As a general rule ,only if your ac was a window unit. aka a 120 volt unit . all other acs use 240 volt. a 120 leg and a 120 2nd leg to equal 240, so there is really no common. what kills acs with a generator is the lack of watts and starting torque. an ac (3 ton) and up needs a generator of 10000 watts minimum to handle starting trque. they also need a hard start kit to boost starting voltage.for god sake someone reply and tell me what a good job i am doing!!!!!!!as in grade the response to your question.

My split ac`s compressor got overheated and stops working after 15 min but fan was running


this is because the compressor is thermoing out meaning it is getting to hot and the windings on the compressor are opening causing the compressor to go off, it is a safety for the compressor so it does not get ruined. have an ac company or someone who knows what they are doing come take a loo at it, it sound like bad start components to the compressor, also have then check the freon levels as well.

Replacing a condenser fan in centralized A/C


On of the common problem with centralized A/C unit is a bad condenser fan. I have known people who called an ac technician to fix their ac because of a bad condenser fan and suggested replacing the whole unit! Costing them a lot of money when all it needed was a 50 dollars condenser fan! If the condenser fan do not run or it runs only when you give it a push, it'sbad. You will also notice that it is vey hot. When replacing a condenser fan you may want to replace the starting capacitor too. Replacing a condenser fan is not very hard, just make sure that the power to the ac unit is turned off at the breaker box. Confirm that the wires are not live by using a meter or an ac tester. The fan motor are held with brakets sometimes just screws. Most fan you can buy that has reversible rotation by just reversing the plug. Make sure it is blowing upwards. If not reverse the rotation. So if you notice that the unit is not putting out cold enough air and you went outside and noticed the compressor running but not the fan, turn off the AC right away and do not use it untill the fan is replaced. Running the unit with a defective fan can damage the compressor caused by overheating.

What size circuit breaker is on the generator that is tripping? You'll need a 20amp for AC alone, then consider other things that are drawing current when RV plugged in like , converter, fridge etc that may be drawing current at same time. Make sure fridge is on propane, as well as water heater if you have electric element option on water heater. AC may only draw 12-15 amps when running if good and clean and wired properly, but will draw 17-18 amps when compressor kicks in. Perhaps generator not designed for that surge?

I have a coleman model 8333A8664 a/c unit on a fleetwood camp trailer and was wondering what watt generator would be needed to run it properly?


Because it won't be powering just your AC, I would recommend 5000W. It's that big amp draw when compressor kicks in that will pull it way down, if not strong enough. Take for example the fact that a dedicated 20 amp breaker and cable are the norm for RV's to use for AC now. Double check also that the generator your purchasing will take a momentary surge draw of up to 20+ amps without tripping breaker on generator. I say 20+ because once RV is plugged in or wired to generator, it will be powering any other hydro operated appliances, lights, converter etc that the trailer has on board. I bought a cheapie rated at 4000W, and 3000 running watts, but it kicks out the breaker just trying to start my portable air compressor, rated at 15 amps.

Trailer AC works plugged into house plug but trips breaker on generator and a light plant why??


Poor grounding on the generator or connecting wires. Weak breaker on the generator. Locked rotor amps to high for generator circuit. Weak capacitor causing too high amps for generator.

The fan is coming on but the compressor is not.Even after the unit has been off all night (long enough to cool down or ice to melt) the compressor does not come on.


All window unit compressor have a thermal breaker mounted on it. It is to protect it from overload. On a hot summer compressor work harder to keep us cool. Sometimes this thermal breaker fails for good. Unplug the ac. Open it, on the compressor there is a bulging thing sometimes cover with rubber. Thats the thermal breaker. Check its continuity. If you don't have an ohmeter, just byspass the two terminal of the thermal breaker with wire. Plug it in, but be carefull, turn on your ac. The compressor should come on.

RV AC, how to wire fan (blower) motor to capacitor.


You almost have it Look closer at the run capacitor. It has Herm, this is for the compressor, Com or C and F or Fan.

1 of your power wires is the fan speed so connect them accordingly usually black is hi, blue med, & red is low. You are "feeding" voltage to the selector switch on 1 side and coming out to the fan motor speeds.

Next you have a "Common" wire on your fan motor (this means its Common to all the other connections inside the fan motor to me. It is usually white. Connect this to the other line of power usually the Com on the capacitor unless it connects to a strip on the selector switch. But 1 of these 2 places will be the other side of your Power when plugged in. Lastly the brown it is usually the fan capicator only wire and it will connect to the fan "F" terminal on the capicator this terminal will not have any other wires connected to it.

This should make you a happy camper. Please rate me accordingly and good luck.

Circuit Breaker and Dometic Rooftop RV Air


Its the watts you plug in too like ither 30 watts vs 50 watts. 30 watts will cause your wires to get hot in the unit. just pull down your breaker box and look at those white ground wires.

Window unit trips circuit breaker


If your Plug is getting hot there is a voltage drop where the heat is generated. On these wall outlet recepticals there are two different methods of connecting the wires. First they strip the end of the wire and plug it into the back of the receptical . The second method is to strip the wire and attach it to a screw terminal . This is the best method for any outlet with a motor running from it.

For an example draw a straight line and then draw a circle that comes in contact with the line. Look and see how much contact area you have where the circle touches the line.
