there could be quite a few problems with it. either it has something to do with the high or low safety pressure switches. Or you have a low voltage issue-not getting enough low voltage power to the coil of the contactor. how long do you wait after you turn the unit on? there is a 5 to 10 minute delay in the control board to keep the compressor from short cycling. meaning to keep the compressor from turning off then on again right away. short cycling a compressor too much will ruin it. There also could be an issue with the delay board it self. Or its a heat pump it could be an issue with the defrost board or the defrost sensor. I have even seen it to have a short in the wires of the coil of the contactor. But when that happens it will burn out the transformer or the low voltage fuse of the transformer or on the control board.

have you got it figured out already? If not can you give me more info on what it does? Or if it ever comes on after you wait at least ten minutes. Can you hear the hum the coil of the contactor makes when it is calling for the cooling. you might even have a problem with the contacts of the contactor not getting the proper power thru it to turn or keep the unit on.

Like I said there could be quite a few different possible issues with it to not stay on.

Not sure if you ever figured it out. Or if someone figured it out for you. Shows no one answered you on here. So I thought I would ask you a question plus also say what I thought it was . When the unit and or the thermostat was replaced? Was the thermostat wire that is inbetween the unit and the blower ever replaced? A service tech should have checked if the tstat wires were touching or shorted together. If you go by color which you should never do. Red is usually 24 volts or power, green is fan, yellow is cooling, white is heat, orange is the reversing valve if its a heat pump, orange to O terminal if RV in cooling or orange to B terminal if RV in heat. O or B terminal depends on who the manufacturer of the unit is. Blue wire is usually the common. you should always check to see how it is wired at the board or relay in the unit. not everyone wires it by the colors. If your fans low voltage wires are touching the low voltage 24 volt power wires in the unit or if the wires are shorted or touching in the wire sleeve or at the thermostat. the blower motor will never shut off. Or if the blower motor is wired directly to line voltage it will never shut off and testing the low voltage wire wont matter.

Your question was from last summer. So I am assuming you had someone figure it out by now. If not then check my suggestions. Hope that helps you.

Your system sounds like its become clogged and the pressure switch is turning it off before it burns itself up! Call a repair man NOW! Leave it off.

This is a two piece unit with an outside compressor? If there is no power to the thermostats, check the power at the inside unit. There should be a fuse and a transformer there. Check the fuse and if you have a volt meter, check the voltage on the secondary side of the transformer.

First, Open the Blower Access panel door of your air handler and touch the motor to see if it is hot to the touch.
If it is hot to the touch, turn everything off of approximately 1 hour.
Then with the blower access panel door off, turn the FAN back on and listen for any sounds. If the motor does not start, try spinning the blower wheel with your hand.......be cautious, because the motor could start up while you turn the wheel. If this happens, chances are good you have either a bad capacitor or bad bearings. To test the bearings, turn off all the power. Grab the end of the shaft and start trying to move it from side-to-side in every direction. Do not move it up-and-down. Up-and-down will not hurt anything, but it will not tell you anything either. If there is any movement side-to-side, the bearings are bad and the motor will need to be replaced. If you do not feel side-to-side movement, then there is a good chance it's the capacitor.....take to A/C supply house....they will test and offer you a replacement if it is needed.
If the motor is cold and it doesn't try to spin and it doesn't try to run on it's own after you spin it, then the problem is in the control circuit. Try putting a jumper at R & G. If the motor then runs, you have a problem with either your thermostat or the wiring from your thermostat to your Air Handler. If after jumpering R & G the motor does not try to run, then you may have a failed blower relay or a failed board (if the relay is internal in the board). Let me know if you need additional help. :-)

Bad fan motor.

Replace the fuse on the control board inside the air handler unit. If there is no fuse,replace the low voltage transformer.

Is the indoor fan running? check the breakers and reset as needed. also check the tstat . you should find a disconnect next to the outdoor unit some have fuses and some just are a copper bar device . If it has fuses check them .. if not you may have fried the transformer or the capisitor has failed. You will need equipment to check it let me know if this helps Jon

Hi, sounds like the capacitor may be at fault, it is a silver oval or round device connected to the brown wires off your compressor, one sign of a bad capacitor is the top where the leads are will bulge out , normally the top is flat, check there first and be sure to cut power to unit first!! I may be a dual capacitor (two in one) make sure the replacement is the same values as is there now, example if it is a 55/7.5 mfd 370v then you need to go back with the same, the volt side can differ to 440v if there was origanally a 370v, but not the other way, don't put a 370v where it was 440v.
This should help!!

Turn off the power and then use the garden hose to clean out the dust and grass.

Hello, turn off power to the furnace and remove the thermostat, then take the R and W Wires and put a jumper wire between them, then turn power back on if this turms on the furnace then you have a bad thermostat if it does not it is a problem with the integrated control board or possibly a low voltqge wire is loose.
