Your coil is bad on the contactor. Make sure there is 24 volts to the coil if there isn't the transformer is bad. Any 2 wire touching each other that will kill a transformer is a heart beat.

Check for a control fuse in the condenser section.

DO THIS WITH THE POWER OFF!
Follow the main power wires until they stop at a connection and there is the contactor.

AC compressor wiil not turn on

You will have to find the contactor which is located in the outside unit. And check the voltage at the contactor, 26 v as this is the thermostat calling for the compressor to come on. You can also push in the contactor and see if the fan and compressor start. There should be an outside fuse box close to your condensing unit. Good luck

My air conditioner is not running on the outside but in the inside. temperature states 85 inside

If you turn down the thermostat to the air conditioner and the unit outside does not come on, you could have a few different issues. The usual suspect is a start capcitor. When you adjust your thermostat you should hear a click from the outside unit. If you hear a click but nothing happens, check the power disconnect out there by the unit. I recently had to replace mine because it finally just wore out. It can also be the contactor, the fan itself or the actual compressor.

Air conditioner not geting cool

Hello, It sounds to me like your low on freon/refrigerant. You'll need to have someone test the pressures for you.

Air conditioner freezing

Check your filter in the furnace, Then check the coil to make sure it is clean. If neither of these two solutions fix your problem you may be low on refrigerant.

Outside unit not working

If the heating and cooling is working O.K. and maintaining the proper temperatures it is possible that your outside unit is in its off cycle. If the inside unit is running and the outside unit is not with an elevated temperature inside check the power supply to the outside unit. Most units have a disconnect located near them. Check the disconnect and make sure it is set to the on position. Listen for a hum noise at the outside unit which could indicate that the control power is being supplied to the contactor.

Fan not blowing

Even when the power is off at the unit outside the thermostat will supply power to the contactor of the outside unit. This may give a hum or buzz as you stated. If when the power is on to the outside unit the fan tries to start but only hums the motor may be bad. Does the compressor start and run?
