Question about Dometic Rooftop RV Air Conditioner

1 Answer

Rv electrical question

Our rv has been tripping breakers when plugged in to garage. My husband turned everything off at the main breaker box in the camper and plugged it in and it still tripped the breaker. We tried 3 different adapters one which was brand new and it still did not work. He brought in the extenstion cord in and put the wires that go to the main black power cord into the extension cord and it worked without tripping the breaker. Please let me know if anyone might have an idea what is going on?

By the main breaker in the camper, do you mean the main 24 or 12 volt breaker, or the incoming 120vac breaker? Is it tripping the breaker in the camper, or the house? If it is tripping the breaker inside, i would look for maybe water damage, rusty components, maybe have an electrician come look at it, not worth going out away from home, and that problem ruining your vacation! Does this unit have a generator set? Try disconnecting the generator too. Hope that helps!

I have a Dometic 640315 that was installed by rv manufacter on breaker 15 amps. When i try to used it the breaker goes off.


I believe it is supposed to have a 15. Remember, breakers are installed TO PROTECT THE WIRE, NOT THE EQUIPMENT. If a breaker is tripping you just don't put a bigger breaker. The wire must be the correct size for the breaker. Take it to the manufacture.

Oven works but after it has been cooking for a period it shuts the Electrical Safety Switch off. Restart & it just keeps happening.


Well it may be the breaker that the oven is connected to, overheating the switch and tripping it. Try replacing the breaker switch (main breaker box in the house rv) is the best thing, but you can place a small fan from say a old computer or laptop conected to a old cellphone charger, there both dc powered. Just make sure that when you fix it to the breaker switch you leave plenty of room for the switch to trip if it has to ' to avoid house fires'. I had to do this one year because the heater I plugged in was over loading my breaker and had to Jerry rig a old computer processor fan to keep it cool while heating that area of my house

Outlets not working all fuses are good


120-
VOLT
AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

SECTION 6 - ELECTRICAL SYSTEM JAYCO TOWABLE
6-2
120-
VOLT
CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be
caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned "off"
.
Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.

Electrolux EOB 6632 oven trips main house circuit breaker if used above 180c. Installation electrician has done whole house test, says everything normal, must just be a particularly sensitive ciecuit...


Hi, welcome to FixYa! my name is Shaun. I hope i can help you out with your question. Your main house breaker is tripping over 180C because of the amount of current your oven is drawing. Keep in mind that an oven is capable of pulling up to 1/4 the amount of amperage of your total house current capacity, up to 50 Amps. This is assuming you have a typical 200 Amp main breaker. Add this in with your heating/air-conditioning, up to 30A, if electric, your water heater, 25 A if electric, and whatever lights and appliances you have plugged in and turned on, you can imagine how quickly those amps add up when your oven is on. Your oven breaker won't trip because you're not exceeding 50A on that circuit, however if your total household load is exceeding 200A, your main will trip. Also, breakers lose efficiency over time. Sometimes they can drop current capacity by as much as 25%. So your best bet is to replace your house main and see if that fixes your problem. Hope this helps out. Have a good day!

I have a 15 amp single pole circuit breaker that


It could be either or at this point. First thing to do, is unplug all electric devices from the plugs on that circuit, and then attempt to reset the breaker. If it does not trip, one of the devices plugged into a receptacle on that circuit could have a short. If it doesn't trip, plug each device in one at a time to see it it trips the breaker to pin point what is causing the short. If the above has no effect, I recommend replacing the breaker. It is easy and inexpensive to do. Just make sure you main is shut off before doing any work on the panel. I hope this helps and good luck!

No electrical power


You must find the reason the main breaker is popping ...

I'd start by unplugging everything and remove all breakers. Turn the main on ... does it pop? If it pops here look between the breaker panel and the end of your cord. Turn the power off - reinstall the first breaker - turn power back on. What happens ... keep doing this until the main or individual breaker pops - investigate that circuit to find your short.

If you get all breakers back in with out popping anything ... start plugging stuff back in. Something is shorting somewhere.

Let me know what you find please.

thanks

Installing a Dayton G73


How many amps is your service? And what gauge wire did you use for the heater?
If your service is only 40amps that is your problem. You don't have enough amps for the heater and the rest of your house, you will have to upgrade your service.
