5.   Wait until the Heat On indicator has come on and gone out three times. At that time the oven will have 

reached the set cooking temperature. 

 

6.    Open the oven doors, load the product into the oven, and close the doors. 

 

7.    You can use the Cook Timer as a reminder of when the remove the load from the oven. If so desired, turn 

the Cook Timer knob until the indicator mark points to the desired cooking time (up to 55 minutes). The 
timer knob will rotate counterclockwise as the timer runs down, indicating how much time remains. You 
can turn the knob while cooking to increase or decrease the remaining time. When the timer runs out, a 
buzzer will sound for a short time, then turn itself off. (To immediately silence the buzzer, turn the Cook 
Timer knob to the OFF position.) The timer is a reminder to you; 

the timer does not control the oven.

 

If  you open the oven  doors, the burners and fan will shut off until the doors are  closed. However, the timer 
will continue running even if the doors are open. 

To  turn  on  the  interior oven lights,use the   switch located at the bottom of the control panel. 

8.    When  the load  has  finished  cooking,  you  can rapidly  cool  the  load  by  opening the  oven  doors  (which 

will shut off the burners) and switching the Fan Mode to COOL (which will cause the fan to run even 
though the doors are open). For the most rapid cooling, also switch the Fan Speed switch to HI. 

 

9.  When you are done cooking, turn the Cook Temperature control to the lowest setting (fully 

counterclockwise) and switch the Power Switch to OFF.

OOKING 

H

INTS 

 

In a convection oven, the fan-blown circulating air strips away this insulating layer allowing the heat to 
penetrate faster for quicker baking and roasting. Hence, in a convection oven cooking procedures and 
techniques may require some modification for successful results. As a general rule, the cooking time will 
be shorter and the cooking temperature will be 25°F to 75°F lower than those called for in recipes for a 
standard oven. 

 

 

TIME & TEMPERATURE 

 

Time and temperature are important. The 

“Guide to Times and Temperatures” later in this section is a 

starting  point.  The  actual  best  cooking  time  and  temperature  will  depend  on  such  factors  as  size  of  load 
and mixture of recipe (particularly moisture). Once an appropriate time and temperature has been 
established for a particular product and load, you will find the result of succeeding loads to be similar. 

 

 

OVERLOADING 

 

Do NOT overload the oven. The size of the load that can be cooked satisfactorily depends largely on the 
particular product. As a rule, five racks can be successfully used for shallow cakes, cookies, pies, etc. For 
deeper cakes (such as angel food), use only three racks because of the size of the pan and the space 
required for rising. For hamburger patties, fish sticks, cheese sandwiches, etc., a full complement of racks 
and pans is usually satisfactory. 

 

 
HELPFUL SUGGESTIONS 

 

Here  are  some  suggestions  that  will  assist  in  getting  the  best  possible  performance  from  a  convection 
oven: 

 

• 

Pre-heat the oven thoroughly before use. 

 

• 

When  re-thermalizing  frozen  products,  pre-heat  the  oven  to  50°F  higher  than  the  planned  cooking 
temperature. After loading, reduce the temperature setting to the appropriate cooking temperature. 

 

• 

Space the racks and pans as evenly as possible to allow air circulation. 

 

• 

Center the load on the racks to allow for proper air circulation around the sides. Do not cover the racks 
completely with pans. 

 

• 

Do  not  use  a  deep  pan  for  shallow  cakes  or  cookies,  etc.  Air  circulation  across  the  surface  of  the 
product is essential.
