AC not turning ON when generator runs

[dpitchai]

Hi,

RV AC was getting turned ON when I set to cool till yesterday. While runnning the AC turned OFF by itself eventhough it did not reach anywhere close the temperature set on Thermostat.

Today, after having the generator ON for 15 minutes, the AC is not getting turned ON. Other appliances like microwave is getting power though. Any help is appreciated.

Thanks!

Even though the inverter switch appeared to be at ON position, pulling it off and then to ON fixed the problem.

The noise from AC is about 65 db. Is this expected? Or may be they have poor insulation that is letting the noise from the roof to the inside of the unit?

So many possibilities. Your fan motor could be dying which could theoretically be the cause of both. For example, my Dometic Penguin II bought and installed last year already has a failing motor. The fan shuts down when it hits a thermal threshold (they're thermally protected) on hot days and when it was REALLY hot, tripped the dedicated 30A breaker it was on.

Not sure about your setup but a noisy fan motor and an unexplained trip at your inverter may indicate a pending failure. Let us know if stays on, changes sound pitch, or fails again.
