Frymaster 45, 35 manual Troubleshooting and Problem Isolation, Typical Problems, Pilot Failure

21.In units with multiple frypots, add a bead of silicon along the joint between the frypots to ensure a seal. Then, insert the top connecting strip.

22.Reverse Steps 1-25 to reassemble the fryer.

1.5 Troubleshooting and Problem Isolation

Because it is not feasible to include every issue that might occur, this section is intended to provide technicians with a general knowledge of the broad problem categories associated with this equipment and the probable causes of each. With this knowledge, the technician should be able to isolate and correct any problem encountered.

1.5.1 Typical Problems

You are likely to encounter problems in these broad categories:

1.	Pilot Failure	6.	Computer Malfunction
2.	Ignition Failure	7.	Filtration Malfunction
3.	Improper Burner Function	8.	Leakage
4.	Improper Temperature Control	9.	Basket Lift Malfunction
5.	Gas Valve Malfunction

Read the following sections to learn more about each category. A series of troubleshooting guides is also included at the end of the chapter to assist in identifying some of the more common problems. In addition, Section 1.5.2 will guide technicians through interpretation of digital controller lights, helpful in diagnosing problems.

Pilot Failure

There are two types of pilot failure: no pilot flame and unreliable pilot flame.

No pilot flame:		Unreliable pilot flame:
•	Insufficient gas supply	• Open or grounded high limit
•	Clogged pilot orifice	• Loose or corroded wire connections
• Air in gas lines (usually in new installations).		•	Low or no voltage out of thermopile
		•	Bad gas valve.

Ignition Failure

Ignition failure occurs when the gas valve no longer receives power, the gas supply stops, or the pilot flame goes out. Solid-state controllers indicate ignition failure by illuminating the heat light and trouble light simultaneously. Computers and digital timers will read HELP to indicate ignition failure. There are three primary areas of focus in diagnosing and correcting ignition failure:

1.The gas and electrical power supplies

2.The electronic circuits

3.The gas valve.
