Re: current draw
If you look at the rating plates they should give you the info you need, usually.
But that Maytag will pull a fair bit when it goes into a defrost cycle I expect.
If there’s electronic involved though all bets are off as using a generator (as I know from bitter experience) can wreak havoc with them if it’s not a really, really good one and they cost megabucks I’m told.
If the appliances detect an out of range supply they will shut down, if they don’t blow something.
