Bottom of the machine is the solid state relay for the PID; Todd tells me this is unlikely to fail. The black box below the PID is the giemme; and the display is the PID as you said. I don't know how to test the giemme short of swapping in a known good one. I would do the PID first, and then the giemme. Also could pop the cover on the giemme and look at the two relay points in the clear blue housing. One set was pretty clearly burned on my old one. Best, bmc
