Whirlpool Microwave Door Switch Wiring Diagram: A Comprehensive Guide

Are you experiencing issues with your Whirlpool microwave door switch? Do you want to know how to replace or fix it on your own? In this article, we will discuss everything you need to know about Whirlpool microwave door switch wiring diagram. We will help you understand the different components of the switch and provide step-by-step instructions on how to replace it. Let’s get started.

Understanding the Whirlpool Microwave Door Switch

The Whirlpool microwave door switch is an essential component of the appliance that ensures safe operation. It is responsible for detecting whether the door is closed or open. The switch is located behind the control panel of the microwave and is activated when the door latch hits a small lever attached to the switch. When the switch is activated, it signals the control board to allow the microwave to operate. If the door is open, the switch will not activate, and the microwave will not function.

Now that you understand the purpose of the door switch, let’s discuss the wiring diagram and how it works.

Whirlpool Microwave Door Switch Wiring Diagram

The wiring diagram for the Whirlpool microwave door switch is relatively simple. It consists of three wires that connect to the switch terminals. Here is a breakdown of the wiring:

Wire Terminal Description
White C Common wire
Black NO Normally open wire
Red NC Normally closed wire

The common wire (white) is connected to the center terminal (C) of the switch, while the normally open wire (black) is connected to the terminal marked NO. The normally closed wire (red) is connected to the terminal marked NC. When the door is closed, the switch is activated, and the normally open circuit is closed while the normally closed circuit is open. When the door is open, the opposite occurs.

Replacing the Whirlpool Microwave Door Switch

If your Whirlpool microwave door switch is not functioning correctly, you may need to replace it. Here are the steps to replace the door switch:

Step 1: Unplug the Microwave

Before you start the repair process, make sure to unplug the microwave from the power source. This step is crucial to prevent any electrical shock or injury.

Step 2: Remove the Control Panel

To access the door switch, you need to remove the control panel. The control panel is usually held in place by several screws located on the top or sides of the microwave. Once you remove the screws, gently pull the control panel away from the microwave.

Step 3: Locate the Door Switch

The door switch is usually located at the top or bottom of the control panel. It is a small rectangular-shaped component with three prongs or terminals.

Step 4: Disconnect the Wires

Using a pair of pliers, carefully pull the wires off the switch terminals. Make sure to note which wire goes where for reassembly.

Step 5: Install the New Switch

Take the new door switch and connect the wires to the appropriate terminals. Gently push the switch back into place and reattach the control panel using the screws.

Step 6: Test the Microwave

Plug the microwave back into the power source and test it to make sure the door switch is functioning correctly. If everything works correctly, your repair is complete.
