I'm new to 123's...this is my first, and I have it about a month...it was very well cared for by the previous owner.

When is the electric fan supposed to come on? Mine doesn't seem to come on at all and my A/C is a wee bit warm...I suppose these are related?

This looks like an easy fix if the fan is bad (is there a way to tell if it's the fan and not something else?)...where can I buy one and about what can I expect to pay?

Thanks very much.
