SMS computer only.

If the fryer still fails to turn ON when the

authorized service agent.

switch is defective.
2. If the KFC-1 SMS computer displays
HELP, reset high-limit thermostat
(located in the fryer cabinet under the

Ensure at least one product button is lit on
the computer. If not, press product buttons
until one button is lit.
