INTERPRETING DISPLAYED ERROR CODES

Programmable and Rack Timer models are able to detect some problems that might occur. If the control
panel display is showing a letter "F" followed by a number, consult the following table to determine the
problem and appropriate corrective action.

Display shows F2 Oven interior maximum temperature
exceeded.
Display shows F3 Open temperature probe.
Display shows F4 Shorted temperature probe.
Display shows F5 Bad temperature controller.
Display shows F6 Bad temperature controller.
Display shows F7 Total cook time in a program exceeds 24
hours (programmable models only).
Display shows F8 Bad temperature controller.

CONTROL PANEL ACCESS AND SHUT-OFF SWITCH

To access the control panel components, remove the screw at the top of the control panel and pull the top
of the control panel out and down (see drawing below). A wiring diagram for the oven is located on the side
of the control panel assembly. When the control panel is folded down, all power to the control panel is
cut off by a shut down switch that is located directly behind and below the control panel. To re-
energize the controls for troubleshooting, pull the white plunger on the shut down switch up.
