Question about Dometic Rooftop RV Air Conditioner

1 Answer

Where can I find a shroud for my 2003 model 59516.331 duo-therm high efficiency Dometic roof mounted dometic RV air conditioner?

My shroud cracked today while I was removing it to learn why the fan makes so much noise. So I need a new shroud.

Try googeling Camping world ,Adventurerv ,or best rv and truck supplies ,these are all in the USA who deliver to Australia.I usually find that it is much cheaper to buy parts like this from the US even with the delivery charge.

Good Luck John

SOURCE: dometic duo-therm air conditioner freezing up

Make sure that you are not running the unit on low fan speed. In the warmer months of the year, this will often cause the unit to freeze up due to the lack of air flow through the evaporator. If you are running on high and it is still freezing, then you possibly have a freon leak in the system. The brisk airs are notorious for the capillary tubes in the upper unit rubbing together and developing a small leak. The problem is usually where the two small tubes enter the evaporator housing. Remove the cover and pull the two small lines apart, damage should be apparent if there is any. If not, you may have developed a leak elsewhere and need to have someone check out the system.

Hope this helps,

Jeff

SOURCE: My Duo-therm Brisk-Air by Dometic rv ac wont cool.(The fan runs )

Usually just listening closely will give you a rough idea where to look for problem. When you have the fan on and switch to cool, (with temperature turned down low obviously) do you hear any type of "moaning" sounds from AC unit, or see lights in RV dim slightly indicating that compressor is trying to engage? Is the breaker tripping when compressor tries to engage? Do you hear a "click" from AC unit when switched to cool? If none of that happens, then I'd start thinking thermostat, or compressor relay. Normally if it's a faulty capacitor, the compressor will try to engage but will make a "moaning sound" and usually trip the breaker due to excess current draw. Someone experience in electrical should be able to test relays etc, but whoever does work on it, should be aware that those capacitors, as well as hydro in general are very dangerous to work with. The ("zap",- Shock) that you can experience from a capacitor or hydro, can be fatal.

SOURCE: I have a Dometic Duo Therm rv Roof Air Conditioner

These are a closed system.(meaning that there is no fill valves for recharging) But a heating & cooling technician can solder them on and re-charge the system. Only problem there is to get an estimate up front, and compare it to buying a new roof unit which also comes with a new warranty, as well as keep in mind that the freon went somewhere, so there is an obvious leak that will need to be addressed as well. Most times it's wiser and cheaper in long run just to buy a new roof unit.
Are you sure that the compressor is kicking in? Did anyone remove cover on roof and check lines from compressor to see if any cooling is occurring?
These don't often leak, that's why I'm asking. Any idea how old the unit is?
Perhaps in fairly new, it's a warranty issue.

Can I recharge a Duo Therm 600315.001 RV Roof mounted air conditioner? It uses R22 refrigerant. If not, where can I find a replacement or can it be serviced somewhere?


I would suggest that you visit an ac specialist shop as all air conditioners( car, truck , house and yours all use the same principle of operation
because it is roof mounted in an RV may be a caravan repair shop that has an ac specialist in the workshop or a truck service shop that installs ac units in truck cabins would be a good place to start

Duo therm ac in my rv quit when the converter burned up does the ac need 12v to work?


there is a fuse located under the shroud on the roof AC on a circuit board that controls the thermostat to turn on the power to the Air Conditioner replace it it is marked F-1 or, on some F-2 etc.
the air conditioner works on both DC voltage for the thermostat and AC voltage for the compressor

Is an old unit worth fixing?


I recommend going with a new one. Both the coleman and the carrier are excellent and a whole lot more efficient that the 16 year old dometic.
