Sample Model Number Tags
Model numbers can be made up of numbers (1005400, for example) or a combination of letters and numbers (LAT1000AAE). The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):
This microwave microswitch functions as a door interlock safety component, preventing the appliance from operating when the door is open. It ensures safe and efficient performance by interrupting power to the microwave when the door is not securely closed. Built for durability, this part is essential for maintaining proper safety standards. If your microwave fails to start or operates incorrectly, a faulty door switch may be the cause. Installation requires disconnecting the appliance from power before replacing the switch.

No heat and turn table did not turn
After going to a local parts store to get the correct switch, I replaced the right door switch. The correct switch is a normally open switch. The one shipped to me was a normally closed switch. Either Bosch provided the wrong description of the part required or someone at partselect needs to check the part stocked.

20A Fuse burns every few days
I replaced the microswitches on both sides of the oven door. The procedure is very easy: - Unplug from power - Remove the top cover - there are two parts (screws are on the top) - Remove the support on the right side (the microswitch is inside this part) - by removing the two screws screws on top of the part. - Remove
... Read more the two electrical wires from the switch by pulling the cable shoes. Note that the cable shoes can be snug - don't pull on the wires. - Insert the microswitch (the one with red micro button) into the new support - in an identical position. Use the old part as a reference. Note that there is a tiny latch inside that should be moved gently aside to allow the switch to get in place. - Connect the electrical wires and install the new support in place. -Repeat the procedure on the left side - note the left side has two switches - one with green micro button and the bottom one identical to the one on the right. - Make sure to install a new fuse before closing the top covers.
Microwave/Combo Oven trips breaker when you open the door
There are two small switches that the door interacts with. As they age they can fail outright or "stick" --either will trip your breaker. It is also likely that the small plastic support holding the switches starts to age and allow play or movement of the switches. I replaced both switches (after testing that one of them was bad) and b
... Read moreoth supports. About $35 to keep a 6 year old microwave going. Way better than replacing it for $1750+. It takes help to remove/replace the oven from the wall, but only a screwdriver to remove the side and top pieces to access the switches and supports YouTube videos can guide you. Thanks partselect.com for keeping me going with your Bosch parts selection!
The breaker in my house would stay open on microwave circuit
I watched a YouTube video that confirmed the diagnosis of failed safety switch. Order the switch and the housing as recommended (because the housing is cheap plastic and as it ages it wiggles too much and no longer holds the switch correctly). With help of my sons to get the microwave out this was an easy repair. I recommend taking
... Read more the left side panel off (involves removing the left frame rail as well, but makes access SO much easier). Bottom line: no need to replace a $1700 microwave. No need to replace several appliances to go with a new brand (that was wife's idea for $4500!). Nope! $15 of parts from partselect.com (plus shipping) and we are cooking again! THANKS!

This is microwave/oven combination attached to an oven with the same power source. The oven works fine, but the microwave/oven combo is not receiving power.
