Sorry that company is not responding. That is pretty sore customer relations. It could be due to the china virus issue that could be affecting their business. Hope they follow thru and get your question answered in a much more timely manner, though.
I would not question the ground fault error but my thinking is if there is a ground fault it would show up regardless of what I was running (A/C, microwave, electric heater, etc.). The fact that the A/C fan didn't trigger the error is another indication that it's something isolated to the A/C system (could be wrong).
I'm very understanding if the China virus is impacting a business but if I call and I'm told to use the online means of communication due to the virus I expect someone would at least acknowledge receiving the message and provide a timeframe for when to expect a detailed response. At this point, two weeks later nothing.
