Question about Goodman CKL60AR60 Air Conditioner
I have a Carrier air conditioner that the blower only turns on when set to heat but not when set to cool. I took the panels off and the unit gets cold but the blower does not turn on. What could cause the blower to turn on with heater but not with air conditioner?
It sounds like a thermostat or sequensor problem in the air handler

If you are handy with electronics then turn the furnace off and jump the G and R terminals at the circuit board. restore the power and see if the fan comes on. If it does, then your thermostat or thermostat wires are bad.
If the unit still does not blow on high speed then the problem is either the fan itself or the circuit board. The fan is easy to check. simply move another motor speed wire to the same connection on the board (not the white wire). if it comes on now then your high speed portion of the motor is bad and the whole motor should be replaced. If this test does not work then I think we can make a safe guess that the circuit board is bad.

I have the same problem. Did you get yours fixed?
If so, what was the solution?

From your discription... I would think you have a problem in the thermostat. Does the fan run in cool if you put the fan in the ON position. Some older t-stats have a jumper between terminals that brings the fan on in cool. You will need to find out if there is low voltage power between the green t-stat wire and common in the air handler. If you have a Gas furnace the fan comes on by a temp control also there is a door switch. If the door is off the door switch will be open. and no fan.
