Kenmore Dryer Error Code: F70 & F71

Your Kenmore dryer is designed to make your laundry experience smooth and efficient. However, like any complex appliance, it can occasionally run into technical issues. One of the error codes you might encounter is F70 or F71, indicating a lack of communication between the electronic control board (ECB) and the user interface control board assembly (UICB). In this article, we’ll delve into what these error codes mean and how to effectively troubleshoot and resolve them.

Deciphering the Error Code:

When your Kenmore dryer displays F70 or F71, it’s essentially telling you that there’s a breakdown in communication between two crucial components: the electronic control board (ECB) and the user interface control board assembly (UICB). These components play pivotal roles in the dryer’s operation, and their inability to communicate can result in the appliance’s malfunction.

Troubleshooting Steps:

1. Safety First: Before diving into any troubleshooting, ensure your safety by disconnecting the power supply to the dryer. This step is crucial to prevent any electrical mishaps.
2. Inspect Wire Harnesses: Visually inspect the wire harnesses connecting the ECB and the UICB. Look for any visible signs of damage, disconnection, or wear. If you find any issues, consider repairing or replacing the affected wiring.
3. Multimeter Testing: To perform a more thorough examination, use a multimeter to check the wire harnesses for continuity. This step will help identify any hidden or intermittent electrical faults that may not be visible during a visual inspection.
4. Professional Assessment: If both the visual inspection and multimeter testing reveal that the wire harnesses are in good condition, the problem may lie with the main electronic control board and the user interface control assemblies. In such cases, it’s advisable to seek professional assistance.

When to Consider Replacements:

If the wire harnesses are in good shape, you may need to replace the main electronic control board and the user interface control assemblies. These components are critical for the dryer’s operation, and their replacement can often resolve the F70 or F71 error codes, restoring the appliance’s functionality.

Resolving error codes like F70 and F71 can be a challenging task, especially if you’re not familiar with the inner workings of your Kenmore dryer. In such cases, it’s best to seek the assistance of experienced technicians who understand the intricacies of your appliance.
