Why is door not closing properly?

It sounds like you are having difficulty with the bottom switch on your Samsung Model GE0103MB microwave not engaging with the door release button. This can prevent the microwave from functioning properly and could be caused by a few different issues:

1. Make sure that the switch is properly connected to the door release button. The switch may have been installed incorrectly during the repair process, which could prevent it from engaging properly.
2. Check the door release button to ensure that it is not damaged or malfunctioning. The door release button could be preventing the switch from engaging properly.
3. Check the wiring connections to the switch and door release button to ensure that they are secure and not damaged.
4. If you are having difficulty assembling the microwave, I suggest you to try and get the service manual or a diagram of the assembly process for your specific model GE0103MB. You can try searching for it online or contacting Samsung customer service, as they may be able to provide you with the information you need.
5. If the problem persists, you may want to contact a qualified technician to service the microwave and inspect the door switch and door release button.

It's important to note that working on a microwave oven can be dangerous and should only be attempted by someone who is familiar with the inner workings of the device, and have the proper tools and equipment.

You can disassemble the microwave oven and check out the release mechanism. You'll find several hooks that hold the door closed and a linkage mechanism to the door opening button. There may be a broken piece of plastic or maybe just a loose or missing screw that holds linkage together. In the case of a broken plastic part, you can fix it with a 2-part epoxy adhesive, but you'll need to permanently splint across the break with a piece of metal or strong plastic that you've scavenged from somewhere. Before epoxying the splint in place, rough up all plastic surfaces where you want the epoxy to stick well.
Good luck.

1. Open leverCheck your microwave lever to determine if it is damaged. If it is broken, simply replace the lever to get your microwave door fully functional again.
   
2. Door springResponsible for keeping downward pressure on the door hook, the microwave door spring can begin to malfunction. If this part is broken and prevents you from opening your microwave door, replacement is necessary.
   
3. Door latchOne reason your microwave door may not open properly is a broken door latch. Located inside the microwave, the door latch manipulates the door hook to keep the door closed for safety and top performance. If broken, the door could become stuck in the locked position.
   
4. Door hookIf your microwave door will not release properly, the door hook could be damaged. Located inside the door, the door hook is made of plastic and prone to breakage with extended use or age. As this part is unable to be repaired, the only option is to replace it.
   
5. Button or button springIf the microwave door will not open, it could be an internal failure of the button or button spring. If it is determined that either of these parts is the source, both are replaceable and it is recommended that they be installed at the same time.
   
6. Handle actuatorIf the microwave door will not open the plastic handle actuator could be broken. Connected between the door button and the door latch assembly, this plastic part could become damaged and brittle over time, which makes breaking inevitable. If this occurs, replace the handle actuator to get your microwave fully functional again.

Hi

If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work. You should check the internal door switches, the high voltage circuitry and the circuit board for this kind of problems. But for that you will need a certified technician to help you make these repairs.

Do not pry the door open since there is an easier remedy which will lead you in the direction that you need to fix your problem. Take the cover off after you disconnect the power to it. Once you have taken the cover off (only a few screws) you will be able to see the two latches that hold the door closed and the link that opens both of them. You can just lift both latches at the same time and it will open. After you have done that take a good look and press in on the open door button and you will see where you have the problem of the door hanging. That button should push a linkage that pushes up on both latches at once to open the door. It is spring loaded so that it comes back down so that when you close the door it will hold the door close.You need to take the cover off the microwave so that you can pull both of the latches that hold the door closed up. When you push the button in it engages a linkage that pushes both taches up at the same time to open the door. It is springloaded and will come back down during normal operation to hold the door closed when you close it again. That area is where your problem is. By looking at what happens when you press the open door button you should be able to readily see where the problem lies in that linkage

Most microwave ovens have catches that are shaped like hooks, these hooks catch on a fixed bolt or a raise in the frame of the oven.

The next time you get the oven open check these hooks to see if the springs are working in a strong positive manner, or if you have to push a button on the model check to see that the button releases the hooks.

Hope this helps.

If you push in on the open door button and it just goes in and does not open the door, then the problem is that the plastic piece that actually opens the door has broken. You can verify this by removing the cover from the microwave and look inside. If you are handy just buy the part from the panasonic parts store in your city and replace it. If not take it in and they will replace it for you.

Good luck
