Monaco Diplomat Rear Air Suspension Won't Dump Fully - Troubleshooting Guide

Last week my 2006 Monaco Diplomat's rear air bags started refusing to dump all the way down when I hit the air dump before leveling. The front dumps fine, but the back stays partially inflated.

I'm still pretty new to RV maintenance and not sure where to start troubleshooting this. Should I be hearing air escaping when I activate the dump? What are the most common causes when rear air bags won't dump completely? Any guidance on what to check would be really appreciated! …more

How to Find Reliable RV Repair Shops: Expert Tips & Red Flags to Watch Out For

About every summer my 2004 Adventurer runs like a dream until temps hit 85°F, then it breaks down constantly and no shop can figure out why. The main slide out has been acting up with the HWH hydraulic system, and I honestly don't know enough to fix it myself.

I'm worried about getting taken advantage of since I don't really know what questions to ask or what warning signs to watch out for. I've heard horror stories about people paying huge bills for shoddy work. What's the best way to research and find a reliable shop? Are there specific things I should ask them before I commit to having work done?

Any guidance would be really appreciated - I just want to make sure I'm being smart about this and not walking into a bad situation. …more

RV Slide Out Won't Retract: Motor Runs But Won't Move - Fix

Planning to use the same motor running trick that saved my old Winnebago's slide out, but this new rig's slide won't budge at all. It extended just fine this morning, but now when I try to bring it back in, the motor sounds like it's working but the slide isn't budging at all. I can hear it running but zero movement.

I'm trying to figure out if this is a hydraulic problem or if I've got a cable system that's gone haywire. Could it be something simple like low fluid, or am I looking at broken cables? Don't want to mess around with it too much without knowing what I'm dealing with first. …more

RV Slide Out Moving Slowly? Complete Lubrication & Repair Guide [2024]

I tried everything I could think of, but after all that heavy rain last week, my slide out went from smooth operation to moving like molasses. It sounds like it's really struggling and straining, making these awful grinding noises that have me worried I'm going to break something expensive.

I've been reading that lubrication might be the answer, but I honestly don't know where to start. Should I be looking at the motor mechanism? The tracks? I've heard about hydraulic fluid but I'm not sure if my system is hydraulic or electric. I really need someone to walk me through what needs lubrication and what else I should check before this thing stops working completely!

Could you help me troubleshoot? Details that might help: Can you tell me the specific model of my RV and the type of slide out system it uses? …more

How to Lift RV Slideout for Floor Repair - Safe Methods

Apparently my 2000 Allegro Bus slideout only starts sagging and needing floor repair when it hits 85 degrees outside — works perfectly fine otherwise. We discovered water damage under the slideout and need to replace some plywood subflooring, but there are screws I can only access if I lift the slide somehow.

I'm worried about damaging the slideout mechanism or worse, having it fall and hurt someone. The hydraulic system seems to work fine, but I've heard you shouldn't trust it alone for this kind of work. What's the safest method to lift and support a slideout while doing floor repairs underneath? I want to make sure I'm not making a dangerous mistake here. …more

RV Electric Leveling Jacks Won't Extend - Fix Clicking Issue

Wondering if I should drop $800 on new electric leveling jacks or if this annoying clicking issue can actually be fixed first? The jacks were working perfectly fine on our last camping trip about two weeks ago, but now when I try to extend them, I can hear a distinct clicking sound coming from the controller panel, yet none of the jacks actually move or extend. The clicking happens consistently when I press the extend button, so it seems like the system is trying to respond, but something is preventing the actual mechanical operation.

I'm wondering what the most common causes are for this specific symptom - where you get the clicking from the controller but no actual jack movement. I'd like to understand the logical troubleshooting sequence, starting with the easiest things to check first before I dive into more complex diagnostics. The RV has been sitting plugged into shore power, but I know these systems can have multiple potential failure points including electrical, hydraulic, or control issues.

