Panasonic s550bf Door Latch

Hi I accidentally broke the top door latch off my panasonic s550bf and now the Microwave won't turn on. The latch mechanism is still intact but I guess there is a sensor inside the frame that won't allow the microwave to turn on. How can I replace the latch or fix the sensor?

Re: panasonic s550bf Door Latch

Do you still have the piece that broke off? If so, you may be able to use two part epoxy to glue it back in place. I did this with a colaric MW and it did the trick. The latch was hook shaped and made from a hard plastic. Pete

Maytag MMV4205 door won't stay shut.

After tearing apart my microwave, I found a little spring broke off the latches. Open the door to the microwave, pop off the plastic piece that the latches on the door go through. You will see a spring behind the latch. If the spring is not connected to the latch it won't operate properly. The spring was held onto the latch with a tiny plastic piece that broke off. An easy solution instead of buying a new latch is to heat up one side of the spring without burning yourself and melt it through the latch piece where it was originally connected then put everything back together.
Hope this helps,

Door will not close without slamming

Possible causes - door switch, or door switch assembly out of adjustment; plastic latch guides on door switches worn; door hinge worn, causing door to be out of alignment. If it's the last one, the unit needs to be checked for microwave radiation.

Frigidaire microwave won't start when door is closed. It looks like the door does not latch properly. It worked 20 minutes ago and last night. How do you troubleshoot and/or fix the switches.

Hello Scott Noble - If I was in your position, I personally will recommend consulting a certified technician first for an accurate diagnosis. Depending on what part(s) is damaged from the door, the microwave could possibly have faulty switches, door switches, or latch which only a professional can repair.

Open Lever If the microwave door won't open the open lever might be broken. This part can be replaced separately.

Door Spring If the microwave door won't open the door spring may have broken. The door spring is located inside the door and keeps downward pressure on the door hook.

Door Latch If the microwave door won't open the door latch might be broken. The door latch is inside the microwave. The door hook, which is part of the door, engages with the latch to keep the door closed during operation. If the door latch or actuator breaks the door may not open.

Door Hook If the microwave door won't open the door hook might not be releasing properly. The door hook is installed inside the door and normally releases when the door is opened. The hook is made of plastic and will break over time. When this happens it will need to be replaced, it can't be repaired.

Button Spring If the microwave door won't open the button spring might be broken internally. The button spring can be replaced.
Button If the microwave door won't open the button might be broken internally. The button can be replaced.
