• The burner goes to lock-out because of:

a) Flame failure:

b) The spark is irregular or not present:

c) The air pressure switch does not close its
contact.
Uneven baking.

The burner is equipped with multiple
interlocked safety devices. In the event of a
failure of the flame or any blockage of the
combustion air supply, the burner will "lock
out" in the safety condition.

• Air has not been bled from the gas line.

• Porcelain insulators cracked (very little

crack is enough).

• Spark probe grounded.

• It may be disconnected, incorrectly set or

defective or maybe the blower is not
running.

Make sure that the grills do not obstruct the air
flow. Do not use foil on the grills.

Verify the temperature of the oven by using an
oven thermometer and make sure that it is even
with the thermostat setting.

The steam works in the oven but the light
inside the steam button does not lite.
If steam device of the oven does not work
properly.

If the oven is baking too much on the sides, it is
possible that the fan is not cycling properly.
(Verify if the motor turns 2.5 minutes in a
direction, stops 30 seconds and starts for 2.5
minutes in the opposite direction.

Replace the inside button bulb light.

The oven must have been heating for at least
half an hour before you use the steam system. If
not, water will appear at the bottom of the oven.

Check if the water supply valve (of the
building) is open.
Check if the water needle valve (of the oven) is
open one eighth of a turn. Just close it and open
it one eighth of a turn maximum.
Check the solenoid valve.
Check the preset steam timer in the back
control box.
Be sure to inject steam while the fan is running.
The steam button light should lite during the
steam injection.
