NOTE: The Self-Clean cycle is a continuation of the Self-Clean Preheat cycle.
Press the SELF-CLEAN keypad and the following events will occur on the relay board:
• The L1 Relay connects L1 line voltage to the Bake and Broil Elements.
• Bake Relay K1 and Broil Relay K2 close and connect the L2 (120-volt) line to the Bake and Broil
elements. NOTE: The Broil Element is on for 44-seconds, and draws 15-amperes during each 1-
minute cycle. The Bake Element is on for 15-seconds, and draws 11-amperes during each 1-minute
cycle.
• After Self-Clean Preheat, Relay K2 cycles off, via the thermostat. When the thermostat cycles back
on, (to maintain the 850˚F self-clean temperature), Relays K1 and K2 are alternately used to maintain
the self-clean temperature until its time has expired, at which point, the oven turns off.
