CHAPTER 1: SERVICE PROCEDURES Functional Description The 45 Series fryers contain a welded steel (stainless or cold rolled) frypot that is directly heated by gas flames that are diffused evenly over its lower surface by ceramic targets. The flames originate from orifices in a U-shaped burner manifold positioned beneath the frypot. The orifice diameters differ for natural and propane gas as indicated in the table below (see Page 2-5 for a complete list of available orifices).
CONTROL OPTIONS 45 Series fryers may be equipped with thermostat controllers, analog controllers, digital controllers, basket lift timers, or Computer Magic III computers. In fryers equipped with thermostat controls, the fryer and melt cycle are turned on and off by means of rocker switches and the temperature is set by means of a knob connected directly to the frypot- mounted thermostat.
(setpoints). The temperatures are programmed by means of a keypad on the face of the controller. All 45 Series fryers are equipped with a high-limit thermostat. In the event that the fryer fails to properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to...
Moving a fryer filled with cooking oil/shortening may cause spilling or splattering of the hot liquid. Follow the draining instructions in Chapter 4 of the 45 Series Gas Fryer Installation and Operation Manual before attempting to relocate a fryer for servicing.

2. Ensure the fryer ON/OFF Switch is in the OFF position, then light the pilot. (Refer to Chapter 3 of the 45 Series Gas Fryer Installation and Operation Manual for detailed lighting instructions.) 3. Insert a good grade thermometer or pyrometer into the frypot so that it touches the thermostat guard.
6. When the cooking oil/shortening temperature reaches 325ºF (162ºC), turn the flexible shaft slowly clockwise until the burner shuts off. 7. Allow the fryer to sit for a few minutes, then slowly turn the flexible shaft counterclockwise un- til the burner lights. 8.
4. Remove the controller/computer by lifting it from the hinge slots in the fryer control panel frame. 5. Reverse the procedure to install a new controller/computer. 1.8.2 Replacing the Operating Thermostat CAUTION The thermostat must be calibrated after installation is complete. Refer to Section 1.7 for calibration instructions.
3. Remove the screws from the upper left and right corners of the control panel. The panel is hinged at the bottom and will swing open from Unplug harness the top. 4. Unplug the wiring harness from the back of the controller and disconnect the grounding wire.
9. Reverse steps 1 through 7 to install the replacement. 1.8.5 Replacing the High-Limit Thermostat in Fryers with Other Than Thermostat Controls 1. Disconnect the fryer from the electrical power supply. Unplug harness 2. Drain the frypot. 3. Remove the screws from the upper left and right corners of the controller panel.
3. Disconnect the 9-pin connector and remove the control panel from the fryer by disengaging its tabs from the hinge slots in the mounting frame. 4. Carefully press the light out from the back of the control panel. Disconnect one wire at a time and reconnect it to the replacement light until all wires are transferred.
1.8.9 Replacing Burner Ceramic Targets DANGER Drain the frypot or remove the handle from the drain valve before proceeding further. Disconnect fryer from electrical and gas supplies. On FM45 fryers, remove square-drain sections as necessary to expose burner. Disconnect the wires from the gas valve terminal block, marking each wire to facilitate recon- nections.
2. Disconnect the wires from the gas valve terminal block, marking each wire to facilitate recon- nections. 3. Remove the high-limit thermostat wire from the gas valve pilot coil. 4. Disconnect the pilot gas line fitting from the gas valve. 5.
1.8.12 Replacing the Frypot 1. Drain the frypot. 2. Remove all accessories (e.g., frypot covers, basket lift arms, etc.) from the fryer. 3. Disconnect the fryer from gas and electrical supplies. 4. Remove the screws from the top cap above the control panel and lift it up and off the fryer(s). 5.
2) and the high-limit thermostat leads (pins 6 and 8) from the plug. Leave all other wires con- nected. Leave the interface board lying on the shield. 13. Remove the louvered frame above the control panel opening. 14. Remove the screws securing the component shield to the fryer. 15.
Problems you are likely to encounter can be grouped into seven broad categories: 1. Ignition failures 5. Filtration problems 2. Improper burner functioning 6. Leakage problems 3. Improper temperature control 7. Basket Lift malfunctions. 4. Computer-related problems The probable causes of each category are discussed in the following sections. A series of Trouble- shooting Guides (decision trees) is also included at the end of the chapter to assist in identifying some of the more common problems.
Page 21
1.9.2 Improper Burner Functioning With problems in this category, the burner ignites but exhibits abnormal characteristics such as “popping,” incomplete lighting of the burner, fluctuating flame intensity, and flames “rolling” out of the fryer. “Popping” indicates delayed ignition. In this condition, the main gas valve is opening but the burner is not immediately lighting.
Page 22
If the fryer’s gas and air supplies are okay, the problem most likely is with one of the electrical com- ponents. Examine the controller for signs of melting/distortion and/or discoloration due to excessive heat build-up in the fryer. (This condition usually indicates improper flue performance.). A discol- ored or distorted controller is automatically suspect and should be replaced.

Cause: Computer is compensating for oil temperature via the sensitivity setting. Corrective Action: Reprogram sensitivity setting for each product in accordance with program- ming instructions in Chapter 3 of the 45 Series Gas Fryer Installation and Operation Manual. 1.9.5 Filtration Problems The majority of filtration problems arise from operator error.
Page 25
• Shortening was solidified in the pan or filter lines. • The operator attempted to filter oil or shortening that was not heated. Cold oil and shortening are thicker and cause the pump motor to work harder and overheat. If the motor tries to run but the pump does not, there is a blockage in the pump. Incorrectly sized or installed paper will allow food particles and sediment to pass through the filter pan and into the pump.
1.9.7 Basket Lift Malfunctions 45 Series fryers may optionally be equipped with automatic basket lifts to ensure uniform cooking times. The lifts may be configured for manual control or for control via a Basket Lift Timer or Computer Magic III computer. Basket lifts will always come in pairs, although each operates inde- pendently.
Page 27
In units with Computer Magic III or Basket Lift Timers, timing circuitry in the controller initiates and stops basket lift operation depending upon the variables programmed by the operator. When the product button is pressed, the timing circuitry activates a coil in the basket lift relay to supply power to the motor.
Page 28
A modular basket lift consists of a toothed rod to which the basket lift arm is attached, a reversible- drive gear motor, and a pair of roller activated microswitches. The gear motor engages the teeth in the rod, moving it up or down depending upon the direction of rotation of the motor. Microswitches at the upper and lower limits of movement stop the motor when the basket is in the full up or full down position and also reverse the direction of current flow thus reversing the motor direction.
Page 29
230/240/250V Modular Basket Lift Assembly BINDING/JAMMING PROBLEMS Noisy, jerky or erratic movement of the lifts is usually due to lack of lubrication of the rods and their bushings. Apply a light coat of Lubriplate™ or similar lightweight white grease to the rod and bushings to correct the problem.
Page 30
ELECTRONICS PROBLEMS This category encompasses problems with the relays, microswitches, capacitors, resistors, interface board, wiring, and controls. Troubleshooting the electronics of both bell crank and modular basket lifts is simply a process of verifying current flow through the individual components up to and in- cluding the motor.

1.9.8 Interpretation of Digital Controller Lights Power light on, heat light cycling, trouble light off, and melt light on: • If fryer oil temperature is below 180ºF (82ºC), the lights indicate the unit is operating nor- mally. • If the oil temperature is above 180ºF (82ºC) and the heat light continues to cycle as if in the melt cycle, this may indicate a defective probe circuit or low incoming 12VAC to the con- troller.
