Lockout

Once the gas has ignited, the “flame safety circuit” will monitor the flame at the burner to make sure it is present. If a flame is not present at the burner:

a)The control will allow the ignitor to spark for 4 seconds.

b)A 40 second delay to dissipate any un- used gas inside the oven will occur.

The ignition attempt will occur three times. If the burner does not ignite after the three at- tempts, the system will “lockout” (see the Tim- ing Chart below).

Lockout

The control will perform an oven system lock- out if:

a)Any of the self-test checks fail.

b)The oven fails to ignite after three igni- tion attempts.

c) A flame is present within the oven for more than 10 seconds after the gas valve is off.

d)The flame is unexpectedly lost for any reason after being established. NOTE: If this occurs, a lockout condition will oc- cur after 30 seconds with no attempt to reignite.

During the lockout, the gas distribution valve and ignition are turned off. All lockouts can be reset by pressing the OFF/Cancel keypad on the Electronic Oven Control. NOTE: There will be no indication on the electronic oven control display showing a lockout condition.

Note To Technician: The cooktop spark op- erates normally even when the oven is in the “lockout” mode. If the oven does not appear to work at all, verify the operation of the cooktop spark. If the cooktop spark is working correctly, the DSI control is most likely okay, and the problem is somewhere else in the range.
