Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.
The voltage for the air compressor is needs to come from a double (two) pole breaker. The size of the breaker needs to be 250% of the full load amps of the compressor. The wire size to the compressor has to be 125% of the full load amps of the compressor.
The compressor will stay running only because there is a leak in the air system somewhere and the compressor is trying to play catch up.It will burn out if left to run continuously ...
because the compressor must be running to circulate the refrigerant in the system
A/C compressor not running
low on refrigerant or the compressor isn't running..
Bypassing the a/c compressor will not effect fuel mileage. As long as you have the a/c turned of it has no effect anyway the only time it has effect is when the a/c is running.
sounds like you ac compressor is about to crap out.
If the clutch on the AC compressor has seized, the engine can in some situations stop running. The compressor could be bad but it is also possible that the clutch only is bad.
If the compressor is running, the blower is blowing, and there's no cold air, you need freon. If the whining is from under the hood, the compressor may be damaged. That's what happens when running without freon.
Compressor not running, blown fuse, low of freon.
No, the compressor only draws out the heat from air. The blower motor either blows warm air or cold air.
Your compressor has possibly stopped working. If you are lucky, the serviceman will only have to replace the freon to get it going again.
