Norcold 1210 Not Cooling: No Error Codes Troubleshooting Guide

During my morning RV check I spotted my Norcold 1210 completely dead with zero cooling that was running perfectly yesterday with no error codes. Unit appears to be operating normally with no error codes displayed, but it's not cooling properly. Interior temperature is staying above 50 degrees. Thermistor has been tested and checks out fine. What else should I look at? …more

Ford V10 Triton Engine Maintenance Guide: EGR Delete vs Regular Service Tips

Spent years doing regular EGR maintenance on my old gas motorhome without issues — but this 2007 Fleetwood 31' Tioga with Ford V10 Triton has me second-guessing everything. I keep reading conflicting information about EGR delete procedures on V10 engines, and I'm worried I might make things worse if I mess with it.

Is the EGR delete modification actually necessary on this 2007 3-valve V10, or am I overthinking this? I don't want to void any warranties or create problems that weren't there before. Would I be better off just sticking to regular maintenance instead of modifications? I'm looking for reassurance that I'm taking the right approach to keep this engine running reliably for years to come. …more

RV Chassis Battery Draining & Dead Outlets - Troubleshooting

Finally followed the manual's advice to check the converter first when my outlets died, but my RV chassis battery keeps draining even though the converter tests perfectly. here and I'm at my wit's end with my 2018 Winnebago Vista. The chassis battery keeps going completely dead every few days, even when we're plugged into shore power at the campground. I've already replaced the battery twice thinking it was just old, checked all the obvious stuff like dome lights and radio, and even had the alternator tested - everything checks out fine.

What's really driving me crazy is that this just started happening about a month ago out of nowhere. We've been full-timing for three years without any major electrical issues. I'm wondering if there's some parasitic draw I'm missing or if the battery isolator could be acting up? Has anyone else dealt with this nightmare? I'm getting tired of jump-starting this thing every other day and my wife is about ready to sell the rig and get a travel trailer instead! …more

Ford E450 Inertia Switch Location Guide - Find Your RV's Fuel Cutoff Reset Point

Every Ford E450 I've worked on had the inertia switch behind the driver's panel — but my 2011 Freedom Elite 32r has it hidden somewhere completely different. The engine is experiencing what appears to be fuel delivery issues after a minor fender bender, and I suspect the inertia switch may have been triggered and needs to be reset.

I've already done extensive searching in the typical locations - removed both driver and passenger side kick panels completely, pulled out the glove box, and even partially disassembled sections of the dashboard. Despite checking all these common spots where Ford usually places these switches, I'm coming up empty-handed.

Could the switch be integrated into another component on this particular year and model? Are there any alternative locations specific to the E450 chassis or Freedom Elite configuration that I should be checking? I'm also wondering if some models of this year might not have a traditional standalone inertia switch at all. …more

Ford F53 7.5L RV Won't Start: Fuel Pump Relay Voltage Drop Fix

Woke up to my 1996 Ford F53 7.5L motorhome eating through my patience and wallet with this no-start issue that keeps coming back. It cranks strong but absolutely will not start, and I've been chasing this problem for weeks now. The engine ran fine for about 3-4 minutes one day, then just died and hasn't started since.

I've already done quite a bit of diagnostic work:
- Replaced PCM and distributor
- Fuel pump works when powered directly
- Battery is fully charged
- Checked fuses and relays
- PCM relay voltage drops from 12.2V to 9.3V with key on
- Fuel pump relay only shows 3.3V at pin 86 (should be 12V)
- Inertia switch tested at 1.7V at connector
- ANL 178 fusible link fluctuates between 0.3-0.6V

The engine will only start with starter fluid when the SPOUT is removed. I'm getting only 5.5V at the fuel pump connector.

Has anyone dealt with this specific issue on an F53 chassis? I really need to get this RV back on the road and I'm running out of ideas! …more

Dometic 12V Refrigerator Not Cooling on Battery Power - Complete Troubleshooting Guide

Staring at my Dometic DMC compressor refrigerator that runs perfectly on 12V DC when it's cool but stops cooling completely once temperatures hit 85°F or higher. The unit works perfectly when I'm plugged into shore power at campgrounds - everything stays cold and the freezer compartment keeps items frozen solid. However, when I'm boondocking and running solely on my RV's battery bank, the performance drops significantly. The refrigerator struggles to maintain proper temperatures, and the freezer can't keep things frozen.

