Door Switch Start Your Repair Here

- Takes less than 15 mins
We have 13 installation instructionsThere are many reasons your microwave won't turn on, one of which might be a faulty door switch. The door switch, also known as an interlock switch, signals other microwave components to begin powering when the door is closed, and to stop when the door opens. For this reason, everything else may appear in working order but the microwave will not begin heating. To access the door switch or interlock switch, unplug the microwave and dismantle the cabinet. The switches have terminals which are marked C for common and NO for normally open. Check each terminal with a multi-meter for continuity. If there is continuity while the actuator button is engaged, that means the switch is working. If there is no continuity, replace the switch. You can also take this opportunity to make sure the door hooks are working properly.
Ceramic Fuse Start Your Repair Here

We have 1 installation instructionIf your microwave won't start and the display is blank and unresponsive, the issue may be with the ceramic fuse. This part protects other microwave components from power fluctuations, and causes a complete loss of power when it fails, meaning your microwave won't work. To access the ceramic fuse, located inside the cabinet near the power cord, first unplug your microwave. Use a multi-meter to test the continuity of the fuse. If you are aware of the cause of the fuse failure, such as opening or closing the microwave door, you can also test the door switch to see if that is working. If you are unaware of the reason for the fuse failure, you may want to test other microwave parts such as the magnetron, high voltage diode, capacitor, and transformer.
Thermal Fuse or Cut Out Start Your Repair Here

- Takes less than 15 minsA problem with the thermal fuse or cut out could be the reason your microwave won't turn on. The thermal cut-outs, also known as thermal fuses, help keep the oven from overheating. When the thermal cut-outs fail, your microwave won't turn on as a safety precaution to keep it from getting too hot. To access the thermal cut-outs, first unplug your microwave and then remove the cabinet. Once you locate the thermal fuse, disconnect its wires from the terminals. Use a multi-meter to test for continuity, and replace the thermal cut-outs if there is no continuity. Take this opportunity to also check that the cooling fan is working and not causing the microwave to overheat by cutting off airflow.
Door Latch Assembly Start Your Repair Here

We have 4 installation instructionsYour microwave may not start because of an issue with the door latch assembly. Most door latch assemblies are made of plastic hooks that stick out of the door and engage the door switch when the door is closed, signalling the rest of the controls to power the microwave. If the hooks are damaged or lacking tension due to worn-out springs, the switch will not latch properly meaning the microwave won't turn on. To access the door latch, first disconnect the microwave from its power source, and remove the inside door panel, which is held in place with plastic tangs. Inspect the door latch and replace it if it appears to be damaged.

Hello Terrell,

If "wont come on at all" means no light when door is open, no clock, nothing, then assume complete loss of power to that circuit.
These are often powered by an isolated circuit with its own breaker. The first place to look is your power distribution panel and see if you can find a tripped breaker.
If yes, then reset the breaker and see if the microwave has lights, clock, etc.
If no breakers are tripped, the actual microwave plug is often in a cabinet above the microwave. Sometimes, these may get pulled out while moving items in and out of the cabinet, so check that too.
If unsuccessful, microwaves also include an internal line and/or thermal fuse which fail due to overloading. Also, the control panel can go bad or become unplugged from slamming the door, etc.
If you do have lights, clock etc., then a faulty door latch will prevent operation of the microwave generator.

Unfortunately, will need additional information to properly identify the potential.
I hope this helps.

Hello and welcome new user of fixya! I found a link to the bosch support page: Bosch Home Appliances Customer Service Support Repair Parts. Try giving them a call or a shooting them an email. Best of luck!

If this is a built in mounted under an overhead cabinet, Just open the above cabinets and there will be 2 long screws facing downward that hold it in place, if it is a built in that is framed in then you will need to remove the frame and the brackets behind the frame that are holding it in place and then slide it out.

You are going to have to replace the door switch. The switch is staying open even when it should be closed. Talking about electrical current. Once that part is replaced everything will work just fine.

Hello,On the front of the microwave above the door is a louvered panel. You need to remove the panel ( usually it just pulls straight off ) and inside on the left you will see a metal rod that's bent 90 degrees. That is the lock handle. While lifting on the front of the microwave pull that handle out to release the lock. The front of the microwave will tilt down, you may have to help it start tipping. Once the microwave is tipped down you have to lift the back that is against the wall to unhook it from the wall mounting panel. Be careful to feed the power cord through the cabinet hole as your lowering it. Good luck and let me know how this works.

You did not note your Make and Model. As there are many different types, all I can give you are basic directions.
First make sure the Power Cord is UN-PLUGGED from the wall.

1. Remove the Top Vent Grille Cover. There are screws holding this on, either Three you can see (one on each side and one in the center), or Open the Door and look for screws at the top of the Frame that go Up Into the grille.
2. Look in cabinet above unit for screws that hold unit up. Usually two (one on each side, front), can be more. Remove.
3. Look where Top Vent Grille Cover was removed. There should be a Long Screw or Screw-Type Lock at each( top) corner. These hold the unit tight on the Wall-Mount Plate. Remove. You should have HELP at this point as you will slide the unit forward until it comes clear of the Support Arms.
GOOD LUCK!!
