CPE suggested a hard start capacitor but I'm interested to see if there are any other options out there. I am in agreement with Wayne. Since the A/C and galley outlet should not be sharing the same circuit - meaning there should be NO current load on the GFCI from the A/C, I would do the following as a first step: Check for a bond between the neutral and ground with the RV unplugged from any power source. There should NOT be any bond between the two. If there is, find the problem and correct it. If the no-bonding checks out as being correct, then replace the GFCI outlet with a new 20 amp rated unit .
