Cavity 1 / Cavity 2 temperature
sensor open
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.
Check all connections and wires to temperature
sensor.
Check resistance of temperature sensor: if sensor tests
OK, could be control module problem; if sensor fails,
replace sensor.
E104
E204
Cavity 1 / Cavity 2 temperature
sensor shorted
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
Check wires and connections for pinch or short circuit
to ground.
Check resistance of temperature sensor: if sensor tests
OK, could be control module problem; if sensor fails,
replace sensor.
E106
E206
Cavity 1 / Cavity 2 door latch does
not lock
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
Check latch motor and switch connections/wires.
Check connections to control board.
Check wires between control board and latch. Check
operation of door switch.
Check latch for binding/mechanical latch failure.
E107
E207
Cavity 1 / Cavity 2 door latch does
not unlock
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
Check latch motor and switch operation.
Check door switch operation.
Check latch for binding/mechanical latch failure.
E115
E215
Cavity 1 / Cavity 2 temperature in
unlocked cavity too high
Temperature in unlocked cavity exceeds the
allowable temperature. Oven will stop heating
and door will lock. When temperature reaches
allowable range, door latch unlocks, error is
cleared, and oven will resume heating.
Check element operation.
Check temperature sensor resistance; replace sensor if
necessary.
Check for stuck relays.
Replace control module, if necessary.
