Freon, thank you for your reply and willingness to help.
The wires from the thermostat enter the upper section of the inside unit through a hole on the left hand side facing the unit.
I removed the silver tape and silicon sealant that was sealing the access panel of the upper unit. (the upper section door and the metal venting leaving the top of the unit are covered in the silicon sealant, like a frosted caked)
The thermostat wires enter through a hole in the left side and are connected via wire caps to other wires.
The blue wire is wire capped to a RED wire that is a part of a another PAIR of wires, 1 yellow and 1 red.
That pair of wires enters the unit through the same hole the thermostat wires enter. That pair comes from the attic crawl space and it disappears up there someplace.
The Yellow wire from that PAIR is attached to another BLUE wire coming from inside the "accessory kit" mounted to the front of the unit. This is the same "accessory kit" that holds the 10 amp circuit breaker.
That blue wire (from the Yellow/Red pair) attaches to what looks like a 6 connection transformer. It has a part number of BE322640GEC with ratings of Pri 208/240v & Sec 24/40Va
The parts in that kit are that transformer, the Circuit Breaker, a Relay, a Solid State Timer, 2 items marked L140-60F and one more part jammed in behind the wires and the Circuit Breaker that I cannot identify.
The accessory kit housing has a label saying ADP Accessory kit Model no 0658664-04 if that helps.
The other 3 wires from the thermostat are connected as -
The White wire is capped to a thicker White wire that runs through a harness connector to that piece I cannot identify behind the CB.
The Red wire is capped to black wire that runs to a Safe-T-Switch on the front of the Bottom section of the Unit (which looks to contain a heater core, so I assume that is the heat pump section?)
The Green wire is capped to a Thicker Green Wire that goes to the Front Most connector on the Solid State Timer part number CT1845.
I should tell you that while waiting for a reply I went ahead and tried the thermostat troubleshooting instructions from other places. (its hot here and I was sweating impatience)
Put Yellow to Green and Fan ran.
Put Yellow to Red and Fan ran but not really cool, which the troubleshooting guides said should turn on AC.
Put Yellow, Blue, and Red together and the AC came out cold.
RC and RH are jumpered together with another Red wire
I did not mess with the White wire.
I should also note that the FAN setting on the Thermostat has NEVER kicked on the fan.
I did not realize this could be part of an actual problem when I discovered it months ago, I just assumed it was not hooked up to run that way).
Thanks again for your help Freon, any insight will be greatly appreciated.
