I have a 5 year old Trane XL14i - 3 ton I think. Yesterday I noticed
it getting warm and the blower was running, but the compressor and fan
were off. The contactor was engaged and power was getting to the
unit.

I turned everything off for about 10 minutes and then back on. Its
been working fine for 24 hrs. and register temps are right where I
expect - 62F at 110F evap temp and 90F outside temp. I'm wondering if
this is a fluke or if I have a more serious problem. What can I
check?
