My father in-laws wife plugged a brand new air conditioning window unit I with a small extension cord and she said it ran for just a moment and then cut off. And it has not turned on again. Does anyone know what the problem is and can I fix whatever is wrong with it. It's brand new and I sure could use the help. Thanks

    what's the rating on the extension cord? Does the air conditioner's own cord have a lump on it with a couple of buttons? Commented Dec 31, 2017 at 2:28

Sometimes there is a reset button for the circuit near where the power cord comes out of the air conditioner. Usually a little black or red nub. Is the outlet still hot? It's possible she tripped the circuit breaker for that outlet.
