Customer Question

I have a portable AC but when I plug it in it trips the circuit breaker. I believe my house voltage is 110 but the AC is 115. How can I make it work? Do I need to rewrite for the 115

The voltage is nominal and the unit will work on any 120V outlet. Sounds like the unit has an internal problem

Did you even read the question?

Yes M'am/Sir, i read and understood the question. But "110" volt equipment is made to operate from 105 to 130 volts. Voltage is not the issue. If you have a multi-meter I would test the fan and the compressor to verify that they are not shorted to ground. Sounds like one of them is with the breaker tripping immediately like it is.

Welcome. My name is ***** ***** would be glad to assist.

The question has come back to our open board since the expert has left the conversation.

Are you still in need of any assistance on the situation?

Do you have a 2 lead voltage tester with a readout or know someone who does and can help in the situation?

Does the unit trip the breaker when you plug it in, or only when you turn the unit on?

Can you set the thermostat as high as it will go, and then only try the fan portion, not the cooling and see if it trips the breaker also?

Let me know and we can continue,
