6.7.3 Improper Temperature Control

Temperature control is a function of several interrelated components, each of which must operate correctly. The principle component is the temperature probe. Other components include the interface board, the water level sensors, the computer, and the ignition module. Whatever the cause, the symptom is failure of the unit to attain or maintain setpoint temperature.

The unit will not call for heat unless the computer senses that the unit is full of water. Sensing is accomplished when the water level in the cookpot contacts the upper water level sensor, grounding it. If the mineral content of the water is unusually low, such as with distilled, purified, or highly filtered water, the water will not ground the sensor. If this is the cause, adding approximately ⅛-cup of baking soda to the water will solve the problem.

Similarly, if the upper water level sensor becomes encrusted with lime, starch, or some other build- up, it will not ground properly. The solution is to clean the water level sensors thoroughly with a Scotchbrite™ or similar nylon scouring pad.

6.7.4 Computer-Related Problems

The computer used in FBKR18 Series rethermalizers is a specially modified Computer Magic III computer, part number 806-9396. Standard CM III computers will not operate this equipment correctly. The first thing to check if problems with the computer are experienced should be the part number.

Most problems concerning the computer have to do with programming it. There are three common complaints. The complaints, their causes, and corrective actions are:

1.Fryer constantly displays HI.

Cause: Setpoint incorrect or missing.

Corrective Action: Press 1650, enter the correct setpoint, then press to lock in the setpoint.

2.Temperature is displayed in Celsius.

Cause: Computer is programmed to display in Celsius.

Corrective Action: Press 1658.

3.Temperature is constantly displayed.

Cause: Computer is programmed for constant temperature display.

Corrective Action: Press i65L.
