Controls power to door motor(s).
Controls power to cavity vent motor.
Controls power to component cooling fan(s) and supplies power to one side of K4, K5, and K6, K7, K8, K9 and K10 through the thermal fuses and high limit thermostats.
Controls power to water injection solenoid valve (humidifier) and door light when K3 is ON.
Controls power to water fill solenoid valve (when K3 is ON) and drain pump motor (when K3 is OFF).
Controls power to contactor KM1. This relay is energized along with K7 for full power full speed operation, and is also energized in half power speed half mode. When half power half speed mode is selected, relay K6 is energized.
Controls power to contactor KM2. This relay is energized along with K6 for full power full speed operation. When half power half speed mode is selected, relay K7 is not energized. On 20 level models only, controls power to contactor KM3 for steam generator heating elements, and powers 2SOL drain cool down solenoid.
Controls power to KM3 for steam generator heating elements, and powers 2SOL drain cool down solenoid valve on 6 & 10 levels. On 20 level models only, controls power to contactor KM5.
Controls power to KM6 for convection heating elements; (1HTR) single on 6 level ;(1HTR) inner on 10 level; (1HTR) inner top and (5HTR) inner bottom on 20 level.
Controls power to KM7 for convection heating elements ; (3HTR) outer on 10 level; (3HTR) outer top and (6HTR) outer bottom on 20 level.
