YOU COULD HAVE A BAD RUN CAPACITOR. UNFORTUNITALY THERE UNITE USE A DUAL PURPOSE CAPACITIOR. 40 UFD FOR THE COMPRESSOR AND 4 OR 5 UFD FOR THE FAN. SOMETIMES WHEN THE 4 OR 5 UFD CAPACITOR GOES BAD THE FAN CAN RUN BACKWARDS AND MORE SLOWLY. TRY SHUTTING THE UNIT DOWN AT THE DISCONNECT WAIT 5 MINUTES AND WHEN YOU RESTORE POWER USE A SCREWDRIVER TO GIVE THE FAN A PUSH IN THE CORRECT DIRECTION. IF IT DOES RUN IN THE CORRECT DIRECTION, TRY REPLACING THE CAPACITOR.

Re: MODEL # CARRIER 38XD124300
Sounds like you had a condenser fan replaced ok you just have verify if the fan is a reversible one there is like a plug type connector on top of fan all you have to do is swap the position of the plug ex. if black / white to white/black that changes the rotation. check against the diagram it should be for the CCW position.

No. This is strictly a gas package unit, not a heat pump. the condenser fan motor should NOT run when their is a call for heat from the thermostat. The condenser fan only runs with the compressor on a call for cooling. Hopefully the compressor is not running @ the same time, but if it is, it would make sense that the contactor for the compressor & condenser fan motor is stuck closed OR the low voltage cooling wires are shorted straight to a 24Volt control wire.
If the blower fan in the furnace won't turn off, there is a tripped/blown limit. It's a safety. As for your condenser fan it could be a run cap or motor.
Do yourself a favor and have a licensed HVAC contractor take a look. Find a NATE certified or ACCA member. You will find a much better more qualified contractor.
Sometimes a motor can start to run backwards... on an indoor fan it is usually because the air inside for some reason started the fan backwards while it was off and then when power is applied it continues to run backwards... once this happens the fan is ruined and it often will not atrt the right way even after the air problem is solved...
You will need to replace the motor and see if you can figure out why there was reversed air flow in your system...
Make sure the capacitor is connected to the start lead, not the run lead(s). Also some fans come with some wires you can switch to reverse the direction. If your motor has them there will be 4 and the label on the motor will tell you how to connect them. Let me know if you need more assistance or if this helps.
there is a run capacitor is probably bad. you can purchase a replacement one from slakey brothers. However the capacitor will still have a charge after the power and wires are removed. after turning off the breaker use a long bladed screw driver and ground the electrical leads to discharge the capacitor before removing. take it with you to the supply house along with the model and serial number of the condensing unit.
Hi, this is an odd voltage 380 volts. Is it a 3 phase unit? To get a 220 volt 50hz condenser fan motor, you will have to go through a refrigeration/air conditioning parts house and order this. 60hz you would have no problem finding one in stock. Carrier is a good unit, and have been around for many years. You shouldn't have any problems locating one. Sincerely, Shastalaker7 PS You will need to go through a wholesale parts house.
Turn the power to the indoor unit off. Remove the cover where the fan is. Feel the motor of the fan. If it is very hot the bearings have likely gone out. If the fan is cool to the touch I would call a service company because you likely have an electrical problem that will require some training to solve.
