Cause/Notes
Switch signals lost by latch position switch.
If a locked or unlocked signal error occurs, all
heating elements will be disabled. Error may
be cleared only by a software reset. See Cavity
1 (upper) Small Load Schematic.
Temperature sensor on the control module
detects temperature changes that, over time,
are higher than limit value. Control turns off
heating elements and fan defaults to high
speed. When cavity temperature reaches
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.)
