The microwave is an important appliance in our kitchens, helping us to prepare meals and snacks rapidly. One of the most popular microwave brands is Whirlpool, known for its high-quality and reliable home appliance products. 

However, over time, your microwave can malfunction, and you may encounter issues and errors,  such as the door error. The door error is a common problem that can be frustrating and inconvenient and even leave you unable to open your microwave. 

Below, we’ll discuss everything you need to know about the Whirlpool microwave door error and how to fix it.

Signs of a Whirlpool Microwave Door Error

Before we jump into the ways to fix a door error, it’s crucial to understand how you can identify if your Whirlpool microwave has this issue. 

The most common sign is a beeping sound coming from the microwave. The beeping is usually accompanied by an error message that reads “open/close door.” 

If your microwave does not start and displays this message only when trying to start it, it could be that the door is not closed correctly. 

Another sign is if the microwave turns on, but the turntable inside does not move.

Steps to Fix a Whirlpool Microwave Door Error

If you experience any of the signs of a door error mentioned above, don’t worry. Here are some simple yet effective steps to fix the problem:

Close the Door

The easiest fix for a Whirlpool microwave door error is to simply close the door. This error most commonly occurs when a command has been entered into the microwave’s control panel, but the door has not been closed, so the microwave cannot cook your food.

Shutting the door firmly should result in your microwave starting.If the door does not shut, however, then there may be some other issues at play. Read on for more help on getting your microwave cooking again.

Step 1: Clean the Door and its Surroundings

If the above-mentioned steps do not fix the issue, it could be that the door error is caused by dirt, grease, or food debris around the door. Gently clean the door and its surrounding area using a damp cloth. Make sure you clean the door hooks and the latch assembly carefully. Once done, test your microwave again and see if the issue persists.

Step 2: Check the Door Latch

The first step to fixing a door error is to check if the door is latching correctly. Gently push and pull the door to test the resistance. If you feel it fall freely, it means the latch is not properly aligned. Check the metal door latch and ensure it isn’t damaged or bent. If the door does not latch correctly or is damaged, you will need to replace the door latch.

Step 3: Check the Door Hooks

While you’re inspecting the door, make sure you examine the door hooks thoroughly. The door hooks are the plastic clips that hold the door securely. Ensure they are not broken or damaged. If they are, replace them with new hooks.

Step 4: Check the Door Button 

The button that opens the door can also wear down over time, and it can become harder to fully close or open the door if the button’s mechanisms do not catch or release the door hooks as they should.

Test the door button by slowly pushing the door in. If there is a click, then the hooks have engaged to shut the door.

Next, test the button. If the button is slow to move or moves too quickly and does not release the door hooks, then you will need to replace the door interlock mechanism.

Instructions for how to do this can be found below.

Step 5: Check the Door Interlock Switches

Safety note – Microwaves carry extremely high voltages and remain a voltage safety risk even when unplugged. If you are not comfortable with DIY projects, contact a Whirlpool repair technician to fix your microwave. If you choose to proceed, use all necessary precautions when your microwave is open.

Another possible cause of the Whirlpool microwave door error is an issue with the door interlock switches. The interlock switches are safety mechanisms installed in the microwave to ensure the door is correctly closed before it can function. 

The first step is to unplug the microwave.

From there, you will want to move the microwave so you have full access to it.

Remove any screws holding the exterior cover in place. These are typically found along the bottom of the frame. Remove the exterior cover.

Behind the keypad, you will see three small rectangular devices about the size of a USB drive. These are your interlock switches.To replace them, simply disconnect them. You may need a pair of pliers to reach their release tabs.

Now, as you remove the switches, test them for continuity. Each switch should have a small button on it, and the continuity should change when the button is pressed. One will have continuity when the button is pressed. This is your normally closed switch. The other two will lose continuity when the button is pressed but retain it when the button is not pressed. 

You will need to buy replacement switches. You can do this at any appliance repair shop.

Reinstall the normally closed switch in the slot closest to the body of the microwave.

Install the other two in the other two slots.Then replace the exterior cover, and screw it back on,

Move the microwave back into position and plug it in.

Test the microwave for functionality.

Step 6: Call an Expert

If all the steps mentioned above don’t fix the door error, it’s best to call a professional. They have the necessary tools and expertise to fix the problem.

A Whirlpool microwave door error can be frustrating, but it is fixable. You can follow the steps mentioned above to identify the problem and resolve it. 

Checking the door latch hooks, cleaning the door, replacing the interlock switches, and finally, calling in an expert are all viable solutions, depending on the cause of the door error. 

Remember, taking care of your microwave and regularly cleaning it can help prevent issues like these from occurring in future.
