This section provides troubleshooting information in the form of an easy to read table. If a problem occurs during the f rst operation of a new fryer, recheck the installation per the Installation Section of this Before troubleshooting, always recheck the operation pro- cedures per Section 3 of this manual.
1-3. TROUBLESHOOTING To isolate a malfunction, proceed as follows: Clearly def ne the problem (or symptom) and when it occurs. Locate the problem in the Troubleshooting table. Review all possible causes. Then, one-at-a-time work through the list of corrections until the problem is solved. Refer to the maintenance procedures in the Maintenance Section to safely and properly make the checkout and re- pair needed.

MAINTENANCE SECTION 2. MAINTENANCE This section provides checkout and replacement procedures, for various parts of the fryer. Before replacing any parts, refer to the Troubleshooting Section to aid you in f nding the cause of the malfunction. 1. A multimeter will help you to check electric components.
The red reset button is located under the control panel, in the front of the fryer, to the right of the drain. Once reset, the frypot starts heating.
Page 19
2-4. HIGH TEMPERATURE LIMIT CONTROL (Continued) 1103 To avoid electrical shock of property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle. Replacement 1. If the tube is broken or cracked, the control will open, shutting off electrical power.
2-4. HIGH TEMPERATURE LIMIT CONTROL (Continued) 2-5. FUSE HOLDERS 11. Pull excess capillary line from pot and tighten nut into frypot wall. Be sure capillary bulb of high limit is positioned so it does not interfere with carrier or get damaged when cleaning frypot.
The POWER/PUMP switch is a three way rocker switch with a center OFF position. With switch in the POWER position, the fryer operates. With switch in PUMP position, the f lter pump operates, but the unit will not heat. To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.
10°C, the temperature probe should be replaced. An Ohm check can be performed also. See chart at end of this section. 1. Remove electrical power supplied to the fryer. To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.
3. Unplug the connectors going to the control board. 4. Install a new control panel. The Henny Penny Fryer uses pressure as one of the compo- nents of the cooking process. Once the lid is sealed to the frypot, and the solenoid valve closes, a deadweight valve main- tains the correct pressure in the frypot.
Because of heat expansion and the pressure used for cooking process, gasket is constantly under extreme stress. Reversing the lid gasket will help to assure that the fryer will not lose pressure through leakage. 1. Put the lid in the upright position, as previously described.
2-12. LID COUNTERWEIGHT CABLES 1103 The Lid Counterweight in the back of the fryer balances the weight of the lid system to allow easier opening and closing of the lid. The weight has two cables attached to it, and weighs about 150 lbs.
2-13. PRESSURE PAD 2-10 The pressure pads are plastic strips that the lid cam presses against to seal the lid. 1. Raise the lid. 2. Remove the 4 screws securing the lid cover and remove cover 3. Push the lid cam back, off of the pressure pads. 4.
If steam leaks, check for: • Pressure pad wear • Cracked or worn gasket • Gasket installed improperly • Fryer operating above 12 psi (827 mbar) Fryer should be operating at 12 psi, or serious burns could result. Model 590/592 2-11...
Cook Cycle and opens automatically at the end of the Cook Cycle. If this valve should become dirty, or the Tef on seat nicked, pressure will not build up. The electric fryer uses a 208/240 volt 60 hertz coil (50 hertz internationally).
Page 29
6. Repair kit, Part No. 17120, is available if any of the seals must be replaced. If one seal is defective, replace all seals. Solenoid body must be removed from the fryer for replace ment of seals. Continue on to step 7.
14. If the complete valve is to be replaced, follow steps 1, 2, 3, 4, 5, 7, 8 and 9 in this section. DO NOT ATTEMPT TO REMOVE DEADWEIGHT CAP WHIILE FRYER IS OPERATING. SEVERE BURNS OR OTHER INJURIES WILL RESULT. The operating valves are located behind the lid. The valve, left of the pressure gauge, is a 14 1/2 lb.
RELIEF VALVE. HOT STEAM WILL BE RELEASED AND SEVERE BURNS WILL RESULT. 1. At the end of each day’s usage of the fryer, the deadweight valve must be cleaned. The fryer must be OFF and pressure released. Open the lid and then remove the deadweight valve cap and deadweight.
3. Clean the inside of the pipe tee with hot water. Turn the safety relief valve towards the rear of the fryer when reinstalling safety relief valve. 4. Immerse the safety relief valve in a soapy water solution for 24 hours.
Primary Heat 1103 The electric fryer requires two switching contactors: a primary and a heat contactor. The primary contactor energizes (contacts close) any time the POWER/PUMP switch is in the POWER position, and the temperature of the shortening is below ( 215°...
Page 34
4. Remove the screws securing the contactor to the bracket and remove contactor from bracket. 5. Install new contactor in reverse order. 6. Install control panel and reconnect power to the fryer and test for proper operation. Model 590/592 1103...
2-20. HEATING ELEMENTS 1103 The electric model fryer uses 2 heating elements. Heating elements are available in 208, 220/240, 380 and 415 volts. Check the data plate, on the shroud behind the lid, to determine the correct voltage elements. 1. Remove the electrical power supplied to the unit.
Page 36
2-20. HEATING ELEMENTS (Continued) 2-20 Replacement 1. Drain the shortening. 2. Remove the high limit bulb holder from the heating element inside the frypot. 3. Disconnect the heating element wires from the contactors. Label each so it can be replaced in the same position on the new element.
Page 37
2-20. HEATING ELEMENTS (Continued) 1103 10. Replace the brass nuts and washers on the heating element terminals. Tighten the brass nuts to 30 foot lbs of torque. 11. Replace heat contactor. 12. Move the element spreaders from the center of the ele ment, into a position which will spread each element apart evenly on all four sides, and tighten.
2-21. DRAIN MICROSWITCH 1/8” (4 mm) Gap 2-22 Upon pulling out on the drain handle, the microswitch should be activated and the unit will not heat, but when the handle is pushed back, the unit should operate properly. The bracket on the microswitch is slotted so it can be adjusted backward or forward.
2-22. DRAIN VALVE AND EXTENSION 1103 The drain valve opens when the drain valve handle is pulled out and drains the shortening out of the pot. Replacement 1. Using a 3/8” socket, remove the nuts securing the drain switch bracket, and pull the bracket from the studs. 2.
2-23. NYLATRON STRIPS REPLACEMENT 2-24 1. Raise the lid and remove the retention ring from one end of the lid pin. 2. Slide the lid pin from unit. 3. Lift the lid from unit. The lid weighs 80 lbs (36 kg). Take care when lifting lid to prevent personal injury.
Page 41
2-23. NYLATRON STRIPS REPLACEMENT (Continued 1103 9. Lift the front shroud up and out, over the arm of the lid. 10. Thread the new nylatron strip through the track in the front shroud. 11. Lining up the holes in the strips, f t the front shroud back over the lid arms.
