CHAPTER 1: SERVICE PROCEDURES

1.9.3 Improper Temperature Control (cont.)

MELT CYCLE PROBLEMS

NOTE: In early 1999, PC board melt cycle timers replaced melt-cycle timer motors in new fryers.

See Section 1.8.8 for retrofit information.

In fryers equipped with thermostat controls, the melt cycle is controlled by a mechanical timer or a PC board. Three components that that can fail are the melt-cycle timer, the melt-cycle timer microswitch or the control panel melt cycle On/Off switch. Isolate the defect and replace defective component.

In fryers equipped with computers, the problem may be with the computer itself, the temperature probe, or a malfunctioning heat relay on the interface board. Refer to the troubleshooting tables in this chapter.

FAILURE TO CONTROL AT SETPOINT

In fryers equipped with thermostat controls, the problem will be with the thermostat itself. Possible causes are that the thermostat is out of calibration, the knob or flexible shaft is loose on the thermostat shaft, a thermostat wire is disconnected or broken, or the thermostat is defective. Refer to Section 1.7 for instructions on calibrating the thermostat.

In fryers equipped with other types of controls, the problem may be with the temperature probe, the interface board, or the controller. Refer to the troubleshooting tables in this chapter.

1.9.4 Computer-Related Problems

Computer Magic III.5 Features

Sensitivity or "Stretch Time"

Sensitivity or stretch time is a programmable feature that increases the cook time countdown based on variations in the oil temperature from the setpoint.

The sensitivity for each product button has 10 settings (0 through 9). A "0" sensitivity setting will disable the feature (no change in cooking time), while a nine will provide the highest sensitivity or most change. The correct sensitivity for any product is based on the product, its density, the setpoint temperature, and the customer’s own requirements.
