the wires off of terminal #1,and reinstall them one at a time. Once

has failed
1. The temperature must be equal from top to bottom in cabinet.

1. Should the "Food Probes" fail to read any temperature you will
need to check them for breaks in the wires or separation of the
insulation.

Probes plug into for any broken pieces.
3. Pull the Socket Plate down to inspect the top of the sockets for
broken wires or corrosion.
