Thanks

Are you talking about a roof AC or the dash AC? This thread has references to both.

Modern roof airs are not really serviceable. They don't come with service ports. Sorry to be the bearer of bad news.

They do, at least in the U.S., share a common "footprint," that is they install in the same size hole. That way you don't have to use an identical AC to replace the original.

After leaving off for awhile, it restarted OK and seemed to work normally except now it sounds like the fan blade is hitting something as there is a "tinkling" sound. Then it quit working again and compressor will not restart.

And to make matters worse the bath exhaust fan quit and the rear camera mirror won't turn on, just beeps when button pressed.

Any ideas? Dealer checking for a dealer near Destin, FL where we are headed. The front A/C isn't up to the task of cooling the entire RV in the 95+ temps. Wished they had put a rear A/C in them like my Tahoes.

Update: Just tried it this morning in the relative cool and it seems to work so I'm thinking it's a heat related problem. Fan noise is getting worse so I'm thinking it has loosened on the shaft and moving closer to grill.
Service said that the inverter current draw when added to the A/C was what pushed it over the max. Next time will turn off the inverter. I think the grandkids would rather be cool than watch TV.

My salesman called yesterday and said others have experienced this problem and is sending new DIP switch settings that will lower the inverter current draw which he said would help but would take longer to charge the house batteries. Will post as soon as I'm satisfied.

I'm confused - are you running off the generator?

Strictly speaking, if you've already got 110vAC coming from somewhere (shore power or generator) the inverter shouldn't be drawing anything. The charger should be drawing, and the televisions will be running off the shore power or generator, not the inverter.

When hooking up shore power, or starting the generator, my usual sequence is this:
1 - Turn off all AC appliances that might have been drawing from the inverter.
2 - Turn the inverter/charger to "Off." This is especially important if I'm starting the generator, so that I have maximum available amperage for cranking the generator.
3 - Start the generator or hook up shore power.
4 - Start the air conditioner. Air conditioners have almost double the current draw when they first start up as they do when running, so it's best to start it when nothing else is drawing power.
5 - Once the amperage draw has dropped after starting the AC (usually less than a minute), then I start the water heater and other electric appliances that need to be running.
6 - Then I turn the inverter/charger to "charge only."

Never had a problem with load-shedding since I worked up this routine.

Only when running A/C when underway. Or using microwave.
