Plug Cord
Who do I do if my window unit air conditioner is causing the electrical plug and extension cord to overheat?
We have a large, vertical window-type air conditioner which keeps shorting out because the electrical plug prong is heating up and causing the head of the plug to be VERY hot and is making the extension cord overheat. Help!
I forgot to mention that my air conditioner's plug was overheating BEFORE I connected the plug to the extension cord. So, it seems something is wrong with the prongs/plug itself since one prong is burning a tiny, tiny bit or else the conditioner itself is pulling a bunch of juice for some reason.
Be thankful it is shutting down. If it didn't and the extention cord continued to overheat you would set your house on fire. Like the others have said - never use an extention cord on an appliance like an air conditioner. Most home extention cords are not made to carry that load.
Do as everyone is advising and get a plug installed close enough to the unit so you don't need an extention cord or move the unit to another window with a plug closer to it.
