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

Dometic RV AC Not Cooling? 5 Common Fixes for Air Conditioner Troubleshooting Guide

Walked out to my RV this morning trying to decide between calling a repair tech or troubleshooting my Dometic Brisk Air rooftop AC myself since it's showing weird operational issues. The compressor engages and fan motor operates normally, but the unit fails to produce cold air output. Temperature differential across the evaporator coil is minimal.

Unit functioned properly through previous cooling season with no apparent issues. Current symptoms include normal airflow volume but inadequate cooling capacity. What systematic diagnostic procedure should I follow to identify the root cause? Looking for a methodical troubleshooting sequence that addresses the most probable failure points in order of likelihood. …more

RV Automatic Transfer Switch Dead: AC Power Fixes

Every time I flip the breaker, my 21-year-old coach's automatic transfer switch stays completely dead and I'm stuck with zero AC power. My Automated Engineering Corp ATS (model M10040A with M10041 display) is showing no AC on the LED readout even though shore power is definitely good.

I popped the cover off and confirmed power is getting TO the shore power terminals, but nothing's coming OUT to feed the AC system. Even manually pushed the contacts in and they stayed, but still no juice on the output side. Generator won't make it switch over either - it's like the whole transfer function is dead.

This thing has to be repairable right? Or am I looking at replacing the whole ATS unit? Really hoping someone has dealt with this before because losing AC in an RV is no joke! …more

Ford F53 V10 RV Chassis Repair Shops Near Raleigh NC

My Ford F53 V10 is showing misfire codes P0301 and P0303, but my compression test reads 180 PSI when everything says it should be around 150 PSI. I'm located near Raleigh, North Carolina, and I need to get some mechanical work done - specifically repairs to the exhaust manifold bolts and air conditioning system work.

The problem I'm running into is that when I call Ford dealerships in the area, they keep telling me they don't work on motorhomes, even though it's a Ford chassis. This seems crazy to me since the engine and drivetrain components should be the same as other Ford vehicles. The exhaust manifold issue and AC problems are fairly standard automotive repairs, so I don't understand why the Ford connection isn't helping me here.

What type of repair facilities should I be looking for instead? Are there specific shops or service centers near Raleigh that specialize in F53 chassis work, or should I be approaching this differently? I just need somewhere that can competently handle these mechanical repairs on my motorhome without the runaround. …more

How to Install a Lithium Battery Manager Relay in Your RV - Complete Guide

Got my weekend planned to install a lithium battery manager relay in my 1999 Fleetwood American Dream Saturday — what should I have ready beforehand? I understand these relays are crucial for protecting lithium batteries from overcharging by managing the connection to the alternator, but I want to make sure I understand the complete installation process before I start.

I'm looking for detailed information on how these battery manager relays function - specifically how they disconnect the batteries from the alternator when charging isn't needed. More importantly, I need step-by-step guidance on the actual wiring process, including how to properly connect the relay between my alternator/converter and the new lithium battery bank. I'm particularly concerned about getting the fusing right and understanding what control circuits are involved in this setup.

This is a significant electrical modification to my RV's charging system, so I want to ensure I have all the technical details covered before I begin the installation. Any comprehensive guidance on the complete process would be extremely helpful. …more

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Turned my compression tester on cylinders 5 and 7 and got 150 PSI readings, but I'm still pulling P0305 and P0307 misfire codes on my 2001 Ford E350 V-10. The engine runs smoothly overall, but the diagnostic codes are persistent.

I have replacement spark plugs and ignition coils available but want to ensure I'm following the proper troubleshooting sequence before investing time and effort. What is the recommended diagnostic approach for simultaneous misfires on cylinders 5 and 7?

Given that multiple cylinders are affected, should I prioritize certain components over others, or is there a systematic order that typically yields the most efficient resolution for this engine configuration? …more

Ford F53 Chassis Misfire Problems: Early Spark Plug & Coil Failure Solutions

Walked out to my 2021 Class A motorhome this morning facing the third Ford F53 chassis misfire this year and I'm done throwing parts at it blindly. We've got less than 20,000 miles on the odometer, but recently experienced rough running and got a check engine light. When I took it to a Ford dealer that services Class A rigs, they diagnosed misfires in two cylinders and recommended servicing the entire fuel system. I ended up having them replace all eight spark plugs, plug wires, and ignition coils since we were already dealing with failures.

