my airconditioner unit shut down, outside unit froze up, what is the problem?

Answer 1

The unit at our church does this. It is running out of freon (in our case). We can't put it down below 85.

Answer 2

Check the indoor blower. If you have no air movement, the system will frost over. Check the filter, make sure it is clear and air can get through. Replace if needed. If the indoor fan is not blowing, check the circuit breaker for the indoor unit. If you have power, check the blower door panel to make sure the safety lockout is not open. If it is closed, do you have a belt-drive blower, or direct drive? check to see if the belt is good. If no belt, or belt is OK, check the motor. Is it hot, is it humming? could be a bad capacitor. Turn off the power and follow the purple wires from the fan motor, they go to the capacitor. Examine the capacitor, is the top popped up? If it looks ok, spin the motor. Does it spin freely, or is there resistance? If there is resistance, does it have lubrication ports, or is it permanently lubricated? Lubrication will buy you a few days until you can get a replacement motor. If no lube ports, you'll need a replacement motor. You'll need the voltage, horsepower, make and model number if available, shaft diameter, rotation from the shaft end, and amperage. Pick up a new run capacitor when you order the motor.
