Troubleshooting and Problem Isolation
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.
Problems you are likely to encounter can be grouped into these broad categories:
1. Pilot failures
2. Improper burner functioning
3. Improper temperature control
4. Leaking
The probable causes and corrective actions for each category are discussed in the following sections.
1.8.1 Pilot Failures
Pilot failures fall into one or the other of two categories – failure to light or failure to remain lit.
Pilot Fails to Light
1. Gas is not being supplied to the valve: Check for a closed gas cutoff valve upstream of the gas
valve. Also verify that the gas line quick disconnect fitting at the rear of the fryer (if so
equipped) is properly connected.
2. Blocked pilot orifice: If gas is reaching the valve but the pilot will not light, check for an
obstruction in the pilot orifice, especially in new installations. If the orifice is clear, check to be
sure that the pilot adjustment screw is not completely closed.
