Special Tips
l
Keep the kitchen well aired during the cleaning cycle to help get rid of
normal
heat odors and smoke.
l
Clean the upper oven before it gets heavily soiled. Cleaning a very soiled
oven takes longer and results in more smoke than usual.
l
If the cleaning cycle doesn't get the upper oven as clean as you expected, the
cycle time may have been too short or you may not have prepared the oven
properly. Set the cleaning time longer the next time and hand clean areas
noted on page 18.
l
Oven
racks lose their shine, discolor and become harder to slide when they
are left in the oven during the cleaning cycle. To make them slide easier, polish
the edges of the racks and rack guides with a soapy steel-wool pad, rinse well,
and wipe on a thin coat of salad oil.
How It Works
During the self-cleaning cycle, the oven gets much hotter than it does for baking
I
or broiling...approximately 875°F (468°C). This heat breaks up grease and soil ant
burns it off.
The graph shows approximate temperatures and times during a self-cleaning
cycle for 3 hours.

Notice that the heating stops when the 3-hour setting is up, but that it takes longer
for the oven to cool down enough to unlock.
