With the interdiction of the CAN computer controlled systems in vehicles LED's Have been been changed to work with this technology. This is how one test's them. CAN Bus LED bulbs are simple plug-and- play LED bulbs which are made specifically for CAN Bus-equipped vehicles. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly. To see if your vehicle operates with a CAN Bus system, simply remove the bulb you're looking to replace, start your vehicle, and if you have a "Bulb Out" message on your dash you have a CAN Bus system.

Bill, I sent you a PM with a little information on the add on for the slide out circuit and that extra manifold. Rich.

Many hydraulic shops can repair the cylinders. This is a manual for the system that should offer some help with the repair of the system and how they are wired and plumed. many of the parts used are available or adaptable to the older systems RVA leveling PDF file covers system operation, hydraulics and wiring. Hydraulic system parts offers some information on the 12 volt operated jack valve parts that should get you close to what was used to build the manifold system. There are other part outlets one can use. The third PDF File is for the ADD On For a slide Room. Rich.

Eddie, Looking at your pictures. I have had leaks develop where the rear cap and roof seam overlap on the roof. There is difference in the expansion and contraction coefficients between the fiberglass and the roof structure materials. A leak in the seam sealing compound - will develop over time and once water gets between the top edge and the outside wall can travel unseen until it appears on the floor. You leak looks like it is at the top , near the opening for the slide wall from what I can tell from the water stained area. Rich.

dekontz6234 I do not disagree with Carl, cmarq or Herman. When the Engine is running - oil pressure is higher then the coolant pressure and when the engine is hot and not running - The coolant pressure is higher then the oil pressure. From your information / there is no oil in the coolant - only coolant in the oil. One way cross barrier transfer from coolant to oil? Water pump issue? Engines are setup different for different applications - Water cooled air compressor? Good luck ! Rich.

dekontz6234 3 weeks later I started the engine and the low coolant light came on. I checked the oil and it was a milky grey color. From the time you parked the coach at the park, was the engine ever restarted? Like Carl asked, What was the ambient temperature swing from cool morning to the high point during the day; over the 21 days? Rich.

There is a possibility of a blown head gasket, cracked head. Engine running Rough or white smoke in the exhaust? What year is the Coach / Engine ? Rich.

Been looking Also Richard ! There is a higher then I would expect issue or failure rate. This is some information covering a high on / off cycle rate on the units, But no mention of seized compressor . Generally with what you have described, I would look for the location of the sensing tube for the manual thermostat. The end of the sensing tube should be hovering right over the filter. If it is close to the evaporator coil, or close to the supply air chute, it could be sensing the colder temperature, and shutting the compressor down prematurely. Also, if the room temperature is near 65°F, the thermostat may be shutting it down normally. The lowest point that thermostat will run is right around 65. Interesting.Let me know what you find.Eric BottsTechnical Assistance CoordinatorRV Products, a division of Airxcel, Inc. Eric should be a lot closer then we are though Rich

The Original Poster has not mentioned any information regarding a ducted system. Sounds like the RV has just a single Mach 8, 15000 BTU, with heat pump. This Air Excel unit is a newer Low profile design, with 2 fans and is supposed to have the same low temperature cooling on both high and low speeds. The design sounds like it has a reversing solenoid that allows the units to transition from cooling to heating. The only items I can think of that would cause the compressors to fail on a total of 4 units is excessive head pressure - freeze up of the evaporator / cause ,could be the freeze protection circuit(this style circuit has been around for years on AC systems),but are both the condenser and the evaporator coils protected with this type circuit or the transition Solenoid not being able to move the slide valve through a full travel / OR the high pressure switch / Freeze switch common relay coil is failing - or the contacts of the relay can not handle the compressor start current. The Fan motor and compressor motors both run through the relay contacts. The blower motor does not go through this relay. The drawing of the electrical wiring does not show some parts that IMHO should be in the circuit to protect the system from counter EMF pules or high current surges from the starting and run capacitors. Tried to find any information on the number of recalls on this size and design, with no luck. If the Original Poster has had this issue - there should be a number of other owners with the same issue Rich. I'm totally aware that I have listed items beyond 99 + percent of RV owners skill sets or knowledge base.

Kimberlytene, Welcome to the FMCA Forum ! You might find a machine shop that could make the rails and the support arms if needed. You will need some good measurements. The other option might be a RV salvage yard. This is a link to a service center in Canada that might have some information or have a set you could get off a used unit. Rich.

The answer depends on the state inspection requirements for one and the second depends on where the crack is located and its present length. Some cracks can be stopped by drilling a small hole at the end of a crack and then injecting some clear epoxy at that point - kind of like fixing a stone chip before it spider webs. That kind of repair is covered by some glass converges or a fee of 60 to 80 dollars in others. Think it would be worth checking with an RV glass repair center and asking why the glass (Sounds Like it has a Stress fracture) Rich.

Bubba T, Welcome to the FMCA Forum ! Question, When your Units fail, are you running them in AC mode during the day and in the Heat mode during the evening ? Like setting the temperature at 70 to 75 degrees - where the units would switch from cooling to heating ! When they tend to fail. Rich. Airexcel makes a number of brands of Roof AC / Heat pump units. Note! This link is supplied for use by an authorized service center. However ! it can prove helpful for owners that have AC / Heat Pump units installed on Horse Trailers to Class AD Motorhomes. The Video describes what information is need and where to find part numbers and readings needed to help expatiate service. https://www.airxcel.com/coleman-mach/technical-service-videos https://www.airxcel.com/coleman-mach/service-support/model-number-changes The PDF file on the in question in this post.

