1.10.3 Improper Temperature Control
Temperature control, including the melt cycle, 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 controller itself, and the ignition module.
Improper temperature control problems can be categorized into melt cycle problems and failure to control at
setpoint problems.
MELT CYCLE PROBLEMS
I
nitiation of the melt cycle with 3000 controllers is automatic. Problems may originate from the controller
itself, the temperature probe, or a malfunctioning heat relay on the interface board.
FAILURE TO CONTROL AT SETPOINT
Problems in this category may be caused by the temperature probe, the interface board, or the controller.
1.10.4 Controller Malfunctions
RECOVERY TIME
Recovery time – is a method of measuring a fryer's performance. Put simply, it is the time required for the
fryer to increase the oil temperature from 250ºF to 300ºF (121ºC to 149ºC). This range is used as a standard
since ambient kitchen temperatures can affect the test if lower ranges are used.
The 3000 controller performs the recovery test each time the fryer warms up. An operator can view the
results of the test any time the fryer is above the 325ºF (163ºC) point by pressing the INFO button once when
the fryer is on. The test results will be displayed in the controller's LED panel in minutes and seconds. The
maximum acceptable recovery time for OCF30™ series gas fryers is two minutes and twenty-five seconds
(2:25).
1.10.5 Filtration Malfunctions
The majority of filtration problems arise from operator error. One of the most common errors is placing the
filter pad on the bottom of the filter pan rather than over the filter screen.
Whenever the complaint is "the pump is running, but no oil is being filtered," check the installation of the
filter pad, including that the correct size is being used. While you are checking the filter paper/pad, verify
that the O-rings on the filter pan suction tube are present and in good condition. Missing or worn O-rings will
allow the pump to suck air and decrease its efficiency.
If the pump motor overheats, its thermal overload will
trip and the motor will not start until it is reset. If the
pump motor does not start, press the red reset switch
located on the front of the motor. If the pump then
starts, something caused the motor to overheat. It may
be that several frypots in a large battery of fryers were
being filtered one after the other and the pump became
hot. Letting the pump cool down for at least a half-
hour is all that is required in this case. More often, the
pump overheated for one of the following reasons:

Shortening that remained in the pan, after
previous filtering, solidified in the suction
tube recess in the bottom of the pan or the
suction tube, itself. Adding hot oil to the pan and waiting a few minutes will usually correct this
problem. A flexible wire can be used to clean out the suction tube and the recess in the bottom of the
pan. NEVER use compressed air to blow solidified shortening out of the suction tube!
