Thanks for the help guys. Here is an update.

The system would not operate again today. The temperature is only about 60 degrees outside. I have discovered that, with the A/C/Heat switch in the OFF position and the fan switch in the ON position, that the fan still would not run. I believe this problem has nothing to do with any outside components.

I went to the attic and tapped on some of the components. One of them looks like a fan relay, and the fan started running. I am still not certain which component is flaky. And the schematic is not readable. I could fix this if I had a schematic.

Any idea of where I can get a schematic for an Amana 1990 air handler?

Thanks again for any help you can give me.
