    Digital scroll discharge thermistor

    I have a 7.5 ton chiller, Copland DS , med application on a Lin Acc. Flooded with uv40 rcvr that I believe has been running over charged with 50 plus # 410. The DS can't is going off on 2 flash code DT alarm and locking out comp during idle times with little-no load. pulled out four pounds hoping to make issue go away but has locked out again customer says. My concern is that orbiting plate may have been damaged with high temps discharge. This is a split system air cooled remote cons. With pump down about. Brazen plate

    When those plates go, i see gray coloring in the sight glass, strange random top end noises. Not a fan of how those units cycle on a very low load call.

    How many times must one fix something before it is fixed?
