When I tried to run a cycle, it immediately kicked back with a heater error. Which got me thinking. What if the transformer isn't a pulse transformer, but a current sense transformer? The controller must have some way of knowing that the heater isn't working, and there definitely wasn't enough time for the temperature sensors to be sending back enough useful data before that error was thrown. I still haven't had time to trace the PCB, but it will be coming soon!
