Common Problems With Whirlpool Dryer F70 Code

Problems With Whirlpool Dryer F70 Code

The F70 error code is caused by a lost connection between the printed control circuit and the electronic console. The breakdown can be severe and hard to repair. However, there are a few cases that are easily repairable. Be on the lookout for some Whirlpool dryer models that display the F10 error code as the F70 error code.

This can cause a problem during Whirlpool dryer troubleshooting. The problem can also be a wiring issue or a failure of the central module. Below are the leading causes of the F70 error code on a Whirlpool dryer.

  1. Wiring damage
  2. Breakdown of the console board
  3. Breakdown of the central module

1. Wiring Damage

Loose wiring connections between the console board and central module board can cause F70 error codes. As mentioned earlier, Whirlpool dryers feature several electrical components and wires connected. Wire connectors leading to the main board can become loose over time. The wires can also become loose from knocks.

The person servicing or repairing the dryer can also forget to tighten them. There are also chances of wires rusting over time. Whatever the reason, a bad wire connection on the main control board and console board can lead to the F70 error code.

2. Breakdown In The Main Control Board

The main control board is the brain of the dryer. It is usually present on all dryers and home appliances. There are usually several components on the control board. The control board takes all the dryer settings and coordinates different parts to run the dryer. The components here also control the OFF and ON mechanism of the dryer.

A failure of a single component on the control board can affect the dryer. Typical breakdown issues arise from power surges and regular wear and tear. Exposure to excess heat and moisture can also cause damages leading to the error code.

Lastly, a breakdown on the user interface board can also trigger the F70 error code. The Cabrio dryer F70 error indicates an overload that the main control board has recognized on Cabrio dryers.

3. Breakdown Of The User Interface Board

The User Interface Board is located behind the control panel. It features several printed components that work together to control the buttons and create displays. This is what allows you to control the dryer settings. A failure in the user interface board can lead to an F70 error code.

There are several components on the electronic board that can fail. It can be worn out due to many years of use or suffer from power surges. Exposure to excess heat, moisture, and water can also affect it. Make sure you perform visible observations for any signs of damage.

Step By Step Solution To Fix Whirlpool Dryer F70 Error Code

  6. Get the new control board and fix it. Connect back all electrical components and wires as shown on the manual
  7. Mount the board back and screw it in place. You can then close the access panels and test the dryer for the F70 error code.

3. Repair/Replace The User Control Board

The process of fixing and replacing the user control board is quite similar to that of the main circuit board. You need to do the following:

  1. Disconnect the dryer from the main power supply
  2. As usual, have the technical sheet and manual for reference
  3. The user control board is located behind the control panel. Remove the dryer’s top access panel
  4. Take out the user control board by unscrewing the mounting bracket
  5. Gently remove the electrical connector and any other attachment
  6. Take out the main user interface from the mounting bracket
