The Whirlpool Oven is one of the best appliances you can own in your household. It’s a vital kitchen appliance that will save you much time and energy to reheat food and snacks.

At any point, the oven can malfunction or stop working effectively. It’s an inevitable situation that every appliance encounters. The malfunctions can be from system glitches or user-related faults. Sometimes, it can be that a component is faulty.

Whatever the cause of the problem is, you’ll want to troubleshoot it and fix your oven immediately. The troubleshooting process can be rigorous and time-consuming.

This article will clarify everything you need to know about the diagnostic mode and how you can use it.

What Is The Diagnostic Mode On Whirlpool Oven?

The diagnostic mode is an inbuilt feature on the oven that helps with identifying problems with the machine. It helps demystify and pinpoint the problem source.

If your oven stops working, you might be unsure of what’s the problem or which parts to diagnose. Rather than guessing around and analyzing all components hoping to find luck somewhere, you can employ the diagnostic mode to help you identify the problem source.

The diagnostic mode can assist you in narrowing down the component causing the problem. Generally, it’s a way of interacting with the control. You can have it run specific operations and perform a self-check to determine the particular situation.

Whirlpool Oven Diagnostic Mode: How Does It Work?

When you run the diagnostic mode on your Whirlpool oven, it can help you detect what is going wrong or what went wrong with the system.

It works by running tests on every major component of the oven necessary for smooth operation.  It inspects the working condition of these components to determine if there’s any problem somewhere.

It performs a self-check and displays data about the operation. If it detects a problem, it displays an error code(or flashes light in models without a display screen) as part of the diagnosis.


The purpose of the error code is to inform you of the possible cause of the problem based on the algorithms programmed into it. The error code is a great data point that guides your troubleshooting process. You can then interpret the error code and tackle the specific component accordingly.

How To Run The Diagnostic Mode On Whirlpool Oven

The diagnostic mode makes it easy to identify and fix problems related to the oven. The error codes displayed makes it easier to figure out the part to troubleshoot or fix so you won’t waste your precious time correcting the wrong part.

How the diagnostic mode is implemented varies across models. However, irrespective of the Whirlpool oven model you use, the process is simple and DIY. It only involves pressing some specific keys/button combinations on the control panel. You can enter the diagnostic mode in two possible ways.

Follow the step-by-step guide below to start the diagnostic mode on your Whirlpool Oven:

  • Put your oven in standby mode
  • Locate the buttons in the control panel
  • Choose any three buttons you like except the Power, Start or Stop key
  • Press these three keypads three times in a row. Ensure you maintain the order in which you press the first round.
  • Simply put, you’ll press three buttons three times in a row while maintaining the order. So, you’re pushing the buttons nine times.
  • For instance, if you use a single oven, you can press the Home == Favorites == Light buttons and repeat twice.

Note that you don’t need any confirmation, such as visual or sound feedback between the button presses from the control.

The process should put your machine in diagnostic mode immediately. If it doesn’t enter, repeat the process as we described above. Double-check the buttons you’re pressing and confirm they are in good working condition.

When your machine enters the diagnostic mode, you can scroll through the menu and jump to any selection using the display touchscreen functionality.

Alternatively, you can enter the diagnostic mode with the steps below:

  • Use the touchscreen to jump to the Menu
  • Select Tools and click the Info option
  • Go to the Service and Support menu and select it
  • Press the diagnostics button for about a minute
  • Now press buttons 1, 2, and 3 three times in that order
  • A warning will display. Press Enter to confirm

The machine will enter the diagnostic mode with this process. If it doesn’t, continue repeating the button sequence as described above. To confirm if your engine has entered the diagnostic mode, check the keypads. The indicator lights will flash. You can now scroll to the desired selection using the machine display touchscreen.

Let the self-test mode run without any interruption. If it encounters a problem, it’ll return an error code. You’ll need to interpret the code and work on the components that require diagnosis immediately. If you don’t understand each error code, visit your owner’s manual or manufacturer’s website for clarity.
