FAULT FINDING
In the event of an electrical fault carry out the preliminary electrical system checks i.e. earth
continuity, polarity, and resistance to earth.
Use each chart to locate the fault causing the dryer to operate incorrectly as follows:
Chart No.

2
Motor runs but full sequence control does not produce ignition spark.
3
Motor runs, Full Sequence Control produces ignition sparks, but gas does not ignite.
4
Motor runs, gas ignites but burns for only a short period.
