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

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

MaxxAir Fan Shuts Off During Shower? Quick Sensor Fix Guide

Our MaxxAir fan keeps shutting off every time someone showers, so we're trying to decide between replacing the rain sensor or just living with it. The rain sense is turned off on the remote, but it still happens. After it closes, the remote won't control it anymore until I manually open the vent with the knob on the unit itself.

Is this a moisture sensor problem or rain sensor malfunction? What's the typical fix for this issue? …more

How to Add Coleman Mach Heat Strips to RV AC Unit - Heat-Ready Control Box Installation Guide

Tried running my RV's electric heating this winter but it's eating through power way faster than it should, so I'm looking at adding Coleman Mach heat strips. I have a SportTrek Touring 272VRK with two AC units (Coleman-Mach 13.5k BTU and 15k BTU, models 48203-069 and 48204-069) with Cool-Only Control Boxes (model 8330-752) and I'm considering adding Coleman Mach electric heat strips, but I'm worried about a few things.

First, I'm concerned about whether my current AC units are compatible with heat strips - specifically the Coleman Mach 37203-4551 Electric Heat Kit/Strip. I want to confirm this will work with my existing 8330-752 control boxes. Second, I'm worried about the electrical load - I keep reading about heat strips drawing a lot of power and I'm scared of overloading my system or tripping breakers.

Most importantly, I absolutely do NOT want to lose the ability to use my existing Suburban SF-30FQ 30,000 BTU propane furnace - it's my primary heat source and I need that independence. I currently have 9420a381 digital thermostats controlling these systems, and I want to ensure I can maintain my current setup.

Is there a way to safely add Coleman Mach heat strips using some kind of Heat-Ready Control Box without compromising my furnace operation? I just want some reassurance that this can be done properly without creating problems. …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

Ford F53 V10 Cam Sensor No Start: Step-by-Step Repair Guide 2024

Somewhere between last week's torrential downpour and this morning, my 2014 Bounder Classic 36H with the 2013 Ford F53 V10 chassis developed what appears to be a cam sensor failure preventing startup. The engine cranks over strong but absolutely will not start. I've been chasing this for weeks and I'm really hoping someone can point me in the right direction.

Here's what I know: Forscan is showing cam sensor faults while cranking, even after I replaced the cam sensor. I've got fuel pressure, the crank sensor is new, and there are no stored codes. The tachometer moves during cranking attempts, so I know I'm getting some signal. After crank attempts, there's a strong fuel smell. I've disconnected the battery ground for over 5 minutes to reset any hanging codes.

I'm starting to suspect this might be a wiring harness issue or possibly something with the timing chain. I have a tone generator on the way to check for potential wire breaks. The frustrating part is that everything seems like it should work, but it's like the PCM isn't getting the right timing information.

I really need guidance on the most likely culprits for cam sensor faults on these V10s. What should I be focusing on to get this thing running again? …more

Suburban SF-30 Furnace Replacement: Complete Unit vs Core Guide for RV Owners

Somewhere between our freezing mountain trip last month and now, my 2002 Born Free's SF-30 furnace died completely and I'm torn between replacing the core versus the whole unit. I believe it's a Suburban SF-30 model. I've been doing some research and see there are two options - I can buy a complete furnace replacement or just get a replacement core that supposedly slides into the existing SF-30 housing for about half the price.

I'm honestly not sure which route to go. The cost savings on the core is tempting, but I don't want to make the wrong choice and end up with more problems. As someone who's still learning about RV maintenance, would you recommend getting the complete unit or would the core replacement work just as well? Any guidance would be really appreciated! …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

RV Fuel Filter Replacement: How Often & Maintenance Guide

Every time we plan a big RV trip, something goes wrong - and now my 2005 Tradition 40W motorhome is running rough with fuel delivery issues just days before our two-week cross-country adventure. We're fairly light users - only putting about 1,200 miles on it annually since we mostly use it for shorter trips and occasional longer vacations. The coach has two fuel filters that I can see: a Luber Finer LFF1003 and an LF5488. I'm not entirely sure when they were last changed, possibly not for quite some time.

I've been researching maintenance schedules and seeing conflicting information about fuel filter replacement intervals. Some sources suggest every 10,000 miles, others recommend annual replacement regardless of mileage. Given our low annual mileage, changing them every year seems excessive and potentially wasteful. Our local RV service shop does annual maintenance including oil changes and general inspections, but they haven't specifically flagged the fuel filters as needing replacement.

What would be the appropriate replacement interval for fuel filters on a low-mileage RV like ours? Should I be concerned about contamination or other issues even with light use? I want to maintain the engine properly without over-maintaining components that don't need frequent attention. …more

How to Cool Hot RV Window Frames: 7 Proven Heat Reduction Solutions

Three months into owning my first RV and I'm completely lost on why these black aluminum window frames are hitting 129°F in just 90° weather. I'm pretty sure I could get a nice sear on a steak if I tried.

I'm looking for the most effective ways to tame these heat magnets before they turn my RV into a mobile sauna. I've heard about exterior reflective covers, interior solutions with Reflectix, and I'm wondering what actually works best. Should I be blocking the sun before it hits the frames, or can interior covers do the trick? And how the heck do you attach exterior covers without them flying off down the highway like aluminum kites?

Any battle-tested solutions from fellow victims of the great window frame heat conspiracy would be much appreciated! …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

Newmar Bay Star 3826 Black Tank Vent Pipe Routing: Complete RV Location Guide

This dangerous sewer smell is seeping into my Newmar Bay Star 3826 where my kids are sleeping—could the black tank vent pipe routing be putting my family at risk?
