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

How to Protect Your RV Alternator When Charging Lithium Batteries: DC-

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more
Everchill 12V Fridge Not Cooling But Freezer Works - Fix

Everchill 12V Fridge Not Cooling But Freezer Works - Fix

The freezer in my 2024 Jayco Eagle's Everchill 12V fridge works perfectly, but I'm tackling the non-cooling fridge section this Saturday — what should I check first? The Everchill 12V four-door refrigerator/freezer unit has developed what seems to be a common problem - the freezer compartment is working perfectly and maintaining proper temperatures, but the refrigerator section has completely stopped cooling.

I've verified that the internal fan is running normally, so it's not a power issue. The unit gets power, the controls light up, and I can hear it cycling on and off as expected. However, despite the fan running and the freezer working fine, the fridge compartment just won't get cold anymore. This seems like it happened suddenly rather than gradually losing cooling capacity.

I've read online that this is a known issue with these Everchill units, but I'm not sure what specifically causes the freezer to work while the fridge fails. What are the most likely culprits when you have this exact symptom pattern, and what should I check first to diagnose whether it's something I can fix myself or if I need to call for warranty service? …more

Norcold N7LX.3F Running Too Often: Complete Troubleshooting & Repair Guide

Standing in the RV supply store staring at replacement thermostats and control boards with no clue which one will actually stop my Norcold N7LX.3F from running constantly. It's been running way more frequently than it ever has before, and I can't figure out what's wrong. The cooling seems off too - items aren't staying as cold as they should be.

I've already checked the obvious stuff like making sure the vents aren't blocked and the unit is level, but something is definitely not right. The fridge just keeps cycling on and off constantly, which has me worried about both the power consumption and whether there's a bigger problem developing.

What should I be looking at to diagnose cooling efficiency issues? I really need to get this sorted before our next camping trip! …more

RV Refrigerator Freezing Everything: Fix Temperature Control Issues Fast!

Our RV refrigerator has completely lost its mind — it's turning our milk into ice blocks and freezing our lettuce into green popsicles. Even cranked to the "warmest" setting, this thing treats everything like it belongs in the freezer section.

The freezer compartment is working perfectly normal (of course), and I've already checked the thermistor which seems fine. But clearly something is controlling the temperature wrong because I'm pretty sure my eggs shouldn't require an ice pick to crack open.

What actually controls the main fridge temperature in these rolling iceboxes? I need to figure out what's making my refrigerator think it's auditioning for a role in Frozen. …more

How to Install Norcold N821 Power Board Kit 633292 - Complete RV Repair Guide

Finally replaced the power board on my N821 fridge with Norcold kit 633292 yesterday but something still doesn't seem right. this thing came with zero instructions! Apparently it's some kind of universal kit that works on multiple applications, which sounds great in theory but leaves me scratching my head about the actual wiring.

My fridge is from a 1999 rig with one of the lower serial numbers (the early version), and I'm hearing that makes a difference in how this gets connected. Anyone know how to figure out which wiring configuration I need for this specific setup? Really don't want to fry anything by guessing! …more

Norcold N611 NO CO Error Code: Complete Repair Guide for Flashing Warning Lights

Staring at my 2007 Norcold N611's flashing NO CO lights shutting everything down — is there a DIY fix under $50 since I can't swing a $300 service call? The fridge loses cooling and then locks out completely. I can reset it and it works for a few days or weeks, then the same cycle repeats.

What exactly does the NO CO error code mean and what causes it? Need to understand what's happening before I start throwing more parts at this problem. …more

1986 Fleetwood Jamboree Fridge Repair Guide + Ford 460 Engine Upgrade

Got my third fridge failure this season in my '86 Fleetwood Jamboree with the Ford 460 carbureted engine and I'm done guessing what's wrong. Two main issues:

The fridge isn't working at all. What should I check first for troubleshooting?

Also considering an EFI conversion on the 460 for better fuel economy since gas mileage is brutal. Is this upgrade cost-effective or should I stick with maintaining the carburetor system? …more

RV Fridge Not Cooling Properly? Fix Intermittent RV Absorption Fridge Issues Fast

About 7 years ago leveling fixed my old Dometic's cooling issues — but this Maybe-Cold N8X (Serial 28221668) absorption fridge has me completely stumped. This thing is driving me absolutely crazy! It heats up just fine on both AC and propane - no issues there at all. But the cooling is completely unpredictable. Sometimes it works perfectly, other times it just stops cooling for no apparent reason, even in the middle of the night when temperatures are stable.

I've been tracking temps with data loggers and can see it just randomly stops cooling even though there are no error codes flashing. The thermostat tests good at about 8k ohms at 85°F, which matches what the service manual says it should be. I've got fans helping with air circulation and exhaust ventilation, so I don't think it's an airflow problem.

Before I throw in the towel and replace this entire fridge, what should I be checking? Is this a cooling unit failure, or could it be something with the control board or sensors? I really need to figure out what's actually failing here because this intermittent cooling is making our trips miserable! …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

Norcold 1210 Not Cooling with No Error Codes: Troubleshooting Guide

Looked at my Norcold 1210 refrigerator in my Grand Design 303RLS this morning — it's running perfectly normal but everything inside stays warm with zero error codes. Everything seems to work - the control panel responds, lights come on, and it even fires up on propane - but there's absolutely no cooling happening. Temperature reading shows 43°F and climbing.

What's making me nervous is that there are no error codes or alarms at all. I've checked the fuse and it's good, the little black box's red light is not on, and the fans aren't running. Usually when something breaks, you get some kind of warning, right? I'm worried I might be missing something obvious or that continuing to run it could cause more damage. Is this pointing to a specific type of failure, and am I safe to keep troubleshooting or should I stop using it immediately? …more
