DOOR LOCK
Function: When the Door Lock Motor is
powered it turned a cam which pulls back a
lever. As the lever moves back it allows a
micro switch (SW1) to open. When the lever
reaches the fully closed position it closes a
double stacked micro switch (SW2 & SW3).
Door lock switch SW2 completes the circuit
to sensor #3 on the Door Lock Control/timer
board. After 10 seconds LS1-M1 opens,
stopping the Door Lock motion. Door Lock
Switch #3 closes T1-T2 and T3-T4 energizing
Power Relay #1 and the Cooling Fan. Closing
Power Relay contacts supplies 240 VAC to
both Broil Elements and 120 VAC to the
Bake Element.
POWER RELAY #1
Function: Relay #1 ( power ) supplies power
to the Bake and Broil Elements.
RELAY #2 and RELAY #3
Function: Setting the selector switch to clean
closes the Heating Element circuits 4-F, 1-N,
2-L2, 3-L2 and Door Lock Module / Timer
circuit J-6, energizing Relay #2.The
thermostat cycling contacts 1 to 2 and the
clean switch contacts 3 to 4 close energizing
Relay #3. Relay #3 allows circuit J-6 to turn
on the Clean Indicator Light and enable the
Door Lock Module / Timer to close Relays
LS1-L1 and LS2 - M1. This powers the Door
Lock Motor until 10 seconds after Sensor 3 is
signaled by VC that Door Lock Switch SW2
has been closed mechanically (along with
SW3) by the Door Lock Bolt.
