Hello all,
My 240's air conditioning works great...for a while. After I run it for 45 minutes or so, the airflow becomes greatly reduced and the air isn't as cold anymore. The fan is working properly. If I just turn it off for 15 minutes (but leave the fan running), and then turn it on I get another 45 minutes of cold air.
My guess is that it's freezing up condensation on the heat exchanger, but I have no direct proof of that.
Question: Is that it? What else might cause this problem? What can I do about it?
