Question about Dometic Rooftop RV Air Conditioner

Keeps kicking breaker

I have a ac on my 31 foot park avenue trailer. It was wired with a 10 gauge wire from a braker box which supplied 30 ams of power from the mail plle. The wire I was told was not powerful enough to supply power so i had a electrician run a seperate 6 gauge wire alongside the 10 gauge. Both wires have a seperate 30 amp breaker. The 6 gauge supplies the travel trailer while the 10 gauge wire only supplies the AC unit. It is a 15000 BTU AC. The ac will run for a while fine then all the sudden it will begin to cut out, as if the fan runs at a slower speed. This continues until the breaker kicks. I then rather than running the wire through the invereter to the AC I directely ran it straight to the box . It is however not grounded in the camper. It does have a ground at the main box at the pole. Does this need to be grounded inside the inverter box inside the camper? Or is this acceptable to run it directely to the pole. What I do not understand is that when the AC kicks the breaker it is the one in the camper which is the main breaker. The only other thing that is on is the ref.

Your unit is pulling too much power which is popping the circuit breaker. Either the compressor motor or Fan motor has a problem and you need a pro here. Drawing excessive electrical current is not good and you can do even more damage to your unit by continuing to try and run it!

Hi,
The problem is not in the wiring, but in the fan motor or compressor...would need to get a meter on the unit to see exactly what the problem is, but it aint the wire...

Here is a tip about trouble shooting your air conditioner...

1998 buick park avenue keeps blowing the stop lamp fuse, cant figure out why.


Yes. Thus is a short. Check the switch wiring and bulbs. Does the car have a trailer hitch with trailer wiring. Those are a common source of shorts.

Where is the trailer light fuse


The answer to this question depends on several factors such as: Whether the towbar was a factory fitted unit fitted during
pre-delivery, a genuine brand unit or an aftermarket unit & who, where & when it was fitted...
The majority of towbars & the assosiated wiring out there are simply wired in to the rear tail light circuits such as:
  • Trailer stop lights wired to vehicle stop light circuit in eighther of the rear tail lights.
  • Trailer park lights wired to vehicle park light circuit same side as the stop lights, as above.
  • Trailer number plate lights wired to vehicle park light circuit same side, as above.
  • Trailer reverse lights (if fitted) wired to vehicle reverse light circuit same side, as above.
  • Trailer left hand indicator wired to vehicle left hand indicator light circuit
  • Trailer right hand indicator wired to vehicle right hand indicator light circuit.
This means that if fitted in this manner (as the majority are) the corrosponding vehicle light fuse will affect the trailer lights unless the is an inline fuse fitted to each single circuit (which cld be blown). This is very uncommon & wld be a costly way to do it...

In some more modern cars that came from the factory (not the dealership ie. pre-delivery) with the tow bar fitted as standard equipment it is possible that there cld be a sepparate little fuse box or section in the main fuse box (the position of the fuse box/es shld be in your owners manual usually Under the bonnet, under the dash or behind font foot kick panels, & if you dont have an owners manual for your vehicle they are usually available to buy an aftermarket version or these days on the internet & often downloadable for free or @ a small charge).

All the best & I hope this is of some help...

Duo therm mod. 57915 air conditioner seems to work good , runs for 4-5 minutes then kicks breaker , was kicking 30 amp breaker at camp ground , i've been working on connections to make sure its...


Unit may pull as much as 17-18amps when compressor starts up, but level out to 12-15 amps when up and running. Keeping in mind that is all relative to proper 120v incoming voltage, heavy enough wire to run the application etc. If your AC unit needs cleaning , it may draw an extra amp or 2 . With that said, when your at the park, first thing I'd question is their incoming voltage to RV, and try running fridge etc and anything else on propane if possible. The AC alone should not cause 30amp at source breaker to trip, before 15 0r 20 amp breaker in RV that is connected to AC trips. If it doesn't trip your breaker at home, and all is connected same at park, then I certainly would suspect bad breaker or voltage/wiring at park is the cause. P.S. I noticed you said you have 12 gauge wire (rated at 20 amps) connected to a 20amp breaker at panel, but RV is plugged in to a 15amp receptacle, I will assume with a 15 amp adapter from 30 amp plug. Do you see any hazard regarding 15 amp rating on receptacle? ( just a little advice.)

