Cause/Notes
"Hot" wire shorted to ground. Connection to
the probe changes from connected-to-
disconnected multiple times. Probe is disabled,
but oven continues to operate. Error will be
cleared and probe enabled after a control
reset. Standard probe assembly is part of the
control module; see Communication Schematic
Measured temperature of probe is higher than
allowable limit. Oven will stop heating until
probe is removed.
Measured temperature of probe is lower than
allowable limit. Oven will stop heating until
probe is removed.
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.)
