What makes the converter cycle all the time?
Fan coming on at converter will be directly related to load on the converter. If no lights etc on, the fan will probably shut off, but start turning on lights and it will come on. Normal operation, as it it just the cooling fan coming on under load to prolong the life of the converter.
Not working at all
you either have a bad run capacitor or low on coolant and you pressure switch isnt letting compressor come on
My ac is not getting cold at all and i need to
HelloOne quick way is if there is a sight glass on the liquid line or small copper line,you will see liquid freon in the glass.This means there is freon,but you need to put a set of pressure guages on the system to be accurate.usually if your low on freon the system will freeze up and then afterwhile do nothing.Suggest having a service person comeout to check the system for a proper amount of freon charge.
How to add freon to my 57915-331 duo therm camper
Normally that would be a closed/sealed system, not rechargeable, from the factory. Don't know what valve your seeing, unless someone has retrofitted it with valves for recharging prior to you purchasing it. I will say that quite often the reason for poor, or less cooling, than when new, is often due to simply needing a good cleaning of evaporator and condenser coils and fins. Has that been done lately?
Water drips into the camper through the foam
Sounds like your drains for drip pan under the evaporator area are plugged. They are located at the base of the AC unit on roof. Look real close under AC unit near front, for a hole in base plate of AC on each side. Water ( condensation ) should be dripping out of those holes pretty steady when running.
You should have an inch or so clearance between base of AC and roof to try and get a bent piece of wire, or similar in to hole and try to clean it out. If that doesn't help you will have to remove plastic cover and remove all the screws that hold the front cover over the evaporator and remove the front metal cover. Look down at base of the coils and fins and you will see a drip pan that has small holes at each end for drainage. They will get plugged up with debris, thus poor, if any drainage. I use a long air nozzle and a small compressor to blow them and the tray out to clean it well. That will usually cure your problem. Please remember to shut all power to AC, off at breaker panel before removing the cover on roof to avoid electrical shock.
MY DOMETIC RUNS ALL DAY THEN IT BLOWS A BRAKER
Depending on how hot it is outside, there may not be a problem. It might just be running all day to try to keep up with the amount of heat that's outside. It'll blow a breaker most likely because it's drawing so many amps through the circuit breaker that it trips.

Most likely the starting capacitor on the compressor has failed the big way - by exploding. When that happened it effectively has became a short and that has blown the fuse.
Clearly a manufacturing defect - the capacitor has been defective from the start and it has failed almost immediately under normal use. Luckily this is exactly the fault covered by the warranty - have the unit inspected and fixed by the seller for free. Do not attempt to fix it yourself, that will completely void the warranty.
