DBUD Air Conditioner Issue

Hello Friends! My husband and I were camping last week in our DBUD. We were in South Louisiana where it was very HOT!! We had been running our air on low all week while camping. I turned the air to high and switched the vents from all vents to just the main vent at the return and the fan stopped. We cut the air off and tried turning it back on after a few minutes and it wouldn’t come back on. We decided to leave it off for the remainder of the afternoon to give it a break. We turned it back on that night, and it came on and worked fine without issue. Do you think it just got overheated? We were told these air units are tough, and meant to be work horses. We were told it was unusual for them to quit working then start working again. Does anyone have any ideas why it just quit, and started working again? We’re going camping again before the summer is gone, and want to make sure we have air. If there is anything that needs to be replaced, we would like to take care of it before our next trip. Any ideas or suggestions would be so very greatly appreciated!!!! Thanks so much!!!!

What model and year is your RV?

In the new Dometic A/C's the fan will stop and restart whenever it changes speed. Is it possible that you turned it off as it was switching speeds and that confused it? Then leaving it off a while reset it.

ALSO: Most modern compressors ( AC and Fridges) have a time out timer that prevent it from restarting immediately after stopping to allow the the pressure head to deplete.

Did the campground lose power at the moment from everyone running ac units at the same time?

Possibly a safety time delay in the unit to prevent damage from being short cycled.
Try the same sequence at a time when you don't need it to test for a time delay.

My husband felt that it just may have overheated and shut itself off. Your suggestion sounds very similar. Thanks so much for sharing!!

Not any power loss that we were aware of. Good thought though! We had been having several power failures throughout the week but at a different park. Thanks so much for your help!!

Good idea! We will definitely try it again now that we’re home before we spend money replacing any parts. Thanks for your information!!!!
