1. This self-cleaning controller offers Bake, Broil, Preheat or Convection Baking/Roasting modes, Timed and
Delayed Baking and Cleaning functions.
2. Convection operates with a fan dedicated to convection and a convection element on some models.
NOTE: THE ERC III'S ARE NOT FIELD REPAIRABLE. ONLY TEMPERATURE SETTINGS CAN BE CHANGED.
See Oven Calibration.
NOTE: Depending on model, the size and shape of touch pads may vary. (For example, eliptical instead of
round). Some models may also have round push buttons instead of touch pads.
Because heat is more evenly distributed in convection mode, foods can be cooked at lower temperatures. In order
to allow the consumer to bake per their existing methods, there is a negative offset temperature of 25°F/13.5°C in
the programming of the control. This means that when the consumer sets the control for 375°F/ 190°C , the actual
oven temperature is cycling at 350°F/ 176°C.
The convection oven uses the addition of a fan and a convection element (some models) to heat and to move the
air already in the oven. Moving the heated air helps to destratify the heat and cause uniform heat distribution.
Cooking times can be reduced by as much as 30%. The air is drawn in through a fan shroud located on the rear
wall of the oven. It is then discharged around the outer edges of this shroud. The air circulates around the food
and then enters the shroud again. As with conventional electric ranges, there is still an oven vent which discharges
through the rear or the sides of the cooktop.
To set the control in convection mode, follow these steps:
1. Press the CONV. BAKE/ROAST pad.
2. Enter the desired temperature on the keypad (setpoint).
3. Press the START pad.
The oven will automatically start and the fan will begin to run. To cancel the convection baking/roasting function,
press the CANCEL pad.
NOTE: The fan runs continuously while in the convection mode. The fan will stop if the door is opened while
convection baking/roasting. The heating element will continue to operate IF the door IS openED.

When the control is set to the convection bake/roast function, the fan immediately comes on. The oven then
energizes the convection element for 5 to 15 seconds and switches to the bake element. This switching continues
until the oven setpoint is reached. At this point the control modifies the timing for the bake and convection
elements to achieve maximum performance.
For the first 15 to 30 seconds of every minute after the setpoint is reached, the convection element is energized.
For a few seconds both elements are turned off. The bake element is then turned on for the remaining time of the
minute. This cycle is repeated for the duration of the cooking period.

Set EOC for conventional bake at 350oF/177oC. Using a portable thermocouple, obtain an average oven tempera-
ture after a minimum of 5 cycles. Press CANCEL to end bake mode. Touch the BAKE pad. Set temperature to
maximum (550oF/288oC). Quickly (within two seconds), press and hold the BAKE pad until the special two digit
display appears. Release the BAKE pad.
NOTE: The display indicates the offset temperature from original factory setting. Original setting will read "00".
The temperature can now be adjusted up or down 35oF/21oC, in 5oF/3oC increments, by pressing the up or down
arrow pad. Press the pad until the desired amount of offset appears in the display. A minus sign (-) will appear
before the number to indicate the oven will be cooler by the displayed number of degrees.
NOTE: Changing calibration effects both conventional and convection modes.
PREHEAT (some models)
During a preheat mode, the oven uses the bake element to reach the ERCIII set point. The element uses full
power when it's on. When the set point is reached, the preheat mode is converted in a normal bake mode.
During a normal bake mode, the ERC III preheats the oven with the bake element. When the desired
temperature is reached, the ERC III adds top heat by cycling the broil element on for 5 to 15 seconds per minute .
The bake element is on for the remaining time of the minute. Both elements use full power when they are on but
they are never on at the same time.

The fan motor on the rear of the unit is mounted to the main back with three screws. There is a mounting plate
held in place between the main back (with 2 screws) and the rear oven wall (with 2 screws). Should it be
necessary to replace the oven cavity, you must remove the 2 screws located inside the unit at the rear of the oven
cavity.
The fan motor runs continuously while in the convection mode unless the door is opened. If the fan does not operate,
check the following:
• Display illuminated on the electronic control.
• Voltage output between terminals E9 and E8.
• 240 Volts available at fan motor.
• Fan motor coil resistance 56.5 ohms ± 10%.
• Voltage input to fan relay coil during convection bake with door closed.
• Door/light switch.

This appliance is equipped with an electronic oven control and has an auto locking door latch feature. When the
self clean cycle is programmed, the door is locked by a motor operated latch system. The interior of oven does not
need to heat up to 600°F before the door locks. However, until the temperature inside oven reaches 600°F, the
self-clean program can be canceled and door will unlock immediately. After oven reaches temperatures over
600°F, the door will not unlock until temperature falls below 600°F.
