SECTION 2. MAINTENANCE

2-1. INTRODUCTION

This section provides procedures for the checkout 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.

2-2. 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.

2-3 HIGH TEMPERATURE

 

LIMIT CONTROL

The high temperature limit control is a safety, manual reset control

(Gas Units)

that senses the temperature of the shortening. If the shortening

 

temperature exceeds 425°F (218°C), this switch will open

 

and shut 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.

 

This will allow heat to be supplied to the frypot once again.

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.

 

Checkout:

 

1. Remove electrical power supplied to 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.
