Some good info, some, not sure where all the fervor comes from...
OP, google has a plethora of online calculators to figure this out. It’s amazing, anyone can be a first year electrical engineering student with the click of a few buttons.
But the short story is 100’, assuming about 20amps (running ac + fridge) = 10ga min.
And that’s at the limit of acceptable voltage drop for that scenario.
Of course someone could have wired the plug wrong or insufficiently. I spoke that’s worth mentioning, but not getting snide over.
