AC problems

[camperone]

Can anybody help me with this AC problem ? I turn the AC on and in seconds it cuts off the fan works fine .

[Crockett]

probably too much voltage drop...need an rv cord no more than 75 feet possibly?

Try changing your temp setting. Set it to a much lower temp and see if that makes a difference. Also ensure your A/C power is in the correct voltage range.

We tried lowering the temp and our elec cord is 30ft.

[Crockett]

and the gauge of the cord? what size wire?

you need 10 ga....make sure you have the 110 breaker to the water heater off if you have one..

[camperone]

The cord that came with camper and didn't say which AC it was it the bedroom AC

[Crockett]

you got 50 amp service? ok..so no extension cord. are you trying to run 2 acs at once? your good for maybe one ac, no water heater, on household receptacle.

[camperone]

Yes we have 50 amp and yes there is two AC units but it has run both units for two years on the same 50 amp service inside the garage . So would it make a difference ? Do you think there could be the AC unit ?

[Crockett]

has the ac been sitting for awhile? sounds like a locked rotor in the compressor. possible problems: rotor seized in compressor, bad connection between source and compressor, compressor just breaking down, start cap or ptcr.
