hi this is Wayne sears PartsDirect today
we're going to talk about an oven with a
malfunctioning door lock you're probably
watching this because your oven door
stuck shut
let me guess did you just run a
self-cleaning cycle during the cleaning
cycle you're adorable lock for safety
purposes under normal circumstances the
door won't unlock until the oven is cool
to room temperature the thing is if you
lose or disconnect power before the
cycle is finished the lock motor may not
complete the cycle to unlock the door
we'll show you how to reset the lock and
get things working but the lock motor
itself could be broken so we'll also
show you how to test that out while
you're back there now that it's stuck
shut I'm going to show you how to get it
open fast and get back to cooking pull
the range out from the wall and
disconnect the power remove the back
panel to gain access to the lock motor
assembly remove the screws holding the
door lock assembly in place release the
door latching rod by pulling the lock
motor assembly down and tilt the front
inwards this will allow you to unhook
the locking rod from the Drive cam push
the rod forward and open the oven door
note the position of the drive cam and
the hole that the locking rod fits in to
remove the Phillips screw holding the
drive cam on the motor
remove the drive cam and rotate it 180
degrees from where it was when the door
was locked
line up the two slots on the bottom of
the drive cam with the post on the motor
shaft push the drive cam down and lock
it on the motor shaft make sure that the
switch arm aligns with the side edge of
the Drive cam
reinstall the Phillips screw on the cam
rehook the locking rod back onto the
Drive cam install the motor bracket
assembly back onto the range now you can
put everything back together and at
least to be able to cook again but if
you got a bad door lock your doors gonna
get stuck again the next time you run a
cleaning cycle we'll check the lock
motor circuit for electrical continuity
with a multimeter while we've got this
back panel off always disconnect power
before checking continuity locate the
two electrical wires going to the lock
motor and disconnect them set your meter
to read ohms of resistance on the 20,000
ohms scale place one meter lead on each
terminal of the lock motor if you
measure no continuity
on this meter that's a one on the far
left corner then the door lock is bad
and will need to be replaced here's a
video that will show you how to do that
if the lock motor reads about 2000 ohms
on the multimeter then the motor is good
let's see if there's a break in the wire
harness next plug the wires back into
the lock motor remove the upper back
panel locate the two wires from the
motor that are connected to the
electronic control board that's the
brown and white wires on this model
disconnect the wires from the electronic
control board and put one meter lead on
each wire if your meter shows no
continuity then you'll need to repair
the broken wire in the harness here's a
video about repairing broken wiring if
you get a reading of about 2,000 ohms in
both the harness and the door lock or
okay that tells you the electronic
control board is failing to send current
to the lock motor you'll need to replace
the control board here's a video showing
you how hey thanks for watching I hope
