well, I took the AC controller unit apart as much as I could (being able to see the solder spots). Most of the insides looked really good. Using a magnifying glass, I found several suspect solder cracks and re-soldered those. Put all back together and no change, dang it.
When I turn on the AC, it will work fine for a bit and then the whole system just stops. Blower motor stops, AC clutch disengages. Then system comes back on, runs a bit, then stops.
Not know this system good, do you all think its the HVAC controller which is the issue? I assume it is as if the High Pressure switch was engaging to turn off the compress, that has noting to do with the blower, as it should never turn off until the button is pushed to turn it off, right?
If the consensus is I need a rebuilt controller, any suggestions for a place to purchase one?
