otherwise,

A. Unplug oven or disconnect power.

B. Open the back panels and make sure the P6 and P2 connectors are fully

inserted on the appliance manager and on the lower oven user interface board.

- If they are not plugged in, plug in connectors and go to step F.

- If they are plugged in, go to step C.

C. Visually inspect all wires between P6 on the appliance manager and P2 on the

lower user interface.

- Make sure 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.
