How To Fix Microwave Door Latch – 6 Easy Ways To Fix

Is your microwave door latch not working, and don’t know how to fix microwave door latch? I have faced the same situation. After coming back from the office, I was so hungry that, in a hurry, I put some food in my Samsung microwave to heat up.

Guess what happened? To add to my misery, the microwave door wasn’t latching or closing at all. I tried pressing the button and restarting it again, but still nothing.

That’s when it struck me, and I realized my microwave door latch wouldn’t work because no matter how much I tried, the door wasn’t closing, and the button wasn’t working either.

It was my first time experiencing something like this, but it triggered me to think how miserable one would feel if the door latch breaks when one needs the microwave the most.

So, I thought, why not study a bit and come up with all the reasons and fixes so that you don’t end up like me, hungry and confused? What are we waiting for, then? Let’s get started.

How To Identify If Microwave Door Latch Is Broken?

Before jumping on to problem-finding and professional help for repairing, try these four easy methods to know whether your microwave door latch is broken or not.

And, of course, to make it work again like before.

Method 1: Check if the latch is stuck

The first thing you should do is check whether the latch is disconnected from the door because of being stuck. Here’s how you rule out the possibility of the microwave door latch being stuck:

On the one hand, press the door button, and on the other hand, pull the door manually. If you can open the door only when you’re pulling it but not with the button, then look for any stuff, such as debris or food.

Clean the latch if you find anything stuck, and if not, then it’s time to move on to the second method.

Method 2: Check if the door latch button is operating

This step is only applicable if your microwave has a button that is used to open the door. Or else you can move on to the next step.

For those with a microwave door latch button, press the button. If you can feel pressure, that means the button is working fine.

If there’s no resistance, the button is broken or needs to be reattached properly. Also, if you hear a clicking sound, that means the button is defective.

In this step, you can easily fix the problem without professional help. What you need to do is-

  • First, turn off the microwave and detach the whole control panel.
  • Then, reattach the button to the correct position. If you find any compartment broken, then you need to replace the whole button unit.

So, you just need to get a new button unit, replace the door button and reattach the panel. If the microwave latch doesn’t start working, follow the next step.

If you see sparks in the microwave, please see my previous troubleshooting.

Method 3: Check the lever of the latch

The latch lever is the part that opens the door whenever you press the door button or try to open it using the handle.

If the lever is faulty, the latch becomes unusable. Now you are wondering how you are going to check and replace it. Well, here’s how you’re going to do it.

To get access to the latch lever, remove your microwave from the power supply and separate the control panel. Now, look for the latch lever, a small plastic that you’ll find within the latch. If it’s stuck or not in its place, free the lever.

You know what to do if the lever is broken. Buy a new one and replace it. If still, the microwave latch doesn’t work, then there’s only one method left.

Method 4: Check the Door Hinge, Spring, and Side Latch

Within the microwave door, you’ll find the latch unit. That’s where all these parts are situated. Whenever these parts are not working properly, your microwave door latch starts to throw tantrums.

Methods of checking the parts of the latch unit and replace if necessary are as follows;

  • Turn off the microwave’s power button to ensure no electric accident happens.
  • Take off the microwave door so that you can examine the internal parts without any problem.
  • To remove the door, detach the internal unit and unloose the door hinges. Look into the user manual to become familiar with these steps.
  • Now, check the hinges, side latch, and spring. If any of these parts are damaged or worn out, you need to replace them.
  • You just need to buy the parts from the store simply to replace them. Make sure the parts are the same brand as your microphone.
  • Then, replace the parts with the new ones. And reattach the door.

If you try these four steps, you’ll not only know whether your microwave door latch is broken or not. You’ll also be able to solve them.

Why Is My Microwave Door Latch Not Working? 8 Reasons

After finding out that your microwave latch does have issues, there are also other reasons that might be responsible for your door latch not functioning properly.

The possible reasons are-

  1. The door and the latch are not cleaned properly.
  2. There’s an issue with the microwave latch assembly.
  3. The door latch itself is broken.
  4. The torsion springs of the latch are broken.

The Door and Latch are not Cleaned Properly:

Before finding out what to repair, you should make sure whether you actually need to repair the microwave door latch or not.

Because of overuse and not maintaining hygiene, food particles often build up in the microwave. Mostly grease is stuck between the door and the latch.

If you’re unable to close the microwave door, the door and the latch not being clean might be the reason.

An Issue with the Microwave Latch Assembly:

The microwave doors normally have one or two latches connecting with the switch through an alcove. The microwave starts only after the switch is engaged with the door hook.

So, as you can understand, there’s a whole system going on here. There are several issues that may occur here.

First, the door hooks and springs may lack tension. So, the hooks will not connect with the switch to turn on the microwave.

Second, the switch itself can be broken or damaged.

The Door Latch Itself is Broken:

If you find out the switch and hinges are working just fine, then there’s a high possibility that the latch itself is broken.

The door latch is in the inner panel of the door and clenched by a plastic tang. So, just remove the inner panel, and you can see for yourself if the latch is broken or not.

Even if the latch is small, it’s essential to close the door and connect the microwave to the switch.

The Torsion Springs of the Latch is Broken:

The torsion springs might be broken if your microwave door is not latching or closing. Torsion springs help to close and open the door.

You can locate the torsion springs just by removing the door panels. After that, you can access the springs and replace them if they are broken.

The Software Problem:

Sometimes the software of the microwave starts to act up and show wrong signals because of overusing or unstable power connection. This might even lead to the door latch assembly not working properly.

So, if your microwave door latch does not work properly, you need to check whether the microwave software is working perfectly or not.

The Door Frame is Damaged:

Whenever an issue occurs with the hinges, this might also affect the door’s frame. If the frame of the door is damaged, the door won’t be latched or closed.

Even if you forcefully shut the door, the microwave won’t start.

The Control Panel Is Not Functioning:

As the button and the switch are also a part of the microwave, this may signal that the microwave’s control panel is not functioning as it’s supposed to.

Possible reasons for a non-functioning microwave control panel could include a power issue, a faulty control board, or a malfunctioning keypad.

Even if the button and switch are fine, if the control panel is faulty, the system won’t work. As a result, the door won’t be latched.

The Lock is Broken:

If the lock that helps the door to latch is broken, the microwave door will show signs of failure, such as not closing, opening, or latching.

It may also not heat properly or make strange noises. Additionally, the interior light may stay on when the door is closed.

It is important to replace the broken lock as soon as possible in order to ensure the microwave is functioning correctly and safely.

Whirlpool has different functions, so whenever there’s something wrong with the door or the latch, the device keeps displaying “door error.”

This door error can happen for four different reasons. The reason along with solutions, are as follows:

Replace the spring by opening up the latch assembly that’s inside the control panel using a drill and screwdriver.
