INTRODUCTION

This section provides procedures for the check out and

 

 

 

replacement of the various parts used within the fryer. Before

 

 

 

replacing any parts refer to the Troubleshooting Section. It will aid

 

 

 

you in determining the cause of the malfunction.

MAINTENANCE HINTS

1. You may need to use a multimeter to check the electric

 

 

 

components.

 

 

 

2. When the manual refers to the circuit being closed, the

 

 

 

multimeter should read zero unless otherwise noted.

 

 

 

3. When the manual refers to the circuit being open, the

 

 

 

multimeter will read infinity.

HIGH TEMPERATURE

 

 

 

LIMIT CONTROL

This high temperature control is a safety, manual reset control,

 

 

(Gas Units)

which senses the temperature of the shortening. If the short-

 

 

 

ening temperature exceeds 425°F (218°C), this switch opens

 

 

 

and shuts off heat to the frypot. When the temperature of the

shortening drops to a safe operation limit, the control must be manually reset by pressing the red reset button. The red reset button is located under the control panel, in the front of the fryer. (Figure 2-1). This allows heat to be supplied to the frypot.

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

Figure 2-1

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

To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

1. Remove the control panel. Figure 2-2.
