hey all, first off....im coolerboy and its just grand to be here -*chuckle*-

so yar..i need a bit of input...
about a week ago this supra 822 shows up on my doorstep with a burnt interface board (its the microprocessor model), after giving the unit a thorrough checkup i started to repair the thing but to no avail....all my efforts were in vain....u see, i have decent headpressure as well as 26 psig suction, i changed the expansion valve orrifice as well as the two valveplates, gave it a compressor oil change and a new drier. vacumed it for aproxx 13 hours and gave it a fresh charge. my expansion valve is responsive and all my other components are working fine yet i have NO cooling whatsoever. 0 degrees temp difference.....as far as im concerned the unit should be cooling but here i sit. any ideas?

thnx for a great site.
