Question

Home ac outside unit will not turn on and off. It just keep running?

Answer 1

May be the contactor stuck or contacts welded together.

Do not run it like that. It needs to be repaired.

Answer 2

You might want to try tripping the fuse for it, in the breaker box.

If that doesn't work, you should call a repair person.

Answer 3

Thermostat is likely broken, so it can't tell the temperature currectly. Either get it fixed or turn it on and off manually.

Answer 4

if the inside unit turns on and off like it is suppose to then the contactor on the outside unit is bad and needs replaced....you do not want to allow the outside unit to run without the inside unit  running as this will cause the a coil in the inside unit to freeze up....until you can get a service man there i would recommend you put the fan seting on the thermostat to the on position and if your home gets to cold turn the power off on the outside unit...if you do this at least you can keep your home cool until you get the oudoor unit fixed....

Answer 5

Is the inside unit (air handler) turning on and off? If so then you have a problem.

If it is hot out all day over 15 deg. than inside it is expected and ok. Your unit is designed to run 24-7. It is still best to get a yearly check to make sure it is running at peak efficiency. My first summer in my first home saw temps over 100 deg in Florida and I asked the same thing, but paid 60 bucs for a tech to tell me the same thing. I found getting cheap air filters during the summer to help air flow better, then switching back to high dollar carbon odor reducing filters during less demanding times.

Answer 6

Is it cooling? Is there air flow from inside vents? If the thermostat is set lower than the inside air temp, it will continue to run. Try setting at a higher temp. If it still runs you may need to cut it off at the disconnect near the outside unit of at the breaker panel. If the lines from the unit are frosted or covered with ice call a service man.
