I was recently told that my ac compressor had been ruined because the plug that plugs into my generator had the hot and the common swithced. Could this cause damage to the compressor?

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.

I have a 2002 pt cruiser that is blowing the ac 10amp fuse repeatedly. I mean within minutes of changing it. Also the ac is only blowing hot air. Can someone please help.


An AC system blowing hot air is usually due to a low freon charge or a non operational AC compressor. If the fuse blows, disconnect the compressor electrical plug and turn on the AC. If the fuse doesn't blow, suspect a compressor problem. If the fuse continues to blow with the compressor disconnected, there is a direct short between the ON/OFF switch and the compressor which can take hours to diagnose

No electric output, how do I diagnose, capacitor, proper winding check etc.


Have you tried flashing your generator? Sometimes the magnets in the generator loose their polarity. Google and YouTube "flashing a generator"
HFLASHING the GEN

Sometimes the magnets lose their polarity. This worked on my brothers $1200 gen. Its worth a try. Good luck!
Check all wires/connections first, Then try this-
(Remove spark plug wire first!)
To flash the field on a small home use generator, get an ext. cord & cut off the female end of it & strip the wires & connect the wires to a 12 volt car or lawn tractor battery, & plug the male end of the cord, into the 120 A.C. side of the generator.

Make SURE that the black wire which is POS/HOT on an A.C. cord, gets connected to the RED/POS. side of the auto battery, & the white wire on A.C. cord gets connected to the BLK./NEG. side of the battery. If the ext. cord wires are not black & white, then the smaller prong of the plug is the POS./HOT

Plug the other end of the ext. cord into the generators 120 volt side (**remove spark plug wire**) & pull the starter cord 4-5 times, then remove the ext. cord, reconnect the spark plug wire, start the unit & plug something of 120 A.C. volts in to see if it works. Then let it run for about a half hour with 2 - 150 watt lights to help re-generate the unit.

WILL A TRACE 2012 INVERTER RUN A 15000 BTU RV AIR CONDITIONER


According to specs, they will take a 44 amp AC power surge. Obviously number and type of batteries as well as battery condition , etc, plugged in, not plugged in to outside hydro, or generator all come in to play here, but a 15,000 BTU roof AC will only draw, 15-17Amps AC when compressor kicking in, ( or less on some new models) and should level out at 12 -13 amp draw after. As well, this will depend on proper wiring to and from main panel as well as AC unit, and incoming voltage, AC unit condition ( cleaned and maintained properly) etc.

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?

1986 chevy S10 has no power (12v) at fuse box on the fuse for ac clutch. checked both sides of fuse to ground 00v. ac/heater fuse 12v both sides (fan) works fine


hello, check all fuses, and relays, make sure wires to ac is not broke or has been pinched, sometimes you can run hot wire from battery, to compressor, touch hot side of plug in on comp wire see if it will kick on, if so sounds like a short, if compressor dont kick on with hot wire run to it, tap the out side of comp clutch and see if it kicks on, these compressors will not kick on any way if they are low on freon, once freon is full it should work.

No power for AC compressor


try removing the plug off the low pressure switch on the accumalator plug a paper clip into the plug and turn ac on if it comes on then your low pressure switch is bad or your low on refigerant.

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.
