and I'm dealing with a nightmare. Been getting Code 14 errors and spent half the morning just trying to get it fired up.

The only way I can get it started is by manually messing with what I think is the choke linkage - otherwise it just won't go. Once I shut it off, same story - won't restart unless I physically manipulate that linkage again. Only has 240 hours on it and was serviced about 2 years ago.

I'm pretty sure the carburetor is gummed up from sitting, but what exactly does Code 14 mean? And more importantly, what do I need to clean to get that choke working automatically again? I really need to get this thing running properly before our next trip! …more

How to Replace Onan 10KW Generator Isolation Mounts: Complete RV Repair Guide

My 2013 Tiffin Allegro Bus generator (model 10HDKCA11506E) is producing violent shaking and a grinding noise that's absolutely driving me insane. The isolation mounts keep wearing out way too quickly - I just had them replaced 19 months ago and they're already shot again.

Last repair used parts #402-1680-02, but my Onan parts manual shows I should have 2x #402-0728-01 and 2x #402-0728-02 isolators. The generator only has 34 hours since the last mount replacement, and symptoms are obvious - excessive noise, vibration throughout the coach, and the oil drain plug hanging below the frame.

What's the proper way to replace these mounts? Are the parts I'm seeing actually interchangeable, or did the shop potentially use incorrect components? I'm tired of this recurring problem and need a solution that will actually last. …more

Dometic RV Fridge Won't Ignite Gas Mode: Quick Fix Guide

Pulled out my entire toolbox and I'm determined to fix this stubborn Dometic RV fridge that won't ignite in gas mode myself — where should I start? The thing works absolutely flawlessly when it's set to AUTO mode - switches from electric to gas without any issues, ignites on the first try, everything's perfect.

But here's where it gets maddening: the moment I manually switch it to gas mode, it completely refuses to ignite. I can hear the gas valve cycling on and off, but the ignitor just won't fire. It tries a few times then gives up and throws the CHECK light. I've been troubleshooting this for weeks and I'm stumped - why would AUTO mode work perfectly but manual gas mode fail every single time?

I'm really hoping this is something fixable because everything else about this fridge works great. Has anyone experienced this weird AUTO vs manual gas mode issue before? What should I be looking at? …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

Transfer Switch Ground Wire Not Connected - Winnebago View Fix

Nobody expects to find their 2021 Winnebago View 24D transfer switch ground wire completely disconnected at 11 PM when you're supposed to leave tomorrow morning. While replacing a damaged shore power cord, I opened up the transfer switch box and discovered that the main coach power ground wire isn't connected to anything - it looks like it was just cut short with barely any copper showing.

The RV has been this way since we bought it new, and I've never opened this box before. I'm wondering if this could somehow be intentional (maybe related to how the inverter is wired?) or if this is a serious problem that needs fixing right away. Should I be concerned about safety issues, and is this something that typically happens at the factory?

I'd really appreciate some guidance from more experienced folks - I want to make sure I handle this correctly and safely. …more

How to Add Electric Element to RV Water Heater While Keeping Anode Rod Intact

Three tools deep into this project and I'm determined to add electric capability to my Suburban water heater with cast iron tank myself — where's the best starting point? Problem is, most conversion kits I'm seeing want to replace the anode rod port with the heating element. That seems like a bad idea for a cast iron tank - pretty sure I need that anode rod to keep things from corroding, right?

Anyone know if there are kits out there that let you keep the anode rod? Maybe something that goes in the drain port instead, or one of those combo deals where the element also acts as an anode? Just want to make sure I'm not setting myself up for a rusty mess down the road! …more

RV Spare Tire Check: Verify Size and Pressure Before Every Trip

Every time I crawl under my Class C RV I stare at that spare tire that's been hanging there for years collecting road grime — check or replace? I mean, it's there in the compartment looking all tire-like, but I'm wondering if there's stuff I should be checking?

I keep hearing horror stories about people getting stranded because their spare was useless when they actually needed it. Turns out this happened to me - I discovered my spare was the wrong size (245 75R16 instead of 225 75R16), which could have been a major problem during a blowout.

What's the smart move here for spare tire maintenance? I learned to check not just the tire size, but also the air pressure. Mine was sitting at just 58psi, which thankfully I could fix with my air compressor.

I'd hate to be that person calling for help on the side of the highway! Anyone else have similar experiences? …more

Winnebago EKKO Shore Power & Water Leak Fix - Expert Guide

After discovering shore power and water leak issues in my brand new 2025 Winnebago EKKO, I'm trying to decide between returning it or tackling the repairs myself. First, when I connect to shore power, the batteries aren't charging at all and there's an 'OPEN GRD' warning on the transfer switch. The shore power connection shows a red G light with green L and N lights. Second, there's water dripping right above the driver's seat coming from somewhere in the plastic overhead area between the left storage compartment and the TV mount. We have a cross-country family trip planned next month and I need to know if it's safe to travel with these problems. The battery issue is preventing me from running the generator when the coach battery gets too low. Is this something I can fix myself or do I need to head straight back to the dealer? …more

Ford F-53 P0581 Code: How to Fix Cruise Control High Voltage Error

Planning to tackle this P0581 cruise control high voltage error on my 2007 F-53 chassis myself — got my tools ready, just need to know where to start. Already replaced brake switch, steering wheel switches, checked all fuses and wiring from dash to ECU. Horn works fine so clock spring seems okay.

Here's the key finding: disconnected the steering wheel connector completely to eliminate all external switches. Cleared the code and it stayed clear until I started the engine - then P0581 immediately returned.

Since the code sets with switches disconnected and all external wiring checks out, does this confirm an internal PCM problem? Looking for confirmation before spending money on ECU repair. …more

Complete RV Lithium Battery and Solar Setup Guide for Trolling Motors: Safe Installation Tips

Wondering if my 8-year-old lead acid trolling motor batteries that are barely holding a charge anymore are worth repairing or if I should upgrade to lithium? I need either a 24V or 36V lithium battery system, but I keep reading horror stories about people using the wrong chargers and damaging expensive lithium batteries.

I'm particularly worried about the charging setup - both for shore power charging at the marina and solar charging when I'm anchored out. I've heard you absolutely cannot use regular lead-acid chargers with lithium batteries, but I'm not sure what type of chargers I actually need. And for solar, someone mentioned something about MPPT controllers being required?

What specific type of chargers do I need for 24V and 36V lithium trolling motor batteries? I want to make sure I get the right equipment and don't fry a $1000+ battery pack. Are there particular lithium battery brands that are more reliable and safer than others? …more
