7.3 INDICATOR LIGHTS
The fryer’s indicator lights serve a diagnostic purpose. All lights are lit when the fryer is working properly. (The green light on the control panel will cycle on and off as the fryer calls for heat). Use the following procedures to isolate problems indicated by light combinations. Lighting sequences not listed are beyond the scope of operator correction; call an authorized service agent.
Turn the temperature dial to 400°F (204°C) to ensure the sensor will demand heat. Check all indicator lights in the fryer cabinet and on the control panel. [Older units may have power and reset switches with different colored lights (orange, amber, red, etc.). Substitute the light color of the old switch with the respective "green light" switch in the following troubleshooting procedures. The control panel light colors haven’t changed.]
