Judging by your description it seems there are some discrepancies but it is really hard to grasp the system without seeing a drawing of the installation. Firstly, the return air in a ducted domestic system does not use outside air normally as it tends to add too much to the installation price and also adds significantly to the heat load. Return air is recirculated air which after blowing from the supply ducting then flows and finds it's way to the return air grille and consequently the suction side of the evaporator coil. A thermostat is usually located near the return air grille or reasonably close so it can have a chance of knowing what temperature is in the internal space. Lets face it, how can an air conditioner really provide stable temperatures throughout the home in many different rooms that have differing heat loads (one room could be facing the sun and another room may be in the shade). Also, what is this resistor you mentioned? It is a little hard understanding how the A/C system is fitted without seeing a schematic of your layout.

They cut a square 21 3/4by21 3/4 in the utility wall going into the dining/kitchen for the return air to recool the house.Then 3 feet up the wall is the termostat above it.I know the termostat is in the wrong area.I don't understand why would you want to recool the air from the inside where they have two resister on each side of the inside door leading into the dining rm/kitchen.This just doesn't sit well with me trying to figure this out.I would thing common would tell you to first to have return air come into this evaporater from the outside?Also move the thermostat from the wall where as the resister isn't blowing cold air around this area.I talked to the A/c tech up the street who put this unit in back in 1994 when the house was built.He said what I was talking about is a gas unit.HUH! I looked at him cross eye scatch my head,well you can guess the rest.Please Its killing me trying to find a correct answer or a direction that I can start to look at. Going Nuts In South Texas coast!
