ac problems

Hello everyone. We have a 1999 bounder with dual ac. We have camp twice, and we are having problems with over current issues. We are setting both units on autocool on the electonic climate control. But at times it puts the control on "shed" According to our manual ,this means " insufficient power available". We bought this a few months ago , and still trying to figure everything off. I think the conventer is new. Its is located in a storage bin.Its a intell power 9100 55 amps. If the converter gets to hot , well it cause this problem with the ac Thanks for any info

On our old 98 Discovery, we endured this problem until we converted the coach to a 50 amp service. Watch your amp meter, and determine how many amps your ACs draw when they are running. Also try running the ACs on High Cool instead of Auto. This will tend to keep the amp load a little more consistent. Your ACs and inverter should draw around 25 amps based on what our old Discovery drew. If you have your refrigerator and/or water heater on electric, you will most likely being drawing more than 30 amps. Hope thie helps some.

Hi shep1261,
Is your coach wired for 30 AMP (3 prong male plug) or 50 AMP (4 prong male plug)? Does this problem happen anytime day or night or during peak electric load times (beginning late afternoon)?

Running 2 AC units with a 30 AMP connection will require:
1. Excellent and consistent CG power
2. Hot water and refer are running on propane
3. No high Wattage appliances running.

If you have a 50 AMP shore connection:
1. CG power is most likely to blame.

All this assumes your coach components are performing correctly. The converter will not cause this problem if you are on a 50 AMP connection. On a 30 AMP connection the converter should not cause this problem if the A/C units are the only high Wattage appliances running.

Please post again if you continue to have problems.

If you only have 30 amps you don't have enough amps to run both AC's and anything else that might be drawing to much power. I can only run one AC when on 30 amps but can run everything with 50 amps. Good luck. Jim

your 30 amp bounder has an electricity management system that will try to make the most efficient use of energy possible.

The system will shed loads as it needs to to keep the current draw under 30 amps while trying to do what you are asking it to do.
It will switch between running the front a/c compressor and then the rear.
As the others said, trying to get more than just the 2 a/c's at once will result in load shedding, usually the rear a/c dropping off.

This is all normal for a 30 amp fleetwood, your systems are working exactly as they should.

Thanks to all for the helpful info. I do have a 30 amp service . The shedding problems happen both times during the nite. I will try running the fridge on gas. Also will try to run only one ac at a time. Thanks again.
