Hey all, total electrical newbie here!

I’ve got a Haier aircon that I run 24/7. Lately, especially in the early mornings, it stops working, flashes 'F19' six times, then tries to restart. It might do this a few times before it finally runs, but the issue keeps coming back.
 

An aircon tech checked it and said the voltage looked high (hit 251 when he tested). Then an electrician came by and said everything’s fine from his perspective. Problem is still here, though!

I’m okay with buying a new unit if I have to (this one's only a year old), but I’d rather fix this and save some cash. Did some Googling and watched a few Hindi vids — could it be an over/under voltage issue? I'm guessing in the early AM when power use is low the grid’s pushing extra volts? Any ideas on how to sort this out?

Thanks!

I would say nothing wrong with your AC F19 just shows under or over voltage from the Grid.
