    Unhappy Am I over my head?

    I am trying to use the blower on an old Milwaukee-Thermoflow Model 1103 to push air for a second hand central air system I put in, the furnace is oil fired forced hot air, the cooling exchanger is all installed in the output plenum and I have the thermostat wires run to a Lux heating and cooling controller, the thermostat runs the heat but won't run the cool, I did notice the transformer puts out almost 29VAC the contactor in the compressor needs 24Vac and the compressor works because I tested it with a 24VAC plug in transformer, so what am I doing wrong I know it will work ?

    Seems you are,
    If you did all of that but can not find the reason you are getting now power to the condensing unit contactor, I do not see anyone being able to help you from remote locations.

    I can only suggest that you get a tech out, but, you may find that most people will not work on homemade, or bodged together equipment as there is no actual system and there is liability for home built equipment.
