2-4. HIGH TEMPERATURE This high temperature control is a safety, manual reset control,
LIMIT 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.)

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

|
could result. (See photo at left). |
2-11. REVERSING THE LID |
The gray rubber gasket surrounding the inside of the lid is de- |
GASKET |
signed 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 |
|
