CHAPTER 1: SERVICE PROCEDURES
1.8 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.
You are likely to encounter problems in these broad categories:
1.ignition failure,
2.improper burner function,
3.improper temperature control,
4.improper computer function,
5.improper filtration function,
6.frypot leakage, and
7.basket lift malfunction.
The probable causes of each category are discussed in the following sections. Troubleshooting guides are included in Section 1.9 to assist in identifying some of the more common problems.
1.8.1 Ignition Failure
Ignition failure occurs when the ignition module fails to sense a flame within the
There are three primary reasons for ignition failure, listed in order of probability:
1.The gas and electrical power supplies,
2.The electronic circuits, or
3.The gas valve.
The Gas and Electrical Power Supplies
The main indicators that the gas or electrical power supply is the cause of ignition failure are as follows: an entire battery of fryers fails to light, and/or there are no indicator lights illuminated on the fryer experiencing ignition failure. Verify that the quick disconnect hose is properly connected, the fryer is plugged in, the main gas supply valve is open, and the circuit breaker for the fryer electrical supply is not tripped.
