Temperature sensor disconnected or has a
faulty connection. Cooling fan will operate at
high speed and heating will stop. After two
consecutive temperature readings are made
successfully, heating will resume and error will
be cleared. See Communication Schematic.
Temperature sensor shorted to ground.
Cooling fan will operate at high speed and
heating will stop. After two consecutive
temperature readings are made successfully,
heating will resume and error will be cleared.
See Communication Schematic
Latch operation not determined by control
module. Door latch does not lock after 1
minute and further attempts will stop. Error
will be cancelled and normal operation
resumed if a locked door is no longer required.
See Cavity 1 (upper) Small Load Schematic
Temperature in cavity is too high or latch
operation not as expected. Door latch does not
unlock after 1 minute and further attempts will
stop. If the latch is detected in open state for
more than 10 seconds, the error will clear and
normal operation will resume. See Cavity 1
(upper) Small Load Schematic
Temperature in unlocked cavity exceeds the
allowable temperature. Oven will stop heating
