A/C won't cool unless I turn breaker off and turn back on, heat pump unit

I've searched and searched but have not come across this situation. Thermostat set at 77, ambient temp 81, air handler in the attic blowing warm air, compressor and fan outside on roof not running. Fuses good, breaker not tripped but when i turn off breaker and turn it back on everything comes on after a time delay of a few minutes and blows cold. Once the house cools down, unit cycles off, the next time it calls for cooling the only way to fire the compressor off again is to go out and turn off the breaker and turn it back on again. Keep in mind, the breaker never trips. I even replaced the breaker because it was bugging me! Has anyone come across this situation? Any help would be great!

Thanks,

Gary

Welcome to the forums.

I go out and turn off the breaker and turn it back on again
Is this the breaker on the compressor unit....... not the air handler ?

Two things that come to mind are the contactor or the defrost board.

A make and model of the compressor would be a big help too.

Sounds like the system is shutting down on a safety and you need to find out what is tripped instead of simply resetting the control board by cycling the power.

Welcome to the forums.

It may appear that you have the same exact problem but the repair could be different if the units are different.
Do you have a heat pump system ?

You either need to check the pressure switches in the compressor or have an HVAC tech do it.
The unit could be low on freon. It could have a condensor fan issue causing the unit to run hot.

Tboisvert... please start your own thread so we can help you with your problem. Similar problems usually have different causes and to avoid confusion we would prefer a separate thread. Thanks!
