WARNING
Momentary Door Latch Switch
The momentary door latch switch is mounted to the
door latch. It is identified by the roller attached to the
actuating arm. The momentary switch contacts close
momentarily when the door latch lever is being moved
in either direction. When switch contacts close, power
is applied to the door lock solenoid. The solenoid pulls
the door lock stop lever back and out of the lock arm's
travel path. During self-clean operation when the oven
temperature exceeds approximately 650 to 700 de-
grees F, the thermostat contacts C-NO open and C-
NC close interrupting power to the momentary switch.
The oven door is locked and cannot be opened with
power removed from the momentary switch. When the
oven temperature drops below approximately 650 -
700 degrees, thermostat contacts C-NO close and C-
NC open, apply power to the switch and allow the door
to open.
Use the following procedure to check the momentary
switch contacts for continuity.
Upper Momentary Switch
1. Disconnect power from range. Disconnect switch
wiring.
2. Access upper switch by removing control panel
glass and control panel mounting bracket.
3. Set ohmmeter in the low ohm range. Attach meter
leads to switch terminals.
4. Meter should indicate no continuity or infinite ohms
when latch lever is in opened or locked position.
5. Move latch lever to center position to close switch
contacts. Meter should indicate continuity or a low
ohm reading.
Lower Momentary Switch
1. Disconnect power from range. Turn thermostat to
OFF.
2. Set ohmmeter in the low ohm range.
3. Attach one meter lead to the N.O. terminal on
lower oven thermostat. Attach other lead to a white
wire on neutral terminal block.
4. Meter should indicate no continuity or infinite ohms
when latch lever is in opened position.
5. Move latch lever to center position to close switch
contacts. Meter should indicate continuity or a low
ohm reading.
If the lower switch test indicates an open circuit, test
both the momentary switch and door lock solenoid to
determine which part is defective. If both parts must be
individually checked, refer to the momentary switch
and solenoid removal procedures to access these
parts.

Door Latch Solenoid
Use the following procedures to test upper and lower
door latch solenoids.
Upper Door Latch Solenoid
Access the upper solenoid by removing the control
panel glass and control panel mounting bracket.
1. Disconnect power from oven.
2. Remove solenoid wire.
3. Set ohmmeter in the low ohm range.
4. Attach meter leads to solenoid terminals.
5. Meter should indicate continuity or low ohms. If
meter indicates infinite ohms or no continuity, the
solenoid coil is open. Replace solenoid.
6. Remove one lead and touch the outer metal cas-
ing. Infinite ohms or no continuity should be indi-
cated. If a low ohms reading or continuity is indi-
cated, the coil is shorted to the casing. Replace
solenoid.
Lower Latch Solenoid
Test the lower solenoid by following the lower momen-
tary switch test procedure described earlier.
Top and Rear Latch Switches
The top and rear door latch switches are mounted to
the door lock and are used in self-clean operation.
The rear latch switch is mounted to the door lock be-
hind the momentary and top latch switches. The top
latch switch is mounted on top of the momentary
switch. The top and rear latch switch contacts close
when the latch lever is moved to the far right or lock
position. The rear latch switch completes the clean cir-
cuit through the sail switches, selector switch, thermo-
stat, clean relay, broil ignitor broil gas valve to neutral
when self-clean temperatures are below approxi-
mately 650-700 degrees F. At temperatures above ap-
proximately 650-700 degrees F., the top latch switch
completes the self-clean circuit through the sail
switches, selector switch, thermostat, clean relay,
bake ignitor and bake gas valve to neutral. If a no self-
clean condition exists, one of the latch switches may
be defective.
Access the upper oven latch switches by removing the
control panel glass and control panel mounting
bracket. Use the following procedure to check for con-
tinuity.
1. Disconnect power from oven.
2. Set ohmmeter to low ohm range.
3. Remove wiring from both switches. Attach meter
leads to switch terminals.
