Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

Are you talking about the incoming AC voltage? That should be up about 120 VAC and if it gets below 110 VAC OR you are using it on a house plug with any kind of adapter or extension cord it will usually do this. What is the incoming power source?

We have the trailer plugged into a extension plug to the house and yes it has a adapter that goes from the trailer plug witch is a 3 prong 30A 125v down to a regular extension plug
RV Mechanic: Randall, RVIA Certification replied 4 years ago

That is the problem. Not enough power can be transmitted to the A/C that way. This is a common problem we see here all the time. You need a dedicated 30 amp plug and an RV extension cord for this.
