PCB Temp Error
E302
Control module too hot. Temperature sensor on the control module detects temperature higher than limit value. Control turns off heating elements and fan defaults to high speed. When cavity temperature lowers to 212°F/100°C, heating will resume and error will be cleared. (If self- clean was running, it will be disabled until a control reset is performed.)
