RE: Can AUTO mode damage A/C from frequent shutdowns?
Fan on auto means when the compressor reaches the set temp it will turn off. in auto the fan will turn off also. Hi or low it will run all the time. My trailer and my house are set this way. I can cool my trailer to 70 degrees. If your compressor is short cycling then you are low on Freon.

RE: Can AUTO mode damage A/C from frequent shutdowns?
Perhaps member Doug can enlighten us a bit more, but from what I know about my Coleman Mach 1, regardless of the fan mode, etc. once the compressor cycles to Off there is a 3 min time delay before the compressor can restart again, this to allow time for the high-side of the compressor to equalize (or bleed down) to the low-side, however can’t say whether this attribute is driven by the air conditioner or by the t-stat...
3 tons
the time delay starts when the uni has been TURNED OFF. it will not try to cycle it's self in just 3 min. if you turn it off or the power goes out it will not restart for ten min. not 3.

RE: Pulling more than 50 amps ?
Three? Each is maybe 16 max so even 4 would pull only 32 per side max.
Licensed electrician or handy man?
He is referring to total load of an RV with 3 A/C's. Not the load of 3 A/C's;)

RE: Pulling more than 50 amps ?
100 amps available....50 amps per leg x 2 legs...so answer is yes
100 amps available never came out of the mouth of a true electrician.
It would require a very precise balanced load. If one leg goes over 50 amps the breaker will trip. Period.

RE: Simple extension cord
If everything in the RV is up to snuff, there's no reason why a GFCI outlet shouldn't work fine, in the vast majority of cases at least. Most times when an RV trips a GFCI it's due to an actual problem somewhere: a neutral/ground short, or a leaky heating element in the fridge or water heater, or what have you.
(You need hundreds of feet of wiring for capacitive coupling to become sufficient to trip a GFCI, or maybe a dozen or so electronic devices with three prong plugs and RFI filters.)
As a master electrician Ii did side by side testing on my 2 trailers. It has also been verified by many others on different forums. Lots of times 2 GFI outlets in series do not play nice. Neither of my trailers would work on with 2 GFI's in series. Either turn off the RV gfi circuit or plug into a non gfi outlet and everything was fine.

RE: Simple extension cord
You need to purchase a 12 ga heavy duty extension cord. Also purchase a 15/30 dog bone. Amazon is your friend. You need to plug into a NON-GFI'ed circuit.
edited 9 pm
yes If you have a 50 amp rig. You need a 15/50 or a 30/50 + 15/30

RE: AC problem from hell: Now compressor is turning off.
As a 50 year Master electrician my advice to you is keep your hands off things you know nothing about. In your first post you stated " I replaced the motor, fan blower and compressor". "Replaced a blower motor that wasn't the right one but made do". Scrape that junk off the roof and have someone else install a new one. A/C service work is not a DIY project. As stated above, RV A/C's are not serviceable like a home unit is.

RE: Adding second AC myself
Yes, Coleman is quieter than a Domedic. THe eastest thing to do since you are not experienced is to install a unit with the controls on the face of the unit. No t-stat wires and t-stat to install. Also a non ducted unit as you are just trying to do the bed room. Again less work. Just remove the vent and place the unit over the hole. Grab a six pack and watch lots of you tube to see how it is done. You will have to get very creative as to how to get the unit one the roof. Fork lift, tractor with front bucket, 3 people with lots of rope and ladders. Near by tree and a block and tackle. Think outside the box.

RE: AC went out after getting unplugged?
A/C's have a ten min time delay before they will restart. every time you interrupt the power it must reset and start the clock over.

Non working sensors are something you just must except from your RV. You will learn this over time.

RE: electrical problems
Having electrical issues after loaning out trailer for a week. AC doesn't work, refridgerater works only on gas, sparks blowing out of converter. Opened converter because I could see debris behind the fan. Both capaciters were split open with the contents laying all over. While checking things out I got a scare when I was checking the neutral bar. I'm no electrician but I don't believe the white wire going to the neutral bar should read 120v. Red wire going to breaker is 120v. Black wire going to next breaker is 120v. Ground wire to grounding bar is fine. If I just plug in with 120v cable its fine. It's when I plug in with the 220v 30 amp cable that things get ugly. How can the neutral wire get hot when plugged in with 220v?
call an electrician and do NOT plug in until you do. Sparks means failure of the system.

RE: electrical problems
So you have a 50 amp RV and you are using a 50/30 RV adapter and plugging into a NEMA 10-30 outlet? Yea.... DON'T DO THAT.
Many things have now been burned up starting with the converter. The supply is 240v and the adapter is 120v.
Using a dog bone to plug 50 into 30 is done all the time.No problem.

RE: Converter/charger ?
Don't you have factory unit in the camper already?
Would I need new converter, I would consider inverter/charger instead.
Probably more educated advise in Tech Section.
OP is looking for the one he has not a new one.
