Tip & How-To about Maytag MMV4205 Microwave Oven

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 stay close


Not much data to go on here. The latch on the door has a spring that holds it down in the locked position. when you pull the handle the latch goes up and you pull the door open. You will have to take the door apart and see if the spring broke or the plastic tab that holds the end of the spring is broken.

emerson microwave door latch


I have an Emerson MW8999RD that all of a sudden yesterday wouldn't latch. I don't think you have to, but I took the door off (three screws hold the case on which needs to be removed to get at the top hinge). Then I took off the inner plastic picture frame - pretty easy with a thin blade to move the fragile tabs. Then I removed the metal frame that has the little microwave blocking holes. This was the hardest part because the plastic retaining tabs are even more fragile and I broke one. Then I found the loose spring due to broken plastic hook as described above. I was able to make a new hook by simply looping a small zip tie where the old plastic hook tip broke off. Now works great!

Sharp r520kst door won't stay shut


If the door will not stay closed it is the spring inside door, or the small plastic piece that holds the spring which is attached to the $80.00 piece called outer door.
To fix it, it is EASY and you do not have to even take the inside cover all the way off. Just remove the three sides of cover by gently slipping a plastic putty knife around rim to release the clips. Then attach the spring to the small hole below where the plastic piece used to be, which is located in the metal on the glass frame piece, use tweezers, hold the other end of spring as you place spring onto plastic door latch and set into place!
Snap the inside cover back on and YAY! FINI!

Door won't latch/microwave won't turn on


The door does come apart. Open the door and where the hinges are, there are openings where the hinges enter the door, this plastic piece (goes all the way around the door) With a small flat blade screws driver VERY carefully pry it (plastic) off, once off, check the latch end for the spring, typical failure for a Sharp is the little tab that the spring hooks to on the door, the only way to repair this so it will last is to replace the door frame. they are not too expensive, about $50 or so Part# FCOVB166KIT

Sharp Carousel Microwave door latch stopped working door won't stay closed


Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

We have *critical* safety & disassembly info at our site, linked here: http://tinyurl.com/yzjozk

We also have this full service manual at our site: http://www.microwavedisplay.com/R1480_R1481_R1482_sm.pdf

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

We're happy to help and we appreciate your thoughtful rating of our answer.
