I was wondering if anyone knows where to purchase a schematic of the circuit board for a SM160 with a IQ4 controller? The schematic in the manual does not show any signal,voltage,etc, outputs. As a electronic technician with 30+ years of experience working on various circuit board I would like to be able to troubleshoot my circuit board to determine what once the temperature drops to around 40 degrees I can’t regulate the temperature or cook time on my IQ4 unit. Thanks.
