Ok im looking at my A-Coil and I see a metal strip on top of it (holding it together) and Two screws..is this what I would take off to remove the coils themselves to clean them? Ive tried the bleach/water solution but the unit still freezes up. I want to verify that they are not the problem before I have my system recharged with freon. Also what is included in a "service call" do they check everything then tell you a price or do they look at what you think might be the problem? thanks a ton. Im learning more and more everyday from these awesome forums.

The blower motor on my furnace/AC burned out, and I had it replaced. He replaced the motor and the capacitor. Now it doesn't work right. On heat mode with the fan set to AUTO, the blower runs for only about a minute (see next paragraph). On heat with fan set to ON, the blower doesn't seem to come on at all. When it is set to cool, the blower doesn't seem to come on at all. Even before the blower burned out, it would only work for a short time (30 - 60 seconds) before turning off. It would do this several times during the cycle. It's been like this for years. I just kept the fan in the ON position all the time, and it worked OK. There are three wires coming from inside my furnace, yellow, red and blue. Originally, these were all connected to the blower motor. after the replacement, the blue is no longer connected to anything. The connections are now: yellow from furnace to yellow on motor, red on furnace to black on motor, two browns on motor to the capacitor. There is also another set of wires coming from the motor that are jumpered to each other: brown to orange, yellow to purple. My questions are: Should the blue wire from the furnace be connected to something? Could the wiring cause the fan not to work in ON position? Could the fan burning out cause something else to go bad and stop the motor while it's in the ON position? Thanks for any help you can give.
