Corrective Action

This is normal for fryers equipped with CM III.5 computers and Digital Controllers. The default operational mode for these controllers is for the elements to cycle on and off until the temperature in the frypot reaches 180°F (82°C). In CM III.5 computers, CYCL will appear in the display when in the melt-cycle mode Refer to the separate Frymaster Fryer Controllers User's Manual for the procedure for canceling the melt-cycle for the particular controller installed on your fryer.

In fryers equipped with Solid State (Analog) controllers, the melt-cycle is controlled manually by means of the rocker switch to the right of the temperature control knob. If not using solid shortening, press the rocker switch to the OFF position to turn off the melt-cycle.

This fryer is equipped with a drain safety switch that prevents the heating element from being energized if the drain valve is not fully closed. Verify that the drain valve is fully closed. Determining which specific component is beyond the scope of operator troubleshooting. Call FASC. Determining which specific component is malfunctioning is beyond the scope of operator troubleshooting. Call FASC.

The fact that the heat indicator is ON indicates that the controller is functioning properly and is calling for heat. The high-limit thermostat functions as a normally closed switch. If the thermostat fails, the "switch" opens and power to the elements is shut off. If the contactor fails to close, no power is supplied to the elements. Determining which component has failed is beyond the scope of operator troubleshooting. Call FASC.
