General Troubleshooting Guide (Continued)
PROBLEM
5. The upper platen will not stay
in the raised position.
6. The product is under-cooked,
overcooked, or cooking
unevenly.
7. The control is displaying a
fault.

Control Board and Terminal Cleaning

Under several occasions we have found controls and
thermocouples replaced when faults such as TOO
COOL, TOO HOT, and thermocouple faults are
displayed. We have found that using contact cleaner
on the terminals, connectors, and board surfaces will
clear these problems. If contact cleaner is used,
please be sure all components are DRY before
restoring power to the unit.
This option is suggested prior to component
replacement.
