OVEN DOOR LATCH SERVICE KIT 751505
Due to a supplier change, the oven door latch now offered as the service replacement for some Bosch, Thermador, and Siemens built-in wall
ovens may have a slightly different design than the original part. Service kit 751505 has been developed to make the new latch compatible with
products originally built with the 644216 Meteor latch. For wall ovens built with the newer HTI latch, the HTI latch in the service kit can be used
as a direct replacement.
This bulletin includes instructions for unlocking a stuck latch and for replacing a latch with some or all components in Latch Service Kit 751505.

PENING A STUCK LATCH
If the
oven door latch being serviced is stuck in the locked position, first try to cycle the latch by resetting the power. If that fails, run a thin
wire or a wire coat hanger in between the door and the front face of the oven. Position the wire between the latc
h hook (1) and the plunger
(2), then slide the wire to the left, pushing the latch hook left
and releasing the latch.
