24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES

1.8.3 Improper Temperature Control

Temperature control, including the melt cycle, is a function of several interrelated components, each of which must operate correctly. The principal component is the temperature probe. Depending upon the specific configuration of the fryer, other components may include the Thermatron 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.

Failure to Control at Setpoint

In fryers equipped with a Thermatron temperature controller, the #1 problem may be with the temperature probe improperly positioned. Other causes may be the Thermatron board or the potentiometer. Possible causes are that the potentiometer is out of calibration, or the temperature probe or Thermatron board is defective. Refer to Section 1.6 for instructions on calibrating the Thermatron temperature controller.

1.8.4 Filtration Problems

Whenever the complaint is "the pump is running, but no oil is being filtered", check the filter paper or filter leaf (screen) connections and ensure they are properly connected. Ensure the filter paper or filter leaf is not clogged with food debris or sediment, and is properly assembled.

If the pump motor overheats, a circuit breaker in the filter circuit will trip and the motor will not start until it is reset. If the pump motor does not start after pressing the circuit breaker, press the red reset switch located on the rear of the motor. If the pump then starts, something caused the motor to overheat. Maybe several frypots were filtered one after the other and the pump got hot. Letting the motor 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 was solidified in the filter leaf or filter lines.

The operator attempted to filter unheated oil or shortening. Cold oil and shortening are thicker and cause the pump motor to work harder and overheat.

If the motor runs but the pump does not, there is a blockage in the pump. An incorrectly assembled filter leaf allows food particles and sediment to pass through the filter pan and into the pump. When sediment enters the pump, the gears bind up causing the motor to overheat, tripping the thermal overload. Solidified shortening in the pump will produce the same result.
