2 = Master Power Board (upper cavity)
3 = Slave Power Board ( lower cavity)
Type Error
F2/3 01 Initialization error - No clock module found.
001010101
02 Unknown Model ID - The power board does not support the Model ID that is trying
to be set through Technician Mode or restored by the old clock module (when
power board is being replaced).
03 General software error.
04 Communication error - The clock module does not respond in time or at all.
05 Door lock mechanism error.

13 Cavity temperature sensor found to be open/short circuit.
14
16 Cavity not heating up (sensor sees no change in temperature). Use Bake function
from cold to evaluate this fault. It takes at least 10 minutes to fault out when no
change in temperature is seen.
17 Door lock is not in its unlocked position.
Description & Possible Solution
Check connection to clock module
Replace clock module
Make sure you are setting the correct Model ID
If the problem persists, try another power board spare that may have a later
version of software in it
Once the oven is working again, check via Technician Mode that the Model ID is
correctly set - refer pg. 35
Try powering the oven off and on. If the problem persists, replace the power
board.

Check/reset thermal limiter(s) which may have cut power to the heating
elements
Check each heating element via technician mode to ensure they are operating
Replace the power board
Replace the cavity sensor
Check/reset thermal limiter(s) which may have cut power to the lock motor
Check whether the lock motor turns
Check the lock/unlock switches + connector to the power board
