Compressor motor is stalled on start up which trips breaker. Try changing out the start capacitor. Its supposed to change the AC phase to enable more starting torque on a stopped motor.

SOURCE: air conditioner will trip breaker when trying to cycle back on

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which  will eventually happen,if the compressor is tripping the brreaker as I suspect..

SOURCE: AC tripping breaker.

Check its wiring connection. Could be loose connection, corrosion.Or the breaker is already retiring. If the breaker is fairly rated to the aircon unit. Also insect could be the culprit.

SOURCE: dometic rv air conditioner over 100 deg. trips breaker.

The problem is that when u add up the electrical draw from all of these appliances running full bore, your draw exceeds your available amperage. Now you are doing the math and saying no...... Let me tell you why. It is rare to find a situation where a 100 amp service actually porovides 100 amps. You almost always have voltage dropo. And when you are adding extension cords to the mix the drop is even more. That said, When you are using the AC try to minimize the use of other appliances, especially the microwave which is a big draw too.

SOURCE: ac unit breaker trips off

First thing to do turn off the breaker in the electrical panel, then open up the AC outdoor unit, including the disconnect box, that should be mounted on the wall near the outdoor unit. Go thru and tighten all of the screws and wire nuts, look for burnt wires, while you are at it.
Turn on the breaker and try again, if it still trips, then we look deeper;
pull the control panel off the outdoor unit and look for the contactor, this is where the power coming into the outdoor unit hooks up to. There will be a set of contacts in the control, check it out and see if the points are badly burnt,
If all off the wire checking still has not helped, it will more than likely be a bad condensor fan motor or a compressor, the compressor is the big black thing in the bottom of the outdoor unit, making sure that all power is turned off, pull the plastic cover off of the side of the compressor, there will be 3 wires, make sure none of them are burnt and touching the metal, if they are, repair the wire and test.
Try this and if you need to know how to troubleshoot to see if it is the fan motor or the compressor, just contact me back.
If this has been helpful, please rate me.
Contact me if I can help you any more.
Sincerely,
Paul

Rv ac throws breaker. what all is wired to the breaker?


You can narrow it a bit. Turn the ac off and reset the breaker. If it trips then you have a short to ground likely BEFORE the machine. If it does not then it's internal. Only turn the fan on, no heat or cool. If breaker trips then it's in the blower. If not, turn on cooling. If it trips then, likely in compressor. Good luck!

Fuses


Make sure that the fuse is not blown by checking with an ohm meter. The circuit that the wheel pilot is on may also have a breaker. Make sure that the breaker is not tripped.

If the unit keeps tripping the breaker or blowing the fuses, then the motor is going bad, or at least needs some maintenance.

Inverter will not switch to invert when the ac power is turned off


I am assuming that no fault lights are showing on the remote panel, but if they are, then those indicate a problem, e.g. overtemp, or AC overload. If the former, allow the unit to cool down and/or provide more ventilation, and if the latter, reduce the AC load by turning things off. The inverter must be in "standby" mode (green inverter light slowly flashing) for the inverter function to come on automatically when the incoming AC is shut off. Also, the battery bank voltage must be between 10V and 15V for a 12V system, the inline battery fuse must not be blown, and the unit's pop-up breaker (on the right front of the box) must not be tripped.

Heat pump breaker tripped now no power to the unit at all


When AC unit trips the breaker it usually means one of four possiblities.

1) the AC unit is causing the breaker to trip, i.e. a shorted fan motor, compressor, or some other electrical component - in which case you will probably need to have a repairman look at it.

2) you've plugged the unit into a outlet that is connected to a breaker which is too small to handle the load the AC unit is putting on it.

3) a defective breaker (not likely but possible)

4) just a 'random' trip and if you reset the breaker it might work fine.

good luck!
