Trying to set air conditioner

i operate my a/c's in summer at 72 to 74 degrees. in the winter at72 to76.

Try setting the thermostat at a normal heat setting. By raising the temperature too high the unit thinks that the heat pump won't be effective and go into strip heat mode.

Chances are you have a bad capacitor or a bad fan motor, maybe a bad thermostat or thermostat connection. Your best bet without knowing what your doing would be to replace the capacitor( it is the part attached to the fan, bottom door, two wires coming out of it, silver). Even this requires some electrical know how. Turn off the power before you touch anything electrical. If that doesn't work then you should definitely call someone. Also a capacitor may be hard for you to buy in person without an account.
Good luck Hope this helps

Bad fan motor I suspect The windings are bad causing the motor to over heat sending the motor into thermal overload. would suggest the replacement of motor. Good Luck on repairs

turn the unit off for 5-10 mins. turn thermostat to coldest setting then turn unit back on. see if the compressor kicks on in a minute . it may need to reset itself.

A loss of "freon" charge will cause a pressure sensor to shut the system down. Needs tested for amount of charge.

dose it have a thermostat if it dose that will turn it off

Air conditioners need a few mins to stabilize (the fluid in the lines) after they are shut off in the middle of operation. The comperssor will normally time out for several mins after it shuts off (or you shut it ofF) preventing it from coming back on within that time. So if you turn it off, and then right back on, you can expect warm air for several mins untill it times out.

scrap the unit for alumimun and copper and buy a forty lol

the fan motor bearings need lub....the shaft has a tiny access hole to put some oil into. because the fan shaft is slowing down, it is putting more strain on the voltage current, and eventually the internal breaker shuts down the ac........plus your condenser is not getting enough air accross it, compressor heats up, and it too will shut the unit down......older units have to be oiled every year, and eventually it too will fail, and a new blower motor assembly is needed or replace the ac unit.....blower motor units are around $130....now you install it or pay to have it done at around another $150 labor,,,,,try yourself, if it fails then call the tech........let me know [email protected]
