Self Clean Latch Mechanism
Step 1: Disconnect power supply to
range. Pull range away from wall
and remove backguard held by 3
screws and washers. See Proce-
dure A Step 1.
Step 2: Prop Top Up. See Proce-
dure P.
Step 3: If self clean results are
poor, check all switches, wiring and
connections to self clean
microswitch.
Note: Black microswitch allows
signal from latch to confirm timer
that oven door is locked - this
allows self clean cycle to begin. If
latch is stuck or switch is
disconnected or faulty, self clean
will not commence.
Step 4: Test switch with multimeter
for continuity - switch is normally
open, close switch and test.
Step 5: To replace switch, with a
slot screwdriver push on the two
clips and pull the switch upwards
Replace black wires on new switch
in same two left positions, right
position is empty.
Step 6: Check microswitch to
cooling fan - top white switch.
Chech to ensure wiring is making
good contact to the two outer
positions (center position remains
empty). If incorrectly wired, unit will
not self clean properly since cooling
fan will not engage during self clean
and safety temperature limit in timer
will shut down operation.
Step 7: Test microswitch for
continuity when button is depressed
across terminals 1 and 2 by placing
test probes on terminals. If no
continuity in the on position, replace
switch.
Step 8: To replacem unscrew
microswitch from support place and
transfer red wires from old switch.
Step 9: If all switches and wiringto
switches test in good order, latch is
not operational, Disconnect all
wires from micro switches, one at
the time and place on new latch
assembly.
Step 10: With short Phillips
screwdriver remove four screws
holding assembly to top of stove
Push both clips
away from
switch to release
Step 11: Replace with new
assembly
Step 12: Latch Replacement (latch
warped or bent): Remove two
Phillips screws holding latch in
place and replace with new latch.
Note:
Do not over tighten screws
as they must allow movement of
the latch back and forth.
Self Clean Operation:
During self clean, door automati-
cally locks (wax motor energized
and pushes latch to lock) and
cooling fan starts. temperatures
cycle off the timer.
When door locks, “black”
microswitch closes, sends signal to
timer to confirm door locked - unit
will begin self clean cycle.
If latch is stuck and door does not
lock, self clean program will shut
down.
If any of the 2 microswitches on the
self clean assembly malfunction,
unit will not self clean properly.
