The F01 error on your Whirlpool dryer means there is an issue with your control board. It is often displayed after a power surge or failure. There are several things you can do to get your dryer up and running again before having to call in the experts. 

This is a step-by-step guide that explains how to fix an F01 error code on a Whirlpool Dryer. 

The following Whirlpool dryer models are covered in this guide:














Reset the main control 

First, reset the main control. This is a simple fix that reboots your dryer and often will solve your problem. To reset your Whirlpool dryer’s main control, simply unplug your dryer from its power source. This will reset the main control. It is recommended that you wait a few minutes before you plug it back in. After it has been reconnected to its power source, turn it back on and see if the error has been resolved. If not, move on to the next step.

Check the thermal switch

If resetting the main control didn’t fix the error, the next step is to check some of your dryer’s internal components. The first component you will need to check is the thermal switch. 

The thermal switch is responsible for protecting your dryer against overheating. While it does not usually cause the F01 issue, it can be the difference between a $20 vs. a $200 part. The thermal switch may be located on the blower body, heating element, or gas burner, depending on the make and model. 

Follow these simple steps to check the thermal switch:

  1. Power off your dryer and then unplug it from the wall so it is safe to work on. 
  2. Unscrew and remove the bottom panel from the front of the dryer. 
  3. Locate the thermal switch. 
  4. Check the switch for continuity by connecting the two wires to a multimeter. 

If there is no current, then your switch will need to be replaced. If the switch is working as it should, then put the wires back and move on to the next step. 

Check the thermistor

The next component you will need to check is the thermistor. This is a more common reason for the Whirlpool dryer to display an F01 error. 

Follow these simple steps to check the thermistor:

  1. Power off your dryer and then unplug it from the wall so it is safe to work on. 
  2. Remove the bottom panel if you haven’t already. 
  3. The thermistor is usually located to the left of the thermal switch on the fan housing. Check your manual if you’re having trouble finding it. 
  4. If necessary, dismantle the filtration channel housing to gain access to the thermistor.
  5. Check that the wiring is not damaged, in good condition, and still intact.
  6. Check the continuity using a multimeter, like you did for the thermal switch. 

If there is no current in your thermistor, it will need to be replaced. If the thermistor is working as it should, then put the wires back and move on to checking the door switch. 

Check the door switch 

The next component you want to ensure is working correctly is the door locking mechanism on your Whirlpool dryer. The door switch is a safety switch that prevents the dryer from spinning after the door has been opened. If the door is not locking as it should, it may cause the F01 error to be displayed. 

Follow these simple steps to check the door switch: 

  1. Ensure your dryer is not connected to a power source so it is safe to work on. 
  2. Locate the door switch, which is usually where your dryer door opens. 
  3. Remove the door switch. If unsure, check your manual as different models have different ways to remove the switch. 
  4. Using your multimeter, check the switch for continuity. 

If there is no current in the switch, it will need to be replaced. If the door switch is working, then check to see if the error has been resolved by reconnecting your dryer to a power source and turning it on. If the error persists, you will need to replace the control panel.  

Replace the control panel

If you have followed all of the steps above and are still seeing the F01 error, your final option is to replace the control panel. The control panel allows you to set the agitation, length, and temperature of the cycle. It is a crucial part of any dryer and also the most expensive part to replace. For this reason, you may want to consult a qualified technician or consider buying a new dryer. 

If you decide to go ahead and replace the control panel yourself, we suggest following these steps:

  1. Ensure your Whirlpool dryer has been disconnected from the power source so it is safe to work on.
  2. Remove the dryer panels if you haven’t already. 
  3. Use your manual to locate the control panel. You may need to dismantle a protective panel.
  4. Take a photo of the control board so you can see where the wires are connected.
  5. Once you have access to the control board, remove all connected plug fittings.
  6. Remove the screws used to keep the panel in place. A hex head ¼ should work.
  7. Carefully remove the control panel.
  8. Connect your new control panel in its place.
  9. Reconnect all the wires using your photo to ensure they are in the right location and screw them back into place. 
  10.  Replace all panels and reconnect your dryer to the power source. 
  11. Turn on your dryer and see if the F01 error has been fixed. 

If you are still seeing an error, you will need to consult a qualified technician. Other reasons for the error can include a burnt relay contact on the control panel or the wires attached to the control panel being damaged. Most Whirlpool dryers come with a one-year warranty, so it is worth checking to see if you are still covered before buying any parts.
