CHAPTER 1: SERVICE PROCEDURES

1.9 Troubleshooting and Problem Isolation

Because it is not feasible to attempt to include in this manual every conceivable problem or trouble condition that might be encountered, 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 likely encountered can be grouped into six broad categories:

1.	Pilot/Ignition failures	5.	Filtration problems
2.	Improper burner functioning	6.	Leakage

3.Improper temperature control

4.Computer-related problems

The probable causes of each category are discussed in the following sections. Troubleshooting charts are included at the end of the chapter to assist in identifying some of the more common problems.

1.9.1 Pilot/Ignition Failures

There are two categories: no pilot flame and unreliable flame.

No pilot flame

1.No gas or insufficient gas supply.

2.Clogged pilot orifice.

3.Air in gas lines (usually in new installations).

4.Open or grounded high limit.

Unreliable flame

1.Loose/corroded wire connections.

2.Low or no voltage out of thermopile / thermocouple (CE units).

3.Defective gas valve.