I have a relatively new battery setup with what should be adequate capacity for my power needs. The batteries test fine with a multimeter when the refrigerator isn't running, but I'm wondering if there's something I'm missing about power requirements or electrical connections. I've heard that 12V compressor refrigerators can be pretty demanding on battery systems, but I'm not sure what specific issues to look for.

What are the most common causes when a 12V Dometic compressor refrigerator works fine on shore power but fails to cool properly when running on batteries? I want to troubleshoot this systematically before calling in a technician. …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

How to Remove Firefly RV Control Panel: Complete DIY Guide

Our 2019 Fleetwood Discovery LXE has a malfunctioning Firefly multiplex control panel that needs to be completely removed. I've been putting this off for months because I keep hearing horror stories about people cracking their panels or damaging the surrounding woodwork during removal.

I need to access the back of the unit for some electrical work, but I'm honestly terrified of breaking something expensive. The panel seems to be mounted flush with no obvious screws or clips visible from the front. I've searched everywhere but can't find a complete walkthrough that covers the preparation, actual removal process, and how to get everything back together properly.

Can someone please provide a detailed DIY guide that covers all the steps? I'm willing to take my time and do this right - I just need to know the proper technique so I don't end up with a broken control panel or damaged wall. …more

RV Inverter Beeping 3 Times Then Shutting Off: Complete Troubleshooting Guide

Standing next to my RV watching what started as occasional inverter beeps last month escalate into exactly three beeps and complete shutdown after just minutes. My multimeter shows the batteries at 12.8V when I check them, so they seem fine.

I'm worried there might be something more serious going on that I'm missing. Could this be a safety issue? What would cause an inverter to shut itself off like this even when the battery voltage looks normal? I don't want to keep trying to restart it if there's a risk of damaging the system or creating a safety hazard. …more

RV MPPT Solar Controller E1 Error Code: Causes & Fixes

Halfway through troubleshooting my MPPT solar charge controller's E1 error, the controller was working fine for months, but now it's completely stopped charging my batteries and just displays this E1 fault code on the screen.

From what I've read, this could be related to battery over-voltage conditions or possibly some kind of wiring fault, but I want to make sure I understand all the potential causes before I start troubleshooting. I'm comfortable doing basic electrical work myself, but I also want to know when this might be something that requires professional attention for safety reasons.

Can someone provide a detailed breakdown of what the E1 error specifically indicates, walk me through the proper diagnostic steps to identify the root cause, and explain the repair process? I'd especially appreciate guidance on how to safely approach this troubleshooting and what warning signs would indicate I should call in an expert instead of attempting the fix myself. …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

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

How to Test RV Door Magnetic Switch - Electric Steps Fix

Three steps this morning to my RV and noticed my electric steps weren't extending like they did perfectly fine yesterday. I've already verified that I have 12VDC at the 4-pin connector, and I even tried swapping in a different control module, but still nothing happens when I open the door.

Everything points to the door magnetic switch being the issue, but I'm honestly nervous about testing electrical components - I don't want to damage anything or create a safety hazard. Is there a safe way to test the magnetic switch with a multimeter? I want to make sure I'm doing this right before I start poking around with test leads. …more

RV Underbody Lighting Installation: Complete DIY Guide

I'm wondering if anyone else walked out this morning and spotted how embarrassingly bland their RV's underside looks compared to those slick LED setups online? My husband and I are pretty new to the RV world and I've been wanting to add some nice ambient lighting underneath our Class A motorhome. I think it would look really cool when we're set up at campsites in the evenings. I've seen other RVers with these gorgeous blue or white lights that make their rigs look so professional. We're definitely beginners when it comes to electrical work, so I'm hoping someone can walk me through what's involved. Is this something we can tackle ourselves or should we find a professional? Any product recommendations would be super helpful too. Thanks so much for your patience with us newbies! …more