What should I be checking first, and what's the typical progression for diagnosing electric leveling jack problems that manifest with clicking sounds but no extension? …more

HWH 625S Slide Out Not Working: Step-by-Step Control Box Bypass & Repair Guide

Wondering why my 2008 Winnebago Adventurer 38J's HWH 625S slide out won't budge after replacing the solenoid, cleaning connections, and checking fluid levels? The passenger slide won't extend or retract from the wall switch, but when I manually operate the solenoid valves, the slide moves perfectly in both directions.

I've already replaced the solenoid valves, so I know they're good. The problem seems to be that power isn't reaching the solenoids from the switch - everything routes through the control box first.

Can I safely bypass the HWH control box by connecting the switch wires directly to the solenoid wires? What should I check before attempting this bypass? …more

HWH RV Slide Hydraulic Hose Repair: Complete DIY Guide

Replaced my HWH slide's hydraulic hose last month and now it's spraying fluid everywhere again with our three-week cross-country trip starting Friday! My 2007 Monaco Dynasty with HWH hydraulic system decided to throw me a curveball when the bedroom slide hydraulic line (1/4" I.D.) decided to spring a leak. After some detective work (and a lovely puddle of ATF to mark the spot), I traced it back to where a 1" air line to the front caliper had been playing the world's slowest game of 'saw through the hydraulic hose' for who knows how many miles.

I temporarily patched with Gorilla Tape and 1/2" hose clamps, which got the slide almost closed but still creeping. I'm planning to fix this with a compression coupling since that seems like the most straightforward approach for a DIY repair. Two quick questions: Can anyone confirm the 1/4" I.D. hose size for HWH systems? And once I get this coupling installed, will I need to bleed the system, or does it sort itself out? I'm hoping this repair goes smoother than my attempts to explain to my spouse why we're currently camping with a slide that's permanently 'almost' closed! …more

RV Stabilizer Jack Handle Spinning & Won't Retract: Complete Repair Guide

Apparently my neighbor's manual stabilizer jack retracts like butter every single time, while mine is completely stuck extended with a handle that spins uselessly. It cranked down fine but now won't come back up. What causes this spinning handle issue and how do I fix it? Is this something I can repair myself or do I need professional help? …more

HWH Spacemaker Slide Motor Runs But Won't Extend: Complete RV Repair Guide

Every time we get heavy rain like those three days last week, my HWH Spacemaker hydraulic slide system motor runs but won't extend the slide out. The motor runs when I hit the extend button, but the slide absolutely will not move out. Everything else works perfectly - rear slide operates fine, leveling system works great, no blown fuses anywhere.

I've tested the extend solenoid and it's getting power, did an ohm test which showed 1.2 and open (which appears acceptable per the manual). I've already checked the converter box and solenoids and they look good. The safety locks are fully retracted so that shouldn't be the issue. I can hear the motor operating but there's zero movement on the slide itself.

I'm really hoping someone can point me in the right direction here. What are the most common causes when the motor runs but nothing happens? Should I be focusing on hydraulic leaks or is this still likely a solenoid problem even though it tested okay? …more

HWH Leveling Jacks Won't Retract: Motor and Solenoid Valve Troubleshooting Guide

Every time I walk over to my HWH leveling jacks they extend perfectly but won't retract, leaving me clueless whether it's the motor, solenoid valve, or something else. But when I try to retract them using Store mode, absolutely nothing happens. I can hear the motor trying to run, but the jacks just sit there extended.

I recently replaced the springs on these jacks and I'm wondering if I somehow messed up the hydraulic system in the process. The spring replacement was a pain and I had to disconnect some things to get to them. My main question is: should I be hearing the motor run when I press Store mode, just like when extending? And if the motor runs but jacks don't retract, what's the most likely culprit?

