First diagnostic step
Check if the ESEC User Interface Board is powered on (are the surface element displays showing something). If not, check 120VAC going into the ESEC power supply board (connector P1) and low voltage supply from power supply board (connector P2) to ESEC UIB (connector P8). Then check connections between P2 on oven controller and P9 on ESEC UIB for continuity.
