Dealing with the Frustrating F04 Error Code on Your Whirlpool Dryer?

Imagine this – you’re in the middle of a busy week, working hard to catch up on laundry, when suddenly, your Whirlpool dryer displays an error code: F04. Panic starts to set in as you wonder what this code means and how it could possibly be fixed. But fear not, for I am here to guide you through resolving this frustrating issue!

Understanding the F04 Error Code:

The F04 error code on your Whirlpool dryer indicates that the outlet thermistor is shorted. Now, I know that might sound technical, but fear not, I’ll break it down for you.

What is an Outlet Thermistor?

An outlet thermistor is a small component located near the outlet vent of your dryer. Its purpose is to monitor and regulate the temperature during the drying process. It ensures that the dryer doesn’t overheat or underheat, thus protecting your clothes and preventing potential damage to the appliance.

What Does a Shorted Outlet Thermistor Mean?

When the outlet thermistor is shorted, it means that there is a disruption in its electrical circuit. This can cause inaccurate temperature readings or even prevent the dryer from functioning altogether.

How to Fix the F04 Error Code:

Now that we understand what the F04 error code represents let’s move on to the most important part – fixing it! Follow these steps to get your Whirlpool dryer back up and running:

  1. Turn off the power: Safety first! Before you begin any troubleshooting or repair work, make sure to disconnect your dryer from the power source. This will prevent any accidents or electric shocks while you’re working.
  2. Locate the outlet thermistor: Remove the dryer vent and turn your attention to the outlet vent area. The thermistor is often attached near or within this area. If you’re unsure, consult your dryer’s manual or look for online resources for further guidance.
  3. Check for damage: Inspect the outlet thermistor for any visible signs of damage such as burn marks, frayed wires, or loose connections. If you notice any issues, it may be necessary to replace the thermistor entirely.
  4. Test the thermistor: With a multimeter set to the ohm setting, carefully test the resistance of the outlet thermistor. Compare the reading with the manufacturer’s specifications to determine if it falls within the acceptable range. If it doesn’t, you’ll need to replace the thermistor.
  5. Replace the outlet thermistor: If the thermistor is indeed damaged or not functioning correctly, it’s time to replace it. Purchase a new thermistor compatible with your Whirlpool dryer model and carefully install it according to the manufacturer’s instructions.
  6. Restore power and test: Once the new outlet thermistor is in place, reconnect the power to your dryer and run a test cycle. Check if the F04 error code is no longer displayed and if your dryer is operating normally. If the error persists, it may be a sign of a more complex issue, and it’s advisable to seek professional assistance.


The F04 error code on your Whirlpool dryer can be frustrating but is generally manageable with a bit of troubleshooting and some DIY skills. By understanding the purpose of the outlet thermistor and following the steps outlined above, you can fix the F04 error code and get back to your laundry routine in no time. Remember, though, if you encounter any difficulties or feel unsure about the repair process, don’t hesitate to seek professional help to ensure your dryer is functioning safely and efficiently.

Key Takeaways:

  • Don’t let the F04 error code on your Whirlpool dryer ruin your laundry day! Understanding the outlet thermistor and following the DIY steps can help you fix the issue and get back to drying your clothes hassle-free.
  • Regularly cleaning the lint filter and inspecting the vent can prevent error code F04. If the issue persists, seek professional assistance to ensure your dryer functions safely and efficiently.
