2.Power switch (S1) turned to COOL DOWN.
A.Power to fan speed switch (S3). Set fan speed switch to either HI or LO.
3.If door is closed, power is supplied to one side of the following components:
A.Power ON light (Amber) comes ON.
B.Transformer (T1) energized.
1)Power (24 VAC) to one side of the following components: heat relay (R3) normally open (N.O.) contacts, high limit connected through the normally closed (N.C.) contacts to the first valve (safety) on the dual solenoid gas valve.
a.First valve (safety) on the gas valve energized. Gas does not flow to the burner until the second valve (main) is energized.
C.Component cooling fan.
D.Power to timer and oven cavity lights.
4.The oven will remain in this condition until the master switch (S1) is turned to the OFF or ON position.
