Arrived on site and inspected well steam table unit. found controllers for right two wells to be mounted upside down. made adjustments and turned unit on and monitored amp draw on two right wells and had good amp draw. opened element box on furthest right and inspected element and high limit. both are in good condition. did find infinite switch to be short cycling and not allowing unit to hit temp. opened second from right element box to inspect element and high limit. both in good condition. infinite control out of range. middle well on unit the element box had dropped in the front of unit. resembled and had no issue. will obtain replacement infinite controls for far right two wells and knob for right most well. 10/19/20 At location with follow up parts for far right 2 hot wells. I removed covers and replaced infinite switches and tested. I found the end heat well not heating and no amps and the heat well 2nd in from right heating well with good amps at 3.4. I put old switch back on
