Two Electric Ranges with the Same Issues
Electric coil elements with &quot;hot spots&quot; are failing and should be replaced with new ones, not a different range with old ones (possibly the same old ones, if they swapped parts from one to the other, as they are pretty interchangeable and your landlord reads as &quot;cheap&quot;.) When they fail all the way, the arc can blow a hole in the bottom of a pot...just not a fun thing to let happen, particularly for a part that's typically $10-$12 or so.
An &quot;unpredictable&quot; oven is vague as heck, but typically you need an oven thermometer to hit temperatures reliably on any oven you don't already know the mapping of &quot;dial to reality&quot; for, as they are rarely accurate. I've had an oven element blow once, which was quite the show, since it arced wonderfully without exceeding the amperage of the range breaker, so it just kept arcing. I was happy that I was in the the kitchen and heard, then saw, it so I could shut it down. It was not subtle.
The range outlet hanging from the wall (or the power supply in general) would not affect either of these, but does reinforce the &quot;cheap or outright slumlord&quot; impression you're giving of your landlord. Often the only real solution to that is finding a new place to rent, though sometimes you can get a tenants rights organization to help you in attempting to fight with them, but it's often a losing (or pyrrhic) battle.
