"F3x" an oven probe problem, and "F9x" a latch motor problem.
Suggested
Corrective
Action
- Check RTDsensor probe and replace if necessary. If oven is overheating,
disconnect power. If oven continues to overheat when power is re@plied,
replace the EOC.
- PressClear key.
- If fault returns, replace the keyboard (membrane).
- If the problem persists, replace the EOC.
- PressCLEAR key.
- Disconnect power, wait 10 seconds and reapply power. If fault returns
upon power-up, replace EOC.
- Disconnect power. Verify the flat cable connection between the keyboard
membrane and the EOCon J2 and J3.
- If the problem persists, replace the EOC.
- If the connection is good but the problem persists, replace the keyboard
membrane switch).
- Check wiring in probe circuit for possible open condition.
- Check RTDresistance at room temperature (compare to probe resistance
chart). If resistance does not match the chart, replace the RTD sensor
)robe.
- Let the oven cool down and restart the function
- Replace the EOC.
- PressCLEAR key.
- If CLEARkey does not eliminate problem, turn off power for 30 seconds
then turn on power.
- Check wiring of Lock Motor, Lock Switch and Door Switch circuits.
- Unplug the lock motor from the board and apply power (L1)directly to the
Lock Motor. If the motor does not rotate, replace Lock Motor Assembly.
- Check Lock Switch for proper operation (do they open and close, check
with ohmmeter). The Lock Motor may be powered as in above step to
open and close Lock Switch. If the Lock Switch is defective, replace Motor
Lock Assembly.
- If all above steps fail to correct situation, replace the EOC in the event
of a motor that does not rotate.
- PressSTOP key.
- Turn power off for 30 seconds then turn power on. If the door motor
never stops rotating, or if the F95 error comes back again, verify wiring
of the motor. If wiring is good, replace the EOC.
- If the problem persists, replace the motor door latch assembly.
