PROCEDURE: Before proceeding, press OFF, OFF, START to enter the Diagnostic mode and verify the error codes. TO VERIFY DOOR SWITCH: A. While in diagnostics, open the oven door. The second digit on the clock display should toggle between "1" and "0" as the door opens and closes. When door is closed display should show "1", when the door is open display should show "0". If the second digit on the clock display did not toggle, go to step B. If the digit did not toggle after replacing the door switch, go to step D. If the digit did not toggle after replacing the door switch harness, go to step F. B. Unplug oven or disconnect power. C. Replace door switch. (If door switch is integral to the door latch motor assembly, replace the entire door/latch motor assembly). Go to step H. D. Unplug oven or disconnect power. E. Check the integrity of the harness wires and connections between the appliance manager and the door/latch assembly. Ensure there are no shorted or pinched wires. If the wiring harness is pinched or damaged, replace the door switch harness. Go to step H. If wiring harness is good, go to step H. F. Unplug oven or disconnect power. G. Replace appliance manager. Go to step H. H. Replace all parts and panels before operating. I. Plug in oven or reconnect power. J. Press OFF, OFF, START to reenter the Diagnostic mode and complete checks. Repeat step A. 6-3

assembly, replace the entire door/latch motor assembly). Go to step H.
D.
Unplug oven or disconnect power.
E
. Check the integrity of the harness wires and connections between the
appliance manager and the door/latch assembly. Ensure there are no shorted
or pinched wires.
If the wiring harness is pinched or damaged, replace the door switch harness.
