Pid control, valve & board have all been replaced still no luck, maybe getting a backfeed? Any help thanks. P.s. unit is 30ton process chiller

    TCB Bypass

    Is the jumper on the tcb board in the right position or is logic inverted?

    More info. please. Pressures, temps, etc. Try isolating valve and watch your suction ,valve may be doing its job due to low charge or starving evap. from improper metering. Again a little more info please.
