Does a fan run continuously in Bake mode?

When we start the oven in Bake mode a fan appears to run. At temperature the sound does not change. The convection fan in the back of the oven does not appear to be moving. We have a Studio wall oven LSWS305ST.
Asked by: KenPA
We appreciate your interest in this Studio Series Wall Oven. This device is designed with more than one fan in the system. The Convection Fan will not be running during the standard bake function. Another fan can still be in operation. It seems this unit is operating normally.

Does the Studio series wall oven blow hot air out the front when baking?

Many single wall ovens on the market today blow a lot of hot air out the front when they operate. Is this the case with the LG studio series single 30" wall oven? Also, will the broiler operate with the door open a bit?

cleaning the oven

can you keep the racks in during cleaning
Asked by: Anonymous
It is not recommended to leave the racks in the oven during the self-cleaning cycle. On page 30 of the owner’s manual, this is stated at least twice: Remove the oven racks, broiler pan, broiler grid, all cookware, and aluminum foil or any other material from the oven.
