2-4. HIGH TEMPERATURE
LIMIT CONTROL

This high temperature control is a safety, manual reset control,
which senses the temperature of the shortening. If the shorten­ing temperature exceeds 425°F (218°C), this switch opens
and shuts off the heat to the frypot. When the temperature of
the shortening drops to a safe operation limit, manually reset
by pressing the red reset button. 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.

Checkout

Before replacing a high temperature limit control, check to see
that its circuit is closed.

The shortening temperature must be below 380°F (193°C)
to accurately perform this check.

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.

2. Remove the control panel.

3. Remove the inner heat shield.

4. Remove two nuts securing the high limit bracket to unit,
and pull the bracket from the unit.

5. Remove two screws securing the high limit to the bracket,
and remove the high limit from the bracket.

6. Remove the two electrical wires from the high temperature
limit control.

7. Manually reset control, then check for continuity between
the two terminals after resetting the control. If circuit is
open, replace control, then continue with this procedure. (If
the circuit is closed, high limit is not defective. Reconnect
the two electrical wires.)

PANEL-HENNY PENNY

2-9. PRESSURE REGULATION

Should the control panel become inoperative, follow these
instructions for replacing the board.

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.

2. Remove the two screws securing he control panel and lift
panel up and out

4. Install a new control panel.

The Henny Penny Fryer uses pressure as one of the compo­nents of the cooking process. Once the lid is sealed to the
frypot, and the solenoid valve closes, a deadweight valve main­tains the correct pressure in the frypot.

The lid has minimal and limited maintenance and repair proce­dures, which are addressed in the following sections.

The following is a routine maintenance schedule for the Lid:

Every 90 days

• Clean and reverse the lid gasket

Yearly Inspection

• Check Lid Gasket for splits and tears-replace if necessary

• Check Pressure Pads for wear-rotate if necessary

• Check Cam Slide Guides-replace if worn or broken

• Check Lid Rollers-replace if cracked or damaged

1103 2-7

Model 590/592

2-10. TILTING THE LID
UPRIGHT

2-11. REVERSING THE LID
GASKET

The Lid Assembly is easily tilted up for cleaning or servicing.

1. Raise the lid and remove racks and carrier.

2. Grasping the lid handle, lift the front of the lid up until it
stops in an upright position.

Be sure the metal arm on the left side of the lid is in the

vertical position holding lid upright, or severe injuries
could result. (See photo at left).

The gray rubber gasket surrounding the inside of the lid is de­signed to be reversed.

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. Using a thin blade screwdriver, pry out the gasket at the
corners. Remove the gasket.

Check the gasket for any tears or nicks. If the gasket is

damaged it needs to be replaced.

Be sure the metal arm on the left side of the lid is in the

vertical position holding lid upright, or severe injuries
could result. (See photo in Tilting Lid Upright section)

3. Clean the gasket and gasket seat with hot water.

4. Rotate the gasket with the opposite side facing out.

Install the 4 corners of the lid gasket. Smooth gasket into

place, working from the corners towards the middle of each
side.

2-12. LID COUNTERWEIGHT
CABLES

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. (67.5 Kg).

1. Using a 3/8” socket, remove the nuts securing rear shroud
of the fryer and remove the shroud.

2. Using Phillips-head screwdriver, remove screws securing
the top cap and remove cap.

3. Raise the lid.

4. Unscrew broken cable from the weight assembly and the
bracket attached to the fryer, and remove broken cable.

5. Screw a 5/16” nut on each end of the new cable.

6. Using a wrench, screw new cable into the weight assembly
until tight.

7. Using a 1/2” wrench, tighten nut (already threaded on the
cable) against weight assembly, securing the cable into the
weight assembly.

8. Pull cable over pulley and down behind weight assembly.

9. Insert cable into the hole in the bracket and screw a 5/16”
nut onto end of cable. Tighten cable, by screwing the cable
through this nut until the weight assembly becomes
level.

The safety cable should now have slack in it with the
weight assembly level.

10. Tighten nut against the top of the bracket, securing the
cable.

11. Replace the top cap and rear shroud. The repair is now
complete.

2-14. LID ADJUSTMENT

If steam leaks out from around the lid gasket, the pressure pads
could be worn or broken. If the pressure pad is worn, but not
broken, it can be reversed 180 degrees, and the other end of the
pad used. See Pressure Pad Section.

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.

1103 2-11

Model 590/592

2-15. SOLENOID VALVE

This is an electro-mechanical device that causes pressure to be

held in the frypot. The solenoid valve closes at the beginning

of the 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).

To avoid electrical shock or property damage, move the

power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.

Coil Check Procedure

Remove the solenoid wires from the wire nuts which are found
behind the control panel. Check across wires.
RESULTS
208/240 Volt, 60 Hertz 150 Ohms
208/240 Volt, 50 Hertz 230 Ohms

Replacement

1. Remove the right side panel.

2. Remove the “tru-arc” retaining clip on top of coil housing.

3. Remove the cover.

2-19. CONTACTORS

Primary

Heat

30 31 32

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 420° F

( 215° C). The high limit cuts power at the primary contactor
if the temperature of the shortening is above 420
The primary contactor supplies power to one side of the heat
contactor.

The heat contactor is controlled by the computer controller.
When the controller calls for heat, the heat contactor applies
power to one side of the heating elements. When the heat con­tactor and primary contactor are energized (contacts closed) the
electric heating elements heat the shortening.

The photo shows a mercury heat contactor, but CE coun-
tries will have an electromechanical heat contactor.

Checkout

1. Remove electrical power supplied to the fryer.
