I wouldn't assume that it's low on Freon just because it isn't cooling, that may very well be the problem, but there are other issues that could be the cause. No need to replace it only to find out that a thermistor was bad or a "freeze sensor" had slipped out of the cooling coils. Run the troubleshooting logic chart before you spend the money, you may find another problem...

Good Luck.
I appreciate this info. I will get the Carrier manual and check it out. Or is there some other manual I need to locate?

Another reason for possibly replacing unit has to do with the deterioration of the plastic parts. The condensing coil/fan cover has UV/heat damage and it is starting to "oxide" and crumble.
