Does your A/C unit have a manual? and can you specify what goes off? does the flashing temperature ever go off? Also do you have any cooling?

You can but the unit will have not control over temperature, and you can cause the unit to freeze up or slug the compressor w/ liquid refrigerant causing premature compressor failure. I would recommend replacing the thermostat if it is not holding proper temperature, but if dead set on bypassing it use a volt/ohm meter after unplugging it to find the normally open contacts and wire those wires together taking into consideration that the fan must run constantly with the compressor.

When you say dedicated circuit, you should have an electrical outlet that was installed just for your air conditioner. This outlet must have it's own circuit breaker that has higher ampere ratings. This ampere rating must correspond to your air condition horse power (HP) e.g. .75 hp, 1 hp, 1.5 hp, 2 hp. You should consult a qualified electrician for your safety.

Hi, This being 18,000 BTU is a 240 volt unit. The electronic in it work at 120 volts. I believe you have only 1/2 the electrical current going to it. Thus the Hum. CHECK YOUR FUSES OR CIRCUIT BREAKER!
A 240 volt circuit breaker has two sides or switches with a bridge between them. One of them may be tripped. Shut off the breaker wait a few seconds then turn it on so that the it engages all the way. It if clicks or pushes your fingers back and prevents you from engaging it, there is a problem likely with the compressor/fan or it's wiring, and it is drawing too much current and requires repair or replacement.

Hope this helps,
Best, Mark

There has to be a shorted wire in the Air Conditioner then....the GFI is suposed to do that if it senses a short anywhere in the circuit and if it is happening when the air is plugged in then it must be in there....

Normally this is a sign of a bad compressor or a bad start capacitor. The capacitor you could do yourself if its the compressor buy a new unit. sorry

what this means is an indication of gas linkage from the grill connected to the compressor which is very harmful to health .

what you will have to do from here is to put off the air condition from the electrical power supply to stop the pressure of gas from the compressor to avoid gas explosion from the grill (pipe) ,
then get your self the pear pipe (aluminum or metal)depending on the use material to fix up the linkage together with the hydrogen powder and (unit gas ) to fix up the problem .

please note this if you can not carry out this assignment your self then you will have to contact a technician around you to give you an helping hard in shop time because the linkage of the gas is degerous to health you might not passive it but it circulating in the room.
hope this help?.

thank you and thanks for using fixya.
