Customer Questions and Answers for Mechanical Latch Lock Assembly by Bosch

Winfred, We would need the actual model number to look up the wiring diagram. Please post another question with all your info included thank you.

Rafael, aside from doing a voltage test at the latch motor to ensure it is receiving proper voltage, the latch can be observed for rotation. If the motor rotates and moves the latch, then it is possible that the switches are not operating properly. The switches can be tested for continuity (with the power turned off from the entire unit). With the switches being activated at the plunger, the terminals on each switch should have continuity. If the motor is receiving voltage but not moving the latch, or any of the switches fail for continuity, then the lock assembly has failed.

Steve, you may want to inspect the latch lock assembly to ensure that it is fully in the unlocked position and is not catching on the door lock insert. If it is, then the proper correction would be to replace the lock assembly. Another thing to check for would be any small obstructions that could be getting caught in between the door and cabin.

Harry, The Electric lock 00489102 is showing as being the only lock on this unit but shows for the oven door and not the microwave and does not show a latch for the microwave.

Carmine, Unfortunately the mechanical latch lock 74004528 has been permanently discontinued with no suitable replacement available.

Chuck, Unfortunately we do not have instructions on this but will need to lift the main top from the unit to be able to access the motor for the latch assembly.

Chris, Yes the mechanical latch lock assembly 00489102 will work for your unit.

Dan, You would want to try and get between the door with a rigid wire with a hook and slide it over and hook the latch to pull it over to get the door open.

Battlin, Unfortunately there is no information on this door lock being wired differently. Unfortunately we would not be able to assist as we do not have wiring information on this unit.

Hello Patrick. These are not to hard to replace and yes, according to your model number, 00489102 is the correct door lock for the unit. Just make sure you wire it up like the old one was wired in the unit.
