SUGGESTED CORRECTIVE ACTION PROCEDURE
PROCEDURE: Before proceeding, perform steps 1 through 3 of “To
Enter Diagnostics Mode.”
To Verify Door Switch:
1.
While in Diagnostics, open the oven door. “0” should appear in the
second clock digit from the left. Close the oven door. The clock digit
should toggle to “1.”
If the digit did not toggle, go to Step 2.
If the digit did not toggle after replacing the door switch, go to
Step 4.
If the digit did not toggle after replacing the door switch harness, go
to Step 6.
If the digit did toggle, door switch is operating correctly.
2.
Unplug oven or disconnect power.
3.
Replace door switch. (If door switch is integral to the door latch
motor assembly, replace the entire door latch motor assembly.) Go to
Step 8.
4.
Unplug oven or disconnect power.
5.
Check integrity of all harness wires and connections between the
appliance manager and the door/latch assembly. Ensure no shorted
wires to chassis.
If the wiring is bad, replace the door switch harness. Go to Step 8.
If the wiring is good, go to Step 8.
6.
Unplug oven or disconnect power.
7.
Replace appliance manager. Go to Step 8.
8.
Replace all parts and panels before operating.
9.
Plug in oven or reconnect power.
10. Enter into Diagnostics mode by pressing OFF > OFF > START.
Repeat Step 1 above.
To Verify Door Latch Switch/Motor Assembly:
1.
While in Diagnostics, press the CLEAN key within the first
120 seconds of powering up to cycle the latch motor to the locked
position. “1” should appear in the first clock digit from the left when
locked. Press the CLEAN key to cycle the latch motor to the
unlocked position. The clock digit should toggle to “0.”
If the digit did not toggle, go to Step 2.
If motor runs continuously, wait until motor reaches the
unlocked position, open the door, press the OFF key, go to
Step 2.
If motor did not run, go to Step 8.
If the digit did not toggle after replacing the door latch motor
assembly, go to Step 4.
If the digit did not toggle after replacing the door latch switch
harness, go to Step 6.
If the digit did toggle, door latch switch is operating correctly.
2.
Unplug oven or disconnect power.
3.
Replace door latch motor assembly. Go to Step 11.
4.
Unplug oven or disconnect power.
5.
Check integrity of all harness wires and connections between the
appliance manager and the door latch switch. Ensure no shorted
wires to chassis.
If the wiring is bad, replace the door latch switch harness. Go to
Step 11.
If the wiring is good, go to Step 11.
6.
Unplug oven or disconnect power.
7.
Replace appliance manager. Go to Step 11.
8.
Unplug oven or disconnect power.
9.
Check integrity of latch mechanism from cam to latch pawl and door
slot. Ensure that pawl aligns with the door slot. Correct any
mechanical malfunction.
10. Check continuity of the latch motor and of electrical connections
between appliance manager P8 and motor. If continuity is present,
replace appliance manager. Go to Step 11. If continuity is not
present, go to Step 11.
11. Replace all parts and panels before operating.
12. Plug in oven or reconnect power.
13. Enter into Diagnostics mode by pressing OFF > OFF > START.
Repeat Step 1 above.

SUGGESTED CORRECTIVE ACTION PROCEDURE
PROCEDURE: Before proceeding, perform steps 1 through 3 of “To
Enter Diagnostics Mode.” Ensure AM software, UI software and
EEPROM CHECKSUM versions appear on the lower text line. If AM
software version does not appear, UI and AM may not be
communicating.
1.
Unplug oven or disconnect power.
2.
Unplug meat probe and plug in oven or reconnect power. If error
goes away, the meat probe sensing line is grounded.
3.
Unplug oven or disconnect power.
4.
Check the harness and probe jack for a short to ground.
5.
Open the back panels and make sure the P6 connector on the
appliance manager and the P2 connector on the user interface are
fully inserted.
If not, plug in connectors and go to Step 9.
If fully plugged in, go to Step 6.
6.
Visually inspect all of the wires between P6 on the appliance
manager and P2 on the user interface. Make sure the wires are not
cut or pinched. If the wires appear to be intact, perform a continuity
check between P6-1 of the appliance manager and P2-1 of the user
interface board. Do the same for P6-2 (AM) to P2-2 (UI), P6-4 (AM) to
P2-4 (UI), and P6-5 (AM) to P2-5 (UI). All of the checks should result
in a reading of less than 5
Ω
..
If any of these checks fail, go to Step 8.
If these checks pass, reconnect P2, then go to Step 7.
7.
Replace the appliance manager. Ensure all connectors are properly
seated; then go to Step 9.
8.
Replace the wiring harness (signal) and go to Step 9.
9.
Ensure all wiring connections are made.
10. Replace all parts and panels before operating.
11. Plug in oven or reconnect power.
12. Observe for longer than 1 minute.
13. If the error does not appear, initiate a bake cycle. Let the cycle run at
least 1 minute.
If no error occurs, cancel the cycle. The problem has been repaired.
If the error occurs again, restart the troubleshooting procedure at
Step 1 (except in Step 7 replace the user interface board if the
appliance manager has already been replaced).
