IGNITER, ELECTRODE TESTING AND REPLACEMENT
With the pilot not in operation (no pilot flame) you can check the igniter and electrode circuit by viewing pilot
thru the sight glass located on the inner door and observing the spark action.
SERVICE PROCEDURE ED-IV
Igniter and Electrode Testing
and Replacement
Step 1. Remove outer jacket door.
Step 2. Repeatedly depress the igniter button while viewing the pilot thru the sight glass. If a spark is
present, the circuit is OK. If there is no spark, proceed to step 3.
Step 3 Remove white wire from igniter. Hold the igniter lead from the gas valve to an unpainted surface
such as the feed line or gas valve and depress the igniter. If there is a spark, the igniter is OK,
the pilot is not functioning and must be replaced, see SERVICE PROCEDURE ED-III for pilot
replacement. If no spark is present the igniter is not functioning and the control must be replaced,
see SERVICE PROCEDURE ED-V