Jim, Welcome to the Forum ! Could you list / Do you know who's AC system was used on your coach ? Denso is a large supplier for RV dash AC systems. If you can get to the Engine area - The Compressor is visible in most cases. Rich.

They are pretty close ride wise. Wheelbase and airbag setup also has some affect on how they handle and ride. Proper ride height setup has a noticeable affect on how they handle and ride. Rich

Rick, Welcome to the FMCA Forum ! If the air bags deflated - you should have had an alarm going off. Quick check is to park the coach on level ground and block the tires - both rears / front of tires and back of the tires(only need to block one tire on each side) Release the parking breaks. Knowing the Year would give us some needed info. Assuming you have air brakes. with the coach parked engine OFF- pump the the air brakes until you hear the alarm, keep pumping the brakes and at about 45 lbs of air or a little lower the Yellow park Brake will pop out. This is a simple test one should do before hitting the road, each day you plan on traveling is a good habit to get into !! Rich.

When something fails on our coach and I have had a longer then expected replacement time. I carry a spare when on longer trips. Radiators and CAC's are a bit bigger though. Have had to have a friend run down items, owned a privet parts store and he would do the leg work, find items and ship them to me. Sadly he has passed away, so that little ace in my back pocket is no longer there . Should you have someone like him, you are very fortunate indeed ! Rich.

What Leveling system is used on your coach ? When the fluid level drops on hydraulic leveling systems - there is an alarm indicating a low fluid in the leveling system. Did the Mechanic check the leveling system fluid ? and is the sensor float adjusted properly ? The other item to check on is the VDU Module. They have had issues with the solder connections that can cause erratic pressure readings and air pressure alarm to go off. The mentioned module was used on the model year of your freight liner chassis. They can be repaired in many cases - it you know a good electronics tech. Replacing them can run well over $ 1000.00, plus the labor. Rich. There are no Air lines connected to the Transmission on any of the Drawings I have for the freightliner chassis. There is(are) some wiring circuits that cause an alarm to sound when the transmissions are in gear when the park / air brake is engaged, or in some cases where a slide is not in. The coach builders add safety alarm systems that are not part of the original chassis.

Check the loaded weight - all four corners is the best way. We travel with only 3/8 tank of potable water and empty gray an black tanks as much as possible . Rich.

Rick, Thanks for the feedback ! This file should help it covers your leveling system well. Rich. RVA_Auto_Leveling_System_autopr80405.pdf

Squire, Not knowing your skill sets - It could be a challenge, but here is a PDF file that should cover the parts. The flat rate repair for the oven door repair is .3 hrs. for a qualified service center. Rich. atwoodrange Parts Manual.pdf

Rick, Welcome to the FMCA Forum ! Regarding your question(s) about leveling sequence. One should dump the air ride before using the leveling jacks. The air supply gauges on the dash also supply air to the air ride system. The Leveling system uses a hydraulic pump to level the coach. Before you air up the system to travel - retract the leveling cylinders. The leveling system information is offered - in an information file from SMC in many cases ! This PDF might be close to what your system looks like and operate like. Hope this helps. Rich. smc_leveling_system_2001 to 2003-Beaver.pdf

Mike, Using surge protectors in series is OK, but that will not keep the same issue if the connection issue if the connections loosen up . That is why checking the all the electrical connections between the shore power riser an generator to the Transfer Switch and the connections in the main 120 volt power panel and in the sub panel are tight. When driving down the road, the constant vibrations and bumps will - over time cause loose connections. Rich. Good game between LSU and AU last week ! That kind of game keeps everyone on the edge of there seat !!!!!

Mark, Welcome to the FMCA Forum! Kind of sounds like a failed VDU Module. Do you have a list of the parts that where replaced? Do you have a way to forward a copy of the repair order? Rich. The VDU units are reparable - if the problem is the one that pops up the most?

Bud, Welcome to the FMCA Forum ! The Owners Manual covers most of Systems, do you have one? This is a link to get a PDF copy! https://media.thormotorcoach.com/media/6098/2012-astoria-owners-manual.pdf It is 142 pages and covers the operation and systems quite well. The last page list the Contact information for THOR. Page 15- in the owners manual lists all the contact phone numbers for the suppliers used to build the Coach. WATER HEATER SWITCH-There is no reference to water heaters - Just where the water heater switch is located depending where they where placed depending on the Model. The water heater start switch is located on the wall in the galley, bathroom, or monitor panel area. The light illuminates when the switch is turned on. The light goes off when the burner is on and the water is heating. If the light comes back on, the burner is not yet lit. It may take several tries to light the water heater burner. When the element is turned on the red light will glow. Be sure the tank is full of water before using. Rich.

Gary, Welcome to the FMCA Forum! I have found the fuses behind panel / behind the Toilet. Do you have your owners manual ? Monaco does a good job regarding information in the owners manuals. Depending on how they wired your coach, or the floor plan can affect the wiring layout . 12 volt panel should should have labels for each fuse. Often refereed to as the front and rear run boxes. From your post it sounds like you have 3 items without power. That would make it sound like there is a common power point and that one fuse has failed or there might be a loose 12 volt connection in the fuse box - The 3 items should all have their own ground. Rich.
