What Is The F1 Code On Whirlpool Drye?

The F1 code on a Whirlpool dryer is an error message that typically indicates a malfunction in the dryer’s main control board. This error can occur due to various reasons, such as electrical issues or a faulty board itself. To address this problem, you’ll need to access the control board, disconnect the power supply, and replace the malfunctioning main control board with a new one. While it may seem like a daunting task, following a few simple steps can help you resolve this issue and have your dryer working smoothly again.

What Causes the F1 Error Code?

The F1 error code on a Whirlpool dryer can be caused by several factors, including:

Faulty Main Control Board: The most common cause of the F1 error is a malfunctioning main control board. This component is responsible for regulating various functions of the dryer, and if it fails, it can trigger the error code.

Wiring Issues: Loose or damaged wires, connectors, or harnesses within the dryer’s electrical system can disrupt communication between components and lead to the F1 error.

Power Surges: Electrical power surges or voltage fluctuations can damage the main control board and trigger the error code.

Environmental Factors: Excessive moisture, humidity, or exposure to extreme temperatures can adversely affect the control board’s performance and lead to errors.

User Interface Problems: In some cases, issues with the user interface control (the dryer’s control panel) can also contribute to the F1 error.

How To Fix the F1 Code On Whirlpool Dryer?

Here’s a step-by-step guide to troubleshoot and fix the F1 error code on your Whirlpool dryer:

Accessing the Main Control Board

Remove the top panel of your dryer to access the main control board. To do this, follow these steps:

  • Locate and remove the three-quarter-inch screws at the back of the dryer.
  • Depending on your dryer’s positioning, you may need to move it slightly to access these screws.
  • Use a quarter-inch drill with a 90-degree angle adapter to make this task easier.
  • Once the screws are removed, gently push the top panel back to release it. It’s held in place by slides at the front, and it should come off easily.

Identifying the Main Control Board: The main control board, responsible for the F1 error code, is typically located on the top left-hand side of the dryer. It’s a vital component that controls various functions of your dryer.

Disconnecting the Connections: Carefully disconnect all the wires and connectors from the main control board. You can snap pictures if you want to ensure you reconnect them correctly later, although it’s generally hard to put them in the wrong spots.

Removing the Faulty Main Control Board: 

  • Look for a single quarter-inch screw that secures the main control board in place. This screw can be a bit challenging to see due to its location.
  • Use your quarter-inch drill with a 90-degree adapter to remove this screw.
  • There’s a small tab at the bottom of the board that needs to be pushed in to release it.
  • Gently pull the board towards you, and it should come out easily.

Installing the New Main Control Board

  • Replace the faulty main control board with a new one. Ensure it’s properly seated.
  • Reattach the quarter-inch screw to secure the new board in place.

Reconnecting the Wires

  • Reconnect all the wires and connectors to the main control board. Use your pictures if needed to ensure correct placement.
  • Don’t forget the gray wire that connects to the user interface, as it’s crucial for proper functionality.

Powering Up and Testing

  • Turn the power back on to your dryer by switching the breaker back on.
  • Test your dryer to ensure it runs without displaying the F1 error code.
  • If you encounter an F2 error immediately after replacing the board, it may indicate an issue with the user interface, though this is relatively rare.

How To Prevent The F1 Dryer Error Code?

Preventing the F1 error code on your Whirlpool dryer involves some proactive measures to ensure the smooth operation of your appliance. Here’s how you can minimize the chances of encountering this error:

  1. Proper Installation: Ensure your dryer is correctly installed, with stable and level positioning. This helps reduce vibrations and potential damage to internal components.
  2. Surge Protection: Use surge protectors or voltage regulators to safeguard your dryer from electrical surges or fluctuations, which can damage the control board.
  3. Regular Maintenance: Perform routine maintenance, such as cleaning lint filters and exhaust vents, to prevent lint buildup, which can affect the dryer’s performance.
  4. Avoid Overloading: Don’t overload your dryer with excessive laundry, as this can strain the motor and other components. Follow manufacturer guidelines for load capacity.
  5. Check Wiring and Connections: Periodically inspect and tighten any loose wiring, connectors, or harnesses within the dryer’s electrical system.
  6. Environment Control: Ensure your dryer is placed in a dry, well-ventilated area with controlled humidity and temperature levels. Avoid extreme environmental conditions.
  7. User Interface Care: Treat the user interface (control panel) gently, avoiding excessive force when using buttons and controls.
  8. Regular Inspections: Keep an eye on your dryer’s performance and be vigilant for any unusual noises, error codes, or signs of malfunction. Address issues promptly to prevent further damage.


Is it necessary to disconnect all the wires when replacing the main control board?

Yes, it’s crucial to disconnect all wires and connectors from the main control board before replacement.

Can I use pictures to ensure I reconnect the wires correctly?

While you can take pictures, it’s usually not necessary as the unique shapes of the connectors make it difficult to reconnect them incorrectly.
