heats up, and a current sensitive oven safety valve that
needs a minimum of 3.2 amps of current to open. When
electrical power is first applied to the circuit the resistance
of the igniter is high enough that the current flow in the
circuit is below the amount needed to open the safety
valve. As electrical current flows through the igniter it
causes the silicon carbide material to heat reducing the
resistance of the igniter and increasing the current flow
in the circuit. When the temperature of the igniter
reaches around 1800 degrees F the current flow in the
circuit exceeds 3.2 amps. The bake section of the safety
valve opens allowing gas to flow into the bake burner. The
gas is then ignited by the heat of the bake igniter and the
oven begins to heat up.
In the tip of the oven sensor is a positive coefficient
thermistor that increases in resistance as the oven
temperature increases. The microprocessor reads the
resistance of the oven sensor, and compares it with a
programmed temperature set into the control. When the
resistance of the oven sensor indicates temperature in
the oven is about 10 degrees above the programmed
temperature the microprocessor opens the relay, which
removes power from the bake circuit and closes the
safety valve. When power is removed from the bake
circuit the oven temperature begins to lower. As the
oven temperature lowers the resistance of the oven
sensor decreases. When the oven drops to about 10
degrees below the programmed temperature the
resistance of the sensor tells the microprocessor to
close the relay contacts, and provide power to the bake
circuit. After the first cycle the "Pre" will disappear in the
display indicating the oven is preheated.
Note: Oven controls may have a spread of more
or less than 20 degrees.
thing is the average temperature in the
oven. The average temperature in the
center of the oven should be within 10
degrees of the programmed temperature.

BAKE

When the Bake pad is touched, and a temperature is
programmed with the number pads, the bake relay on the
board closes, applying line to neutral voltage across the
bake circuit and "Bake" will appear in the display. The
bake circuit is a series circuit made up of the electronic
oven control, a silicon carbide igniter that reduces in
resistance as it heats up, and a current sensitive oven
safety valve that needs a minimum of 3.2 amps of current
to open. When electrical power is first applied to the
circuit the resistance of the igniter is high enough that the
current flow in the circuit is below the amount needed to
open the safety valve. As electrical current flows through
the igniter it causes the silicon carbide material to heat
reducing the resistance of the igniter and increasing the
current flow in the circuit. When the temperature of the
igniter reaches around 1800 degrees F the current flow
in the circuit exceeds 3.2 amps. The bake section of the
safety valve opens allowing gas to flow into the bake
burner. The gas is then ignited by the heat of the bake
igniter and the oven begins to heat up

TIME BAKE

The time bake function allows the oven to be programmed
to stop bake at a set time, or to delay the start and stop
baking at a set time. The stop time cannot be set for
more than 11 hours and 59 minutes ahead of the time
of day.

CONVECTION BAKE

The important
When the convection bake pad is touched and a
temperature is set two things happen that do not
happen in normal bake. The electronic oven control
automatically raises the temperature 15 degrees and
after five minutes, the control turns the fan and the assist
element on. The delay is needed for the oven flame to
have proper venting stack action. After five minutes, and
if the oven door is closed, the convection relay on the
electronic oven control closes providing line to neutral
voltage to the convection fan motor and the convection
assist element. This relay remains closed until the
program is canceled or is interrupted by the opening of
the oven door. If interrupted by the opening of the oven
door, the relay will automatically close when the door is
closed.

CONVECTION ROAST

Convection roast operates the same as convection
bake except the control does not operate above the set
