RV AC Freezing Up? Fix Ice on Coils in 5 Steps

Turned on my RV's AC as a total newbie and watched it run perfectly for an hour before becoming a frozen disaster that won't cool. I can literally see ice building up on the coils, and then it's game over until everything thaws out.

This has happened a few times now and I'm getting tired of sitting in a hot RV waiting for the thing to defrost. What actually causes AC units to freeze up like this? And more importantly, how do I stop it from happening again? I'm guessing it's something simple I'm missing, but I'd rather fix it right than keep dealing with this cycle. …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

Norcold RV Refrigerator Not Cooling Properly: Complete Temperature Troubleshooting Guide

Before the summer heat kicks in, my 20-year-old Norcold absorption refrigerator only stops cooling when it's above 85 degrees outside — works perfectly fine the rest of the time. I've been tracking its performance with a recording thermometer for 5 days.

Here's what I've observed:
- Cooldown takes about 4 hours
- Freezer varies between 0 and 5 degrees
- Every ~24 hours the unit shuts off to defrost, heating to about 20 degrees
- Time to warm from 5 to 20 degrees is around 1.5 hours

I changed the temperature setting from 7 to 5 on day 3, which seemed to affect the temperature. The refrigerator section is hovering between 30 and 35 degrees during this time.

Is this temperature pattern normal for an absorption fridge, or does this sound like something that needs to be fixed? I'd really appreciate some guidance from more experienced RVers about what these temperatures might indicate. …more

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

Coleman Mach AC Leaking Water Inside RV: Complete Troubleshooting Guide to Stop Drips

I'm planning my weekend getaway when I spotted water dripping from my Coleman Mach air conditioner model 49003A879 that definitely wasn't there yesterday. I'm in Myrtle Beach, with super humid conditions (90s with crazy humidity) and getting pea-sized water drops falling from the ceiling vents at maybe 2 drops per minute, which doesn't sound like much but it's making puddles on my floor.

I've been keeping the main ceiling vents mostly closed to push more air to the back of the coach. Climbed up on the roof expecting to find some fancy drain pump or tubing system, but honestly don't see much of anything obvious.

Is this just how these Coleman units work, or am I missing something? Really hoping this isn't a 'deal with it' situation, but wondering if my closed vents are screwing up the airflow or if there's actually a drainage problem I need to fix. …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

RV AC Humming But No Air Flow? Fix It Yourself (2024 Guide)

I tried everything I could think of, but probably a dumb question—why would my 2006 Sightseer 30B's AC hum after storage but blow zero air? big mistake lol. The thing is humming like crazy but zero air coming out of any vents. It's loud enough to wake the neighbors but doing absolutely nothing.

I'm guessing something got stuck or seized up while it was sitting? Anyone know what typically causes this after long storage periods? Really hoping it's something I can fix myself before calling a repair guy. …more

How to Clean Clogged Duo-Therm 630515 AC Drain Pan & Lines - Complete RV Maintenance Guide

About five YouTube tutorials later, my Duo-Therm 630515 drain pan is somehow backing up worse than when I started this whole mess. The condensate seems to be backing up and I can see water where it shouldn't be, but only a little bit is coming out the normal drain line.

I'm worried about making things worse by trying to fix it myself. Is there a safe way to clear these blockages without having to tear into the unit or damage any seals? I have access to compressed air and a shop vacuum if those would help.

Any guidance would be really appreciated - I don't want to create a bigger problem by doing this wrong! …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

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 House Refrigerator Storage: Should You Leave the Door Open?

According to the moisture buildup around my residential fridge door seals after just two weeks of storage, I'm clearly doing something wrong.

With my old propane fridge, I religiously propped that door open during storage like every RV manual commanded. But now that I've got this "house fridge" - do I treat it like a regular home refrigerator and keep it closed, or do I stick with my old RV habits and prop it open? I'm probably overthinking this, but the last thing I want is to open it up next season and get knocked over by some horrific smell that could wake the dead. What's the right move here for preventing mold and keeping things fresh during long-term storage? …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

Advent RV Air Conditioner Not Cooling? Complete KoolRV Adapter Fix Guide

Around 6 AM I walked out to my fifth wheel and spotted my Advent air conditioner running but barely pushing any cool air through the vents. I replaced my old Coleman AC with an Advent, mainly due to price, but I'm not getting good cooling during the heat of the day. I've found that opening the slide vents on the ceiling cover helps a bit.

I'm considering using a KoolRV adapter like I had with my previous Coleman, but no adapter currently exists for the Advent. I've noticed the cold air discharge opening is located in the corner instead of the center, which I think is causing air turbulence and restricting duct airflow.

My main concern is whether restricting the airflow too much could cause problems like freezing up or other damage to the AC system. I've also seen that installing these adapters involves removing some kind of dividing wall inside the unit, but I don't understand why that's necessary.

Could someone explain if there are risks to restricting airflow and why that dividing wall needs to be removed? I want to make sure I understand what I'm getting into before I try any modifications. Right now, it's starting to cool down here in the Everglades, but I still want to improve my cooling performance. Thanks for any guidance! …more

Ford Triton V10 RV AC Repair Cost: Is $1400 Fair for Evaporator Replacement?

Already standing in the RV service bay staring at a $1400 evaporator replacement quote for my 2002 Pace Arrow with Triton V10 with no clue if that's highway robbery or fair. Tech says evaporator, dryer, and expansion valve all need replacing. Quoted $1400 for parts and labor, says it's an 8-hour job because of dash removal.

Is this price reasonable for this type of repair? What should I expect to pay for parts vs labor on a dash-intensive AC job like this? …more

RV AC Not Cooling Properly? Complete Troubleshooting & Repair Guide

Standing here after replacing my RV's AC compressor yesterday but it's still barely blowing cold air — did I mess something up? My dual AC setup absolutely crushes it when it's blazing hot outside - we're talking 95+ degree days and it'll knock the temp down a solid 15 degrees no problem. But now that the weather's cooled off to like 70-75 degrees, the darn things can't even keep up with the outdoor temperature. Set the thermostat to 69, outside temp is 69, and I'm still sitting at 75+ inside the rig.

I actually tested it yesterday - turned off the AC completely, opened windows and ran exhaust fans, and got better cooling than with the AC running! Now I'm doing this weird combo of AC plus open windows just to stay comfortable. What gives? Why would my AC units lose their mojo when the weather gets easier on them? Is this some kind of airflow issue or what? …more