I'm really hoping this is something I can troubleshoot myself before having to call in expensive service. Any guidance on what to check first would be a lifesaver! …more

RV Slides Creeping Out Randomly - Hydraulic Troubleshooting

Called the dealer about my practically new Tiffin Allegro Bay 38AB that's eating through hydraulic fluid because both front slides keep extending randomly. Sometimes it happens while we're driving down the highway, other times after sitting in storage for hours or even days. The weird part? It can also go months without any problems at all. The factory has already inspected everything twice - tested cylinders for internal leakage, checked all hydraulic lines, and even replaced the entire pump and valve assembly with their latest upgraded unit. Still happening! I've crawled under there with a flashlight checking every fitting and connection - bone dry, no hydraulic fluid anywhere. I even killed all 12V power thinking maybe a phantom signal was triggering the solenoids, but nope. Here's what's really puzzling: sometimes just one slide extends, sometimes both. Once we were parked on a serious slope (driver's side maybe 5-6 inches higher) and that slide still crept out uphill against gravity! I'm wondering if weak house batteries could cause the solenoid valves to malfunction? I'm pretty handy with tools and want to tackle this myself since the factory keeps saying there's nothing wrong. …more

RV Air System Leak: Front Tank Losing Pressure Solutions

Somewhere my neighbor's Class A maintains perfect air pressure in both tanks while my front tank keeps bleeding down overnight — what am I missing? My front air tank keeps losing pressure, but only when the coach is up on the air bags. When I jack up the rear and take weight off the bags, no pressure loss at all. Same thing when I dump the bags completely - holds pressure fine. The rear tank seems totally unaffected.

What's really puzzling me is after I shut down, I can hear this weird gurgling or burping sound coming from the front secondary tank until the system loses pressure. But here's the strange part - even though it's the front tank losing pressure, the rear of the coach sags way faster than the front after shutdown. I've meticulously sprayed soapy water at least 3 times on every fitting, valve, and connection I can reach around both the front tanks and rear bags, but I can't spot any visible leaks anywhere. Could really use some guidance on what I might be missing here.

Thanks,
Jon …more

HWH Leveling System Pump Failure: Diagnosis and Repair Guide

Before I throw more money at this HWH leveling system, my neighbor swears it's the shuttle valve, the RV dealer wants to sell me a pump, and YouTube says something totally different. Here's what happened: my shuttle valve failed, so I replaced it following the manual. The system worked fine initially - all jacks cycled properly during testing and worked the first night out. But on the second night, the pump started sounding different and the jacks wouldn't extend at all.

A tech came out and found zero discharge pressure from the pump. Now I'm facing a $5k replacement, but I'm worried there might be underlying contamination issues. Could debris from the original shuttle valve failure have damaged the pump? I really don't want to install a new expensive pump only to have the same thing happen again.

Should I be concerned about system contamination, and what steps should I take before replacing the pump? I'm nervous about doing more damage if there's debris circulating through the hydraulic lines. …more

HWH Leveling System Won't Start - Pump Troubleshooting Guide

Looked outside at 11 PM and discovered my HWH leveling system pump just died on me — need to figure this out before we leave in the morning. I've got a '96 Allegro Bus with what I think is called the HWH 610 leveling system. We were out camping last weekend and I started the leveling process, but someone suggested I move forward a bit for better slide clearance. So I turned off the leveling system, moved the coach forward maybe 10 feet, then tried to level again. That's when everything went wrong - now it just keeps bleeding air constantly and the pump motor won't even try to start. I've tried pressing the individual leg buttons but nothing happens except more air loss. Back home I've been doing some basic testing (please be patient with my limited knowledge). The solenoids all seem to click when I press buttons, and I've checked every fuse I can find. I suspected the pump relay since I wasn't getting any output, so I replaced it, but same problem. I'm getting confused about the wiring - should the small terminals on the pump relay get voltage or ground signal? Right now I'm seeing ground on both small posts. I also replaced all three batteries just to eliminate that possibility. I'm really puzzled how this went from working perfectly to completely dead in just 20 seconds. Any ideas what I should check next? …more
