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.

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
