CONVECTION ELECTRONIC OVEN CONTROL

The convection oven uses the addition of a fan to move the heated 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 is circulated around the food and then enters the
shroud again. As with conventional electric ranges, there is still an oven
vent which discharges through the top at the control panel.

 

 CONVECTION MODE

In models containing a convection oven, the electronic oven control is mounted as follows:

1. There is no Preheat pad on this control. The pad in the upper left hand corner has now become

the CONV. BAKE/ROAST pad.

2. A relay is mounted beside the control which operates the convection fan in some models.
3. Another relay is mounted beside the control, which operates the oven lamp.
4. There are only two fault codes.
5. Electronic oven controls that have a PREHEAT pad instead of a CONV. BAKE/ROAST pad, do not

require an additional external relay for the PREHEAT function.

The convection EOC's are not field repairable. Only temperature settings can be changed. See
"Oven Calibration".

This relay operates the
oven lamp.

On convection models, an
additional relay is mounted
outside the control to
operate the convection fan.

CONV. BAKE/ROAST is
replaced by PREHEAT on
some models

Depending on
model,  the size
and shape of
button pads may
vary.
