The Coaster has corrugated roof to main section. Would you flatten the corrugations or fit thick sealer


Hello,

Normally, what you would put thicker sealer. You don't want to smash the ridges. Sometimes i will measure the exact height of the ridges and some RV places make spacer to fill that gap prior to mounting the unit. I am not a big fan of that, as i believe the less holes the better for leakage. I would just make sure unit is secure, and if you want to put some cut to size plastic spacers and the sealer on bottom of spacer of course and after unit is installed, then you would seal the top of spacer along edge of your rv where it meets spacer. Only other thing to tell you is make sure the unit is good and strong when mounted as far as the framing on inside, so it will not bounce around and cause seal to break and leak. Best to use the rubber type sealer that is flexible. I hope this helps. MIke

Need to know the BTU's of a coleman rv roof air.


The limiting factor is the power available to run the device. Typically, roof air units are around 12,000 BTU.

Unless your rig is wired with a 50 amp service, you will not be able to run more than you have at the present with your 30 amp service. I have found that a rig with a microwave, a roof AC and a TV frequently cannot run all three at the same time. If you do have 50 amp service, you can add the second roof air. Also, if you have a 30 amp service, you can upgrade to 50 but that is an expensive proposition with the cord itself costing around $200.00. You would also have to upgrade the distribution panel and probably have a pro properly split up the load between the two 120 Volt AC buss'.

I hope this response helps you with your deliberation and thanks for your question @ FixYa.com

You can purchase one from any RV dealer usually, and they may even have some used ones cheap in their spare parts dept. Make sure if it's used, that it's not to brittle from the sun, otherwise you'll be replacing again.

I have a duotherm 15000 rooftop rv air conditioner that leaks


On most rooftop air conditioners, you can see the inside (evaporator) coils by looking up through the air return- some models are easier than others, though. This was a Coleman Mach series, so I could just see the coils, but could not access them for a good cleaning, so a trip to the roof was in store.

Getting access to the evaporator coils is not very difficult, you do have to remove the plastic shroud, and then some sheet metal on the front-

Roof Top Air Conditioner- exploded view

This is an exploded view of a DuoTherm BriskAir, but standard Coleman units are pretty much the same. A tip- when removing the screws that hold the sheet metal cover on, pay attention to the screws- there will usually be a few that have a blunt end on them, these are meant to usually go in to the electrical compartments, or where there are wires or tubing. You do not want to find out you put a sharp pointed screw back where it was not used originally.

Once you have the sheet metal cover off, I use a stiff bristle brush to “comb” any large lint off of the fins. Once the “big stuff” is gone, I use a good degreaser- I use VoomRV, because it is PH neutral and a great degreaser, Coleman recommends “Formula 409′. I tend to shy away from most commercial A/C coil cleaners as they are often very harsh on aluminum- they clean the aluminum coils well, but I don’t want the cleaner running down the side of the RV (something you don’t have to worry about in home units).

I soak the coils well, then lay heavy towels over the air intake to catch any water (I put towels inside as well- just in case), then spray the coils off.

This is a good time to check the drain holes for the condensation- there will be holes in the bottom pan on either side of the tray the coils sit in. It’s easy to clean them out. It’s also a good idea to check the gasket-
Air Conditioner gasket measurementmake sure the bottom of the unit is at least 1/2′ above the roof -

It is also a very good idea to check and clean the outside, or condenser coils. Sometimes they will be very clogged- as in the case from Dudes RV Air Conditioner page, but sometimes they might still look clean. Even if they do look clean- clean them any way! In air conditioners that have not been cleaned for a couple of years- and the unit has been used- I will consistently measure a 2 amp drop in current – just from cleaning. You will be amazed at the dirt which will come out of a clean looking coil.

While you are up on the roof with the shroud off, it is also a good time to check the fan motor- some units have oil ports- if yours does, put a few drops of electric motor oil in each port. You can also check the condenser blade. Another unit I serviced ( a DuoTherm) had a fan blade that was starting to go- it was cracking around the shaft attachment, which made it just a little of balance- to the point where it would hit the sheet metal every now and then.

I’ve got to say- RV roof top air conditioners are about the most reliable component on an RV, but they do need regular maintenance. As with most things I talk about, given regular maintenance, they will give years of service. Often RV air conditioners are replaced simply to add new features and lower current draw, not because there is really anything wrong with them.

Hope helps.

You need to find where the drain is. The water should flow to a drain and not into the unit. Once you get the condensation draining properly you can use a good quality silicone to seat around the unit. You might check at a RV parts place and find a product they recommend for RV roofs. Hope this helps.

Coleman tsr rv air conditioner leaks into rv when running


It probably has a clogged condensate drain. Take off the cover on top the RV and check hoses or tubes leaving unit for debris or lint. Often this water is used to help cool the condenser so look for leaves pine needles etc in the pan. There may be a cover you can remove on the evaporator section that will allow you to clean the collection pan and hose or trough. Is it possible the RV is far enough out of level that the condensate can't "run uphill"? Always power off while working on this unit unless you are electric savvy. Good luck!

I have a Dometic rooftop air conditioner 8000 model. When on heat in cold climate I found the a/c unit did not heat our caravan sufficiently.


the reason for this is either the reverser valve or air restriction first clean the a/c by removeing the cover on the roof and the inside clean the cooling fins then remove the sheet metal or plastic cover over the intake fan & clean the shroud then clean the filters inside the van reassemble every thing then turn the unit on & from inside check the side were the wires are to feel for air by turning the unit on cool there should be a big diffrance between the intake from the out put use duct tape to seal off the sides also clean the duct work with air to remove blockage in the duct
