New air conditioner problem

are you on shore power or generator? sound like low voltage and the unit is cutting out on thermal
low voltage = high amps which creates high heat,the thermal kick off till it cools down.

Didn’t think 30amp would run 2 AC’s? I guess it wont, sure sounds like low voltage to me as well

OP stated he is only using 1

Yup, just saw that.. helps if I use my glasses when reading!:o

Who installed them? Was the Intellitec ECC used and were they wired the same as the old ones?
You said that you were using just one. Does the other AC act the same?
Does it fail on shore power or generator or both?

Both will run at the same time. They will not start at the same time. The "shed" feature of the Intellitec Climate Control handles this.

If both of your old ACs would run on the system, I would say that who ever installed the new units did not install correctly. Some how they must have not wired the intellitec climate control correctly. Or that you need a new climate control board.

On a 30 amp RV they often install an Energy Manager by Intelletec. the purpose of this device is to limit your current consumption to 30 amps. it does this by cutting off one A/C and optionally the water heater depending on what's cooking (Drawing amps) elsewhere. Look for the control center

You can override and switch to the "Other" a/C but you won't get both of 'em on 30 amps less you cheat like I do.. But that is a major re-wire.

Need more answers
1. 1997, EMS may be a factor. Do you have the Climate control wall tstat Intellitec system that Fleetwood installs?
2. Or do you just have a Front/Rear manual AC switch?
3. If the previous AC units worked correctly until they failed and then the problem came up with the new install, then the odds are the installer did something wrong. BUT, installing 2 new AC units would not involve messing with the Intellitec system/wiring if you have that.
4. Did you install the SAME brand roof AC units?
5. You state the AC fails. WHICH AC? Does the other one operate OK?
6. BOTH will operate on Genset. What happens when you run the Genset? Doug