I purchased a new Goodman AC/Heat inside and out side units, am getting ready to run the wiring to the sub panel, Not sure what wire to use from the main braker box to the sub box have found different...


http://www.encorewire.com/docs/amp%20voltage.pdf is a diagram of what size wire and type you need for different amperage. As you can see the 10/3 recommendation is good for a maximum of 30 amps in copper and 25 in aluminum.

I haven't found the CKL36AR36 installation guide, so I don't don't know which circuit breaker size you need to install. But it should be listed in your installation guide that you got with your unit. Make sure that you have the correct disconnect within 6 feet of the unit to meet code.

Where does the trailer battery charging wire connect to on a 2000 silverado 2wd w/o trailer package hook in?


UNDER THE HOOD, REMOVE THE LID OFF THE POWER DISTRIBUTION BOX. THERE SHOULD BE TWO STUDS STICKING UP, PROBABLY TOWARD THE REAR. DISCONNECT THE NEG. BATTERY CABLE. YOU WILL NEED A 30 AMP AUTO RESET " STUD STYLE" BREAKER. WITH 2 HOLES FOR MOUNTING. MOUNT THE BREAKER ON THE FENDERWELL NEAR THE POWERBOX. USE 10 GAUGE BLACK WIRE. WITH WIRE TERMINALS. GO FROM THE POWERBOX, TO THE BREAKER & FROM THE OTHER SIDE OF THE BREAKER TO THE REAR OF THE TRUCK TO THE TRAILER RECEPTACLE. I WOULD PUT THE WIRE GOING TO THE REAR IN A PLASTIC WIRE LOOM PROTECTOR, AVAILABLE AT MOST PARTS HOUSES BEFORE INSTALLING UNDER TRUCK. FASTEN WIRE WITH NYLON WIRE TIES AWAY FROM ANY EXHAUST PIPES, CAT CONVERTERS, ANYTHING SHARP OR HOT. FASTEN SECURELY IN TRAILER RECEPTACLE, RECONNECT THE BATTERY.

Wiring issue on a 1965 Roadrunner Travel Trailer


Generic comments follow:

I'm not real clear on what you are asking ... I can almost guarantee you that you will not find a wiring diagram for your trailer.

Your travel trailer operates on 12 V DC. Your frig, the heater, all the lights, radio, all 12 volts. Your running lights should be getting power from the tow vehicle. While towing, the tow vehicle should be charging the battery. You may find some 110 volt lights inside, but probably not. To keep your battery charged, you have 110 Volt AC power coming in. Your frig may run on 110 V AC but it still needs 12 volts for control. Your Air Cond and Microwave and TV (if equipped) will al,so run on 110.

Regarding the three wires from the battery, there should be a battery charger close by your 12 Volt fuse panel. Even though the trailer is a "vehicle" dont depend on using the frame as a ground like you would in a car. So, that accounts for two of the three - a red or black and a white wire. There may be some dedicated line that the battery supplied to account for the third wire.

There should be a emergency breakaway switch on the front of the trailer. This is a switch with a pull pin. If the trailer breaks away, the pin is pulled out by the tow vehicle and the electric brakes should be automatiocally applied to stop the trailer. This switch should be powered, unfused, directly from the traailer battery and go directly to the electric brakes - presuming you have this feature.

Be aware, this trailer power supply was built and designed for a life style far different from that we enjoy today. If you have a 30 amp cord, as I suspect, 30 amps is enough to charge your battery, run your 12 volt items, run a TV and AC or TV and Micro or Micro and AC but not much else. As you are aware, you have two circuits built with #12 and they are probably protected with a 15 amp breaker though the #12 would be protected with 20 amp breaker in a house. The cord is only rated for 30 amps and it may be tired, unless you have replaced it.

I hope I have provided a little insight to your situation. If I can be of further assistance, please let me know.

Where is my 1991 holiday rambler travel trailer converter


I had a similar problem on my 1995 Holliday Rambler Aluminalite 29 foot travel trailer with the similar layout of your trailer. My converter was only putting out 12.28 Volts DC. I fount the converter under the front of the trailer. (facing the front of the trailer, just right of center about 8" back)
There was a pannel with screws on the underbelly. I could hear the humm of the transformer. I removed the cover and found the red wire from the converter to a stud nut was loose. Tightened the nut and now I have 13.29 Volts DC.

Regards.

Fridgeidaire clothes dryer


I will try this again i don't think i posted it properly.
On the power cord where it connectes to the dryer make sure the red and black wire goes to the outside screws (L1& L2) the white goes in the middle and the green goes to the dryer cabinet.
If you have the red or black going to the middle one it will trip the breaker.
