unless testing requires power and/or gas.

Description of Fault Codes for EOC III

Each fault code consists of 4 digits and is structured as follows:
st
1 (Leftmost) Digit:
Primary Failure System
1 – Local to Control System
3 – Sensor or Meat Probe
4 – Input to Control System
9 – Door Lock
If a fault is detected, then one of the following three messages will be scrolled on the display:
FAULT DETECTED PRESS ENTER TO TRY AGAIN. This message displays when a fault is detected while a
cooking function is active. Clear by pressing the Cancel keypad.
FEATURE NOT AVAILABLE. This message displays when a fault is detected while entering data during initial
programming and also when a locked out function is detected. Clear by pressing any key.
FAULT DETECTED DISABLE POWER TO CLEAR. This message displays when a runaway temperature condition
is detected while the control is in idle mode. Press any key to clear the message, but the fault remains until the
control senses a Power-On reset.
