Test Cooktop Burners:
Each burner must be tested for proper lighting, proper
flame characteristics on the low setting and proper flame
characteristics on the high setting.
Test for proper ignition:
1. Push down and turn the knob to ignition symbol.
2. Verify that the ignitor/spark module clicks.
3. Once the air has been purged from the supply lines,
verify that the burner lights within four (4) seconds.
After burner lights, turn knob to the off position.
4. Test each rangetop burner in this fashion. Call Service
if any of the burners do not light.
Test flame characteristics on the low setting:
1. Push in and turn the knob to the ignition symbol until
the burner ignites.
2. Turn knob to the low setting.
3. Verify that the burner maintains a minimum, steady,
flame without going out. The flame should not lift or
blow off of the burner. It should carry over, or surround,
the entire burner.
4. Verify that the flame is the right color. It should be blue
with an inner and outer cone. “Checking Flame
Characteristics” on page 7 for more information.

goes out, does not carry over properly or is too large,
contact service.
Test flame characteristics on the high setting:
1. Push in and turn the knob to the ignitor symbol until the
burner ignites.
2. Turn knob to the high setting.

with an inner and outer cone. See Figure 6: Checking
Flame Characteristics for more information.