The coach now runs better than it ever has since new, which makes me think the original components may have been subpar from the factory. What's really bothering me is that we shouldn't need major ignition system work this early in the vehicle's life. I'm curious if other owners of 2021 or newer F53 chassis motorhomes have experienced similar premature failures with their spark plugs, ignition coils, and plug wires? Is this pointing to some kind of quality control issue with Ford's ignition components on these newer chassis, and should I expect better reliability from aftermarket replacements going forward? …more

Pace Arrow Zone AC Not Working - How to Fix Blinking Green LED Error Code

Noticed my 06 Pace Arrow is 18 years old and the dual zone AC's zone 1 is starting to completely fail with a blinking green LED — repair or replace? Zone 2 is working fine with a steady green LED on the control board, but zone 1 has this annoying blinking green LED that I'm pretty sure means something's wrong.

The thermostat isn't showing zone 1 anymore either. I'm thinking it's gotta be the control board since zone 2 is chugging along just fine with the same setup. Anyone know if a blinking LED definitely means the board is toast? And is there a way to test this without just buying a new board and hoping for the best? …more

RV AC Won't Start After Capacitor Replacement? 5 Easy Fixes

Standing here looking at my RV AC unit right now and I can see the brand new capacitor I just installed, but the entire system is stone cold dead. I have a 2012 King Aire 4584 and recently tried replacing the run capacitor on my rear A/C unit because it was only running for about two minutes at a time and the compressor was getting really hot.

Now I'm in a worse situation - the unit won't start at all, even after I put the old capacitor back in. I'm wondering if there are some basic things I should be checking that I might have missed? Could I have blown a fuse or tripped something during the replacement? The compressor was pretty hot when I was working on it.

I'm hoping there might be some kind of reset button or other troubleshooting steps I should try before calling a repair tech. Any advice would be really appreciated! …more

Ford V10 Multiple Coil Codes Driver Side: Diagnosis & Repair Guide

Somewhere under the hood of my 1999 motorhome's Ford V10 there's a complete light show of coil codes P0351, P0353, P0355, P0357, and P0359 blinking across the entire driver side bank. Power and ground tests at individual coils show normal readings, and visual PCM inspection reveals no obvious damage.

Given that all affected coils are on the same bank, I suspect this isn't a coincidence of multiple simultaneous coil failures. What are the most likely common failure points that would cause multiple coil codes specifically on one engine bank? Should I be focusing on shared wiring harnesses, common ground points, or PCM driver circuits before replacing individual components? …more

2001 Ford F53 Firewall Module Identification: GEM, ICM & Fuel Pump Driver Guide

According to my spring ritual of firing up my 2001 Ford F53 for camping season, that same firewall electrical module overheats until the black plastic housing cracks. Looks pretty well cooked!

The part number isn't readable anymore thanks to the heat damage, and my local Ford parts counter is stumped. It's definitely some kind of power module since it has that chunky heat sink attached. Anyone know what the common firewall modules are on these F53s? I'm thinking it might be something like a GEM or ignition module, but honestly not sure what I'm looking at here. …more

Onan Generator Won't Stay Running: Repair vs Replace

Three distinct sputtering sounds keep coming from my Onan generator that fires up perfectly but dies out after running for a while. Multiple service calls and repairs have been attempted, but the problems persist intermittently, making diagnosis challenging.

The repair costs are accumulating significantly, and I'm reaching a decision point regarding whether to continue troubleshooting or consider replacement options. What criteria should I use to determine when total repair investment justifies switching to a replacement unit? Are refurbished Onan generators a viable alternative, and what factors should guide this repair-versus-replace analysis for intermittent generator failures?

(Note: This is specifically about my RV's Onan generator, which I'm referring to as my 'Jenny'.) …more
