Control Component Test Procedure Results
EOC II Oven temperature
adjustment Press Bake pad and enter 550° F (288° C). Press
and hold Bake pad until TEMP ADJ displays.
Press Autoset pad to adjust oven in 5° F (-15° C)
increments, from -35° F (-37° C) to 35° F (2° C).
While increasing or decreasing oven
temperature, this does not affect self-
cleaning temperature.
